Description

Technical Field

[0001] The invention relates to the field of machinery, in particular to an agricultural machinery structure, and specifically to a grain thrower which is convenient for taking grain. Background Art

[0002] my country is a big agricultural country and attaches great importance to grain harvesting and storage. The grain harvesting process includes harvesting, chaff removal and storage. Before storage, the grain needs to be screened to remove chaff and stones.

[0003] At present, grain throwing machines are used to screen grain. This machine is not limited by the external environment and can screen chaff and stones without wind power, and has been widely promoted. This machine also has certain defects, because the grain is driven by the pits on the belt and tilted and thrown up. The chaff falls closest and the stones fall farthest. However, grain or stones often get stuck in the small pits, and the small pits with grain or stones stuck are unusable. If there are too many stuck, the efficiency of grain throwing is seriously affected. In addition, the existing grain throwing machines throw grain on the ground, which needs to be separated manually and collected slowly, which is very troublesome. Summary of the invention

[0004] The object of the present invention is to provide a grain thrower that is convenient for taking grain, so as to solve the defects of the existing grain throwers that are convenient for taking grain, such as being prone to getting stuck and resulting in low grain throwing efficiency, and solving the defect of slow grain collection.

[0005] To achieve the above-mentioned purpose, the technical solution of the present invention is a grain throwing machine that is convenient for taking grain, including a frame, a conveyor belt, a grain deducting mechanism, a grain storage box and a grain pressing wheel. The conveyor belt, the grain storage box and the grain pressing wheel are all installed on the frame. The conveyor belt includes a first roller, a second roller and a belt. The first roller and the second roller are both installed on the frame, and the position of the first roller is lower than the second roller. The first roller is driven to rotate by a motor, and the belt wraps the first roller and the second roller. A grain placement pit is provided on the surface of the belt. The upper part of the belt is transmitted from the first roller to the second roller. The grain storage box and the grain pressing wheel are both located above the first roller, and the lower ends of the grain storage box and the grain pressing wheel are both connected to the belt The grain storage box and the grain pressing wheel are in close contact with each other, and the lower ends of the grain storage box and the grain pressing wheel are horizontally parallel. The upper part of the belt is compressed and divided into a parallel section and an inclined section. The grain storage box and the grain pressing wheel are arranged in sequence along the conveying direction of the belt. The lower end face of the grain storage box is hollow. A grain outlet is arranged below one end of the grain storage box close to the grain pressing wheel. The grain retaining mechanism includes a grain brush and a partition. The shelf is arranged vertically and perpendicular to the conveying direction of the belt. The shelf divides the grain storage box into a grain storage space and a grain retaining space. The grain storage space is connected to the grain outlet. The grain brush is installed in the grain retaining space. A material trough is arranged in the conveying direction of the conveying belt. A plurality of material barrels are arranged in the material trough, and the arrangement direction of the material barrels is parallel to the conveying direction of the conveying belt.

[0006] The angle of the inclined section is 45°.

[0007] The grain storage box is provided with a box door.

[0008] Two symmetrical first slots are arranged on the inner wall of the grain storage box, and the two ends of the partition are respectively embedded in the two first slots. The first slots are also hinged with first locking buckles.

[0009] Two symmetrical second slots are arranged on the inner wall of the grain storage box, and the two ends of the grain brush are respectively embedded in the two second slots. The second slots are also hinged with second locking buckles.

[0010] The present invention has the following advantages:

[0011] (1) The grain storage box is divided into two parts by a partition. A brush is set in the small space in the front to brush away the grain or stones stuck in the grain pit first, and the brushed grain is placed in the grain deduction space. After the grain is thrown, the grain is taken out from the grain deduction space to speed up the grain throwing efficiency;

[0012] (2) The partition and grain brush can be pulled out, and then the grain in the grain-retaining space can be swept into the grain-storing space, which is very convenient for cleaning the ration space;

[0013] (3) The grain storage box is equipped with a door to prevent grain from splashing when the grain is brushed out, thereby avoiding grain waste;

[0014] (4) A material trough and multiple material barrels are set up. The material trough contains a large amount of stones and bran, which can be processed later, and the clean grain basically falls into the material barrel. The staff only needs to take away the material barrel, which is very convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0021] Example 1

