Description
Technical Field
[0001] This invention relates to the field of grain collection technology, specifically a grain collector with adjustable screening function. Background Technology
[0002] Sun-drying grain is a crucial step in agricultural production and grain storage. Its core purpose is to remove excess moisture from the grain through sunlight, thereby ensuring grain quality, extending storage time, and reducing losses.
[0003] In modern grain collection operations, traditional grain collection equipment has many drawbacks: 1. Existing equipment can often only perform the simple function of grain collection, and it is difficult to effectively clean and process the collected grain.

[0004] 2. Different types of grains vary in size. Traditional screening equipment has a fixed structure and cannot be adjusted according to the type of grain, resulting in poor screening effect and narrow applicability.

Wave blocks are fixedly connected to the lower surface of the sieve plate. The wave blocks abut against the wave blocks. Four opposing mounting plates are fixedly connected to the inner sidewall of the secondary storage box. Guide rods are fixedly connected to the mounting plates.

[0018] This invention allows for adjustment of the sieve hole size via the relative sliding of sieve plate one and sieve plate two through an adjustment module in the sieving assembly. This adapts to the volume of different types of grains, ensuring efficient removal of attached impurities from grains of different sizes. It is suitable for various grain collection scenarios.
[0019] This invention significantly improves the separation efficiency of dust, gravel and grain by combining the lateral reciprocating movement of the secondary storage box in the screening assembly with the up-and-down vibration of the second sieve plate, thereby reducing the residue of impurities in the grain.
[0020] This invention utilizes the reciprocating vibration of an elastic ball in conjunction with the second sieve plate to cause the elastic ball to bounce above the second sieve plate, thereby altering the local vibration frequency and amplitude of the sieve plate. This makes the grain movement trajectory more disordered, reducing the probability of the sieve holes becoming clogged due to grain accumulation and decreasing the frequency of manual cleaning.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0031] In one embodiment, such as Figures 1-8 As shown, a grain collector with adjustable screening function includes a base plate 2, wheels 3, a collection component, and a screening component. The wheels 3 are located below the base plate 2. The collection component includes a bucket 1, a motor 8, and a collection roller 9. The bucket 1 is fixedly connected to the side wall of the base plate 2. A primary storage box 10 is fixedly connected to the upper surface of the base plate 2. The collection roller 9 is rotatably mounted on the upper surface of the base plate 2 through a bearing seat. The collection roller 9 is driven by the motor 8. The screening component is set on the bottom plate 2 to shake off the dust and gravel adhering to the grain.
[0032] The controller on the base plate 2 is controlled by the remote control. The controller controls the wheels 3 to move the collector. The bucket 1 scoops up the grain on the ground. The controller controls the motor 8 to start. The motor 8 drives the grain into the primary storage box 10 for initial collection.
[0033] In one embodiment, a mounting base 4 is fixedly connected to the upper surface of the base plate 2, and a lifting cylinder 5 is fixedly connected to the mounting base 4. A screw rod 7 is connected to the inner top wall of the lifting cylinder 5 through a bearing. A motor 6 is installed on the top wall of the lifting cylinder 5 to drive the screw rod 7 to rotate. A discharge pipe is provided on the side wall of the lifting cylinder 5, and the feed end of the lifting cylinder 5 is located in the primary storage box 10.
[0034] The controller starts the motor 6, which drives the screw rod 7 to rotate. The screw rod 7 lifts the grain in the primary storage box 10 and transfers it to the sieve plate 34 in the secondary storage box 11.
[0035] In one embodiment, the screening assembly includes a secondary storage box 11, a second mounting base 16, and a turntable 18. The top and bottom walls of the secondary storage box 11 are open. Four opposing support rods 23 are fixedly connected to the upper surface of the bottom plate 2. A fixing plate 24 is fixedly connected to the upper surface of the support rods 23. A guide rail 25 is fixedly connected to the upper surface of the fixing plate 24. Four opposing sliding rods 26 are fixedly connected to the side wall of the secondary storage box 11. The sliding rods 26 are slidably connected to the inner wall of the guide rail 25. A second sieve plate 34 is provided inside the secondary storage box 11. The second sieve plate 34 has a plurality of sieve holes. A dirty storage box 21 is placed on the upper surface of the bottom plate 2. The dirty storage box 21 is located below the second sieve plate 34. Mounting base 2 is fixedly connected to the upper surface of the base plate 2. Mounting base 2 is equipped with motor 3 17. The output end of motor 3 17 is fixedly connected to turntable 18. Turntable 18 is connected to connecting rod 19 through pin. The end of connecting rod 19 away from turntable 18 is connected to the side wall of secondary storage box 11 through pin.
