Description

Technical Field

[0001] This utility model relates to the field of weeding machine technology, specifically to a plum planting weeding machine with built-in protective function. Background Technology

[0002] The field of weeding machinery technology involves the efficient removal of weeds in fields using mechanical equipment to increase crop growing space and farmland yield. In plum cultivation, weeds compete with plum seedlings for water, nutrients, and sunlight, inhibiting plum growth and even becoming a source of pests and diseases, increasing the risk of plum diseases and affecting fruit quality and yield. Therefore, using a plum planting weeding machine with built-in protective features can promptly remove weeds and effectively limit the splashing of weeds, ensuring operator safety and reducing environmental pollution.

[0003] Chinese utility model patent CN220755552U discloses a weed cutter with a grass collection function, which includes "starting an air pump to apply air pressure to the inside of the connecting pipe, thereby sucking the cut grass into the inside of the dust suction hood, and then transporting it into the inside of the collection box under the transport of the connecting pipe to complete the collection of grass"; however, no corresponding protective measures were taken during the cutting and collection of grass, which caused the chopped grass to splash outwards, which could easily cause accidental injury to the operator. The overall installation was poor, and the grass splashing outwards greatly affected the grass collection effect, making it impractical. Utility Model Content

[0004] The purpose of this invention is to provide a plum planting weeding machine with built-in protective function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plum planting and weeding machine with built-in protective function, including a frame. A through groove is formed in the middle of the upper surface of the frame, and a protective cover is fitted inside the through groove. A locking groove is formed in the middle of the top of both sides of the protective cover. A vertical frame is installed at the top of the frame near the through groove. Electric telescopic rods are installed at both ends of the top of the vertical frame. A support plate is installed at the bottom of the electric telescopic rod. A mounting frame is installed at the top of the support plate. A motor is installed at the top of the mounting frame. A rotating rod is driven at the bottom of the motor. A cutting blade holder is locked at the bottom of the rotating rod. Support blocks are installed at both ends of the top of the through groove. A support frame is installed at one end of the support block. A pull rod is slidably connected inside the support frame. A locking block is installed on one side of the pull rod. A limit ring is fitted on the end of the pull rod away from the locking block. A return spring is installed on one side of the limit ring.

[0006] The beneficial effects of this utility model are as follows: by adding a special protective design, the problem of grass debris flying when cutting grass is effectively avoided, ensuring that operators are not at risk of being injured by splashes and ensuring operational safety. At the same time, it provides an easy-to-install and disassemble installation structure for the protective design, which facilitates the subsequent maintenance of the machine, improves the stability and convenience of the equipment, and enhances the safety and working efficiency of the weed cutter.

[0007] To ensure that the locking block can be pushed or pulled by the lever to insert or disengage from the slot, and that misalignment of the locking block does not affect the installation and fixation of the protective cover:

[0008] As a further improvement to the above technical solution: the external dimensions of the card block are consistent with the internal dimensions of the card slot.

[0009] The beneficial effects of this improvement are as follows: With the above settings, after aligning the slots at the top of both sides of the protective cover with the card blocks, releasing the handle allows the pull rod to work with the return spring to push the card blocks to slide and move until the card blocks are smoothly and accurately embedded in the slots.

[0010] To enable the card blocks to automatically and easily insert and detach from the card slot without requiring additional laborious and cumbersome manual disassembly and assembly operations:

[0011] As a further improvement to the above technical solution: a handle is installed on one side of the pull rod, and the locking block forms a pull-out structure with the support frame through the pull rod, and the limiting ring forms a buffer structure with the support frame through the return spring.

[0012] The beneficial effects of this improvement are as follows: With the above settings, pulling the handle outward will cause the pull rod and the locking block to slide and move, which will cause the locking block to disengage from the slot. At the same time, the return spring will be restricted by the limit ring and undergo elastic compression. After the protective cover is maintained, the handle can be released directly, and the elastic force of the return spring can be used to automatically push the locking block to move until it is embedded in the slot.

