DETAILED DESCRIPTION
[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. Embodiment one:
[0031] Please refer to Figures 1-7 The utility model discloses a mulch covering device, including frame 1, film roll installer 2, pre-wheel group 3, adjustable mounting seat 7. And the structure symmetrical setting's first film pressing and soil covering device 4 and second film pressing and soil covering device 5. Film roll installer 2 is connected and is installed in the frame 1 first half. The frame 1 rear half is installed with two pressing rollers 6. The front end and rear end of frame 1 are fixed with two adjustable mounting seats 7 through the nut respectively. The two adjustable mounting seats 7 installed on the front end of frame 1 are installed with a pre-wheel group 3 respectively. The two adjustable mounting seats 7 installed on the rear end of frame 1 are installed with first film pressing and soil covering device 4 and second film pressing and soil covering device 5 respectively.
[0032] Among them, frame 1 includes rectangular frame 11. The two rectangular columns 12 that are fixed to the left and right on the upper end of the first half of rectangular frame 11 are symmetrically. Rectangular clamping groove 13 is set up on the upper end of rectangular column 12. One rope ring 14 is fixed at the two corners of the front end of frame 1 respectively. Two pressing rollers 6 are installed in the rear half of rectangular frame 11. The front wall both ends and the rear wall both ends of rectangular frame 11 are respectively opened with the rectangular through hole 15 that cooperates with adjustable mounting seat 7.
[0033] The film roll mounting device 2 comprises a cylindrical rod 21. Two rectangular clamps 22 are fixed to the two ends of the cylindrical rod 21 respectively. A circular tube 23 is rotatably mounted on the cylindrical rod 21 through a bearing. A sliding sleeve 24 is slidably mounted on the two ends of the circular tube 23 respectively. A jackscrew 25 is threadedly mounted on the sliding sleeve 24. After the device is assembled, the operator first installs a film roll of appropriate width on the film roll mounting device 2. Due to the design of the film roll mounting device 2, it can position film rolls of different diameters through the sliding sleeve 24 and the jackscrew 25, thereby adapting to film of different widths. This feature enables the device to be flexibly used for cultivating angelica on mounds of different widths.
[0034] The adjustable mounting seat 7 comprises a rectangular insertion tube 71. A rectangular sliding block 72 is fixed to one side of the outer wall of the rectangular insertion tube 71 and cooperates with the rectangular through hole 15. A threaded column 73 is fixed to the rectangular sliding block 72 and cooperates with the nut. Two handle bolts 74 are threadedly fixed to the other outer wall of the rectangular insertion tube 71.
[0035] The front wheel set 3 comprises a first rectangular column 31 which cooperates with the rectangular insertion tube 71. A rubber wheel 32 is mounted on the lower end of the first rectangular column 31. The first film pressing and soil covering device 4 comprises a second rectangular column 41 which cooperates with the rectangular insertion tube 71. A film pressing disc 42 is mounted on the lower end of the second rectangular column 41. A horizontal crossbar 43 is fixed to the middle of the second rectangular column 41. A third rectangular column 44 is fixed to the end of the horizontal crossbar 43. A soil turning plate 45 is fixed to the lower end of the third rectangular column 44. The operator adjusts the adjustable mounting seat 7 to change the positions of the front wheel set 3, the first film pressing and soil covering device 4, and the second film pressing and soil covering device 5 according to the width and depth of the angelica mounds. The handle bolts 74 on the adjustable mounting seat 7 allow the operator to accurately adjust the width and depth of the components, ensuring that the device can closely fit mounds of different sizes.
[0036] After the device is ready, the operator can manually pull the device using a rope through the rope ring 14 at the front end of the frame 1, or use a battery car or other towing device to pull the device through the rope. During the covering process, the front wheel set 3 first contacts the ground, guiding the device to travel along the mound. Then, the film is unwound from the film roll mounting device 2 and covers the mound. The two pressing rollers 6 roll in the rear half of the frame 1, helping to expel air under the film and preventing the film from being pulled during unwinding.
[0037] As the device continues to travel, the first film pressing and soil covering device 4 and the second film pressing and soil covering device 5 perform film pressing and soil covering operations on the film covering the mound respectively. The film pressing disc 42 tightly presses the film into the soil, while the soil turning plate 45 covers the soil on the film, ensuring that the film is firmly fixed on the mound.
[0038] The rectangular frame 11 is fixed with a handle rod 16 extending forward and upward at the front end center. During the whole film covering process, the operator can rectify the frame 1 through the handle rod 16 to ensure the device always travels in a straight line, improving the film covering efficiency and quality.
