Description

Technical Field

[0001] This utility model relates to the technical field of forage crushing equipment, specifically to a forage cutting and crushing device. Background Technology

[0002] Cattle and sheep teeth (especially molars) are adapted for grinding actions but have difficulty efficiently tearing long-fiber forage (such as corn stalks and reeds). Unbroken long-fiber forage requires repeated chewing to grind, which consumes a lot of energy. This is especially true for older, weaker cattle and sheep, or young calves and lambs, who often refuse to eat or have insufficient feed intake due to the difficulty of chewing. After being cut and crushed (usually into 2-5cm pieces or granules), the size of the forage particles is uniformly reduced, and the chewing time can be shortened by more than 50%, significantly improving feeding efficiency. This not only reduces energy waste in cattle and sheep but also helps them gain weight efficiently and improve production performance (such as milk production in dairy cows and fattening speed in beef cattle).

[0003] Based on this demand, existing ranches are generally equipped with forage cutters and shredders. The existing forage cutters and shredders mainly consist of a frame, a drive motor, a belt drive assembly, a crushing chamber, and crushing rollers and a screen installed inside the crushing chamber. During operation, the drive motor drives the crushing rollers to rotate at high speed, cutting and crushing the input forage. Forage segments that meet the size requirements will fall through the screen and be collected, while those that do not meet the size requirements will remain in the crushing chamber for further crushing.

[0004] However, there are obvious drawbacks in practical applications: the crushing chamber is mostly a fixed, sealed structure, making it difficult to thoroughly clean the internal dead corners. Residual forage debris during the crushing process is prone to mold and deterioration in humid environments, thus contaminating the forage processed subsequently and increasing the risk of rumen disease and intestinal infections in cattle and sheep. Addressing the core pain point of the existing technology's difficulty in cleaning, this application provides a forage cutting and crushing device. Utility Model Content

[0005] The purpose of this invention is to improve the crushing chamber of the existing forage cutting and crushing machine so that it can be easily opened and cleaned. This invention provides a forage cutting and crushing device.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A forage cutting and crushing device includes a frame, a motor, a belt drive assembly, a crushing chamber, a crushing roller, and a screening screen. The crushing chamber is shaped like a whistle and is divided into a whistle opening part and a whistle drum part. The whistle opening part is welded and fixed to the frame. The whistle drum part is rotatably mounted to the whistle opening part. The inner cavity of the whistle drum part and the whistle opening part are combined to form a crushing chamber. Driving the whistle drum part to rotate around a rotation point can open the rotating chamber.

[0008] Furthermore, the lower port of the whistle portion is a material discharge outlet.

[0009] Furthermore, the inner wall of the crushing chamber formed by the whistle mouth part and the whistle drum part is constructed with a semi-circular arc slot, and two screening screens are provided and inserted into the slots respectively.

[0010] Furthermore, two sides of one end of the screening mesh are respectively provided with slots for engaging the end of another screening mesh.

[0011] Furthermore, a rotating shaft passes through the crushing chamber, the crushing roller is fixedly installed on the rotating shaft, and both ends of the rotating shaft are respectively installed on the frame through bearing seats.

[0012] Furthermore, the motor is mounted on the lower base frame of the machine frame, and the belt drive assembly includes a drive pulley fixed to the end of the motor output shaft and a driven pulley fixedly mounted on one end of the rotating shaft, with a drive belt connecting the drive pulley and the driven pulley.

[0013] Furthermore, the rotating shaft extends outward by 60cm from the end away from the driven wheel, and an auger is fixedly installed outside the extended section of the rotating shaft. A semi-cylindrical cover is fixedly installed on the outer wall of the auger for the whistle mouth part and the whistle drum part. The semi-cylindrical cover is combined and installed outside the auger.

[0014] Furthermore, a feeding hopper is fixedly connected to the semi-cylindrical cover located on the whistle drum section, and the feeding hopper is wider at the top and narrower at the bottom.

[0015] The beneficial effects of this utility model are as follows:

[0016] In this invention, the whistle drum part can be rotated and opened around the rotation point. After opening, the crushing chamber is fully exposed (including the inner wall, crushing roller, and screen installation position). Not only can the screen be directly disassembled, but it can also be rinsed in all directions by a water gun. Compared with the fixed and sealed structure of the traditional crushing chamber, this application is easier to clean.

