Description

Technical Field

[0001] This application relates to the technical field of corn harvester equipment, and more specifically to a grain storage box that facilitates adjustment of the unloading angle. Background Technology

[0002] In the process of modernizing agriculture, corn, as an important food crop and industrial raw material, requires high efficiency and quality in its harvesting process. Corn harvesters, as the core equipment for mechanizing corn harvesting, can complete multiple tasks such as ear picking, husking, and threshing in one operation, greatly improving harvesting efficiency and reducing manual labor intensity. The grain storage bin, as a key component of the corn harvester, undertakes the important task of storing corn kernels, and its performance directly affects the continuity and efficiency of the entire harvesting operation.

[0003] However, existing grain storage bins have several problems that urgently need to be addressed. Firstly, the unloading angle is fixed, making it impossible to flexibly adjust to storage equipment of different heights and positions. In actual operation, the specifications and locations of storage equipment vary widely, and the fixed unloading angle makes it difficult for grain storage bins to adapt, greatly limiting the equipment's versatility and scope of use, and affecting the flexibility and efficiency of harvesting operations. Secondly, the grain residue rate is high. The inner walls of fixed storage bins often have a flat or right-angled structure, making it easy for grains to accumulate in corners and at the bottom. This results in a large amount of residue after unloading, causing not only grain waste but also significant cleaning difficulties. Especially in humid environments, residual grains are prone to mold, affecting subsequent use and grain quality, and may also corrode the storage bin, shortening the equipment's lifespan. Thirdly, unloading efficiency is low. Traditional unloading ports are simple in design, often with fixed openings. During unloading, grain flow is impeded, easily leading to blockages, severely affecting unloading speed and efficiency, increasing operating time and costs, and reducing the overall economic benefits of corn harvesting. Therefore, developing a grain storage box that can solve the above problems is of great practical significance. Utility Model Content

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] To achieve flexible adjustment of the unloading angle of the grain storage box, improve unloading efficiency, and reduce grain residue, this application provides an innovatively designed grain storage box with an easily adjustable unloading angle. The following will describe this design in conjunction with the attached diagram. Figure 1 -Appendix Figure 6 Its specific structure and significant technical effects are described in detail.

[0024] Reference Appendix Figure 1 -Appendix Figure 6 The storage box has an overall structure including a box body 1. The upper end of the box body 1 is provided with a feed inlet 2 for receiving the corn harvester and the kernels that have been screened by a vibrating screen, conveyed by a kernel horizontal conveying component 29 and a lifting screw component 30. The bottom side wall of the box body 1 is provided with a discharge outlet 3 for unloading the stored kernels.

[0025] Regarding the adjustment of the unloading angle, the rear wall of the box 1 is equipped with an upper rotating part and a lower rotating part. The upper rotating part is rotatably connected to the storage box rotating support frame 23 via a hanging pipe 22, and is rotatably connected to the vibrating screen frame 9; the lower rotating part is a cylinder base plate 21 welded to the rear wall of the box 1, and the output rod of the adjusting cylinder 8 is rotatably connected to the cylinder base plate 21; a cylinder seat 20 is welded to the vibrating screen frame 9, and the cylinder barrel of the adjusting cylinder 8 is rotatably connected to the cylinder seat 20. This design allows the adjusting cylinder 8 to flexibly push the box 1 to rotate around the upper rotating part, achieving precise adjustment of the unloading angle. In practical applications, the box 1 can be positioned at a suitable unloading angle by controlling the extension and retraction of the adjusting cylinder 8, according to the storage equipment of different heights and positions. This greatly improves the adaptability of the equipment, solves the problem of the fixed unloading angle of traditional grain storage boxes and the difficulty in adapting to various grain storage equipment, and effectively improves the flexibility and efficiency of unloading operations.

[0026] A material outlet adjustment mechanism is installed at the discharge port 3. This mechanism includes a sliding connecting seat 4, a baffle plate 5, a lifting shaft 6, a rotating arm 7, and a connecting plate 10. The sliding connecting seat 4 is a U-shaped connecting plate, which is set at the discharge port 3. Its lower end forms a limiting structure for limiting the bottom of the baffle plate 5, ensuring the stability of the baffle plate 5 during sliding. The baffle plate 5 is vertically slidably set on the sliding connecting seat 4, and the size of the discharge port 3 is adjusted by moving it up and down. The lifting shaft 6 is rotatably set on the front wall of the housing 1 through the ear plate, and two rotating arms 7 are installed on the lifting shaft 6. Two connecting plates 10 are rotatably set on the outer end face of the baffle plate 5. The end of the rotating arm 7 away from the lifting shaft 6 is rotatably connected to the connecting plate 10.