[0013] To enable a single motor to drive multiple cutting blades simultaneously, allowing for synchronized cutting and weeding of forage, and avoiding additional operating costs:

[0014] As a further improvement to the above technical solution: a pulley is provided at the top of the outer surface of the rotating rod, and a belt is provided inside the pulley, and multiple pulleys and belts are provided.

[0015] The beneficial effects of this improvement are as follows: With the above settings, the starting motor drives the rotating rod, the cutting blade holder, and the pulley to rotate together, driving the belt and other pulleys to perform synchronous transmission operations, thus enabling multiple cutting blade holders to perform cutting and weeding operations simultaneously.

[0016] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0023] Please see Figures 1 to 4 The plum planting and weeding machine with built-in protective function includes a frame 1. A through groove 2 is opened in the middle of the upper surface of the frame 1. A protective cover 3 is fitted inside the through groove 2. A slot 4 is opened in the middle of the top of both sides of the protective cover 3. A stand 5 is installed at the top of the frame 1 near the through groove 2. Electric telescopic rods 6 are installed at both ends of the top of the stand 5. A support plate 7 is installed at the bottom of the electric telescopic rod 6. A mounting frame 8 is installed at the top of the support plate 7. A motor 9 is installed at the top of the mounting frame 8. A rotating rod 10 is driven at the bottom of the motor 9. A cutting blade holder 11 is clamped at the bottom of the rotating rod 10. Support blocks 12 are installed at both ends of the top of the through groove 2. A support frame 13 is installed at one end of the support block 12. A pull rod 14 is slidably connected inside the support frame 13. A locking block 15 is installed on one side of the pull rod 14. A limit ring 16 is fitted on the surface of the pull rod 14 away from the locking block 15. A return spring 17 is installed on one side of the limit ring 16.

[0024] In this embodiment, as Figure 4 As shown, the external dimensions of the card block 15 are consistent with the internal dimensions of the card slot 4.

[0025] In this embodiment, as Figure 4As shown, a handle is installed on one side of the pull rod 14, and the locking block 15 forms a pull-out structure with the support frame 13 through the pull rod 14, and the limiting ring 16 forms a buffer structure with the support frame 13 through the return spring 17.

[0026] In this embodiment, as Figure 3 As shown, a pulley 18 is provided at the top of the outer surface of the rotating rod 10, and a belt 19 is provided inside the pulley 18. Both the pulley 18 and the belt 19 are provided in multiples.

[0027] The plum planting and weeding machine with built-in protective features operates as follows:

[0028] First, the operator pushes the handlebars at the top of the frame 1 to move the frame 1 to the desired weeding position. Then, the electric telescopic rod 6 (model: ANT-26N) is activated, causing the cutting blade holder 11 to descend vertically to the appropriate cutting position. After adjustment, the motor 9 is started, driving the rotating rod 10 and the cutting blade holder 11 to rotate, allowing for weeding operations. During operation, the operator needs to support the frame 1 for cushioning and horizontal movement, ensuring the weeds continuously pass inside the protective cover 3 for sustained cutting. During the cutting operation, any flying weed debris will be contained by the protective cover 3. Effective shielding prevents direct splashing into the external environment and avoids splashing injuries to operators. After weeding is completed, by pulling the handles at both ends, the locking blocks 15 are disengaged from the corresponding slots 4, allowing the protective cover 3 to automatically detach, facilitating subsequent cleaning and maintenance of the inner wall of the cover and the cutting blade holder 11. After the operation is completed, the protective cover 3 is inserted into the through slot 2 until the slots 4 are aligned with the locking blocks 15 at both ends. At this point, the handles are released, and the spring force pushes the locking blocks 15 to automatically embed into the slots 4, enabling rapid maintenance and replacement of the protective cover 3 and the internal cutting blade holder 11.
