Description

Technical Field

[0001] This utility model relates to the field of agricultural product processing technology, specifically to a crushing device for agricultural product processing. Background Technology

[0002] Many agricultural products need to be processed and crushed before they can be better used in feed processing, food processing, biomass energy processing, and other fields. Some common agricultural products include corn, wheat, and rice, which can be made into high-quality feed or food ingredients after being crushed and processed.

[0003] For example, Chinese utility model patent CN221907526U discloses a multi-stage crushing device for producing organic fertilizer from agricultural waste, including a base plate, a support arm and a support rod on the base plate, a spiral conveying structure on the support arm, a discharge pipe and a feed inlet on the spiral conveying structure, the feed inlet being connected to an external structure, and the external structure having a crushing structure, a feeding structure and a uniform material structure.

[0004] The above solution has the following shortcomings in practical use:

[0005] The scheme employs multiple mixing processes, initially crushing the materials and then further crushing them using a spiral conveyor structure. However, in actual use, due to the dispersed nature of agricultural products such as corn, wheat, and rice, the agricultural products tend to disperse outside the crushing range when being fed into the system, resulting in an unsatisfactory crushing effect. Utility Model Content

[0006] The purpose of this invention is to provide a crushing device for agricultural product processing to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a crushing device for agricultural product processing, comprising a frame and a crushing box mounted on the frame. A feeding funnel is provided at the top of the crushing box, and a discharge funnel is provided at the bottom of the crushing box. A discharge pipe is provided on the outlet side of the discharge funnel. A sieve plate is provided in the upper part of the crushing box. Two material gathering seats are provided on the upper surface of the sieve plate. Two material pushing seats are slidably connected between the two material gathering seats. A crushing seat is provided between the two material pushing seats. A driving component is provided on the crushing box, which simultaneously drives the crushing seat and the material pushing seats to move.

[0008] Preferably, the driving component includes a motor, a second connecting rod, and two first connecting rods. The second connecting rod is located between the two first connecting rods. The output shaft of the motor is connected to one of the first connecting rods. A lifting plate is rotatably connected to the second connecting rod, and the bottom end of the lifting plate is connected to the crushing seat.

[0009] Preferably, each of the two connecting rods is fitted with a drive rod, the bottom end of the drive rod is rotatably connected to a connecting seat, both sides of the connecting seat are rotatably connected to push plates via rotating shafts, and the ends of the push plates are rotatably connected to fixed blocks. The fixed blocks are respectively connected to the inner wall of the crushing box and the pusher seat.

[0010] Preferably, the crushing box is provided with a second sieve plate, which is located below the first sieve plate and is inclined. A feeding pipe is inclined on one side of the crushing box, and the inlet of the feeding pipe is close to the lowest side of the second sieve plate.

[0011] Preferably, the discharge port of the feeding pipe is equipped with a screw feeder, and the discharge port of the screw feeder is connected to the feeding funnel through a discharge pipe.

[0012] Preferably, the two material collection seats are symmetrically arranged and the cross-section of the material collection seats is a right-angled trapezoidal structure, the two material pusher seats are symmetrically arranged and the cross-section of the material pusher seats is a right-angled trapezoidal, and the two sides of the material pusher seats are in contact with the inclined surface of the material collection seats.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When crushing agricultural products, the workers feed the products to be crushed onto the upper surface of the screen plate through the feeding funnel. Then, they control the drive unit to make the crushing seat move up and down to crush the agricultural products. During this process, the drive unit also drives the pusher seat to move laterally to gather the agricultural products that have been scattered due to the impact of the crushing seat. This ensures that the agricultural products are always within the impact range of the crushing seat, avoiding the phenomenon that the scattered agricultural products cannot be crushed, and ensuring the crushing effect.

[0022] 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.

[0023] Please see Figures 1-5 This utility model provides a technical solution:

[0024] like Figure 1 and Figure 2 As shown, a crushing device for agricultural product processing includes a frame 1 and a crushing box 2 mounted on the frame 1. A feeding funnel 3 is located at the top of the crushing box 2, and a discharge funnel 4 is located at the bottom of the crushing box 2. A discharge pipe 5 is located at the outlet side of the discharge funnel 4. In actual use, a valve can be installed on the discharge pipe 5 as needed to control the discharge. A sieve plate 6 is located in the upper part of the crushing box 2. Two material gathering seats 7 are located on the upper surface of the sieve plate 6. Two pusher seats 8 are slidably connected between the two material gathering seats 7. A crushing seat 9 is located between the two pusher seats 8. A driving component is provided on the crushing box 2 to simultaneously drive the crushing seat 9 and the pusher seats 8. The crushing seat 9 reciprocates up and down to crush the agricultural products, while the pusher seats 8 reciprocate laterally to gather the agricultural products scattered by the impact of the crushing seat 9. This ensures that the agricultural products remain within the impact range of the crushing seat 9, preventing the inability to crush scattered agricultural products and ensuring the crushing effect.

