Description

TECHNICAL FIELD

[0001] The utility model relates to a pasture chopping equipment technical field, specifically a kind of agricultural livestock pasture chopper. BACKGROUND

[0002] The pasture of agricultural livestock is a kind of herbaceous plant mainly used for feeding cattle, sheep, horses and other domestic animals, which is rich in various nutrients and is an important feed source for domestic animals. After being chopped by a chopper, the pasture is more easily swallowed by livestock and poultry, reducing the waste caused by excessively long or hard feed. At the same time, chopped pasture is also convenient to mix with other feed, improving the utilization rate of feed. Therefore, the collected pasture is usually chopped.

[0003] At present, the chopper is driven by power to rotate the cutter at high speed to cut the complete feed input. The chopped pasture is discharged along the discharge hopper (or discharge port) of the chopper to complete the chopping operation of the pasture.

[0004] Since the chopped pasture needs to be guided along the discharge hopper of the neck structure, and the flowability of the pasture is poor, the pasture is prone to blockage in the discharge hopper, which may cause equipment downtime for repair and affect production continuity. SUMMARY

[0005] In view of the deficiencies in the prior art, the utility model provides a pasture chopper for agricultural livestock, which solves the problem of blockage of the discharge hopper of the chopper in the prior art, equipment downtime for repair, and affects the continuity of production.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a pasture chopper for agricultural livestock, comprising a rack and a fixed cabinet on the rack, a chopping mechanism for shearing pasture is arranged in the cabinet, a feed hopper and a discharge hopper are formed on the cabinet, the feed hopper and the discharge hopper are respectively located on the upper and lower sides of the chopping mechanism, the discharge hopper is provided with a cooperating anti-blocking mechanism, and the anti-blocking mechanism moves up and down to avoid accumulation of pasture in the discharge hopper.

[0007] Compared with the prior art, the utility model has the following beneficial effects:

[0008] When the chopper is used, the pasture to be cut is guided into the cabinet along the feed hopper, and the chopped pasture is guided into the discharge hopper position along the cabinet. Since the anti-blocking mechanism can move up and down in the discharge hopper, it can stir (disturb) the pasture accumulated in the discharge hopper to facilitate the smooth discharge of the pasture along the discharge hopper, avoid downtime maintenance as much as possible, and ensure the continuity of production.

[0009] Further, the anti-blocking mechanism comprises a lifting seat and two guide grooves,

[0010] The lifting seat is inserted into and slidably connected to the discharge hopper. The lifting seat divides the discharge hopper into two discharge zones. An arc-shaped guide section is provided on the top of the lifting seat. The guide section is used to allow the hay in the machine box to be discharged along the two discharge zones.

[0011] The two guide troughs are fixed to the lifting base respectively, and are used to guide the pasture from the two discharge zones.

[0012] Furthermore, there are no anti-clogging components in each discharge zone. The anti-clogging components include a rotating shaft, multiple blades mounted on the rotating shaft, and a rotating motor for driving the rotating shaft.

[0013] Furthermore, a cylinder is fixed at the bottom of the frame, which is used to drive the anti-blocking mechanism to move up and down.

[0014] Furthermore, at least one receiving box for receiving hay is provided below the discharge hopper.

[0015] Furthermore, the receiving box is detachably connected to the support components installed on the frame.

[0016] Furthermore, the shredding mechanism includes two shredding elements arranged side by side.

[0017] Each crushing component includes a crushing shaft, a crushing motor, and multiple crushing blades. The crushing shaft is mounted inside the machine housing and is rotatably connected to the machine housing. The crushing motor is coaxially mounted with the crushing shaft, and the crushing blades are spaced apart along the length of the crushing shaft.

[0018] Furthermore, the multiple crushing blades corresponding to any one crushing component are arranged alternately with the multiple crushing blades corresponding to another crushing component. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] like Figure 2 , 3 As shown, an agricultural and livestock forage shredder includes a frame 100 and a housing 200 fixed on the frame 100. The housing 200 is equipped with a shredding mechanism for cutting forage. The housing 200 has an inlet hopper 210 and an outlet hopper 220, which are located on the upper and lower sides of the shredding mechanism, respectively. The outlet hopper 220 is equipped with a cooperating anti-blocking mechanism 400, which moves up and down to prevent forage from accumulating in the outlet hopper 220.

[0027] Understandably, the frame 100 serves as the mounting and support component for the entire machine, providing a stable structural foundation. Therefore, the frame 100 can have various structures to achieve its function; for example, the frame 100 can be a structure composed of multiple support columns, or other structures. In this application, as... Figure 1 , 2 As shown, the frame 100 includes a rectangular frame-shaped base 140, on which two opposing support seats 130, resembling isosceles trapezoidal frames, are provided. The casing 200 is located between the two support seats 130, and two connecting frames 150 are fixed to the outside of the casing 200, both of which are fixed to the two support seats 130. The frame 100 supports the casing 200, and the discharge hopper 220 of the casing 200 is suspended in the air so that the pulverized forage inside the casing 200 can be smoothly discharged for the next processing step.

