Description

Technical Field

[0001] This application relates to the field of agricultural production technology, specifically a separation device for agricultural production. Background Technology

[0002] Agricultural product sorting and processing is an indispensable part of the agricultural production chain. Through separation operations, agricultural products can be classified and processed according to factors such as quality, size, and maturity, ensuring product uniformity and high quality.

[0003] A search revealed that patent CN216395485U discloses a separation device for agricultural product production, specifically related to the agricultural product field. The device includes a shell, a sealing plate on the top of the shell, a feed inlet on the top surface of the sealing plate, and the sealing plate in contact with the shell. A fixing rod is located on one side of the shell, with its bottom fixedly connected to the shell and its top movably connected to the sealing plate. This invention, by incorporating a processing plate and a connecting plate, allows the circular rod and guide plate to move upwards simultaneously through the upward movement of the connecting plate. This pushes the agricultural product in the interception hole upwards, making the product more prominent and allowing for the rapid and complete removal of all structures in contact with the product, facilitating separation of the product from the relevant structures. Furthermore, the movement of the cleaning plate cleans the inner wall of the shell, preventing any residual agricultural product inside and facilitating subsequent use.

[0004] While the above-mentioned solution can clean the screening and separation device, it is difficult to screen and separate different types of agricultural products to different degrees (i.e., different degrees of coarseness in screening). Improper screening and separation may lead to some high-quality agricultural products being misjudged as substandard products and eliminated. At the same time, it may also lead to substandard or unqualified products entering the subsequent processing stage, reducing the accuracy of screening and separation. Utility Model Content

[0005] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and to propose a separation device for agricultural production to solve the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides a separation device for agricultural product production, including a device frame, a frame shaft fixedly passing through the top of the device frame, a separation cylinder rotatably connected to the outer surface of the frame shaft, a feeding hopper fixedly connected to the top of the separation cylinder, a discharge hopper fixedly connected to one end of the separation cylinder, a rotating shaft rotatably connected to the inner surface of the separation cylinder, a plurality of material-pulling plates provided on the outer surface of the rotating shaft, a crank handle fixedly connected to the end of the rotating shaft away from the discharge hopper, a detachable screening and separation mechanism provided on the lower surface of the separation cylinder, and a receiving tray detachably installed on the device frame by a fastening mechanism.

[0007] Preferably, the detachable screening and separation mechanism includes a screen frame that is detachably installed on the lower surface of the separation cylinder. A screening screen is provided on the inner side of the screen frame, and positioning holes are provided on the screen frame. The detachable screening and separation mechanism allows for the replacement and installation of screening screens with different mesh densities to meet the screening and separation needs of different agricultural products.

[0008] Preferably, a positioning rod is slidably connected to the inner surface of the separating cylinder, a collar is fixedly sleeved on the outer surface of the positioning rod, and a spring is movably sleeved on the outer surface of the positioning rod.

[0009] Preferably, the fastening mechanism includes a chuck fixedly connected to the bottom of the receiving tray, and the chuck is made of rubber. The fastening mechanism allows the receiving tray to be easily installed below the screening screen or removed so that it can be removed and bagged after the screened material is successfully received.

[0010] Preferably, the device frame is provided with a sliding groove and a V-shaped slot, and the sliding groove and the V-shaped slot are on the same horizontal plane.

[0011] Preferably, the bottom of the device frame is threaded with a screw, and the top of the screw is provided with a clamping plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This separation device for agricultural production allows for the replacement of screening screens via a detachable screening and separation mechanism, greatly improving the accuracy and flexibility of screening and separation. For different types and qualities of agricultural products, operators can select screening screens with appropriate mesh density according to actual needs.

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-4 A separation device for agricultural production includes a frame 1, a frame shaft 2 fixedly inserted at the top of the frame 1, a separation cylinder 3 rotatably connected to the outer surface of the frame shaft 2, the end of the separation cylinder 3 near the discharge hopper 5 can rotate along the frame shaft 2 to pour out the material remaining in the separation cylinder 3 after screening, a feeding hopper 4 fixedly connected to the top of the separation cylinder 3, a discharge hopper 5 fixedly connected to one end of the separation cylinder 3, a rotating shaft 6 rotatably connected to the inner surface of the separation cylinder 3, a number of sets of material-pulling plates 7 provided on the outer surface of the rotating shaft 6, a crank handle 8 fixedly connected to the end of the rotating shaft 6 away from the discharge hopper 5, a detachable screening and separation mechanism provided on the lower surface of the separation cylinder 3, and a receiving tray 17 detachably installed on the frame 1 by a fastening mechanism.

