Abstract
Description
Technical Field
[0001] This utility model relates to the field of animal husbandry technology, specifically to a licorice stem and leaf feed pretreatment device. Background Technology
[0002] Licorice stems and leaves are rich in nutrients such as protein, minerals and various vitamins, which can effectively supplement the nutritional deficiencies in the daily feed of cattle and sheep, enhance their immunity, improve their disease resistance, and also improve their digestive function.
[0003] When licorice stems and leaves are used as feed, they usually need to be pre-processed by crushing in order to improve their palatability, nutritional value and digestibility. At present, crushers or shredders are generally used to crush or shred them. However, since the roots of licorice are covered with a lot of soil after being pulled out, the existing licorice stem and leaf pre-processing devices do not have the function of cleaning the soil. The soil still needs to be shaken off manually, which is inefficient. Therefore, there is a need for a licorice stem and leaf feed pre-processing device that can improve the processing efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide a licorice stem and leaf feed pretreatment device to solve the problem mentioned in the background art that, after licorice is pulled out, its roots will have a lot of soil attached to them. The existing licorice stem and leaf pretreatment devices do not have the function of cleaning the soil and still need to be manually shaken off the soil, which is inefficient.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a licorice stem and leaf feed pretreatment device, comprising a placement hopper and a crusher, wherein the placement hopper is installed on the side wall of the feed end of the crusher, and a screening mechanism is installed inside the placement hopper, wherein the screening mechanism can screen the soil on the external licorice stems and leaves.
[0006] The screening mechanism includes a rotating shaft, a connecting sleeve, a screen plate, a motor, and a cam. The rotating shaft is installed on the inner side wall of the placement hopper, and the connecting sleeve is sleeved on the outer side of the rotating shaft. The screen plate is installed on the side wall of the connecting sleeve. The motor is installed on the inner side wall of the placement hopper, and a cam is installed on the output end of the motor. The cam is located on the lower wall of the screen plate and can fit against the lower wall of the screen plate.
[0007] Both the crusher and the motor are electrically connected to an external power source.
[0008] As a preferred embodiment of this utility model, a discharge mechanism is installed on the inner wall of the placement hopper. The discharge mechanism is located below the screening mechanism. The discharge mechanism includes an installation shaft and a discharge plate. The installation shaft is installed on the inner wall of the placement hopper, and the discharge plate is rotatably installed on the outer wall of the installation shaft. The discharge plate is located below the screen plate and can collect the soil that has been screened out.
[0009] As a preferred embodiment of this utility model, one end of a connecting rope is installed on the upper wall of the discharge plate, and the other end of the connecting rope is installed on the lower wall of the screen plate.
[0010] As a preferred embodiment of this utility model, a buffer rubber pad is fitted to the inner wall of the placement hopper, and the buffer rubber pad is positioned below the discharge plate.
[0011] As a preferred embodiment of this utility model, a sealing gasket is fitted to the edge of the discharge plate, and the sealing gasket can fit against the inner wall of the placement hopper.
[0012] As a preferred embodiment of this utility model, a guide plate is installed on the inner side wall of the placement hopper. The guide plate is made of rubber, one end of which is attached to the upper wall of the sieve plate, and the other end of which is inserted into the feed end of the crusher.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This device uses a hopper at the feed end of the crusher. The vibration of the screen plate inside the hopper quickly shakes off the soil and stones attached to the licorice stems and leaves, causing them to fall onto the discharge plate for discharge. Compared to manual cleaning, this is faster, less labor-intensive, and has a better cleaning effect, making it very convenient.
[0015] In addition, the device is connected to the screen plate and the discharge plate by a connecting rope, so that the screen plate can drive the discharge plate to move up and down, thereby facilitating the discharge of soil from the discharge plate. Attached Figure Description

[0020] 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.
[0021] Please see Figure 1-3 This utility model provides a technical solution:
[0022] In this technical solution, a licorice stem and leaf feed pretreatment device includes a placement hopper 1 and a crusher 2. The placement hopper 1 is installed on the side wall of the feed end of the crusher 2. A screening mechanism 3 is installed inside the placement hopper 1. The screening mechanism 3 can screen the soil on the external licorice stems and leaves.
[0023] The screening mechanism 3 includes a rotating shaft 31, a connecting sleeve 32, a screen plate 33, a motor 34, and a cam 35. The rotating shaft 31 is installed on the inner side wall of the placement hopper 1, and the connecting sleeve 32 is sleeved on the outer side of the rotating shaft 31. The screen plate 33 is installed on the side wall of the connecting sleeve 32. The motor 34 is installed on the inner side wall of the placement hopper 1. The output end of the motor 34 is equipped with a cam 35. The cam 35 is located on the lower wall of the screen plate 33 and can fit against the lower wall of the screen plate 33.