[0025] Furthermore, the two material collection seats 7 are symmetrically arranged and the cross-section of the material collection seat 7 is a right-angled trapezoidal structure, the two material pusher seats 8 are symmetrically arranged and the cross-section of the material pusher seat 8 is a right-angled trapezoidal, and the two sides of the material pusher seat 8 are in contact with the inclined surface of the material collection seat 7.

[0026] like Figure 3As shown, the driving component includes a motor 10, a second connecting rod 12, and two first connecting rods 11. The second connecting rod 12 is located between the two first connecting rods 11. The output shaft of the motor 10 is connected to one of the first connecting rods 11. A lifting plate 13 is rotatably connected to the second connecting rod 12, and the bottom end of the lifting plate 13 is connected to the crushing seat 9. Both the second connecting rod 12 and the first connecting rod 11 have a U-shaped structure, and the protruding parts of the second connecting rod 12 and the first connecting rod 11 face opposite directions. This allows the distance between the two pushing seats 8 to be maximized when crushing agricultural products. When the crushing seat 9 is raised to its highest point... The distance between the two pusher seats 8 is minimized, enabling the aggregation of agricultural products. When crushing agricultural products, the motor 10 is controlled to start the rotation of the second connecting rod 12 and the two first connecting rods 11. The second connecting rod 12 drives the lifting plate 13 to move up and down reciprocally, thereby realizing the up and down reciprocating motion of the crushing seat 9. It should be noted that the lifting plate 13 and the crushing seat 9 can be fixedly connected or rotatably connected. When the lifting plate 13 and the crushing seat 9 are fixedly connected, the crushing seat 9 can swing with the lifting plate 13 to a certain extent, thereby improving the crushing effect.

[0027] Furthermore, such as Figure 5 As shown, each of the connecting rods 12 is fitted with a drive rod 14. The bottom end of the drive rod 14 is rotatably connected to a connecting seat 15. Both sides of the connecting seat 15 are rotatably connected to push plates 16 via rotating shafts. The ends of the push plates 16 are rotatably connected to fixed blocks 17. The fixed blocks 17 are respectively connected to the inner wall of the crushing box 2 and the pusher seat 8. When crushing agricultural products, as the connecting rod 12 rotates, the drive rod 14 pulls the connecting seat 15 to move up and down reciprocally. Then, under the transmission of the push plates 16, the pusher seat 8 moves reciprocally. During this process, as the connecting seat 15 moves, the drive rod 14 can generate displacement on the connecting rod 12. It should be noted that in this embodiment, the end of the drive rod 14 is provided with a ball head, and the connecting seat 15 is provided with a groove corresponding to the ball head.

[0028] like Figure 4As shown, a second sieve plate 18 is installed inside the crushing box 2. The second sieve plate 18 is located below the first sieve plate 6 and is inclined. A feeding pipe 19 is inclined on one side of the crushing box 2. The inlet of the feeding pipe 19 is close to the lowest side of the second sieve plate 18. A screw conveyor 20 is installed at the outlet of the feeding pipe 19. The outlet of the screw conveyor 20 is connected to the feeding funnel 3 through the discharge pipe 21. The sieve holes of the second sieve plate 18 are smaller than those of the first sieve plate 6. Under the action of the second sieve plate 18 and the first sieve plate 6, the agricultural product powder can be crushed. Secondary screening ensures the crushing effect. When the initially crushed agricultural products fall onto the second screen plate 18, they are displaced under the guidance of the inclined surface of the second screen plate 18. During this process, smaller agricultural products that meet the requirements pass through the screen holes and fall into the feeding funnel 4, while larger particles enter the screw conveyor 20 through the feeding pipe 19 for further crushing. At this time, these agricultural products will mix with the agricultural products on the first screen plate 6 and will not fall onto the second screen plate 18, or only a small amount will fall onto the second screen plate 18. The crushing seat 9 then performs a second crushing operation on the agricultural products.

[0029] The workflow of this embodiment is as follows: When the worker is crushing agricultural products, the agricultural products to be crushed are fed onto the upper surface of the screen plate 6 through the feeding funnel 3. Then, the driving component is controlled to make the crushing seat 9 move up and down to crush the agricultural products. When the crushed agricultural products fall onto the screen plate 18, they are displaced under the guidance of the inclined surface of the screen plate 18. During this process, the smaller agricultural products that meet the requirements pass through the screen holes and fall into the feeding funnel 4.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
