Description

Technical Field

[0001] The present invention relates to the technical field of forage cutting, and more specifically, to a forage cutting device for livestock husbandry and processing in animal husbandry. Background Art

[0002] Different from forage harvesting, forage cutting is usually a secondary processing of the harvested forage, making the forage after secondary processing suitable for silage, feed processing or directly feeding livestock. Therefore, forage cutting equipment is only suitable for small-scale feed processing, and most of them do not have the functions of automatic feeding or bundling.

[0003] However, since the feeding process is mostly manual, the quantity of forage fed each time fluctuates greatly, resulting in a relatively fast wear rate of most blades of the existing forage cutting devices for livestock husbandry and processing in animal husbandry, which easily causes the length of the cut forage to be uneven, thereby reducing the cutting effect. Summary of the Invention

[0004] The present invention provides a forage cutting device for livestock husbandry and processing in animal husbandry to solve the problem that the existing forage cutting devices for livestock husbandry and processing in animal husbandry cannot adjust the forage cutting amount in real time, which easily causes the length of the cut forage to be uneven, thereby reducing the cutting effect.

[0008] Preferably, the cutting component includes a motor provided on the outer side of the box body. A pair of first belt pulleys are coaxially connected to the output shaft end of the motor. Any one of the first belt pulleys is connected to a second belt pulley through a transmission belt. The second belt pulley is coaxially connected with a rotating frame.

[0009] Preferably, a plurality of cross bars are hinged on the rotating frame, a plurality of cutting wheels are coaxially connected to the cross bars, and the intervals between each pair of adjacent cutting wheels are equal.

[0010] Preferably, a fixed rod coaxially arranged with the second pulley is connected inside the box body, a plurality of card slots are formed on the fixed rod, a plurality of fourth pulleys equal in number to the card slots are coaxially connected to the cross bar, and any one of the fourth pulleys on each cross bar is connected to one of the card slots through a conveyor belt.

[0015] Preferably, a guide plate is arranged at the opening side of the top end of the top cover, and a conveyor belt driven by the motor is arranged on the guide plate.

[0016] Principle and beneficial effects of this technical solution:

[0017] (1) In the present invention, the control component provided can dynamically adjust the amount of forage processed by the cutting component in the box body, prevent the problem that excessive forage entering at one time weakens the cutting effect and at the same time aggravates the tool wear. Before using the control component, first send the forage to be cut to the top end of the top cover through the conveyor belt arranged on the guide plate, and then the forage will fall into the box body through the opening formed at the top end of the top cover;

[0018] When the cutting component is overloaded, the speed of the motor output shaft decreases, resulting in a decrease in the wind force generated by the first impeller, which in turn reduces the downward deflection angle of the baffle plate and ultimately reduces the size of the opening at the top of the top cover, thereby reducing the amount of grass entering and achieving dynamic control of the amount of grass processing.

[0019] (2) The cutting assembly provided in the present invention can cut the grass entering the box. When the motor output shaft rotates, a first pulley coaxially connected to the output shaft will drive the second pulley connected to it through the conveyor belt to rotate. During the process of the rotating frame driving the cross bar to rotate, the cross bar will also rotate by itself and cause the cutting wheel coaxially connected to the cross bar to cut the grass entering the box. After the grass is cut, it will fall into the screening frame through the longitudinal groove provided on the support plate for secondary screening.

[0020] (3) The filter plate provided in the present invention can perform secondary screening on the forage grass entering the screening frame. When the motor rotates, the other first pulley coaxially connected to the output shaft thereof will drive the third pulley coaxially connected to the second impeller to rotate. The second impeller will rotate and generate wind force to blow the inclined forage grass up along the filter plate. Some impurities mixed in the forage grass and parts that do not meet the size requirements will pass through the filter plate and fall into the waste trough connected to the bottom of the box body, thereby completing the secondary screening of the forage grass.

