Description

Technical Field

[0001] The present invention relates to the technical field of soil loosening and spraying devices, and particularly relates to a soil loosening and spraying device for garden soil improvement. Background Art

[0002] Garden plants should be planted in suitable soil. According to the requirements of garden plants for soil conditions, factors such as soil permeability and fertility should be artificially adjusted and improved to meet the soil conditions required by garden plants, so as to facilitate the growth and development of garden plants according to the expected purpose;

[0003] Most of the existing methods use spraying agents to improve the soil. The agents are usually sprayed on the surface soil. It takes a long time for the agents to flow into the deep soil. The agents remaining outside the soil are easily evaporated by the sun, resulting in waste of the agents. At the same time, the deep soil does not change positions with the surface soil, which easily causes uneven spraying of the agents and affects the soil improvement efficiency. To solve the deficiencies of the existing technology, we propose a soil loosening and spraying device for garden soil improvement. Summary of the Invention

[0028] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0029] A soil loosening and spraying device for garden soil improvement, including a frame 1, a medicine box 11 fixedly connected to the upper surface of the frame 1, and columns 12 arranged at the rear side of the medicine box 11. A plurality of columns 12 are provided, and a spraying mechanism 2 for spraying medicine on the soil is arranged at the top of the columns 12. An activity space 13 is opened in the middle of the columns 12, and a jacking mechanism 5 for destroying the adjacent soil structure is arranged inside the activity space 13. A soil loosening mechanism 7 for turning the soil bidirectionally is arranged at the front side of the bottom of the columns 12.

[0030] As Figure 1 - Figure 2 shown, vehicle tires and corresponding motors are arranged on the frame 1. The user holds the handle on the frame 1 and starts the corresponding motor. With the assistance of the rotation of the vehicle tires, the device performs soil loosening and spraying treatment on the soil, or the frame 1 can be hung behind a tractor for work;

[0031] As Figure 1 - Figure 3 shown, the jacking mechanism 5 includes a first motor 51 fixedly connected to the left side surface of the column 12, and a shaft rod 52 penetrates through a plurality of columns 12 and the left end of the shaft rod is detachably connected to the rotating rod of the first motor 51;

[0032] As Figure 3 - Figure 5 shown, opposite-direction wheels 53 are fixedly connected to the surface of the shaft rod 52 inside the activity space 13. The opposite-direction wheels 53 are symmetrically arranged. The opposite-direction wheel 53 refers to a wheel in which the distance between the outer edge side of the wheel and the center of the wheel gradually increases with the wheel top as the starting point and rotates one circle;

[0033] As Figure 3And Figure 8 As shown in the figure, a first rod 54 is arranged between adjacent counter-rotating wheels 53. A plug rod 56 is fixedly connected to the bottom surface of the first rod 54. On the left and right sides of the top surface of the first rod 54, top columns 57 are fixedly connected. The top columns 57 are symmetrically arranged. The top columns 57 are connected to the front surface of the column 12 through second return springs 58. When at rest, the top columns 57 are in contact with the folding corners at the tops of the counter-rotating wheels 53. At the same time, a sliding groove 55 is formed on the surface of the first rod 54. When the shaft rod 52 penetrates through the moving space 13, it also penetrates through the sliding groove 55, and relative movement can occur between the sliding groove 55 and the shaft rod 52;

[0034] It should be noted that when at rest, the top columns 57 are located at the folding corners at the tops of the counter-rotating wheels 53. When the first motor 51 is started and the shaft rod 52 rotates, the shaft rod 52 drives the counter-rotating wheels 53 to rotate, causing the top columns 57 to move along the outer edge side surfaces of the counter-rotating wheels 53, making the center of the top rod gradually move away from the center of the counter-rotating wheels 53. At the same time, the first rod 54 is pushed to move upward inside the moving space 13, and the second return springs 58 are continuously stretched until the top columns 57 return to the folding corners of the counter-rotating wheels 53 again. The second return springs 58 quickly reset, causing the first rod 54 to drive the bottom tip of the plug rod 56 to suddenly insert into the soil, thereby perforating the soil and destroying the structural stability between the soils, which is beneficial to the subsequent soil loosening treatment.

