Description

Technical Field

[0001] The invention relates to the technical field of composite premix processing, in particular to a feeding mechanism for improved composite premix automatic processing equipment. Background Art

[0002] A compound premix refers to a mixture of one or more additive raw materials and a carrier or diluent that is evenly stirred. It is also called an additive premix or premix. Its purpose is to facilitate the uniform dispersion of trace amounts of raw materials in a large amount of compound feed. Premix feed cannot be fed directly to animals.

[0003] The feeding mechanism on the previous generation of automatic composite premix processing equipment is composed of four parts: a feeding seat, an upper cover, a feeding hopper and a partition frame. Although it can realize the simultaneous feeding operation of multiple materials, the problem of blockage and material jamming is prone to occur during the feeding process, and the operator is required to use tools to assist in the feeding operation. At the same time, the materials cannot be effectively mixed, screened and ground. Large particles of material directly enter the automatic composite premix processing equipment without being processed, which is easy to increase the equipment operation load and work intensity, and at the same time will cause the processed composite premix to have problems such as uneven particles, insufficient mixing and reduced quality of the finished product.

[0004] In view of this, it is particularly important to design and manufacture a feeding mechanism that can reduce blockage during the feeding process of various materials, and at the same time perform preliminary rough processing operations such as mixing, screening and grinding of materials to improve the quality of the finished product after composite premix processing. It is particularly important to use it in automatic processing equipment for composite premixes. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the feeding mechanism of the previous generation of automatic composite premix processing equipment is prone to blockage during the feeding process and cannot perform a series of rough processing operations on the material, resulting in the general quality of the processed composite premix product, and to propose an improved feeding mechanism for automatic composite premix processing equipment.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A feeding mechanism for improved composite premix automatic processing equipment comprises a feeding seat with open upper and lower ends, an upper cover detachably mounted on the upper end of the feeding seat, a feeding hopper fixed to the middle of the upper end of the upper cover, and a partition frame mounted on the inner side of the feeding hopper for separating the feeding hopper into multiple zones, a screen installed in the middle of the feeding seat, and a rough processing mechanism for comprehensive material mixing, screening and grinding operations after the material enters the feeding seat is arranged between the feeding seat and the screen.

[0007] As a further description of the above technical solution: The rough processing mechanism includes a middle material mixing part arranged between the feeding seat and the middle part of the screen, a grinding part arranged between the feeding seat and the left end of the screen, and a transmission part arranged between the middle part and the right end of the feeding seat and used for the linkage operation of the material mixing part and the grinding part.

[0009] As a further description of the above technical solution: The grinding part includes a side cover detachably mounted at the middle of the left end of the feeding seat, a fixed grinding disc fixed at the middle of the left end of the feeding seat and located on the inner side of the side cover, a left-mounted transmission shaft rotatably mounted between the feeding seat and the side cover and transversely passing through the fixed grinding disc, and a dynamic grinding disc mounted at the left end of the left-mounted transmission shaft and located between the side cover and the fixed grinding disc.

[0010] As a further description of the above technical solution: The left end of the feed seat is located above the screen and is provided with a feed hole connected to the upper half cavity of the side cover. The left end of the feed seat is located below the screen and is provided with a discharge hole connected to the lower half cavity of the side cover.

[0011] As a further description of the above technical solution: The transmission part comprises a support frame detachably mounted on the middle of the right end of the feeding seat, a driving motor mounted on the right end of the support frame, a right-mounted driving shaft mounted on the left end of the driving motor through a coupling and coaxial with the left-mounted driving shaft, and a transmission box arranged between the lower end of the middle rotating shaft, the right end of the left-mounted driving shaft and the left end of the right-mounted driving shaft.

[0012] As a further description of the above technical solution: The transmission box includes transmission bevel gears fixed on the lower end of the central rotating shaft, the right end of the left transmission shaft and the left end of the right transmission shaft and meshing with each other, and a transmission box cover symmetrically installed on the front and rear sides of the lower end of the central rotating shaft, the right end of the left transmission shaft and the left end of the right transmission shaft, covering the transmission bevel gears.

Large particles that have not passed through the screen are removed by the rotating action of the material mixing scraper. , it can enter the side cover through the feeding hole, and the dynamic grinding disc rotating on the left transmission shaft can continuously rotate to contact the fixed grinding disc in the side cover to grind and crush the large-particle materials. The crushed materials can continue to enter the feeding seat through the discharging hole. This structure can continuously prevent blocking, mix, screen and selectively grind the materials in the feeding process. A series of rough processing operations in the feeding process can make the material particles uniform and preliminarily mixed, which is convenient for the subsequent processing operations of the materials, effectively sharing the subsequent processing operation load and work intensity of the equipment, and also further improving the quality of the finished products after the composite premix processing.