[0030] As Figures 1 to 6 shown, the present invention provides a forage cutting device for livestock husbandry processing, including a box body 2 and a top cover 1. A control component is arranged at the top end of the top cover 1. The control component includes a pair of material retaining plates 38 hinged to the top end of the top cover 1. One end of each of the two material retaining plates 38 is coaxially connected with a swing arm 8. The free end of the swing arm 8 is hinged with a connecting block 13. A sliding rod 9 is arranged between the two connecting blocks 13. End plates 10 are arranged at both ends of the sliding rod 9. The bottom end of the sliding rod 9 is connected with a moving plate 11. A linkage component is arranged at the bottom end of the moving plate 11. A cutting component is arranged inside the box body 2.

[0031] As Figure 1 , Figure 3 and Figure 6 shown, a retaining frame 12 is arranged on the outer side of the box body 2. The moving plate 11 is slidably clamped inside the retaining frame 12. The linkage component includes a fixed cylinder 14 fixedly connected to the outer side of the box body 2. A swing frame 28 is hinged to the bottom end of the moving plate 11. The free end of the swing frame 28 is rotatably connected with a sliding plate 29. The sliding plate 29 is slidably clamped inside the fixed cylinder 14. A first impeller 30 is rotatably clamped at the bottom end of the fixed cylinder 14. The swing frame 28 is hinged to the retaining frame 12.

[0032] As Figure 1 , Figure 4 and Figure 6 shown, the cutting component includes a motor 15 arranged on the outer side of the box body 2. A pair of first pulleys 16 are coaxially connected to the output shaft end of the motor 15. Any one of the first pulleys 16 is connected with a second pulley 20 through a transmission belt. The second pulley 20 is coaxially connected with a rotating frame 31.

[0033] As Figure 6As shown, a plurality of cross bars 33 are hinged on the rotary frame 31, and a plurality of cutting wheels 34 are coaxially connected to the cross bars 33, and each cutting wheel 34 is arranged at equal intervals.

[0034] As Figure 1 and Figure 6 shown, a fixed rod 36 coaxially arranged with the second pulley 20 is connected inside the box body 2, a plurality of card slots 35 are formed on the fixed rod 36, a fourth pulley 32 equal in number to the card slots 35 is coaxially connected to the cross bar 33, and any one of the fourth pulleys 32 on each cross bar 33 is connected to a card slot 35 through a conveyor belt.

[0035] As Figure 1 , Figure 4 and Figure 6 shown, a motor 15 arranged outside the box body 2 is coaxially connected to a rotating shaft 17, a first bevel gear 19 is coaxially arranged at the output shaft end of the rotating shaft 17, a connecting rod 23 is rotatably connected to the box body 2, second bevel gears 18 are coaxially connected to both ends of the connecting rod 23, any one of the second bevel gears 18 meshes with the first bevel gear 19, and a third bevel gear 22 is coaxially connected to the bottom end of the first impeller 30, and the third bevel gear 22 meshes with the other second bevel gear 18.

[0036] As Figure 1 , Figure 2 , Figure 5 and Figure 6 shown, a support plate 37 is fixedly arranged inside the box body 2, a plurality of longitudinal grooves are formed on the support plate 37, a screening frame 4 is connected to the bottom end of the box body 2, a filter plate 26 is obliquely arranged at the bottom end of the screening frame 4, and the filter plate 26 and the support plate 37 are aligned in the vertical direction.

[0037] The cutting assembly can cut the forage grass entering the box body 2. When the output shaft of the motor 15 rotates, a first pulley 16 coaxially connected to the output shaft thereof will drive the second pulley 20 connected thereto through a conveyor belt to rotate. At this time, the rotary frame 31 coaxially connected to the second pulley 20 will rotate together with the cross bar 33 hinged thereon. Since the fixed rod 36 arranged inside the box body 2 is connected to the fourth pulley 32 coaxially connected to the cross bar 33 through the card slot 35 and the belt, during the process of the rotary frame 31 driving the cross bar 33 to rotate, the cross bar 33 will also rotate self - and cause the cutting wheel 34 coaxially connected to the cross bar 33 to cut the forage grass entering the box body 2. After the forage grass is cut, it will fall into the screening frame 4 through the longitudinal grooves formed on the support plate 37 for secondary screening.