[0024] Both the crusher 2 and the motor 34 are electrically connected to an external power source;
[0025] In this technical solution, when licorice stems and leaves need to be pre-treated, the licorice stems and leaves are placed in the placement hopper 1, and the motor 34 is started. The motor 34 drives the cam 35 to rotate. Since the cam 35 is in contact with the lower wall of the sieve plate 33, as the cam 35 rotates, its contour shape changes, which pushes the sieve plate 33 to swing back and forth around the rotating shaft 31. During the swinging process of the sieve plate 33, the licorice stems and leaves are constantly turned over on the sieve plate 33. The soil attached to the licorice stems and leaves falls off due to the sieve holes of the sieve plate 33, thereby achieving the screening of soil from the licorice stems and leaves, preventing soil from entering the crusher 2, reducing the wear of the internal parts of the crusher 2, improving the service life of the crusher 2, and also ensuring the purity of the licorice stem and leaf feed processed later.
[0026] In some technical solutions, a discharge mechanism 4 is installed on the inner wall of the placement hopper 1. The discharge mechanism 4 is located below the screening mechanism 3. The discharge mechanism 4 includes a mounting shaft 41 and a discharge plate 42. The mounting shaft 41 is installed on the inner wall of the placement hopper 1. The discharge plate 42 is rotatably installed on the outer wall of the mounting shaft 41. The discharge plate 42 is located below the screen plate 33. The discharge plate 42 can collect the soil that is screened out.
[0027] In this technical solution, the screened soil falls onto the discharge plate 42, which is rotatably mounted on the inner wall of the placement hopper 1 via the mounting shaft 41, and can guide the screened soil to be discharged from the placement hopper 1.
[0028] In some technical solutions, one end of a connecting rope 5 is installed on the upper wall of the discharge plate 42, and the other end of the connecting rope 5 is installed on the lower wall of the screen plate 33.
[0029] In this technical solution, when the screen plate 33 reciprocates under the action of the cam 35, it will drive the discharge plate 42 to swing synchronously with a small amplitude through the connecting rope 5. This linkage method allows the soil on the discharge plate 42 to slide off and be discharged more smoothly during the screening process, avoiding the accumulation of soil on the discharge plate 42, further improving the efficiency of soil discharge, and also reducing the amount of manual cleaning of residual soil on the discharge plate 42.
[0030] In some technical solutions, a buffer rubber pad 6 is fitted to the inner wall of the hopper 1, and the buffer rubber pad 6 is located below the discharge plate 42.
[0031] In this technical solution, when the discharge plate 42 rotates to discharge the soil, the discharge plate 42 may collide with the inner wall of the placement hopper 1. The presence of the buffer rubber pad 6 can effectively buffer the impact force generated when the discharge plate 42 collides with the inner wall of the placement hopper 1, reduce collision noise, protect the structural integrity of the discharge plate 42 and the placement hopper 1, extend the service life of the equipment, and reduce equipment damage and maintenance costs caused by collision.
[0032] In some technical solutions, a sealing gasket 7 is fitted to the edge of the discharge plate 42, and the sealing gasket 7 can fit against the inner wall of the placement hopper 1.
[0033] In this technical solution, the sealing gasket 7 fits snugly against the inner wall of the placement hopper 1, which can effectively prevent fine particles such as soil from leaking out from the gap between the discharge plate 42 and the inner wall of the placement hopper 1 during the screening process. This ensures the cleanliness of the internal environment of the placement hopper 1, avoids soil contamination of the work site, and also prevents soil from entering other parts of the equipment and affecting the normal operation of the equipment.
[0034] In some technical solutions, a guide plate 8 is installed on the inner side wall of the hopper 1. The guide plate 8 is made of rubber. One end of the guide plate 8 is attached to the upper wall of the screen plate 33, and the other end of the guide plate 8 is inserted into the feed end of the crusher 2.
[0035] In this technical solution, the licorice stems and leaves that have been screened on the sieve plate 33 will move towards the edge of the sieve plate 33 under their own weight and the swinging action of the sieve plate 33. One end of the guide plate 8 is attached to the upper wall of the sieve plate 33, and the other end is inserted into the feed end of the crusher 2. This can guide the licorice stems and leaves to smoothly enter the feed end of the crusher 2, prevent the licorice stems and leaves from accumulating or scattering in the placement hopper 1, and ensure that the licorice stems and leaves can continuously and stably enter the crusher 2 for crushing, thereby improving the efficiency of feed pretreatment.
[0036] Working principle: The licorice stems and leaves to be processed are placed on the sieve plate 33 in the placement hopper 1. Then, the motor 34 is started. The motor 34 drives the cam 35 to rotate. Since the cam 35 is in contact with the lower wall of the sieve plate 33, as the cam 35 rotates, its contour shape changes, which pushes the sieve plate 33 to swing back and forth around the rotating shaft 31. During the swinging process of the sieve plate 33, the licorice stems and leaves are constantly turned on the sieve plate 33. The soil attached to the licorice stems and leaves falls off due to the action of the sieve holes of the sieve plate 33, thereby realizing the screening of the soil on the licorice stems and leaves. The screened licorice stems and leaves will move towards the edge of the sieve plate 33 under the action of their own gravity and the swinging action of the sieve plate 33. The licorice stems and leaves are guided smoothly into the feed end of the crusher 2 by the guide plate 8, and then crushed by the crusher 2.
[0037] The sifted soil will pass through the mesh on the sieve plate 33 and fall onto the discharge plate 42, and then be discharged into the placement hopper 1.