[0027] Furthermore, a handle 25 is provided on one side of the lifting shaft 6. An adjusting plate 26 is rotatably provided on the side of the handle 25 via a pin. The adjusting plate 26 has an adjusting groove 27, and several locking slots 28 are provided at the upper end of the adjusting groove 27. A locking shaft 24 located in the adjusting groove 27 is provided on the side wall of the box body 1. When it is necessary to adjust the discharge port 3, pull the handle 25 by hand and lift the adjusting plate 26 upward, so that the locking shaft 24 disengages from the lowest locking slot 28. Continue to pull the handle 25 by hand. At this time, the adjusting groove 27 on the adjusting plate 26 moves downward along the locking shaft 24. When the locking slot 28 at the upper end of the adjusting groove 27 moves to the corresponding position of the locking shaft 24, press the adjusting plate 26, and the locking slot 28 engages with the locking shaft 24 at the corresponding limit position, thereby limiting the position of the entire handle 25. During the rotation of the handle 25, the lifting shaft 6 is driven to rotate, which in turn drives the rotating arm 7 to rotate. The connection point between the rotating arm 7 and the connecting plate 10 moves upward. Since the sliding connecting seat 4 has a limiting and guiding effect on the baffle plate 5, the entire baffle plate 5 is lifted and moved up and down. By locking the shaft 24 into the slots 28 at different limiting positions, the size of the discharge port 3 can be precisely adjusted to meet the needs of different unloading flow rates and speeds. This effectively solves the problem of poor grain flow and easy blockage caused by the simple design and fixed opening of traditional unloading ports, thus improving unloading efficiency.

[0028] A tipping bucket 15 is rotatably mounted on the bottom of the inner wall of the box 1. The tipping bucket 15 includes a guide plate 15a and side plates 15b integrally connected to both sides of the guide plate 15a. The guide plate 15a is rotatably connected to the lower end of the box 1 via a hinge 16. Springs 18 are mounted on both sides of the guide inclined wall 14 via mounting posts 17. The end of the spring 18 away from the mounting post 17 is connected to the connecting seat on the side of the guide plate 15a. The tipping bucket 15 forms a rotational hinge with the box 1 via the hinge 16, and a lever arm is formed by the tension of the spring 18. When the tipping bucket 15 is closed, the tension of the spring 18 can effectively restrict the movement of the tipping bucket 15, reducing the possibility of the tipping bucket 15 accidentally opening due to equipment vibration or other reasons during storage, and reducing the risk of grain leakage. When the tipping bucket 15 is overturned by external force, reaching a certain angle, the tipping bucket 15 can be quickly opened through the "dead point" position of the spring 18, forming a fast discharge angle with the discharge port 3 of the box 1, further improving the unloading efficiency. In addition, the rear end of the side plate 15b is provided with an extension plate 15c extending toward one side of the box body 1. The lower end of the sliding connecting seat 4 has a limiting part 19 extending outward along both sides to limit the forward rotation of the extension plate 15c. This design further enhances the stability of the tipping bucket 15 in the closed state, while limiting the flipping angle of the tipping bucket 15 to a certain extent, ensuring that the unloading process is smooth and orderly.

[0029] The box 1 is provided with a guide wall 14 on one side relative to the discharge port 3. The design of the guide wall 14 allows the grains to flow more smoothly towards the discharge port 3 inside the box 1, reducing the accumulation of grains in the corners and bottom of the box 1, reducing the grain residue rate, avoiding waste caused by residual grains and the problem of easy mold growth in humid environments affecting subsequent use.

[0030] An observation port 11 is provided on the top of the side wall of the container 1. Operators can observe the storage status of the grains in the container 1 in real time through the observation port 11, keep track of the remaining amount, and make it easier to arrange the unloading time, thereby improving the convenience of operation and management efficiency.

[0031] A pressure sensor 13 is installed on the upper end of the inner rear wall of the box 1 via a grain-filled bracket 12. When the grain storage in the box 1 reaches a certain level and generates sufficient pressure on the pressure sensor 13, the pressure sensor 13 will send a signal to remind the operator that the box 1 is full, thus avoiding equipment damage or grain overflow due to over-storage and ensuring the normal operation of the equipment and operational safety.

[0032] The working principle of this storage box is as follows: Corn kernels harvested by the corn harvester are screened by a vibrating screen and fall into the horizontal kernel conveying assembly 29. From there, they enter the lifting screw assembly 30 and fall into the feed inlet 2 of the box body 1 for storage. When unloading is required, the box body 1 rotates around the rotating part to a suitable unloading angle by controlling the extension and retraction of the adjusting cylinder 8 according to the height and position of the storage equipment. Then, the position of the baffle plate 5 is adjusted by operating the handle 25 and the adjusting plate 26, thereby controlling the size of the discharge port 3. During unloading, the tipping bucket 15 gradually opens under the action of the spring 18 as the kernels flow out, forming a smooth discharge channel with the discharge port 3, achieving fast and efficient unloading. Simultaneously, the operator can monitor the situation inside the box body 1 in real time through the observation port 11 and the pressure sensor 13, ensuring the entire operation is safe and orderly.

[0033] In summary, the grain storage box with adjustable unloading angle proposed in this application effectively solves many problems existing in the prior art through its innovative structural design. It has achieved significant technical effects in terms of unloading angle adjustment, unloading efficiency improvement, grain residue reduction, and operational convenience and safety, and has high practical value and promotion significance.
