Description

Technical Field

[0001] The utility model relates to the technical field of livestock feed processing, in particular to a feed crushing and stirring tank. Background Art

[0002] In the livestock and veterinary industry, a feed crushing and stirring machine is a very important piece of equipment. It is mainly used to crush or pulverize materials and then mix them to meet the nutritional needs of animals and improve the utilization efficiency of feed.

[0003] A livestock and veterinary feed crushing and stirring tank disclosed in Chinese Patent Publication No. CN218013135U can ensure the crushing effect while crushing the feed, and continuously crush feeds of different sizes until they are fine enough.

[0004] However, compared with the prior art in related fields, in order to ensure the crushing effect, a crushing screen is usually set in the crushing area. In actual use, the mesh holes of the crushing screen are prone to blockage. If not cleaned in time, it will affect the crushing progress of the materials, and at the same time cause excessive crushing of the materials, affecting the quality of the materials. If cleaned in time, the equipment needs to be shut down, thus affecting the processing and crushing efficiency of the equipment. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a feed crushing and stirring tank.

[0006] The purpose of the utility model is realized through the following technical solutions: a feed crushing and stirring tank, including a main box body. A crushing mechanism is arranged in the upper half area inside the main box body, and a stirring mechanism is arranged in the lower half area inside the main box body;

[0007] The crushing mechanism includes a crushing box fixedly installed inside the main box body. A crushing shaft for crushing or pulverizing materials is rotatably arranged inside the crushing box, and a self-cleaning screening component is arranged at the bottom of the crushing box;

[0008] The self-cleaning screening component includes a crushing screen connected to the crushing box through an elastic telescopic component. The shape of the crushing screen is arc-shaped. An activity screen is movably connected inside the crushing screen. The mesh holes of the crushing screen and the activity screen correspond to each other. Flexible plates are fixedly arranged at both ends of the crushing screen. When the crushing screen drops due to blockage, both ends of the crushing shaft intermittently contact the flexible plates, thereby prompting the activity screen to reciprocate inside the crushing screen.

[0009] Preferably, the stirring mechanism includes a stirring shaft rotatably arranged inside the main box body. The bottom of the main box body is semi-circular, and the stirring shaft is adapted to the semi-circle of the main box body.

[0010] Preferably, the crushing screen and the movable screen are both semi-circular in shape, and the flexible plate is arc-shaped.

[0011] Preferably, accommodation grooves are provided at the positions of the crushing box corresponding to the two flexible plates, and the flexible plates are connected to the tops of the accommodation grooves through elastic ropes.

[0012] Preferably, a feeding port is provided at the top of the main box body, a discharging port is provided at the bottom of the main box body, a first motor and a second motor are fixedly installed on the back of the main box body, the output end of the first motor penetrates through the main box body and is connected to the crushing shaft in a matching manner, the output end of the second motor penetrates through the main box body and is connected to the stirring shaft in a matching manner, a box door is fixedly installed on the front side of the main box body, and a baffle is inserted at the position of the box door corresponding to the discharging port, and the baffle is used to close the discharging port.

[0013] Preferably, the elastic telescopic assembly includes a first sleeve fixedly installed on the crushing screen, a second sleeve is sleeved on the outer surface of the first sleeve, and the first sleeve and the second sleeve are connected through an elastic member in a matching manner.

[0014] Beneficial effects:

[0015] In the feed crushing and stirring tank, by setting the self-cleaning screening component and the elastic telescopic component, when crushing or pulverizing materials in a horizontal container, the cooperation between the crushing screen and the elastic telescopic component can be used to monitor in real time whether the mesh holes of the crushing screen are blocked. When a large number of mesh holes of the crushing screen are blocked, the gravity of the crushing screen plus the materials will be greater than the pulling force of the elastic telescopic component, and then the crushing screen will drive the movable screen and the flexible plate to move downward. At this time, both ends of the crushing shaft will intermittently contact the flexible plate. When the movable screen reciprocates inside the crushing screen, since the mesh holes of the movable screen and the crushing screen are misaligned, the movable screen can extrude the materials stuck inside the mesh holes of the crushing screen, thereby realizing the function of self-cleaning the mesh holes, ensuring the crushing progress of the materials, and avoiding excessive crushing or pulverizing of the materials by the crushing shaft.