[0022] like Figure 1 , Figure 2 As shown, a grain throwing machine for convenient grain taking includes a frame 1, a conveyor belt 2, a grain deducting mechanism 3, a grain storage box 4 and a grain pressing wheel 5. The conveyor belt 2, the grain storage box 4 and the grain pressing wheel 5 are all installed on the frame 1. The conveyor belt 2 includes a first roller 201, a second roller 202 and a belt 203. The first roller 201 and the second roller 202 are both installed on the frame 1, and the position of the first roller 201 is lower than the second roller 202. The first roller 201 is driven to rotate by a motor 7, and the belt 203 wraps the first roller 201 and the second roller 202. A grain placement pit 204 is provided on the surface of the belt 203. The upper part of the belt 203 is transmitted from the first roller 201 to the second roller 202. The grain storage box 4 and the grain pressing wheel 5 are both located above the first roller 201, and the lower ends of the grain storage box 4 and the grain pressing wheel 5 are in contact with the belt 203. The lower ends of the box 4 and the grain pressing wheel 5 are horizontally parallel, and the upper part of the belt 203 is compressed into a parallel section 205 and an inclined section 206. The grain storage box 4 and the grain pressing wheel 5 are arranged in sequence along the conveying direction of the belt 203. The lower end face of the grain storage box 4 is hollow. A grain outlet 401 is arranged below one end of the grain storage box 4 close to the grain pressing wheel 5. The grain retaining mechanism 3 includes a grain brush 301 and a partition 302. The shelf 302 is vertically and perpendicular to the conveying direction of the belt 203. The shelf 302 divides the grain storage box 4 into a grain storage space 402 and a grain retaining space 403. The grain storage space 402 is connected to the grain outlet 401. The grain brush 301 is installed in the grain retaining space 403. A material trough 6 is arranged in the conveying direction of the conveying belt 2. A plurality of material barrels 601 are arranged in the material trough 6. The arrangement direction of the material barrels 601 is parallel to the conveying direction of the conveying belt 2.

[0023] The working principle of the device is as follows: the staff puts the grain into the grain storage space 402, starts the motor 7, the motor 7 drives the first roller 201 to rotate, the second roller 202 is the driven roller, under the cooperation of the first roller 201 and the second roller 202, the belt 203 is driven to transmit, the upper part of the belt 203 is compressed at the grain pressing wheel 5, forming a parallel section 205 and an inclined section 206, the grain storage box 4 and the grain pressing wheel 5 are placed on the parallel section 205, the grain is taken out from the grain outlet 401 by the belt 203, and then the grain is taken out by the belt 203. When the grain wheel 5 is over-pressed, the grains in the grain pit 204 can be retained, while those not in the grain pit 204 are blocked by the grain wheel 5. The inclined section 206 drives the grains to rise, and finally the grains are thrown out at the second roller 202. If there is no grain pit 204, the force of the grains being thrown by the belt 203 is the friction between the grains and the belt 203. This force is very small and cannot be thrown too far. By using the grain pit 204, a thrust is given to the grains, so the grains can be thrown out 6-8 meters, and the screening effect is very good.

[0024] The grain pit 204 is set up so that the grain can be thrown farther, but the grain pit 204 is small, and it is very easy for grain or stones to get stuck in the grain pit 204, making the grain pit 204 unusable, which reduces the grain throwing efficiency of the entire device. The grain holding mechanism 3 is installed, and the partition 302 divides the grain storage box 4. The grain storage space 402 performs the original function of the grain storage box 4. The grain brush 301 set in the grain holding space 403 can brush out the grain or stones stuck in the grain pit 204, and the grain and stones are left in the grain holding space 403. After the grain throwing is completed, they are taken out from the grain holding space 403. The grain brush 301 adopts an ordinary bristle brush, which is set perpendicular to the belt 203, and can easily output grain or stones.

[0025] The material barrel 601 is placed in the material trough 6. The material barrel 601 is mainly placed within 3-5m from the conveyor belt 2. It can be placed starting from 3m. The material barrels 601 are placed adjacent to each other. It is best to place 3 material barrels 601 within 3-5m. In this way, most of the grain falls into the material barrel 601. The staff only needs to take away the material barrel 601 to complete the grain collection work, saving a lot of time.

[0026] The angle of the inclined section 206 is 45°. At this angle, the grain is thrown farther and the screening effect is good.

[0027] Example 2

[0028] like Figure 3 In this embodiment, based on the first embodiment, a box door 404 is provided on the grain storage box 4.

[0029] When the grain brush 301 brushes out grain or stones, the grain or stones may splash. The box door 404 is provided to prevent the grain from flying out of the grain storage box 4, thereby avoiding the waste of grain.

[0030] Example 3

[0031] like Figure 4 , Figure 5 In this embodiment, based on the first embodiment, two symmetrical first slots 405 are provided on the inner wall of the grain storage box 4, and the two ends of the partition 302 are respectively embedded in the two first slots 405, and the first slots 405 are also hinged with first locking buckles 406.

[0032] Two symmetrical second slots 407 are arranged on the inner wall of the grain storage box 4 , and the two ends of the grain brush 301 are respectively embedded in the two second slots 407 . A second locking buckle 408 is also hinged on the second slot 407 .

[0033] The staff can take out the grain brush 301 and the partition 302, and then sweep the grain in the grain holding space 403 into the grain placing space 402, which is very convenient. When in use, the first locking buckle 406 and the second locking buckle 408 are locked to lock the grain brush 301 and the partition 203. The first locking buckle 406 is locked with the first card slot 405 by screws, and the second locking buckle 408 is also locked with the second card slot 407 by screws.

[0034] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