[0028] The chassis 200 of this application adopts a rectangular structure. A feed hopper 210 is provided on the top of the chassis 200 to facilitate the smooth introduction of hay into the chassis 200. Inside the chassis 200, below the feed hopper 210, there is a shredding mechanism for crushing / cutting hay. The shredding mechanism can use existing high-speed rotating cutting blades or other structures. Its purpose is to cut the hay. The shredded hay will be guided along the discharge hopper 220 under the action of gravity.

[0029] The discharge hopper 220 in this application is a component of the chassis 200. The discharge hopper 220 consists of an upper constricted structure and a lower rectangular through-slot structure, so the overall structure of the discharge hopper 220 is "hopper-shaped". Due to the poor flowability of hay, it is easy to accumulate in the discharge hopper 220 when it enters the upper and lower connecting positions. Therefore, the discharge hopper 220 of this application is equipped with a cooperating anti-blocking mechanism 400. The anti-blocking mechanism 400 can be a plate-shaped structure, a rod-shaped structure or other block-shaped structure. When the anti-blocking mechanism 400 moves up and down, the hay accumulated at the discharge port will be moved by the anti-blocking mechanism 400, which will cause the force between the hay to be broken, so that the chopped hay can be smoothly discharged along the discharge hopper 220, avoiding the problem of hay blockage at the discharge hopper 220.

[0030] In some embodiments of this application, in order to enable the anti-blocking mechanism 400 to better agitate and guide the hay piled up in the discharge hopper 220, as in this application, Figure 1 , 2 As shown in Figure 4, the anti-blocking mechanism 400 includes a lifting seat 410 and two guide troughs 440. The lifting seat 410 is inserted into the discharge hopper 220 and slidably connected to the inner wall of the discharge hopper 220. The lifting seat 410 divides the discharge hopper 220 into two discharge zones. A guide part 430 with an arc-shaped plate structure is provided on the top of the lifting seat 410. The guide part 430 is used to allow the hay in the machine box 200 to be discharged along the two discharge zones. The two guide troughs 440 are fixed to the lifting seat 410 respectively and are used to guide the hay from the two discharge zones to be discharged.

[0031] The lower part of the discharge hopper 220 in this application has a rectangular through-slot structure. The lower end of the lifting seat 410 is located at the lower part of the discharge hopper 220, and the upper end of the lifting seat 410 moves up and down in the upper part of the discharge hopper 220. The lifting seat 410 can be a block structure, a shell structure, a plate structure, etc., and the lifting seat 410 can divide the discharge hopper 220 (lower part) into two discharge zones. In this application, if... Figure 4As shown, the lifting seat 410 is a hollow structure consisting of two spaced-apart mounting plates 412 and a connecting plate 413 fixed to the mounting plates 412. The material guide part 430 is located above the two mounting plates 412 and is fixed to the two mounting plates 412 respectively. The two material guide grooves 440 are located below the two mounting plates 412 and are fixed to the two mounting plates 412 respectively. The lifting seat 410 and the material guide part 430 form an integral body 450, which is an arched plate structure. The arched sides of the body 450 are sealed, and the sealed positions are recessed inward to form a sliding groove 411. The sliding groove 411 is slidably connected to the protruding slider inside the discharge hopper 220. The cooperation between the sliding groove 411 and the slider can realize the sliding insertion between the lifting seat 410 and the discharge hopper 220, and also ensure that the discharge hopper 220 is divided into two discharge areas. When the lifting seat 410 and the guide section 430 move up and down together, they can disturb and disperse the hay piled up in the discharge hopper 220. The dispersed hay can be fed out separately under the action of the guide section 430.

[0032] To prevent the hay diverted by the feed guiding section 430 from scattering randomly, this application also provides two opposing intercepting plates 4121 on each mounting plate 412. The area enclosed by the two intercepting plates 4121 and the corresponding mounting plate 412 can be considered as the discharge area. In use, the hay diverted by the feed guiding section 430 will be guided from the two discharge areas and then enter the two feed guiding troughs 440 below. The feed guiding trough 440 is an inclined trough-shaped structure. The upper end of the feed guiding trough 440 is connected and fixed to the lower end of the corresponding mounting plate 412, and the lower part of the feed guiding trough 440 slopes downward away from the mounting plate 412. Thus, the hay entering the feed guiding trough 440 along the discharge area can be smoothly discharged along the feed guiding trough 440.

[0033] In some embodiments of this application, to further prevent hay blockage in the discharge hopper 220, this application does not include an anti-blocking component 420 in each discharge zone. The anti-blocking component 420 includes a rotating shaft 423, multiple blades 422 disposed on the rotating shaft 423, and a rotating motor 421 for driving the rotating shaft 423 to rotate. The anti-blocking component 420 can be installed in conjunction with the discharge hopper 220 or with the lifting seat 410; the anti-blocking component 420 mainly uses the rotating blades 422 to agitate the hay that may accumulate in the discharge zone, so as to facilitate the unloading of the hay. In this application, as... Figure 4As shown, the two anti-blocking components 420 are respectively installed in conjunction with the two mounting plates 412 of the lifting seat 410. Specifically, each rotating shaft 423 passes through the corresponding mounting plate 412 and is rotatably connected to the mounting plate 412 via bearings. The rotating motor 421 connected to the rotating shaft 423 is located in the area between the two mounting plates 412. The rotating motor 421 can be a stepper motor or a servo motor. Multiple blades 422 arranged in a ring on the rotating shaft 423 are used. In use, the two anti-blocking components 420 can be used simultaneously or individually to agitate the forage in the discharge area and prevent the forage from accumulating and clogging.