Detailed implementation manners

[0026] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0027] Additional aspects and advantages of the present utility model will be further given in the following description in conjunction with the drawings, and some will become obvious from the following description or be understood through the practice of the present utility model.

[0028] Such as Figures 1 to 8As shown in the figure, a feed crushing and stirring tank includes a main box body 1. A crushing mechanism is provided in the upper half area inside the main box body 1, and a stirring mechanism is provided in the lower half area inside the main box body 1. The crushing mechanism includes a crushing box 21 fixedly installed inside the main box body 1. A crushing shaft 22 for crushing or pulverizing materials is rotatably provided inside the crushing box 21. A self-cleaning screening component 3 is provided at the bottom of the crushing box 21. The self-cleaning screening component 3 includes a crushing screen 31 cooperatively connected with the crushing box 21 through an elastic telescopic component 4. The shape of the crushing screen 31 is arc-shaped. An activity screen 32 is movably connected inside the crushing screen 31. The mesh holes of the crushing screen 31 and the activity screen 32 correspond to each other. Flexible plates 33 are fixedly provided at both ends of the crushing screen 31. When the crushing screen 31 drops due to blockage, both ends of the crushing shaft 22 intermittently contact the flexible plates 33, thereby prompting the activity screen 32 to reciprocate inside the crushing screen 31.

[0029] As a preferred technical solution of the present utility model, as Figure 4 shown in the figure, the stirring mechanism includes a stirring shaft 51 rotatably provided inside the main box body 1. The bottom of the main box body 1 is semi-circular, and the stirring shaft 51 is adapted to the semi-circle of the main box body 1. The semi-circle at the bottom of the main box body 1 can ensure the complete discharge of materials.

[0030] As a preferred technical solution of the present utility model, as Figures 5 to 7 shown in the figure, the shapes of both the crushing screen 31 and the activity screen 32 are semi-circular, and the shape of the flexible plate 33 is arc-shaped. When the crushing screen 31 remains in its original position, both ends of the crushing shaft 22 do not contact the flexible plate 33, thereby ensuring that the crushing screen 31 can normally screen materials. When the crushing screen 31 drops, the crushing screen 31 and the activity screen 32 will be eccentric with the crushing shaft 22, so both ends of the crushing shaft 22 will contact the flexible plate 33 (as Figure 6 shown in the figure, which shows one section of the crushing shaft 22. The diameters of the outer surfaces at both axial ends of the crushing shaft 22 are larger than the diameter of the outer surface at the middle part thereof).

[0031] As a preferred technical solution of the present utility model, as Figure 5 and Figure 6 shown in the figure, receiving grooves 2101 are provided at the positions of the crushing box 21 corresponding to the two flexible plates 33. The flexible plates 33 are cooperatively connected with the top of the receiving grooves 2101 through elastic drawstrings 3301. When both ends of the crushing shaft 22 intermittently contact the flexible plates 33, the activity screen 32 will move inside the crushing screen 31. When the crushing shaft 22 does not contact the flexible plate 33, the elastic drawstrings 3301 will pull the activity screen 32 back, thereby realizing the reciprocating movement of the activity screen 32 inside the crushing screen 31.

