Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable screening technology, specifically to a discharge structure for a fruit and vegetable screening machine. Background Technology

[0002] Currently, the discharge structures of fruit and vegetable sorting machines on the market generally have certain defects. In common discharge designs, fruits and vegetables, after undergoing a rigorous sorting process, fall freely directly from the discharge port. This simple and direct discharge method makes the fruits and vegetables highly susceptible to damage such as abrasions, flesh breakage, and fruit cracking due to high-speed collisions with the receiving surface during the fall. This problem is particularly prominent for fruits and vegetables with delicate skins and soft textures, such as strawberries, grapes, peaches, and tomatoes.

[0003] From a practical production perspective, this discharge structure leads to a high fruit and vegetable loss rate. In large-scale fruit and vegetable sorting operations, the economic losses caused by discharge collisions are significant. Furthermore, damaged fruits and vegetables are unlikely to meet the standards for high-quality products, negatively impacting the company's product reputation and economic benefits. Moreover, existing discharge structures often fail to adequately consider the differences in characteristics among various types of fruits and vegetables, lacking targeted buffering and protective measures, making this problem widespread in various fruit and vegetable sorting processes. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a discharge structure for a fruit and vegetable sorting machine, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a discharge structure for a fruit and vegetable screening machine, comprising a base plate, at least two guide frames, and a horizontal plate;

[0006] At least two of the guide frames are mounted on the base plate, and adjacent guide frames are fitted together. The front section of one of the guide frames is open, and the left and right sides of the inner wall of one of the guide frames are bent in opposite directions to form a figure-eight-shaped guide opening. The horizontal plate is mounted on at least two guide frames.

[0007] Corresponding to at least two of the guide frames, at least two buffer components are provided on the base plate;

[0008] One of the buffer components includes two first connecting plates, both of which are mounted on the upper surface of the base plate and are located on the left and right sides of one of the guide frames respectively. The front sides of both first connecting plates are hinged to second connecting plates via hinge shafts, and a U-shaped rod is fixedly mounted on the two second connecting plates.

[0009] A bearing plate is provided on the outside of the U-shaped rod, and a buffer pad is installed on the bearing plate;

[0010] A support plate is installed on the front side of the base plate, and the second connecting plate is attached to the support plate.

[0011] Furthermore, the cushioning pad is detachably mounted on the support plate using double-sided adhesive tape.

[0012] Furthermore, the cushioning pad is made of polyethylene.

[0013] Furthermore, the support plate is located below the opening of the guide frame.

[0014] Furthermore, it also includes at least two cover plates hinged to the front side of the horizontal plate via a hinge shaft, wherein two return springs are installed on the side of one of the cover plates facing the guide frame, and the ends of the two return springs away from the cover plate are connected to the bottom plate.

[0015] Corresponding to the cover plate, an upper top structure is provided on the opposite side of each of the two second connecting plates.

[0016] Furthermore, one of the top structures includes a support rod installed on opposite sides of the two second connecting plates, the top end of which is integrally formed with an arc-shaped rod, which fits against the side of the cover plate facing the guide frame.

[0017] Furthermore, the support rod is integrally formed in an L-shape.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0019] The discharge structure of this fruit and vegetable sorting machine uses the elastic cushioning of the polyethylene buffer pad and the stable support of the bearing plate to avoid the rigid collision of fruits and vegetables falling directly. It is especially effective in protecting fragile fruits and vegetables, reducing production losses. The linkage design of the cover plate and the return spring can quickly close the guide port when changing the loading frame to prevent fruits and vegetables from falling in an disorderly manner. At the same time, multiple guide frames can realize classified discharge and improve the efficiency of subsequent processing. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-3 The discharge structure of the fruit and vegetable sorting machine in this embodiment solves the problem of damage to fruits and vegetables due to direct falling in the traditional discharge structure. It can be adapted to various discharge scenarios after sorting of fragile and conventional fruits and vegetables.

[0026] Specifically, the structure mainly consists of a base plate 1, at least two guide frames 2, a horizontal plate 3, at least two buffer components 4, and at least two cover plates 406. At least two guide frames 2 are fixed side by side on the upper surface of the base plate 1, with adjacent sides tightly fitted together. The front section of the guide frame 2 is designed to be open, and its inner walls are bent inward on both the left and right sides to form a figure-eight-shaped guide opening, which can guide the screened fruits and vegetables to the opening. The horizontal plate 3 is installed horizontally at the top and rear end of the two guide frames 2, serving to connect and fix the guide frames 2.

