✔️ Technical Problem and Patent Objectives
Harvesting, transportation and unloading of the product is an important issue that farmers and ranchers or grain wholesalers face every day, because to harvest a product such as straw or grain, labor and equipment such as excavators, tractors and .. need that it takes a lot of time and money. Transportation of straw and grain is very time-consuming due to the type of product, and during transportation, even the wind causes the product to fall, and more importantly, trucks and goods vehicles are needed for transportation. Product unloading for such small and light products requires the use of equipment such as excavators, conveyors, etc., which imposes a lot of costs on the farmer, rancher, and distributor.
The purpose of this invention is to provide a device that performs the process of harvesting, transporting and unloading grain and straw alone and eliminates all unnecessary labor and transportation costs, and more importantly, in the finished price of the product that It is up to the consumer to make a significant reduction. Description of the state of prior knowledge and history of developments related to the claimed invention. Grain and straw vacuum device is one of the agricultural equipments that is used to collect, preserve and transport grains and straw. By creating a negative pressure inside the tank, this device removes the ambient air from inside the grain and straw storage tank and causes the grain to be sucked through the tube entering the device tank and cleans the dust and transfers the grain without damage. This common device is used in grain and straw storage warehouses, agricultural fields and livestock farms. There are devices for harvesting, transporting and unloading grain and straw with different characteristics and functions in the world, each of which uses a special technical feature for vacuum, storage and transfer of grain and straw. The alleged device also has a special technical feature that makes the loading, storage and unloading operations completely innovative and new, so that there is no example with such a technical feature.

Providing a solution for the existing technical problem along with a detailed and sufficient description of the invention of the mechanized straw and grain transport device by creating positive and negative air pressure inside the cabin consists of six main parts, including: device chassis, cabin, transmission system Power, Mardon system, mixing system, fan system with air channels
✔️ The chassis of the machine
is an engineering structure made of steel profiles to install and maintain all the components of the machine on which there is a connection interface in the front part so that it can be transported and moved through tractors or other cargo vehicles. There are two manual jacks installed on the chassis side of the device, which when the device is installed in the place, these two manual jacks stabilize the device and bear the weight of the device. Two wheels are installed in the middle part of the chassis of the device, which is supported by metal profiles in the form of an engineering structure, which allows the device to be carried on wheels and has the ability to move and transport.
✔️ Cab
The cabin of the machine consists of three metal frames that are welded on the chassis with a certain distance, the frame of the cabin from the bottom side consists of four side frames of the bottom of the body and on the top side of the cabin consists of four side frames of the body with There are bent sheets that give the machine cabin an engineering shape and structural strength. In the upper part of the cabin, there is a bent sheet that is placed under the air intake roof channel along with the metal mesh of the roof channel, which is placed through the entrance channel. Air is routed to the roof duct to the air intake duct. At the end of the cabin, there is the back frame of the machine, which covers the entire metal frame, and in the upper part of this part, there is a grain suction valve, which, when the machine is in loading mode, air is sucked into the cabin from this part along with grain or straw. It becomes a device. The back door of the cabin is installed for the user to enter, so that the user can access the interior of the cabin when necessary, and it is designed in such a way that it can be completely locked by the cabin door lock lever and does not have air leakage. So that the user can To have access to the top of the cabin, a step and a ladder are installed in the end part of the device so that the user can use it in necessary situations.
✔️ Power transmission system
The power transmission system in the device is such that the garden shaft of the tractor is connected to the main shaft and by rotating it, it causes the main money of the device to rotate, which are all rotating on two bearings. The main money of the device is supported by four belts. It transfers the driving force to the polyfan, and the polyfan also transmits the rotational driving force to the fan through the fan shaft, which rotates on two bearings, and causes the air flow in the air suction channel and the air outlet channel.
The end part of the main shaft ends with a gear and clutch system, which is placed in free or engaged state by a clutch lever. If the clutch is engaged, the driving force is transferred to the larger gear through the gear on the main shaft through the chain, and then this gear, which rotates on two bearings, transmits the driving force through the wheel. The smaller gear transmits to the two Mardon gears by means of a chain, which causes the movement of the right Mardon gear to be reversed by means of a tightening chain. A pulley connected to the side of the gear is freely rotating and when the user of the operating lever stirs it. put it in the engaged state, the two belts transfer the driving force to the female pulley, and the female shaft, which is placed inside the two bearings, starts rotating and mixes the materials inside the cabin.
Mardon System
On the lower surface of the cabin, there are two hoppers, including the right hopper and the left hopper, which are rotated by the 2 gears of the hopper and transfer the contents of the cabin to the back of the machine in the direction of the air and grain exit triangle. If the triangular sliding valve is open, the grains will come out of the grain exit valve by contacting the high-pressure air and will be discharged at the desired location through the pipe connected to it.
✔️
The wheel, which is actually a long bladed shaft along the cabin, rotates in two bearings in the middle of the driving force from the belt and pulley, and it causes the grain and straw stored in the cabin to mix, and it works when that the lever of the same function is in the engaged position.
✔️ Fan and aerial channel system
The fan of the device causes the air flow in the channels by rotation, which in the case of air loading through the air suction channel that is connected to the air inlet channel to the ceiling channel, the air from the air suction ceiling channel after passing through the ceiling channel net It sucks from the space inside the cabin and exits through the air outlet channel and the air outlet valve, due to this function, the air pressure inside the cabin becomes negative, and the air enters the cabin through the grain suction valve along with grain or straw, and the loading operation is carried out. In the discharge operation, the air inlet valve is opened by the air inlet valve lever, and the air outlet valve is closed by the air outlet valve lever. In this case, the high-pressure air flow enters the air inlet channel in the air outlet channel and then enters the air and grain outlet triangle, and due to the fact that the triangular sliding valve is open, the high-pressure air enters the grain through The grain exit valve empties in the direction of the pipe installed to it at the desired location.