[0032] As a preferred technical solution of the present utility model, as Figures 1 to 4As shown in the figure, a feeding port 101 is provided at the top of the main box body 1, and a discharging port 102 is provided at the bottom of the main box body 1. A first motor 6 and a second motor 7 are fixedly installed on the back of the main box body 1. The output end of the first motor 6 penetrates the main box body 1 and is connected to the crushing shaft 22 in a matching manner. The output end of the second motor 7 penetrates the main box body 1 and is connected to the stirring shaft 51 in a matching manner. A box door 8 is fixedly installed on the front side of the main box body 1. A baffle 801 is inserted at the position of the box door 8 corresponding to the discharging port 102. The baffle 801 is used to close the discharging port 102. Firstly, when it is necessary to discharge the crushed material, by pulling out the baffle 801, the crushed material can be discharged from the discharging port 102 centrally. At the same time, the semi-circle at the bottom of the main box body 1 can ensure the complete discharge of the material. Secondly, when it is necessary to clean the crushing mechanism and the stirring mechanism, the box door 8 can be disassembled to clean the inside of the main box body 1, the crushing mechanism, the stirring mechanism and the crushing screen 31, so as to ensure the quality of feed processing.

[0033] As a preferred technical solution of the present utility model, as Figures 6 to 8 shown, the elastic telescopic assembly 4 includes a first sleeve 41 fixedly installed on the crushing screen 31. A second sleeve 42 is sleeved on the outer surface of the first sleeve 41. The first sleeve 41 and the second sleeve 42 are connected by an elastic member 43 in a matching manner. The specific structure and connection relationship of the elastic telescopic assembly 4 are introduced. When the crushing screen 31 is not blocked or has fewer blocked mesh holes, the gravity of the crushing screen 31 plus the material will be less than the pulling force of the elastic telescopic assembly 4, so that the crushing screen 31 can be kept in its original position. When the mesh holes of the crushing screen 31 are blocked more, the gravity of the crushing screen 31 plus the material will be greater than the pulling force of the elastic telescopic assembly 4, and then the crushing screen 31 will drive the movable screen 32 and the flexible plate 33 to move downward.

[0034] The working process is as follows:

[0035] S1, as Figures 1 to 4 shown, during crushing, the material is fed into the crushing box 21 through the feeding port 101, and then the crushing shaft 22 is controlled to rotate by the first motor 6 to crush or break the material;

[0036] S2, as Figures 1 to 5 shown, when the material is crushed or broken, the qualified material will sequentially pass through the mesh holes of the crushing screen 31 and the movable screen 32 and fall into the area where the stirring shaft 51 is located, and then the crushed material is stirred by the second motor 7;

[0037] S3, as Figure 5 and Figure 6As shown, when the crushing screen 31 is not blocked or has fewer blocked mesh holes, the gravity of the crushing screen 31 plus the material will be less than the pulling force of the elastic telescopic component 4, so that the crushing screen 31 can be kept in its original position. When the mesh holes of the crushing screen 31 are blocked more, the gravity of the crushing screen 31 plus the material will be greater than the pulling force of the elastic telescopic component 4, and then the crushing screen 31 will drive the movable screen 32 and the flexible plate 33 to move downward. At this time, both ends of the crushing shaft 22 will intermittently contact the flexible plate 33;

[0038] S4. As Figure 5 and Figure 6 shown, when both ends of the crushing shaft 22 intermittently contact the flexible plate 33, the movable screen 32 will move inside the crushing screen 31. When the crushing shaft 22 does not contact the flexible plate 33, the elastic cord 3301 will pull the movable screen 32 back, so as to realize the reciprocating movement of the movable screen 32 inside the crushing screen 31;

[0039] S5. As Figure 7 shown, when the movable screen 32 reciprocates inside the crushing screen 31, since the mesh holes of the movable screen 32 and the crushing screen 31 are misaligned, the movable screen 32 can extrude the material stuck inside the mesh holes of the crushing screen 31, so as to realize the function of self-cleaning the mesh holes and ensure the crushing progress of the material;

[0040] S6. As Figure 3 and Figure 4 shown, when it is necessary to discharge the crushed material, by pulling out the baffle 801, the crushed material can be centrally discharged from the discharge port 102. At the same time, the semi-circle at the bottom of the main box body 1 can be used to ensure the complete discharge of the material.

[0041] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