[0035] As Figure 8 shown, the top of the first rod 54 is open and the inside is a cavity. A support column 6 is slidably connected inside the first rod 54. It should be noted that when the first rod 54 moves upward or downward, it moves along the support column 6. The arrangement of the support column 6 facilitates improving the stability of the movement of the first rod 54;

[0036] As Figure 8 shown, the sliding groove 55 penetrates through the first rod 54 and the support column 6, enabling the shaft rod 52 to also move relative to the sliding groove 55 on the support column 6. Buffer pads 61 are detachably connected to the top and bottom surfaces of the sliding groove 55 inside the support column 6. The buffer pads 61 are made of elastic materials, such as rubber or sponge, etc., to slow down the impact force when the shaft rod 52 comes into contact with the top and bottom surfaces of the sliding groove 55; the top surface of the support column 6 is fixedly connected to the bottom surface of the cylinder body 22, and the support column 6 is suspended inside the column 12 through the cylinder body 22.

[0037] As Figure 3 - Figure 6 shown, the spraying mechanism 2 includes a first groove 21 opened at the top of the moving space 13. Both the top and bottom of the first groove 21 are open and the first groove 21 is communicated with the moving space 13. A cylinder body 22 is fixedly connected inside the first groove 21. The inside of the cylinder body 22 is a cavity and the top is open. A water pipe 23 is arranged at the bottom inside the cylinder body 22. The end of the water pipe 23 penetrates through the column 12 and is detachably connected to the liquid outlet of the medicine box 11;

[0038] As Figure 4 And Figure 6As shown, a pressing component 24 is provided at the top of the cylinder body 22. The pressing component 24 includes a pressing rod and a pressing plate. Pressing channels are formed inside both the pressing rod and the pressing plate, and the two pressing channels are connected. A moving device 4 is arranged on the side of the pressing plate, and the moving device 4 is used to drive the pressing component 24 to move;

[0039] As Figure 4 - Figure 6 shown, a hose 25 is fixedly connected to the bottom surface of the pressing component 24. An infusion component 26 is arranged inside the column 12 below the hose 25. The infusion component 26 includes an infusion channel and a pipe. The pipe is located between adjacent idler wheels 53 in different directions and is used to connect the infusion channel. A plurality of branch channels are arranged at the end of the infusion channel, and the end of each branch channel is fitted with a nozzle on the spraying plate 27. The nozzle can be of an atomizing type, and the medicament can be evenly in contact with the loosened soil without making the soil wet and clumped;

[0040] As Figure 6 shown, one end of the hose 25 is connected to the port at the end of the pressing channel of the pressing plate, and the other end of the hose 25 is connected to the beginning of the infusion channel. An extrusion device 3 is arranged inside the cylinder body 22, and the extrusion device 3 is used to drive the flow of the liquid medicine; it should be noted that the moving device 4 drives the pressing component 24 to move up and down, so that the pressing plate pushes the bottom of the pressing rod to move up and down inside the cylinder body 22. At the same time, the extrusion device 3 flows the medicament in the medicine box 11 into the cylinder body 22 through the water pipe 23. With the cooperation of the moving device 4, the medicament in the cylinder body 22 flows into the hose 25 through the pressing channel, then flows into the infusion channel along the hose 25, and finally flows to the nozzle through the branch channel, so that the spraying plate 27 sprays medicine on the loosened soil;

[0041] As Figure 6 shown, the extrusion device 3 includes a water pump 31 detachably connected inside the cylinder body 22. The water pump 31 is set to be controllable. Each time the moving device 4 drives the pressing component 24 to move downward, the water pump 31 is started, and the water pump 31 can pump the medicament in the medicine box 11 into the cylinder body 22; a flow limiting hole 33 is arranged in the pressing channel inside the pressing rod, and a first ball 34 is arranged above the flow limiting hole 33. When the pressing rod moves downward, the first ball 34 is separated from the flow limiting hole 33, so that the pressing channel is connected to the inside of the cylinder body 22. On the contrary, if the pressing rod moves upward, the first ball 34 coincides with the flow limiting hole 33, and the pressing channel is isolated from the inside of the cylinder body 22, so as to achieve the effect of controlling the flow of the medicament;

[0042] As Figure 4 - Figure 6As shown, a first return spring 32 is provided between the water pump 31 and the bottom of the pressing rod. The moving device 4 includes a first driving wheel 41 on the surface of a shaft rod 52 fixedly connected to the left side of the column 12. The second driving wheel 42 is rotatably connected to the surface of the column 12 and is located above the first driving wheel 41. The first driving wheel 41 and the second driving wheel 42 are connected by a belt, so the second driving wheel 42 moves synchronously with the shaft rod 52;

[0043] As Figure 4 and Figure 6 shown, a steel wire rope 43 is fixedly connected to the surface of the second driving wheel 42. The tail of the steel wire rope 43 is fixedly connected to the side of the top edge of the pressing assembly 24. When the end of the steel wire rope 43 tends to the lowest point of the second driving wheel 42, the steel wire rope 43 drives the pressing assembly 24 to gradually move downward, and the first return spring 32 is compressed. On the contrary, when the end of the steel wire rope 43 tends to the highest point of the second driving wheel 42, the steel wire rope 43 is slack. Under the action of the first return spring 32, the pressing assembly 24 gradually moves upward, thereby realizing the upward and downward movement of the pressing assembly 24.

