[0022] The technical solution of this utility model and how the technical solution solves the above-mentioned technical problems are described in detail below with specific embodiments.

[0023] The forage crushing device provided in the first embodiment of this utility model, such as Figures 1-3 As shown, it includes at least a material cylinder 100, a drive assembly 300, and a crushing blade assembly 200. The material cylinder 100 is typically open with a bottom plate, but may also be equipped with a dedicated removable cover. The material cylinder 100 is cylindrical to facilitate the rotation of the internal crushing blade assembly 200.

[0024] The shredder assembly 200 includes a rotating shaft 210 and an umbrella-shaped blade cover 220. The umbrella-shaped blade cover 220 has several rows of perforated holes 221, with cutting edges on the edges of the perforated holes 221. The umbrella-shaped blade cover 220 has a conical structure with several evenly distributed rows of perforated holes 221 on its surface. Each row has several perforated holes 221. In one embodiment, 6 to 12 rows of perforated holes 221 can be provided, with adjacent rows of perforated holes 221 staggered. Compared to a planar blade cover, the umbrella-shaped blade cover 220 has a larger cutting area. Furthermore, during rotation, the material is thrown up and falls within the feed cylinder 100, resulting in better contact with the blade cover. Therefore, within the same spatial volume, the umbrella-shaped blade cover 220 has higher operating efficiency. The umbrella-shaped cutter cover 220 can be designed with its concave surface facing upwards (i.e., the cone apex facing downwards) or its convex surface facing upwards (i.e., the cone apex facing upwards). Generally, the convex surface of the umbrella-shaped cutter cover 220 is designed to face the top surface of the material cylinder 100, i.e., the cone apex facing upwards. In addition, each perforated hole 221 has a portion of its edge raised. These raised edges are the cutting edges of the perforated hole 221, which better contact the whole piece of forage and cut the forage. From the perforated hole 221, the forage fragments will enter the space below the umbrella-shaped cutter cover 220.

[0025] An umbrella-shaped cutter guard 220 is disposed at one end of a rotating shaft 210, the other end of which is connected to a drive assembly 300. The rotating shaft 210 is mounted on an inner support 110 of the material cylinder 100 so that the umbrella-shaped cutter guard 220 can rotate within the material cylinder 100. Specifically, the drive assembly 300 uses a motor as the main power source, which drives the rotating shaft 210 to rotate, thereby causing the umbrella-shaped cutter guard 220 to rotate within the material cylinder 100. Furthermore, in some implementations, such as... Figure 2 and Figure 3 As shown, in order to protect the rotating shaft 210 and prevent it from rusting, the inner support 110 includes a support cylinder 111 and a support beam 112. The support cylinder 111 is set on the central axis of the material cylinder 100 through the support beam 112; the rotating shaft 210 is set inside the support cylinder 111.

[0026] The forage crushing device provided by this utility model consists of only a material cylinder 100, an umbrella-shaped blade cover 220, and a corresponding drive assembly 300, making its structure very simple. With the cooperation of the material cylinder 100 and the umbrella-shaped blade cover 220, forage such as fruits and vegetables can be directly and thoroughly chopped by the rotation of the umbrella-shaped blade cover 220. The umbrella-shaped blade cover 220 not only cuts the forage but also ensures that the forage remains on the cover surface for as long as possible, thus guaranteeing that the forage is thoroughly chopped. The forage crushing device provided by this application has a simple structure and high cutting efficiency.

[0027] Optionally, in the second embodiment of this utility model, such as Figure 1 and Figure 4As shown, a pressing plate 120 is provided on the inner wall of the feed cylinder 100, and the pressing plate 120 is spaced apart from the cutting surface of the umbrella-shaped cutter cover 220. By providing the pressing plate 120, the forage fed onto the surface of the umbrella-shaped cutter cover 220 is blocked when rotating, preventing the forage from rotating with the umbrella-shaped cutter cover 220, ensuring that the forage and the umbrella-shaped cutter cover 220 move towards each other, thereby ensuring that the forage is cut and crushed.

[0028] In one specific implementation, in conjunction with the foregoing embodiments, the pressing plate 120 is movably disposed on the inner wall of the feed cylinder 100, and the pressing plate 120 can move axially along the feed cylinder 100. The distance between the pressing plate 120 and the umbrella-shaped blade cover 220 is adjustable, which allows for fine-tuning of the blocking effect according to the type of forage. For example, when the forage is melons and fruits, the distance between the pressing plate 120 and the umbrella-shaped blade cover 220 can be increased at the beginning of feeding to improve cutting efficiency. When the melons and fruits are almost cut, the distance can be decreased to ensure that the melons and fruits are fully chopped. Figure 1 As shown, a strip-shaped groove can be set on the material cylinder 100, and the pressure plate 120 can be fixed with bolts and moved or fixed in the strip-shaped groove as needed.

[0029] In conjunction with the foregoing embodiments and implementations, in another specific implementation, such as Figure 5 As shown, the pressing plate 120 is inclined toward the umbrella-shaped blade cover 220. The pressing plate 120 is not vertically upward, nor is its surface parallel to the direction of gravity; rather, it presents a certain angle. When the umbrella-shaped blade cover 220 rotates toward the pressing plate 120, it carries the forage that impacts the pressing plate 120. Because the pressing plate 120 is inclined toward the umbrella-shaped blade cover 220, the forage is clamped. The pressing plate 120 applies pressure to the forage toward the umbrella-shaped blade cover 220, ensuring that the forage is more forcefully pressed onto the surface of the umbrella-shaped blade cover 220 for thorough cutting and crushing.

[0030] Optionally, in a third embodiment of this utility model, such as Figure 2 and Figure 6As shown, the shredder assembly 200 also includes rotating blades 230, which are positioned below the umbrella-shaped blade cover 220 and near the inner support 110. By using rotating blades 230, the shredded forage inside the feed cylinder 100 can be better agitated, preventing caking and facilitating better outward discharge. Specifically, as shown, a discharge cylinder 130 is located beside the bottom surface of the feed cylinder 100. This discharge cylinder 130 allows the prepared forage to be removed, and its outward extension facilitates the output and transfer of the shredded forage. Combined with the rotating blades 230, the forage can be automatically discharged from the discharge cylinder 130. Furthermore, in one implementation of this invention, one inner edge of the discharge cylinder 130 is rounded, and the opposite inner edge is a right angle. The point where the discharge cylinder 130 and the feed cylinder 100 are joined is the inner edge of the discharge cylinder 130. The inner edge with rounded corners is generally downstream in the direction of rotation, resulting in a larger output area and facilitating the output of forage. The inner edge with right angles on the other side is simple to process and assemble, reducing production costs.

[0031] Optionally, in another embodiment of this utility model, the top of the umbrella-shaped cutter cover 220 is at least 30 cm away from the top surface of the feed cylinder 100. Because after the forage is put into the feed cylinder 100, it will bounce and bounce on the rapidly rotating umbrella-shaped cutter cover 220, if the top of the umbrella-shaped cutter cover 220 is too shallow away from the top surface of the feed cylinder 100, the forage will be easily thrown out; therefore, it should be set deeper. Alternatively, a constricted opening can be provided at the top of the feed cylinder 100, but it should not be too small to avoid inconvenience in putting in the forage.

[0032] Those skilled in the art will understand that the terms "first" and "second" discussed in this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0033] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0035] The above description is only a partial embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