[0020] Specifically, Figure 2 , Figure 3 and Figure 4 As shown, the material mixing part includes a central rotating shaft 4 rotatably installed between the feeding seat 1 and the axis of the screen 3, a mixing plate 401 fixed at the upper end of the central rotating shaft 4 and fitted with the lower end of the feeding hopper 201, and a plurality of mixing scrapers 402 fixed at equal angles in the middle of the central rotating shaft 4 and fitted with the upper end surface of the screen 3. When the central rotating shaft 4 rotates, the mixing plate 401 and the mixing scrapers 402 can rotate synchronously. The rotating mixing plate 401 can rotate the material at the lower end of the feeding hopper 201 in multiple directions and throw it into the feeding seat 1, which can prevent the material from being stuck under the feeding hopper 201 and can perform the first step of mixing the material.

The feed seat 1 The left end is located below the screen 3 and is provided with a discharge hole 106 connected to the lower half of the side cover 101. Large particles that have not passed through the screen 3 can enter the upper half of the side cover 101 along the plane of the screen 3 and the feed hole 105. At this time, the rotating dynamic grinding disc 501 can continuously rotate to contact the fixed grinding disc 10 to perform a rotational grinding operation on the material, which can effectively reduce the particle diameter of the material. Under the combined action of gravity and centrifugal force, the ground material can pass downward through the discharge hole 106 and enter the feed seat 1.

[0022] Specifically, Figure 1-4 As shown, the transmission part is detachably mounted on a support frame 104 in the middle of the right end of the feeding seat 1, a driving motor 8 mounted on the right end of the support frame 104, a right-mounted transmission shaft 6 mounted on the left end of the driving motor 8 through a coupling 801 and coaxial with the left-mounted transmission shaft 5, and a transmission box arranged between the lower end of the middle rotating shaft 4, the right end of the left-mounted transmission shaft 5 and the left end of the right-mounted transmission shaft 6, the transmission box includes a transmission bevel gear 7 fixed on the lower end of the middle rotating shaft 4, the right end of the left-mounted transmission shaft 5 and the left end of the right-mounted transmission shaft 6 and meshingly connected with each other, and a transmission bevel gear 7 symmetrically mounted on the lower end of the middle rotating shaft 4, the left-mounted transmission shaft 5 and the left end of the right-mounted transmission shaft 6.

[0023] Specifically, Figure 1-3 As shown, a mounting frame 102 is fixedly connected to the outer side of the lower end of the feed seat 1, and a plurality of mounting holes 103 are provided on the mounting frame 102. The arrangement of the mounting frame 102 and the mounting holes 103 facilitates the lower end of the feed seat 1 to be fixed to the feed station of the composite premix automatic processing equipment through fasteners.

[0024] Working principle: when in use, the feeding seat 1 can be installed and fixed to the feeding station of the automatic processing equipment for composite premixes through the mounting frame 102 and fasteners, and then the control circuit of the driving motor 8 is connected to the control terminal of the automatic processing equipment for composite premixes, so as to complete the installation operation of the feeding mechanism; in the actual feeding process, the control terminal can be operated in advance to control the driving motor 8 to be energized and work, and when the driving motor 8 is working, it can drive the right transmission shaft 6 to rotate, and under the meshing transmission action of multiple transmission bevel teeth 7, the middle rotating shaft 4 and the left transmission shaft 5 can be driven to rotate synchronously, and multiple materials can be poured into the chamber between the feeding hopper 201 and the partition frame 202 respectively.

The materials whose particle diameters meet the requirements of the screen 3 can, under the combined action of the rotational force and gravity, pass through the screen 3 in advance and fall into the composite premix automatic processing equipment for subsequent processing. The materials that have not passed through the screen 3 can, under the rotational scraping action of the material-leveling scraper 402, pass through the feed hole 105 on the feed seat 1 and fall into the inner side of the side cover 101. The movable grinding disc 501 on the left transmission shaft 5 continuously rotates to contact the fixed grinding disc 10 on the inner side of the side cover 101, and can perform rotational grinding processing on the large particles. The ground materials can be guided from the lower end of the side cover 101 to slide into the feed seat 1 through the discharge hole 106 on the feed seat 1, and then continue to enter the composite premix automatic processing equipment for subsequent processing, thereby completing the material unloading processing operation.