[0036] The controller controls motor 17 to drive turntable 18 to rotate. Turntable 18 drives connecting rod 19 to move. Connecting rod 19 drives secondary storage box 11 to move back and forth along the track direction of guide rail 25, causing the grain above screen plate 34 to sway laterally. Some sand and dust are shaken off from the holes and fall into dirty storage box 21, automatically screening the collected grain to avoid too much dust and sand on the surface of the grain during collection.
[0037] The collection component quickly collects the grain from the ground into the primary storage bin, and then conveys it to the screening component via the lifting cylinder. The screening component can effectively shake off the dust and gravel attached to the grain, making the collection and screening process continuous and improving the efficiency of operation.
[0038] In one embodiment, a spring plate 27 is fixedly connected to the upper surface of the fixed plate 24, and a spring is provided between the slide rod 26 and the spring plate 27. The spring can provide a certain amount of cushioning.
[0039] In one embodiment, a vertical vibration module is provided inside the secondary storage box 11. The vertical vibration module includes a mounting plate 28 and a wave block 29. The mounting plate 28 is fixedly connected to the lower surface of the fixed plate 24 through a connecting block. Several wave blocks 29 are fixedly connected to the upper surface of the mounting plate 28. Wave blocks 30 are fixedly connected to the lower surface of the sieve plate 34. Wave blocks 30 abut against wave blocks 29. Four mounting plates 31 are fixedly connected to the inner side wall of the secondary storage box 11 in pairs. Guide rods 32 are fixedly connected to the mounting plates 31. The guide rods 32 are slidably connected to the sieve plate 34 through the plate. A spring is fixedly connected between the sieve plate 34 and the guide rods 32.
[0040] When the secondary storage box 11 causes the grain above the second sieve plate 34 to sway laterally, the wave block 29, the wave block 30, and the spring work together to make the second sieve plate 34 vibrate up and down along the direction of the guide rod 32, thereby improving the grain screening effect and accelerating the separation of dust and sand from the grain.
[0041] In one embodiment, an adjustment module is provided inside the secondary storage box 11. The adjustment module includes a sieve plate 33 and a positioning bolt 35. A sieve plate groove is opened on the side wall of the sieve plate 34. The sieve plate 33 is slidably connected to the inner side wall of the sieve plate groove. The sieve plate 33 has a plurality of sieve holes. The sieve holes of the sieve plate 33 correspond one-to-one with the sieve holes of the sieve plate 34. The sieve plate 34 and the sieve plate 33 are fixed by the positioning bolt 35.
[0042] Depending on the size of the grain being collected, the relative size of the sieve holes between sieve plate 1 33 and sieve plate 2 34 can be adjusted. To adjust, simply loosen the positioning bolt 35. Sieve plate 2 34 has a groove for sliding the positioning bolt 35. After the positioning bolt 35 is loosened, it can be manually pulled. The positioning bolt 35 causes sieve plate 1 33 to slide in the groove of sieve plate 2 34, causing the sieve holes of sieve plate 1 33 to be misaligned with the sieve holes of sieve plate 2 34. This allows for adjustment of the relative size of the holes between the two sieves, making it suitable for different sizes of grains and efficiently shaking off dust, gravel, and dirt attached to the grain. The shaken-off dust, gravel, and mud eventually fall into the dirt storage box 21 for centralized processing.
[0043] The adjustment module in the sieving assembly can adjust the size of the sieve holes by sliding the sieve plate one and sieve plate two relative to each other. It can be adapted to the size of different types of grains, ensuring that the attached impurities can be efficiently shaken off grains of different sizes. It is suitable for a variety of grain collection scenarios.
