Description

Technical Field

[0001] This utility model relates to the field of mulch film covering machine technology, and in particular to an adjustable mulch film covering machine. Background Technology

[0002] To increase crop yield, in some water-scarce and arid areas, mulch film is often used to raise soil temperature, retain soil moisture, maintain soil structure, prevent pests from attacking crops and diseases caused by certain microorganisms, and promote plant growth. This involves using transparent or PE film to cover and maintain the ground. Therefore, mulch film covering equipment is needed for easy installation.

[0003] However, traditional mulching machines can only cover one ridge at a time, and their large size makes them inconvenient to operate on ridges with narrow spacing, resulting in reduced mulching efficiency and affecting work efficiency. Therefore, further improvements are needed. To this end, we have proposed an adjustable mulching machine. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable mulch film covering machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable mulch film covering machine, comprising a fixed frame, universal wheels uniformly fixedly installed at the bottom end of the fixed frame, a fixed plate uniformly fixedly and movably installed in the middle of the fixed frame, connecting blocks fixedly installed at the left and right ends of the front side of the fixed frame, and fixed blocks fixedly installed at the left and right ends of the rear side of the fixed frame. A mulch film roller is rotatably installed between the fixed blocks. Movable grooves are uniformly opened on the rear side of the fixed frame, and mounting plates are movably installed in the movable grooves. Sliding grooves are opened on the upper and lower sides of the movable grooves. A connecting pipe is fixedly installed in the middle of the mounting plate, and a fixed... The bolt is movably mounted on the upper side of the movable groove. An installation block is fixedly mounted on the upper circumferential surface of the connecting pipe. A stepper motor is fixedly mounted on the upper side of the installation block. A coupling is fixedly mounted on the output shaft of the stepper motor. The stepper motor is fixedly connected to a spiral auger through the coupling. A conveying pipe is threadedly connected to the end of the connecting pipe away from the excavator. A fixing ring is fixedly mounted on the circumferential surface of the end of the conveying pipe away from the connecting pipe. Connecting blocks are symmetrically fixedly mounted on the circumferential surface of the fixing ring. A telescopic rod is rotatably mounted in the middle of the connecting block. A soil pressing roller is fixedly mounted on the output end of the upper telescopic rod, and a pressure film wheel is fixedly mounted on the output end of the lower telescopic rod.

[0006] Furthermore, a soil excavator is fixedly installed at the lower end of the connecting pipe. The right diameter of the soil excavator is larger than the left diameter of the soil excavator. This allows the soil excavator to collect the soil more comprehensively at the bottom of the connecting pipe, thereby making it easier for the auger to transport the soil into the conveying pipe and improving the working efficiency of the auger.

[0007] Furthermore, the connecting pipe is fixedly installed in the middle of the fixing plate; this allows the connecting pipe to provide more stable support for the excavator during the process of the excavator collecting soil, thereby ensuring the working effect of the excavator.

[0008] Furthermore, the sagittal cross-sectional dimensions of the mounting plate are consistent with the sagittal cross-sectional dimensions of the movable groove and the sliding groove; this can reduce the gap between the mounting plate and the movable groove and the sliding groove, thereby allowing the mounting plate to move more stably with the connecting pipe in the movable groove.

[0009] Furthermore, the end of the conveying pipe near the fixed frame is set as an elastic pipe; this can prevent excessive squeezing pressure on the conveying pipe during the process of the telescopic rod carrying the soil pressing roller and the film pressing wheel to cover the mulch film, thereby avoiding damage to the conveying pipe and affecting its use.

[0010] Furthermore, the bottom end of the pressing roller is lower than the bottom end of the pressing roller; this allows the pressing roller to press the mulch film more stably, thereby preventing the mulch film from being pulled out of the soil and affecting the performance.

[0011] The beneficial effects of this utility model are:

[0012] 1. In use, the worker connects the fixing frame to the tractor through the connecting block. As the tractor moves with the fixing frame, the mulch film is laid on the ridges by rotating the mulch film roller. Then, the stepper motor is started to transport the soil from the bottom to the top of the connecting pipe with the spiral auger. At the same time, the lower telescopic rod with the pressing roller presses against the mulch film to press it onto the ground. Then, the soil is transported to the top of the mulch film through the conveying pipe. The soil is then compacted by the upper telescopic rod with the pressing roller, thus stably laying the mulch film on multiple ridges and improving the efficiency of mulch film laying.

