Description

Technical Field

[0001] This utility model relates to the field of forage processing technology, and in particular to a forage shredding machine. Background Technology

[0002] Forage shredding is a technique that uses machinery to process coarse fibrous forage such as straw into soft shreds. It is mainly used to improve the feed intake and digestibility of animals. For example, in goose farming, geese are usually fed forage. In order to improve the palatability of the forage and make it easier for geese to digest, a shredding machine is usually used to process the forage into shreds so that geese can eat it.

[0003] Existing forage shredders mainly consist of a machine body, a cutting section and a shredding section located within the machine body, and an infeed section and a discharge section located on both sides of the machine body. During shredding, the infeed section feeds the forage to the cutting section, where it is chopped. The shredding section then further cuts the chopped forage into shreds, which are then discharged through the discharge section. However, after the existing cutting and shredding sections chop the forage, some scraps often remain inside the machine body. The existing machine body lacks a structure to clear these scraps, making it difficult for them to be discharged. This can easily lead to internal blockages, hindering the rapid discharge of forage and affecting the efficiency of forage shredding. Utility Model Content

[0004] This utility model proposes a forage shredder to solve the problem of residual material inside the existing machine body, which easily causes blockage and makes it difficult to quickly discharge forage.

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.

[0017] Please see Figures 1-5 As shown, a forage shredder includes a frame 1 and a shredding box 2 mounted on the frame 1. A controller for easy operation is located on the side wall of the shredding box 2. A feeding mechanism 4 is located on one side of the shredding box 2, and a discharge hopper 3 is located on the other side. A cutting assembly and a shredding mechanism 5 are located inside the shredding box 2. A transparent observation window is located on one side of the shredding box 2 for easy observation of the shredding process inside. The feeding mechanism 4 includes a feeding frame 41 communicating with the inside of the shredding box 2. Two conveying rollers 43 are rotatably mounted inside the feeding frame 41, and a conveyor belt 42 is wound between the two conveying rollers 43. A first motor 47 is located on one side of the shredding box 2 to drive one of the conveying rollers 43 to rotate. The cutting assembly includes a cutting table 10 fixed to the bottom of the inside of the shredding box 2 and a bracket 7 mounted on the inner wall of the shredding box 2. A cutter 12 is installed on the cutting table 10, and a first electric push rod 8 is installed on the bracket 7. A cutting plate 9 that cooperates with the cutter 12 is connected to the telescopic end of the first electric push rod 8. A through hole for the air supply hose 63 to pass through is also provided inside the cutting table 10. The kneading mechanism 5 includes two symmetrically arranged mounting brackets 51 and a second motor 54 installed on the frame 1. A shaft is rotatably installed between the two mounting brackets 51, and a rotating frame 52 is fixed on the shaft. Multiple equally spaced swivel blades 53 are movably installed on both sides of the rotating frame 52. One end of the shaft extends to the outside of the kneading box 2 and is connected to the main shaft of the second motor 54 by a transmission belt assembly. A protective cover for the transmission belt assembly is detachably installed on the outer wall of the frame 1 and the kneading box 2. It also includes an anti-blocking mechanism to clear the inside of the kneading box 2. The anti-blocking mechanism includes: The feeding assembly 11 includes a feeding plate 111 that can move along the inside of the shredding box 2, for pushing the straw inside the shredding box 2 toward the discharge hopper 3; The purging assembly 6 includes a groove 65 formed on the side of the pusher plate 111 facing the discharge hopper 3, and an air distribution chamber 64 formed inside the pusher plate 111. Multiple air nozzles 62 communicating with the air distribution chamber 64 are installed on the inner wall of the groove 65.