[0044] In one embodiment, a partition frame 12 is fixedly connected to the secondary storage box 11. A partition groove is provided on the inner side wall of the partition frame 12. A partition 13 is slidably connected to the inner side wall of the partition groove. A magnet 14 is embedded in the inner side wall of the partition groove. The partition 13 is made of magnetic material.
[0045] The partition 13 can be removed from the partition frame 12, allowing the grain to pass through the partition frame 12 and enter the unloading hopper 20. The magnet can hold the partition 13 in place.
[0046] In one embodiment, a discharge hopper 20 is fixedly connected to the lower surface of the secondary storage box 11, and a tertiary storage box 22 is placed on the upper surface of the base plate 2, with the tertiary storage box 22 located below the discharge hopper 20.
[0047] After screening, the grain falls from the unloading hopper 20 into the third-stage storage box 22, completing the final collection of grain.
[0048] In one embodiment, the primary storage box 10 has a trapezoidal cross-section.
[0049] The trapezoidal design helps to gather the grain below the lifting cylinder 5.
[0050] In one embodiment, an elastic ball rope is attached to the side wall of the lifting cylinder 5, and an elastic ball 15 is fixedly connected to the other end of the elastic ball rope. The elastic ball 15 is placed inside the secondary storage box 11.
[0051] The above embodiments disclose a grain collector with adjustable screening function, the specific working principle and process of which are as follows: S1: First, adjust the relative size of the sieve holes between sieve plate 1 33 and sieve plate 2 34 according to the size of the grain variety being collected. When adjusting, simply loosen the positioning bolt 35. Sieve plate 2 34 has a sliding groove for sliding the positioning bolt 35. After the positioning bolt 35 is loosened, it can be manually pulled. The positioning bolt 35 causes sieve plate 1 33 to slide in the sieve plate 1 groove of sieve plate 2 34, causing the sieve holes of sieve plate 1 33 and sieve holes of sieve plate 2 34 to be misaligned, thereby adjusting the relative size of the holes between the two sieve holes. This method is applicable to different sizes and types of grains, and can shake off dust, gravel, and dirt attached to the grains most efficiently. The shaken-off dust, gravel, and dirt eventually fall into the dirt storage box 21 for centralized treatment; S2: When it is necessary to collect grain that has been exposed to the sun on the ground, the controller on the base plate 2 can be controlled by the remote control. The controller controls the wheels 3 to drive the collector to move. The bucket 1 scoops up the grain on the ground. The controller controls the motor 8 to start. The motor 8 drives the grain into the primary storage box 10 for initial collection. S3: The controller controls the motor 6 to start, the motor 6 drives the screw rod 7 to rotate, the screw rod 7 lifts the grain in the primary storage box 10 and transfers it to the sieve plate 34 in the secondary storage box 11; S4: The controller controls motor 317 to drive turntable 18 to rotate. Turntable 18 drives connecting rod 19 to move. Connecting rod 19 drives secondary storage box 11 to move back and forth along the track direction of guide rail 25, so that the grain above screen plate 234 shakes laterally. Some sand and dust are shaken off from the holes and fall into dirty storage box 21, automatically screening the collected grain to avoid too much dust and sand on the surface of the grain when collecting it. S5: When the secondary storage box 11 causes the grain above the second sieve plate 34 to sway laterally, the first wave block 29, the second wave block 30, and the spring cooperate with each other to make the second sieve plate 34 vibrate up and down along the direction of the guide rod 32, thereby improving the screening effect of the grain and accelerating the separation of dust and sand from the grain. While the second sieve plate 34 vibrates up and down, it causes the elastic ball 15 to bounce above the second sieve plate 34. The grain originally moves back and forth in the up and down direction. Over time, some sieve holes may be blocked by the grain. The bouncing of the elastic ball 15 will slightly change the local vibration frequency and amplitude of the second sieve plate 34, making the movement trajectory of the grain on the sieve surface more disordered, avoiding continuous accumulation in the same batch of sieve holes, thereby reducing the probability of blockage.
[0052] S6: After screening, the partition 13 can be removed from the partition frame 12, allowing the grain to pass through the partition frame 12 and enter the unloading hopper 20, and then fall from the unloading hopper 20 into the third-level storage box 22 to complete the final collection of grain. After that, it is only necessary to transport the grain in the third-level storage box 22 to the storage warehouse for storage. The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