[0038] As Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, a feed chute 25 is connected to the higher end of the filter plate 26, a waste chute 27 is connected to the bottom end of the box body 2, the waste chute 27 is aligned with the filter plate 26 in the vertical direction, a collection box 5 is arranged at the bottom end outlet of the feed chute 25, a third pulley 24 is hinged to the lower end of the filter plate 26, the third pulley 24 is coaxially connected to a second impeller 21, and the third pulley 24 is connected to another first pulley 16 through a transmission belt.

[0039] The filter plate 26 can perform secondary screening on the forage grass entering the screening frame 4. When the motor 15 rotates, another first pulley 16 coaxially connected to its output shaft will drive the third pulley 24 coaxially connected to the second impeller 21 to rotate. The second impeller 21 will rotate and generate wind to blow the inclined forage grass to move upward along the filter plate 26. Some impurities mixed in the forage grass and parts with unqualified sizes will fall through the filter plate 26 into the waste chute 27 connected to the bottom end of the box body 2, and finally the secondary screening of the forage grass is completed.

[0040] As Figure 1 、 Figure 2 and Figure 5 As shown in

[0041] As Figure 1 and Figure 4 As shown, an arc-shaped baffle 6 is horizontally clamped at the top end of the top cover 1. The height of the arc-shaped baffle 6 is higher than that of the baffle plate 38. The arc-shaped baffle 6 protrudes upward. One side of the arc-shaped baffle 6 is connected to a telescopic rod 7, and the telescopic rod 7 is fixedly arranged outside the box body 2.

[0042] Specific usage method and function of this embodiment:

[0043] The control component set in the present invention can dynamically adjust the amount of forage grass processed by the cutting component in the box body 2, prevent the cutting effect from weakening due to too much forage grass entering at one time, and at the same time exacerbate the problem of tool wear. Before using the control component, first send the forage grass to be cut to the top end of the top cover 1 through the conveyor belt arranged on the guide plate 3, and then the forage grass will fall into the box body 2 through the opening provided at the top end of the top cover 1. At the same time, to avoid tool wear deviation caused by uneven distribution of forage grass, it is necessary to drive the telescopic rod 7 to expand and contract to drive the arc-shaped baffle 6 to reciprocate along the top end of the top cover 1, so as to adjust the overall distribution of the forage grass along the cutting component and help the tool wear evenly;

[0044] Before the forage enters the box body 2, start the motor 15 to drive the rotation of the rotating shaft 17. The first bevel gear 19 coaxially connected to the rotating shaft 17 will drive the second bevel gear 18 meshing with it to rotate, causing the connecting rod 23 where the second bevel gear 18 is located to rotate. During the rotation of the connecting rod 23, another second bevel gear 18 connected to its free end will drive the third bevel gear 22 coaxially connected to the bottom end of the first impeller 30 to rotate. At this time, the first impeller 30 rotates and generates wind power at the bottom end of the fixed cylinder 14. The sliding plate 29 slidably clamped in the fixed cylinder 14 will move upward. At the same time, the swing frame 28 hinged to the sliding plate 29 will rotate along the retaining frame 12. The moving plate 11 hinged to the free end of the swing frame 28 will pull the sliding rod 9 downward. The two connecting blocks 13 penetrated by the sliding rod 9 will drive the swing arm 8 where they are located to rotate, and then the baffle plate coaxially connected to the swing arm 8 will deflect downward, thereby opening the opening at the top end of the top cover 1 and allowing the forage to fall into the box body 2. When the cutting assembly is overloaded, the rotational speed of the output shaft of the motor 15 decreases, resulting in a decrease in the wind power generated by the first impeller 30. Furthermore, the angle of downward deflection of the baffle plate is reduced, and finally the size of the opening at the top end of the top cover 1 is reduced, thereby reducing the amount of forage entering and realizing the dynamic control of the forage processing amount.

[0045] The above are only embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to explain the content of the claims.