[0017] When this utility model is working, the motor drives the rotating shaft to rotate, and the auger rotates synchronously at high speed. The feed (with a wide top and narrow bottom design to guide and converge) is forced into the feeding channel by the axial thrust of the auger blades, avoiding blockage caused by insufficient weight or entanglement of long fiber feed. The airtightness of the channel ensures that all feed is introduced into the crushing chamber without leakage or waste. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0025] This embodiment provides a forage cutting and crushing device, mainly used to improve the crushing chamber of existing forage cutting and crushing machines, making it easier to open and clean. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-5 Please provide a detailed explanation:

[0026] Example 1:

[0027] A forage cutting and crushing device includes a frame 1, a motor 2, a belt drive assembly 3, a crushing chamber 4, crushing rollers 5, and a screening screen 6. These are all existing technical structures. This application mainly improves the crushing chamber 4, specifically as follows: The crushing chamber 4 is constructed in the shape of a whistle and is divided into a whistle opening portion 41 and a whistle drum portion 42. The whistle opening portion 41 is welded and fixed to the frame 1. The whistle drum portion 42 is rotatably mounted to the whistle opening portion 41. The inner cavities of the whistle drum portion 42 and the whistle opening portion 41 combine to form the crushing chamber 7. Driving the whistle drum portion 42 to rotate around a pivot point opens the rotating chamber. Compared to the fixed and sealed structure of the traditional crushing chamber 4, which has the disadvantage of easily accumulating forage at the connection between the inner wall and the screening screen 6, and requiring cleaning only through the inlet or outlet, this design allows the whistle drum portion 42 to rotate and open around a pivot point. After opening, the crushing chamber 7 is fully exposed (including the inner wall, the crushing rollers 5, and the mounting position of the screening screen 6). Not only can the screening screen 6 be directly disassembled, but it can also be thoroughly rinsed with a water gun.

[0028] like Figures 1 to 4As shown in this embodiment, the detailed structure of the screening screen 6 in the crushing chamber 4 is described in detail. The lower end of the whistle part 41 is the discharge outlet 8. The inner wall of the crushing chamber 7, which is composed of the whistle part 41 and the whistle drum part 42, is constructed with a semi-circular slot 9. Two screening screens 6 are provided and are inserted into the slots respectively. It should be noted that after the screening screen 6 is inserted into the semi-circular slot 9 from the side, it is also locked with bolts. In order to ensure that the two screening screens 6 are combined into a cylindrical device, the two sides of one end of the screening screen 6 are respectively constructed with a slot 10. The slot 10 is used to connect with the end of the other screening screen 6. Here, the screening screen 6 is divided into two halves, which are positioned by the semi-circular slot 9 on the inner wall of the crushing chamber 4 and locked with bolts. The end slots 10 are connected to form a complete circular cavity. During cleaning, it is only necessary to disassemble and clean.

[0029] like Figure 3 As shown in this embodiment, the installation and driving methods of the crushing roller 5 are described in detail. A rotating shaft 11 passes through the crushing chamber 7. The crushing roller 5 is fixedly installed on the rotating shaft 11. Both ends of the rotating shaft 11 are respectively installed on the frame 1 through bearing seats 12. At the same time, the motor 2 is installed at the lower base of the frame 1, which can ensure that the overall center of gravity is low. The belt drive assembly 3 includes a drive wheel 31 fixed to the end of the output shaft of the motor 2 and a driven wheel 32 fixedly installed at one end of the rotating shaft 11. A drive belt 33 is provided between the drive wheel 31 and the driven wheel 32. During operation: the output shaft of the motor 2 drives the drive wheel 31 to rotate, and the power is transmitted to the driven wheel 32 at the end of the rotating shaft 11 through the drive belt 33, driving the rotating shaft 11 to rotate and thus driving the crushing roller 5 to crush. At the same time, the belt drive has the function of buffering vibration, avoiding the impact of the roller jamming caused by hard impurities in the forage (such as soil clods in straw) on the motor 2, and improving the stability of equipment operation.

[0030] Example 2:

[0031] This embodiment optimizes the following technical solution based on Embodiment 1:

[0032] The shaft 11 extends 60cm outward from the end furthest from the driven wheel 32. An auger 13 is fixedly mounted on the outer side of this extension. A semi-cylindrical cover 14 is fixedly mounted on the outer wall of the auger 13 at the whistle opening portion 41 and the whistle drum portion 42. The semi-cylindrical covers 14 are combined and installed over the auger 13. The auger 13 is installed via the 60cm extension of the shaft 11. One semi-cylindrical cover 14 is fixed to the whistle opening and the whistle drum side. When closed, they form a complete cylindrical feeding channel located at the whistle drum portion 42. A feeding hopper 15 is fixedly connected to the semi-cylindrical cover 14 of 2. The feeding hopper 15 is wider at the top and narrower at the bottom. The design is such that when working, the motor 2 drives the rotating shaft 11 to rotate, and the auger 13 rotates synchronously at high speed. The feed put into the feeding hopper 15 (the design of being wider at the top and narrower at the bottom guides the convergence) is forced into the feeding channel under the axial thrust of the blades of the auger 13, avoiding blockage caused by insufficient weight or entanglement of long fiber feed. The airtightness of the channel ensures that all feed is introduced into the crushing chamber 7 without leakage or waste.

[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