[0022] Through the above technical solution, during the screening and separation of agricultural products, the agricultural products can be put into the separation cylinder 3, and then the crank handle 8 is turned to drive the rotating shaft 6 to rotate. The material is stirred by the material-pulling plate 7, so that the material is screened and separated at the screening screen 10. The screening screen 10 can be replaced by a screening screen 10 of different density to meet the corresponding separation requirements through the detachable screening and separation mechanism.

[0023] Specifically, the detachable screening and separation mechanism includes a screen frame 9 that is detachably installed on the lower surface of the separation cylinder 3. A screening screen 10 is provided on the inner side of the screen frame 9, and a positioning hole 14 is provided on the screen frame 9.

[0024] With the above technical solution, the diameter of the positioning hole 14 is the same as the diameter of the positioning rod 11, which means that the positioning rod 11 can be inserted into the positioning hole 14.

[0025] Specifically, a positioning rod 11 is slidably connected to the inner surface of the separating cylinder 3, a collar 12 is fixedly sleeved on the outer surface of the positioning rod 11, and a spring 13 is movably sleeved on the outer surface of the positioning rod 11.

[0026] Through the above technical solution, the two ends of the spring 13 are fixedly connected to the outer surface of the separating cylinder 3 and the collar 12 respectively. Under normal conditions, under the elastic reset action of the spring 13, the positioning rod 11 will be indirectly pulled and inserted into the positioning hole 14, which will limit the position of the mesh frame 9.

[0027] Specifically, the fastening mechanism includes a chuck 18 fixedly connected to the bottom of the receiving tray 17, and the chuck 18 is made of rubber.

[0028] With the above technical solution, the rubber chuck 18 is unable to break free from the V-shaped groove 16 after being resisted (from bottom to top) by the clamping piece 20.

[0029] Specifically, the device frame 1 is provided with a sliding groove 15 and a V-shaped slot 16, and the sliding groove 15 and the V-shaped slot 16 are on the same horizontal plane.

[0030] Through the above technical solution, the chute 15 supports the receiving tray 17 and guides the receiving tray 17 to move in the correct direction so that the chuck 18 can be engaged in the V-shaped groove 16.

[0031] Specifically, the bottom of the device frame 1 is threaded with a screw 19, and the top of the screw 19 is provided with a clamping plate 20.

[0032] Through the above technical solution, the rotary nail 19 can gradually move upward during the screwing process, thereby driving the clamping plate 20 to gradually approach the chuck 18 and achieve the limiting effect of docking the material tray 17.

[0033] Working principle: In the process of screening and separating agricultural products, the receiving tray 17 needs to be installed in a suitable position first, that is, the bottom of the receiving tray 17 is locked in the slide groove 15, and at the same time, it moves along the slide groove 15 towards the V-shaped groove 16, until the chuck 18 is laterally close to being locked in the V-shaped groove 16, and is completely locked in the V-shaped groove 16. Then, the screw 19 is turned. During the rotation of the screw 19, the clamping plate 20 will gradually move upward until the clamping plate 20 completely abuts against the chuck 18, thereby limiting the chuck 18, so that the receiving tray 17 is locked in place. 7 is in a stable installation state. When it is necessary to remove the receiving tray 17, simply release the limit on the chuck 18. After the installation of the receiving tray 17 is completed (at this time, the receiving tray 17 is installed directly below the screening screen 10), put an appropriate amount of agricultural product material into the feeding hopper 4 and let it fall into the separation cylinder 3. Then, shake the handle 8 to drive the rotating shaft 6 to rotate. During this process, the material-pushing plate 7 will rotate accordingly and push the material during the rotation, so that it is mixed and screened and separated at the screening screen 10. Some of the smaller agricultural products and others are separated. The material passes through the screening screen 10 and falls into the receiving tray 17 below, while the rest remains in the separation cylinder 3. After the screening and separation operation is completed, the separation cylinder 3 can be rotated along the frame shaft 2, thereby pouring out the agricultural product material remaining in the separation cylinder 3 from the discharge hopper 5, thus completing the entire separation operation of the agricultural product. Considering that different agricultural products require different degrees of screening, the screen frame 9 and screening screen 10 on the separation cylinder 3 can be replaced with a screening screen 10 with a suitable mesh density. This process requires pulling the positioning rod 11 outward. The spring 13 can be stretched by the collar 12 to deform it until the positioning rod 11 is pulled out of the positioning hole 14, so that the screen frame 9 and the screening screen 10 can be easily removed. After replacing the screen frame 9 and the screening screen 10, simply install the screen frame 9 in a suitable position on the lower surface of the separation cylinder 3, and then release the positioning rod 11. Under the elastic deformation and reset action of the spring 13, the positioning rod 11 can be reinserted into the positioning hole 14, so that the screen frame 9 can be quickly positioned and installed, thus completing the purpose of replacing and installing the screening screen 10 with different mesh densities.

[0034] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