[0034] In some embodiments of this application, to enable the vertical movement of the entire anti-blocking mechanism 400, a cylinder 500 is fixed on the base 140 of the frame 100. The cylinder 500 is vertically arranged and can be a servo cylinder. The piston rod of the cylinder 500 is fixed to the connecting plate 413 of the lifting seat 410. The cylinder 500 is installed below the space between the two mounting plates 412 to avoid the influence of hay fragments on the cylinder 500. In use, the operation of the cylinder 500 can drive the anti-blocking mechanism 400 to move up and down, preventing blockage of the discharge hopper 220 and ensuring smooth discharge of hay.

[0035] In some embodiments of this application, when the shredder needs to operate continuously in a factory, the hay scraps discharged from the discharge hopper 220 (feeder chute 440) can be conveyed to the next node (or process) via a conveyor belt. If the shredder is used alone at a user's home, to prevent the hay scraps from scattering after being discharged from the discharge hopper 220 (feeder chute 440), this application provides at least one receiving box 110 below the discharge hopper 220 for receiving hay. Figure 1 , 2 As shown, this application provides four receiving boxes 110, which are arranged in pairs. Each pair of receiving boxes 110 is used in conjunction with two guide troughs 440. The two receiving boxes 110 in the same pair are arranged vertically at intervals. In use, taking two receiving boxes 110 in one pair as an example, when the upper receiving box 110 has no storage space, it needs to be moved to allow for cleaning or transfer of the hay inside. At this time, the continuously fed hay will be received by the lower receiving box 110, preventing the hay from scattering from the discharge hopper 220 and ensuring a safe processing environment.

[0036] In some embodiments of this application, to facilitate the positioning and receiving of materials by the receiving box 110, and also to facilitate the assembly and disassembly of the receiving box 110 frame 100, each receiving box 110 is detachably connected to a support member 120 provided on the frame 100. The support member 120 can be a double-layered pull-out frame, in which case the corresponding two receiving boxes 110 can be detachably connected to the support member 120 by plugging in. In this application, as... Figure 1 ,2 As shown in Figure 5, the support member 120 consists of two support rods arranged opposite each other. Each receiving box 110 is mounted between the two support rods. Multiple snap handles 111 are provided around the periphery of each receiving box 110. The snap handles 111 have slots that are adapted to the support rods. Through the cooperation of the snap handles 111 and the two support rods, the receiving box 110 can be detachably connected to the support member 120, so as to facilitate the cleaning and disassembly of the receiving box 110.

[0037] In some embodiments of this application, the shredding mechanism may be, in addition to existing structures, the structure of this application, specifically, such as... Figure 1 , 2 As shown in Figure 3, the shredding mechanism includes two shredding components 300 arranged side by side. Each shredding component 300 includes a shredding shaft 310, a shredding motor 330, and multiple shredding blades 320. The shredding shaft 310 is horizontally arranged and mounted inside the housing 200, and is rotatably connected to the side wall of the housing 200 via bearings. The shredding motor 330 is located on the outer wall of the housing 200 and connected to the housing 200 via a fixing plate 230. The shredding motor 330 is coaxially arranged with the shredding shaft 310 and is either a servo motor or a stepper motor. The shredding blades 320 are spaced apart along the length of the shredding shaft 310. In use, when there is enough hay inside the housing 200 from the feed hopper 210, the hay will come into contact with the shredding blades 320. The shredding blades 320 rotate with the shredding shaft 310, cutting and shredding the contacting hay to achieve the purpose of cutting the hay.

[0038] In some embodiments of this application, to further enhance the shredding effect of the shredding mechanism on forage, as shown in the figure, multiple shredding blades 422 corresponding to any one shredder 300 are arranged alternately with multiple shredding blades 422 corresponding to another shredder 300. The two shredding shafts 310 rotate relative to each other, and the feed hopper 210 is positioned directly above the two shredders 300 to ensure that the forage is shredded as much as possible after entering the machine housing 200. The shredded forage is then discharged along the discharge hopper 220.

[0039] When using the shredder of this application, the forage to be cut is fed into the machine housing 200 through the feed hopper 210. The shredding mechanism inside the machine housing 200 performs shearing and refining treatment. The refined forage is fed into the discharge hopper 220 through the machine housing 200. Since the anti-blocking mechanism 400 can move up and down in the discharge hopper 220, it can move the forage piled in the discharge hopper 220 so that the forage can be discharged smoothly through the discharge hopper 220, minimizing downtime for maintenance and ensuring continuous production.