[0018] When processing forage into shreds, the forage can be placed into the feeding rack 41, and then the conveyor belt 42 is driven to rotate by the cooperation of the first motor 47 and the conveying roller 43 to send the forage into the cutting table 10 in the shredding box 2. At this time, the cutting plate 9 is driven to rise and fall by the first electric push rod 8 on the bracket 7, and the forage on the cutting table 10 is cut by the cooperation of the cutter 12. At the same time, the shaft is driven to rotate by the cooperation of the second motor 54 and the transmission belt assembly, and then the shaft drives the rotating frame 52 to rotate, so that the rotating frame 52 drives the sling cutter 53 to rotate, so as to further shred the forage cut in the shredding box 2 into soft shreds, and then discharge it through the discharge hopper 3, thereby realizing the shredding processing of forage, improving the taste of forage, and making it easier to feed geese. Furthermore, during the discharge process, when blockage occurs inside the shredding box 2, the shredding mechanism 5 can be paused, and the movable pusher plate 111 can move along the inside of the shredding box 2 to push the shredded material to the discharge hopper 3 and discharge it, thereby clearing the inside of the shredding box 2 and preventing the accumulation of material inside the shredding box 2 from causing blockage. This facilitates the rapid discharge of the shredding machine. At the same time, the air nozzle 62 moves synchronously with the pusher plate 111 and sprays gas to blow the inside of the shredding box 2, causing the small pieces of material remaining inside the shredding box 2 to be blown out, thus cleaning the inside of the shredding box 2. This further prevents the residue of grass and chaff from remaining inside the shredding box 2 and affecting the discharge of the shredding machine, which is conducive to the rapid discharge of grass and chaff. Secondly, it should be noted that the transmission belt assembly in this embodiment adopts a belt drive transmission method, which is a mature mechanical transmission method in the prior art. Therefore, its structure and principle will not be described in detail here.

[0019] Furthermore, to facilitate the conveying of forage to the cutting table 10, such as... Figure 2 , Figure 3 and Figure 5 As shown, a guide roller 13 is also rotatably installed on the cutting table 10 and on the side near the feeding mechanism 4.

[0020] Preferably, in this embodiment, regarding how the above-mentioned jet nozzle 62 blows air, as follows: Figures 2-5 As shown, the purging assembly 6 also includes an air storage tank 61 mounted on the frame 1. An air supply hose 63 is connected between the air storage tank 61 and the pusher plate 111, and the air supply hose 63 is connected to the air distribution chamber 64. Specifically, the air storage tank 61 is also provided with an air inlet, which can be connected to an external air supply device to facilitate the injection of compressed air into the air storage tank 61 by the external air supply device to achieve compressed air storage. The air supply hose 63 is provided with a pulse solenoid valve. When the jet nozzle 62 needs to spray air, the opening and closing of the pulse solenoid valve is used to facilitate the intermittent spraying of air from the jet nozzle 62 into the kneading box 2 to achieve purging of the kneading box 2.

[0021] Meanwhile, in this embodiment, regarding how the pusher plate 111 moves along the inside of the kneading box 2, as follows: Figure 3 and Figure 5 As shown, the feeding assembly 11 also includes a mounting cavity formed within the cutting table 10. A second electric push rod 112 and a retractable limiting rod 113 are installed within the mounting cavity, and the retractable end of the second electric push rod 112 and one end of the limiting rod 113 are connected to one side of the feeding plate 111. Specifically, in this embodiment, to achieve stable movement of the feeding plate 111 driven by the second electric push rod 112, two limiting rods 113 are provided, and the two limiting rods 113 are symmetrically distributed on both sides of the second electric push rod 112.

[0022] When the pusher plate 111 needs to move, the second electric push rod 112 is activated to drive the pusher plate 111 to move along the bottom of the inside of the shredding box 2. Then the pusher plate 111 pushes the shredded grass towards the discharge hopper 3 to promote the discharge of grass and clear the inside of the shredding box 2.

[0023] In addition, in this embodiment, such as Figure 2 As shown, the feeding mechanism 4 also includes two biting rollers 44 rotatably installed inside the kneading box 2. One end of each biting roller 44 extends to the outside of the kneading box 2 and is equipped with meshing gears 45. A synchronous belt drive 46 connects one end of one biting roller 44 to one end of one conveying roller 43. An outer cover is detachably installed on the outer wall of the kneading box 2 to cover the gears 45 and the synchronous belt drive 46. The first motor 47 is installed on the outer wall of the outer cover. Specifically, the synchronous belt drive 46 consists of a synchronous toothed belt and a toothed pulley that meshes with it. This transmission method is a mature transmission method in the prior art and will not be described in detail here.

[0024] When the conveyor belt 42 feeds the hay into the shredding box 2, one of the conveying rollers 43 drives one of the biting rollers 44 to rotate through the synchronous belt drive component 46. Then, with the cooperation of the meshing gears 45, the two biting rollers 44 rotate towards each other to bite the hay into the shredding box 2, thereby promoting the rapid addition of hay into the shredding box 2 and facilitating the rapid shredding of hay.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