[0027] In detail, one of the buffer components 4 includes two first connecting plates 401. Taking the left buffer component 4 as an example, it includes two first connecting plates 401, two second connecting plates 402, a U-shaped rod 403, a bearing plate 404, and a buffer pad 405.

[0028] Two first connecting plates 401 are welded to the base plate 1 and are located on the left and right sides of the left guide frame 2, respectively. The second connecting plate 402 is connected to the front side of the first connecting plate 401 through a hinge shaft and can rotate flexibly around the hinge shaft. The two ends of the U-shaped rod 403 are fixed perpendicularly to the middle of the two second connecting plates 402, respectively. The bearing plate 404 is sleeved on the outside of the U-shaped rod 403 and is located directly below the opening of the guide frame 2. A polyethylene buffer pad 405 is attached to the upper surface of the bearing plate 404 with double-sided tape.

[0029] In actual setup, in the buffer assembly 4, the first connecting plate 401 is fixed to the base plate 1, and the hinge shaft provides a rotation fulcrum for the second connecting plate 402, so that the position of the bearing plate 404 can be adjusted by the U-shaped rod 403. The polyethylene buffer pad 405 absorbs the impact force of falling fruits and vegetables with its own elasticity, and the detachable design makes it easy to replace according to the characteristics of fruits and vegetables. At the same time, the polyethylene material is wear-resistant and corrosion-resistant, extending its service life. The bearing plate 404 does not swing back and forth, but only adjusts its position by rotation, ensuring stable support of fruits and vegetables.

[0030] More specifically, at least two cover plates 406 are hinged to the front side of the horizontal plate 3 via hinge shafts, corresponding to the openings of at least two guide frames 2 respectively. Two return springs 407 are installed on the side of the cover plate 406 facing the guide frame 2. The other end of the return spring 407 is fixedly connected to the bottom plate 1. On the opposite side of the two second connecting plates 402, an L-shaped support rod 408 is installed. The top of the support rod 408 is integrally formed with an arc rod 409. The arc rod 409 is tightly fitted to the side of the cover plate 406 facing the guide frame 2, forming an upper top structure.

[0031] In actual setup, the cover plate 406 is hinged to the horizontal plate 3, forming a closed control structure with the return spring 407. Under normal conditions, the return spring 407 pulls the cover plate 406 to fit against the front of the guide frame 2, preventing fruits and vegetables from falling prematurely. When the second connecting plate 402 rotates, it drives the support rod 408 and the arc rod 409 to lift the cover plate 406, and the spring stretches to form a discharge port, ensuring orderly output of fruits and vegetables. The integrated design of the L-shaped support rod 408 and the arc rod 409 can accurately transmit the rotational force of the second connecting plate 402, ensuring that the opening angle of the cover plate 406 is adapted to the discharge requirements.

[0032] Furthermore, a support plate 410 is installed on the front side of the base plate 1, and the second connecting plate 402 is attached to the support plate 410. In actual installation, the support plate 410 on the front side is attached to the second connecting plate 402, which can limit the excessive rotation of the second connecting plate 402 and ensure that the bearing plate 404 is stably positioned below the opening of the guide frame 2 after unfolding, avoiding the fruit and vegetable receiving shift due to shaking.

[0033] The working principle of the above embodiments is as follows:

[0034] After the screening machine sorts fruits and vegetables of different sizes, they are fed into the corresponding guide frames 2. The U-shaped rod 403 is rotated so that the support plate 404 unfolds to the opening of the guide frame 2. At this time, the second connecting plate 402 is attached to the support plate 410, and the support plate 404 remains stable. At the same time, when the support plate 404 rotates with the U-shaped rod 403, it drives the second connecting plate 402 to rotate, so that the support rod 408 and the arc rod 409 rotate synchronously and lift the cover plate 406. The reset spring 407 is stretched, and the cover plate 406 separates from the front of the guide frame 2 to form a discharge port. The fruits and vegetables in the guide frame 2 are guided by the figure-eight guide port and fall from the opening onto the buffer pad 405 of the support plate 404. The polyethylene buffer pad 405 directly buffers the impact force and avoids damage to the fruits and vegetables.

[0035] When the loading frame needs to be replaced, rotate the bearing plate 404 upwards. The second connecting plate 402 drives the support rod 408 and the arc rod 409 to disengage from the cover plate 406. The return spring 407 rebounds and pulls the cover plate 406 to close with the front side of the guide frame 2, preventing the fruits and vegetables from falling continuously. After the replacement is completed, rotate the bearing plate 404 in the opposite direction to restore the discharge.
