Description

Technical Field

[0002] The integrated equipment for water-retaining agent for afforestation, fertilizing, sowing, and film mulching is an agricultural machine integrating the functions of water retention, fertilization, and film mulching. Through mechanized operation, it can accurately apply water-retaining agents and fertilizers and simultaneously complete plastic film covering. Its core significance lies in improving the efficiency and sustainability of afforestation. This technology combines mechanization with environmental protection materials to assist in ecological restoration and efficient agriculture, achieving a win-win situation of economic and ecological benefits.

[0003] In the existing integrated equipment for water-retaining agent for afforestation, fertilizing, sowing, and film mulching, during actual use, when performing film mulching, the edge of the film is pressed against the soil to achieve the film mulching effect. However, during this process, the edge of the film is extremely prone to tearing, which in turn leads to the failure of film mulching, resulting in serious loss of soil moisture and nutrients. At the same time, it is not conducive to the heat preservation of plants. When encountering strong wind weather, the airflow will also carry the film, causing the film to roll up and other situations, resulting in problems such as the failure of film mulching.

[0004] Therefore, an integrated equipment for water-retaining agent for afforestation, fertilizing, sowing, and film mulching is proposed to address the above problems. Summary of the Invention

The present invention provides an integrated device for afforestation water retention agent, fertilization spreading and film mulching. Through the action of the film mulching structure, the special structure of the single-sided inclined shovel makes the soil dug out of the groove located on both sides of the device. Then, during the operation of the device, the film mulching wheel presses the film of the film roll towards the groove. Then, the first soil covering plate covers the soil shoveled by the single-sided inclined shovel back into the groove, thereby achieving the effect of burying the edge of the film, thereby improving the wind resistance of the film mulching, and the soil pressing on the edge of the film can further improve the film mulching effect and the anti-interference ability of the film.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] The following gives specific embodiments.

[0023] Please refer to Figure 1 - Figure 8The present invention provides a technical solution: an integrated device for afforestation water-retaining agent, fertilizer spreading and film covering, comprising a base 1, the top of the base 1 is fixedly connected with a connecting frame 2, a seeding box 3 and a water and fertilizer box 4, the bottom of the base 1 is fixedly installed with a film covering structure 6, an auxiliary structure 7 and a feeding structure 8, the middle part of the auxiliary structure 7 is movably installed with the middle part of the film roll 5, the film covering structure 6 comprises a bottom frame 1 61 fixedly connected to the bottom end of the base 1, a trenching shovel 62 is fixedly connected to the middle part of the bottom end of the bottom frame 1 61, a single-sided oblique shovel 63 is fixedly connected to the two ends of the bottom of the bottom of the bottom frame 1, and a bottom frame 2 6 is fixedly connected to the bottom end of the base 1 away from the bottom frame 1 61. 4. The bottom end of the base frame 64 is rotatably connected to two film covering wheels 65, and the middle part of the bottom end of the base frame 64 is symmetrically fixedly connected to two soil covering plates 66. The single-sided inclined shovel 63 is similar to the single-sided rolling structure of the plowing shovel, so that the soil from the grooves is located on both sides of the equipment. Then, during the operation of the equipment, the film covering wheel 65 presses the film of the film roll 5 into the groove, and then the soil covering plate 66 re-covers the soil shoveled by the single-sided inclined shovel 63 in the groove, thereby burying the edge of the film, thereby improving the wind resistance of the film, and the soil is pressed on the edge of the film, which can further improve the film covering effect and improve the anti-interference ability of the film.

[0024] like Figure 3 As shown, the base frame 64 is slidably connected to a position away from the coating wheel 65 with two round rods 67 that penetrate the base frame 64, the bottom ends of the two round rods 67 are fixedly connected to a bottom plate 68, the bottom end of the bottom plate 68 is fixedly connected to two pressure wheels 69, the top ends of the two round rods 67 are fixedly connected to a top plate 611, the outsides of the top ends of the two round rods 67 are both sleeved with springs 610, the two ends of the two springs 610 are respectively fixedly connected to the bottom end of the top plate 611 and the top of the base frame 64, and the pressure wheels 69 are always pressed on the soil on the top of the film under the pulling force of the springs 610, thereby compacting the soil, improving the fixing effect of the soil on the film, and at the same time, improving the stability of the soil itself to avoid problems such as soil loss.