[0013] 2. In use, this utility model moves the connecting pipe along the chute via the mounting plate, and then fixes the mounting plate with fixing bolts, thereby adjusting the distance between adjacent connecting pipes. This allows the connecting pipe to carry the conveying pipe to cover different ridges with film, thereby improving the applicability and work efficiency of mulch film covering.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4As shown, an adjustable mulch film covering machine is disclosed, comprising a fixed frame 1, universal wheels 2 uniformly fixedly mounted at the bottom end of the fixed frame 1, a fixed plate 3 uniformly movably mounted at the middle of the fixed frame 1, connecting blocks 4 fixedly mounted at the left and right ends of the front side of the fixed frame 1, fixed blocks 5 fixedly mounted at the left and right ends of the rear side of the fixed frame 1, a mulch film roller 6 rotatably mounted between the fixed blocks 5, movable grooves 7 uniformly opened at the rear side of the fixed frame 1, mounting plates 8 movably mounted in the movable grooves 7, sliding grooves 9 opened on the upper and lower sides of the movable grooves 7, a connecting pipe 10 fixedly mounted at the middle of the mounting plate 8, and a fixing bolt 11 threadedly connected to the upper end of the mounting plate 8 on the side away from the fixed plate 3, the fixing bolt 11 being movably mounted on the upper side of the movable groove 7. An mounting block 12 is fixedly installed on the upper circumferential surface of the connecting pipe 10. A stepper motor 13 is fixedly installed on the upper side of the mounting block 12. A coupling is fixedly installed on the output shaft of the stepper motor 13. A spiral auger 14 is fixedly connected to the stepper motor 13 through the coupling. A conveying pipe 16 is threadedly connected to the end of the connecting pipe 10 away from the excavator 15. A fixing ring 17 is fixedly installed on the circumferential surface of the end of the conveying pipe 16 away from the connecting pipe 10. A connecting block 18 is symmetrically fixedly installed on the circumferential surface of the fixing ring 17. A telescopic rod 19 is rotatably installed in the middle of the connecting block 18. A soil pressing roller 20 is fixedly installed at the output end of the upper telescopic rod 19. A pressure roller 21 is fixedly installed at the output end of the lower telescopic rod 19.

[0023] In this embodiment, the worker connects the fixing frame 1 to the tractor via the connecting block 4. As the tractor moves with the fixing frame 1, the mulch film roller 6 rotates to lay the mulch film on the ridge. The bottom of the connecting pipe 10 then excavates the soil. Simultaneously, the stepper motor 13 is activated, causing the auger 14 to rotate. During the rotation of the auger 14, the soil is transported from the bottom to the top of the connecting pipe 10. At the same time, the lower telescopic rod 19 rotates around the connecting block 18 to adjust the angle between the lower telescopic rod 19 and the conveying pipe 16. The lower telescopic rod 19, along with the pressing roller 21, presses the mulch film against the ground. Then, the soil is transported over the mulch film via the conveying pipe 16. The upper telescopic rod 19, along with the pressing roller 20, compacts the soil, thus stably laying the mulch film on the ridge. Simultaneously, the mounting plate 8 moves the connecting pipe 10 along the chute 9, and the mounting plate 8 is fixed by the fixing bolt 11. This adjusts the distance between adjacent connecting pipes 10, allowing the connecting pipe 10 to carry the conveying pipe 16 to cover different ridges, thereby improving the applicability and efficiency of mulch film covering.

[0024] Specifically, a digger 15 is fixedly installed at the lower end of the connecting pipe 10, and the diameter of the right side of the digger 15 is larger than the diameter of the left side of the digger 15.

[0025] By fixing a digger 15 at the lower end of the connecting pipe 10, the digger 15 can collect the soil more comprehensively at the bottom of the connecting pipe 10, so that the auger 14 can more easily transport the soil into the conveying pipe 16.

[0026] Specifically, the connecting pipe 10 is fixedly installed in the middle of the fixing plate 3;

[0027] By fixing the connecting pipe 10 to the middle of the fixing plate 3, the connecting pipe 10 can more stably support the excavator 15 during the process of the excavator 15 collecting soil.

[0028] Specifically, the sagittal cross-sectional dimensions of the mounting plate 8 are consistent with the sagittal cross-sectional dimensions of the movable groove 7 and the sliding groove 9;

[0029] By making the sagittal cross-sectional dimensions of the mounting plate 8 consistent with those of the movable groove 7 and the sliding groove 9, the gap between the mounting plate 8 and the movable groove 7 and the sliding groove 9 can be reduced, thereby allowing the mounting plate 8 to move more stably with the connecting pipe 10 in the movable groove 7.

[0030] Specifically, the end of the delivery pipe 16 closest to the fixed frame 1 is configured as an elastic pipe;

[0031] By setting one end of the conveying pipe 16 near the fixed frame 1 as an elastic pipe, excessive squeezing pressure can be avoided on the conveying pipe 16 during the process of the telescopic rod 19 covering the mulch film with the soil pressing roller 20 and the film pressing wheel 21.

[0032] Specifically, the bottom end of the pressure roller 21 is lower than the bottom end of the soil pressing roller 20;

[0033] By positioning the bottom of the pressing roller 21 lower than the bottom of the pressing roller 20, the pressing roller 21 can apply more stable pressure to the mulch film.

[0034] Working principle: Workers connect the fixing frame 1 to the tractor via the connecting block 4. As the tractor moves with the fixing frame 1, the mulch film roller 6 rotates to lay the mulch film on the ridge. The bottom of the connecting pipe 10 then excavates the soil. Simultaneously, the stepper motor 13 is activated, causing the auger 14 to rotate. The rotating auger 14 transports the soil from the bottom to the top of the connecting pipe 10. At the same time, the lower telescopic rod 19 rotates around the connecting block 18 to adjust the angle between the lower telescopic rod 19 and the conveying pipe 16. Then, the lower telescopic rod 19, carrying the pressing roller 21, presses the mulch film against the ground. Soil is then transported to the top of the mulch film via the conveying pipe 16. The upper telescopic rod 19, carrying the pressing roller 20, compacts the soil, thus stably laying the mulch film on the ridge. Simultaneously, the mounting plate 8 moves the connecting pipe 10 along the chute 9, and the mounting plate 8 is fixed by the fixing bolt 11. This adjusts the distance between adjacent connecting pipes 10, allowing the connecting pipe 10 to carry the conveying pipe 16 to cover different ridges with film, thereby improving the applicability and work efficiency of mulch film covering.
