Description

Technical Field

[0001] This utility model relates to the field of cattle breeding technology, and in particular to an adjustable hay chopping device for cattle breeding. Background Technology

[0002] A straw chopper is an agricultural machine used to cut and crush crop stalks, forage, and other materials. Its main function is to use sharp blades and a precise mechanical structure to cut straw, forage, and other materials into uniform pieces to meet the feed needs of livestock farming.

[0003] In large-scale cattle farms, the physical requirements of feed vary significantly among herds at different growth stages: calves require finely cut feed (5-8mm) to promote digestion, fattening cattle prefer medium-length feed (10-12mm) to increase feed intake, while adult cattle can adapt to longer feed (15mm). Traditional forage cutters are difficult to adjust cutting parameters quickly and are mostly unidirectional feed feeds, resulting in insufficient operational flexibility within the cattle shed. Furthermore, the widespread use of silage requires equipment capable of handling high-moisture, high-fiber materials, posing greater challenges to blade wear resistance and cutting efficiency.

[0004] Therefore, we propose an adjustable hay chopping device for cattle. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable hay chopping device for cattle farming.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable hay chopping device for cattle includes a base with four casters movably mounted on its lower surface. Four fixing blocks are fixedly mounted on both sides of the base, and threaded rods are threadedly connected inside the fixing blocks. A handle is fixedly mounted on one side of the top of the threaded rod, and an anti-slip block is fixedly mounted on the bottom of the threaded rod. A rectangular groove is formed on the upper surface of the base, and a hay chopping component is movably mounted above the groove. A support platform is rotatably connected to one side of the base via a pivot, and a drive component is mounted on the upper surface of the support platform.

[0007] As a further embodiment of this utility model: the grass-cutting assembly includes a sleeve, the sleeve is fixedly installed on the upper surface of the support platform, a turntable is rotatably connected to one side of the sleeve, a groove is opened on the side of the turntable away from the sleeve, a threaded screw is rotatably connected inside the groove, and a knob is rotatably connected to the upper surface of the turntable, the knob is fixedly connected to the threaded screw.

[0008] As a further embodiment of this utility model: the threaded screw is externally threaded with a movable block, the movable block is slidably connected to a slide groove, the movable block is rotatably connected to an adjusting rod on the side away from the turntable, the adjusting rod is rotatably connected to a crossbar on the end away from the movable block, and a plurality of blades are fixedly installed on the lower surface of the crossbar, the blades being triangular.

[0009] As a further embodiment of this utility model: a slide rail is slidably connected inside the crossbar, and a blade back is fixedly installed on the side of the slide rail away from the crossbar. The end of the blade back near the turntable is fixedly connected to the sleeve. Several blades two are fixedly installed on the lower surface of the blade back. The blades two are triangular and are arranged parallel to the blade one. A handle is fixedly installed on the end of the blade back away from the sleeve.

[0010] As a further embodiment of this utility model: the drive assembly includes an inclined plate, the upper surface of the support platform is fixed with the inclined plate, the inclined plate is at a 45-degree angle, the upper surface of the inclined plate is fixedly mounted with a motor by bolts, a small synchronous pulley is fixedly mounted on one side of the motor by a coupling, the small synchronous pulley is externally frictionally connected to a synchronous belt, and the end of the synchronous belt away from the small synchronous pulley is internally frictionally connected to a large synchronous pulley.

[0011] As a further embodiment of this utility model: a spindle is rotatably connected inside the sleeve, one end of the spindle is fixedly connected to the turntable, and the end of the spindle away from the turntable is fixedly connected to the large synchronous pulley.

[0012] Compared with the prior art, this utility model provides an adjustable hay chopping device for cattle feeding, which has the following beneficial effects: This invention utilizes the coordinated action of a turntable, a threaded screw, and a movable block to precisely control the blade spacing. When the user rotates the knob, the threaded screw drives the movable block to slide within the groove, which in turn moves the adjusting rod along the slide rail, thus adjusting the spacing between blade one and blade two (5-15cm continuously adjustable). This design breaks through the limitations of fixed spacing in traditional chaff cutters, allowing for customized cutting lengths based on the age of the cattle (calves, fattening cattle, adult cattle) and the type of feed (silage corn, alfalfa hay, straw). The staggered arrangement of the triangular blades creates shearing force, increasing efficiency by 30% compared to traditional flat blade designs, and producing a clean cut that reduces nutrient loss. Combined with the rotating platform, it enables multi-angle feeding, adapting to different site layouts and operating habits.

[0013] This invention features a motor mounted on a 45-degree inclined plate, creating a unique power transmission path: the motor drives a small synchronous pulley via a coupling, which in turn drives a large synchronous pulley via a synchronous belt (transmission ratio 1:3), ultimately driving the spindle and turntable to rotate. This design lowers the motor's center of gravity, reduces vibration by 40% during operation, and lowers noise to below 65 decibels, meeting the environmental protection requirements of livestock farms. Compared to chain drives, synchronous belt drives require no lubrication and extend the maintenance cycle to 500 hours, reducing operating costs. Regarding the support structure, the universal wheels and threaded rod anti-slip blocks of the base form a dynamic balance: during movement, the universal wheels quickly position the device; during operation, rotating the handle brings the anti-slip blocks into contact with the ground. Testing has shown that it can withstand 800N of lateral force without displacement, ensuring stability during high-speed cutting. The shaft between the support platform and the base uses a ball bearing design, with a rotational torque of less than 5N·m, allowing a single person to easily adjust the cutting direction.

[0014] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0020] like Figures 1-4 As shown, the chaff-cutting assembly 8 includes a sleeve 12. The sleeve 12 is fixedly installed on the upper surface of the support 10. A turntable 13 is rotatably connected to one side of the sleeve 12. A groove 14 is formed on the side of the turntable 13 away from the sleeve 12.

[0022] Working principle: First, connect the device to the power supply of the cattle farm. Rotate the threaded screw 15 on the fixed block 3 to lower the anti-slip blocks 6 one by one. After the motor 26 starts, the power is amplified by the synchronous pulley group to drive the turntable 13 to rotate. The threaded screw 15 on the turntable 13 adjusts the position of the movable block 17 with the knob 16 to determine the blade spacing and fine-tune the cutting spacing to complete the preparation of feed of different specifications. The hay to be chopped is placed between the first blade 20 and the second blade 23. The rotation of the turntable 13 drives the adjusting rod 18 to reciprocate, so that the crossbar 19 makes a straight cutting action along the slide rail 21.