[0025] like Figure 3 As shown, the bottom end of the top plate 611 is rotatably connected to a rotating clamping rod 612, and a clamping groove 613 is provided at the top of the bottom frame 64. The inner wall of the clamping groove 613 is clamped with the bottom of the rotating clamping rod 612. The top plate 611 is pulled up, and the rotating clamping rod 612 is rotated to be clamped in the clamping groove 613. At this time, the rotating clamping rod 612 remains in a vertical state, thereby lifting the top plate 611, causing the pressure wheel 69 to be lifted and fixed at a high position and separated from the soil surface, thereby facilitating the storage of the pressure wheel 69 and avoiding affecting the film pulling operation during the initial use of the equipment.

[0026] like Figure 4As shown in the figure, the auxiliary structure 7 includes a fixing frame 71 fixedly connected to the middle of the bottom end of the base 1. A winding roller 72 is rotatably connected to the middle of the fixing frame 71. The outer wall of the winding roller 72 is clamped with the inner wall of the film roll 5. A sliding groove 73 is formed on one side of the base 1. A slider 74 is slidably connected inside the sliding groove 73. The bottom end of the slider 74 is fixedly connected with a fixing plate 75. A limiting groove 76 is formed at the bottom of the fixing plate 75. The size and shape of the inner wall of the limiting groove 76 are adapted to the size and shape of one end of the winding roller 72. When a film roll 5 is used up, remove the screws, slide the interactive plate, then take out the used film roll 5 from the outer wall of the winding roller 72, and put on a new one. Then slide the fixing frame 71 and fix it again with screws, so as to realize the rapid replacement of the film roll 5, and thus can effectively improve the operation efficiency of the equipment.

[0027] It should be noted that the slider 74 and the base 1 can be fixed by screws.

[0028] As Figure 5 shown, one end of the winding roller 72 passing through the fixing frame 71 and the axis of a film covering wheel 65 are jointly installed with a first belt pulley group 77. The rotation of the film covering wheel 65 drives the first belt pulley group 77 to rotate, thereby driving the winding roller 72 to rotate, so that the film roll 5 can rotate along with the film covering wheel 65, thus avoiding the film roll 5 being affected by bumps, resulting in excessive film feeding, and being rolled under the film covering wheel 65, resulting in problems such as multi-layer film covering.

[0029] It should be noted that during the continuous unwinding process of the film roll 5, the outer diameter gradually decreases. Therefore, its unwinding speed is not consistent with the film covering speed of the film covering wheel 65 throughout the process. During the initial unwinding process, the unwinding speed is slightly faster than the film covering speed of the film covering wheel 65, while in the later stage, the unwinding speed is slightly slower than the film covering speed of the film covering wheel 65. During the entire film covering operation, the film roll 5 and the film covering wheel 65 are in a dynamic balance state. The excess film released at the initial stage of the film roll 5 will be gradually utilized by the film covering wheel 65 in the later stage. At the same time, the positions of the winding roller 72 and the film roll 5 are relatively high, and the relatively large amount of film released at the initial stage will not drag on the soil surface and be rolled under the film covering wheel 65.

[0030] It should be noted that the first belt pulley group 77, the second belt pulley group 811, and the third belt pulley group 813 are all composed of two toothed belt pulleys and a toothed belt meshing with each other.

[0031] As Figure 5 shown, a protective cover 78 is fixedly installed on the side of the fixing frame 71 away from the fixing plate 75. The first belt pulley group 77 is located inside the protective cover 78. The protective cover 78 can protect the first belt pulley group 77 and the second belt pulley group 811 to prevent the external soil from affecting their normal transmission.

[0032] As Figure 5 and Figure 6As shown in the figure, a third chassis 81 is fixedly connected to the bottom end of the base 1. A second soil covering plate 82 is fixedly connected to the bottom of the third chassis 81. An electromagnetic valve 83 is fixedly installed at the top end of the third chassis 81. A water pipe 84 is installed in the middle of the electromagnetic valve 83. The top end of the water pipe 84 is fixedly connected to the bottom of the water and fertilizer tank 4. The sowing grooves with seeds are re-covered with soil through the second soil covering plate 82. At the same time, the electromagnetic valve 83 is opened, so that the water and fertilizer mixture and the water-retaining agent material inside the water and fertilizer tank 4 can be conveyed to the soil surface through the water pipe 84, thereby realizing the sowing of the water-retaining agent and water and fertilizer.

[0033] As Figure 6 and Figure 7 shown in the figure, a discharge port 85 penetrating the third chassis 81 is opened at the top of the third chassis 81. A support 86 is fixedly connected to the inner wall of the discharge port 85. A transmission rod 87 is rotatably connected to the top of the support 86. A spiral roller 89 is fixedly connected to the top of the transmission rod 87. The top of the spiral roller 89 penetrates into the sowing box 3. A discharge cover 88 is fixedly connected to the top end of the third chassis 81. The transmission rod 87 and the spiral roller 89 are both located inside the discharge cover 88. Feeding through the spiral roller 89 can effectively avoid the problem of blockage during the feeding process of the seed material, and make the feeding more uniform, and the sowing effect is better.

[0034] As Figure 7 shown in the figure, a conical cover 810 is fixedly connected to the outer wall of the transmission rod 87. The conical cover 810 is located between the support 86 and the spiral roller 89. The conical cover 810 can prevent seeds from falling into the meshing part of the toothed belt pulley and the toothed belt in the third belt pulley group 813, thereby affecting the normal use of the third belt pulley group 813.

[0035] As Figure 5 and Figure 8 shown in the figure, a transmission frame is installed at the top of the third chassis 81. A second belt pulley group 811 is jointly installed at one end of the transmission frame and one end of the second belt pulley group 811. A bevel gear group 812 is jointly installed at the end of the transmission frame far from the second belt pulley group 811 and the top end of the third chassis 81. A third belt pulley group 813 is jointly installed at the bottom of the bevel gear group 812 and the bottom of the transmission rod 87. The middle part of the belt pulley group penetrates through the inner and outer sides of the discharge cover 88. Under the transmission effect of the second belt pulley group 811, the bevel gear group 812 and the third belt pulley group 813, the discharge speed of the sowing box 3 matches the running speed of the whole equipment, and the sowing effect of the seed material is further improved.

[0036] Working principle of the present invention: During use, an integrated device for forestation water retention agent, fertilization spreading and film mulching is installed on an agricultural vehicle by using the connecting frame 2. During the movement of the device along with the agricultural vehicle, the trench shovel 62 opens sowing grooves in the soil, thereby facilitating subsequent water and fertilizer spreading and sowing. At the same time, the single-sided inclined shovel 63 reclaims grooves for film mulching. Moreover, the special structure of the single-sided inclined shovel 63 makes the soil excavated from the grooves located on both sides of the device. Then, during the operation of the device, the film mulching wheel 65 presses the film of the film roll 5 towards the grooves. After that, the soil covering plate 66 covers the soil shoveled by the single-sided inclined shovel 63 back into the grooves, thereby achieving the effect of burying the film edges, improving the wind resistance of the film mulching, and the soil pressing on the film edges can further improve the film mulching effect and the anti-interference ability of the film. In addition, under the pulling force of the spring 610, the pressing wheel 69 always presses on the soil on the top of the film, thereby compacting the soil, improving the fixing effect of the soil on the film, and at the same time, improving the stability of the soil itself and avoiding problems such as soil erosion. Pull up the top plate 611 and rotate the rotating latch 612, and then latch it in the card slot 613, so that the pressing wheel 69 can be fixed at a high position, which is convenient for the storage of the pressing wheel 69 and avoids affecting the film pulling operation during the initial use of the device.

[0037] During the normal operation of the device along with the agricultural vehicle, the film mulching wheel 65 rotates normally, thereby driving the first belt pulley group 77 to rotate, driving the winding roller 72 to rotate, and enabling the film roll 5 to rotate along with the film mulching wheel 65, thereby preventing the film roll 5 from being affected by bumps, resulting in excessive film feeding, being rolled under the film mulching wheel 65, and causing problems such as multi-layer film mulching. When a film roll 5 is used up, remove the screws, slide the interactive plate, take out the used film roll 5 from the outer wall of the winding roller 72, and put on a new one. Then slide the fixing frame 71 and fix it again with screws, thereby realizing the rapid replacement of the film roll 5 and can effectively improve the operation efficiency of the device.

[0038] During the operation of the equipment for water-retaining agent, fertilization and film mulching, the pulley set one 77 drives the pulley set two 811 to rotate. Then, through the bevel gear set 812 and the pulley set three 813, the transmission rod 87 is driven to rotate, and then the spiral roller 89 is driven to rotate. Feeding is carried out through the spiral roller 89, which can effectively avoid the problem of blockage during the feeding process of seed materials, and make the feeding more uniform, and the sowing effect is better. At the same time, under the transmission effect of the pulley set two 811, the bevel gear set 812 and the pulley set three 813, the discharging speed of the sowing box 3 matches the running speed of the whole equipment, further improving the sowing effect of the seed materials. After that, the sowing grooves with seeds are re-covered with soil by the soil covering plate two 82. At the same time, the solenoid valve 83 is opened, and then the water-fertilizer mixture and the water-retaining agent material inside the water-fertilizer tank 4 can be transported to the soil surface through the water pipe 84, thus realizing the spreading of the water-retaining agent and water-fertilizer.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