[0044] As Figure 3 、 Figure 7 and Figure 9 shown, the soil loosening mechanism 7 includes a mounting frame 71 fixedly connected to the front side of the bottom of the column 12. The front side of the top of the mounting frame 71 is rotatably connected to a rotating rod 72. The end of the rotating rod 72 is detachably connected to the rotating rod of the second motor 73. The second motor 73 can drive the rotating rod 72 to intermittently rotate forward and backward by 180°. Among them, the rotating rods 72 on all the mounting frames 71 are the same;

[0045] As Figure 7 and Figure 9 shown, on the same mounting frame 71, symmetric sector plates 74 are fixedly connected to the surface of the rotating rod 72. A plurality of tooth grooves are provided on the bottom surface of the sector plate 74. A support rod 76 is rotatably connected to the inner side of the bottom of the mounting frame 71. A gear 77 is fixedly connected to the surface of the support rod 76. The gear 77 is engaged with the bottom surface of the sector plate 74. Therefore, the sector plate 74 can drive the gear 77 to rotate through the tooth grooves, so that the gear 77 moves synchronously with the rotating rod 72. At the same time, a second soil turning plate 78 is fixedly connected to the left side of the gear 77 on the surface of the support rod 76. Therefore, the gear 77 can drive the second soil turning plate 78 to rotate. Among them, two first soil turning plates 75 are provided between the two sector plates 74. The top of the first soil turning plate 75 is rotatably connected to the inner side of the mounting frame 71 and sleeved on the surface of the rotating rod 72. A rotating device 8 is provided at the bottom of the first soil turning plate 75 on the right side of the gear 77. The rotating device 8 can drive the first soil turning plate 75 to rotate, and the rotation direction is opposite to that of the second soil turning plate 78. Therefore, the adjacent first soil turning plates 75 and the second soil turning plates 78 can break up the agglomerated soil in a rubbing form, which is beneficial to improving the soil loosening efficiency;

[0046] As Figure 9As shown in the figure, the rotating device 8 includes a limiting groove 81 formed on the surface of the first soil-turning plate 75. A connecting rod 82 is slidably connected inside the limiting groove 81. Convex rods 83 are fixedly connected to both the left and right ends of the connecting rod 82. The tail of the convex rod 83 is fixedly connected to the edge of the disc 84. The disc 84 is fixedly connected to the surface of the support rod 76. There are two discs 84, which are symmetrically arranged on the left and right sides of the first soil-turning plate 75. It should be noted that the second soil-turning plate 78 and the disc 84 are respectively arranged on the left and right sides of the gear 77. Taking the center of the gear 77 as the starting point, the head of the second soil-turning plate 78 is symmetric and opposite to the head of the convex rod 83. Therefore, when the second soil-turning plate 78 rotates forward, the convex rod 83 squeezes the inside of the limiting groove 81 through the connecting rod 82, thereby pushing the first soil-turning plate 75 to rotate in the opposite direction, so that the first soil-turning plate 75 and the second soil-turning plate 78 rotate in opposite directions.

[0047] It should be noted that the present invention is a soil loosening and spraying device for garden soil improvement. When in use, as Figure 1 - Figure 9 shown, the frame 1 is moved manually or by a device such as a tractor. The first motor 51 drives the differential wheel 53 to rotate through the shaft rod 52. With the cooperation of the first return spring 32, the differential wheel 53 pushes the first rod 54 to move up and down through the top column 57, so that the first rod 54 makes holes in the soil through the inserting rod 56, destroying the structure between the soils. Then the second motor 73 drives the sector plate 74 to rotate through the rotating rod 72. The sector plate 74 drives the second soil-turning plate 78 to rotate through the gear 77. At the same time, the gear 77 drives the rotating device 8 to drive the first soil-turning plate 75 to rotate, and the first soil-turning plate 75 and the second soil-turning plate 78 rotate in opposite directions, so that the first soil-turning plate 75 and the second soil-turning plate 78 loosen the soil, facilitating the exchange of positions between the deep soil and the surface soil. At the same time, the shaft rod 52 drives the pressing assembly 24 to move up and down through the moving device 4, and the squeezing device 3 flows the medicament in the medicine box 11 into the cylinder 22 through the water pipe 23. With the cooperation of the moving device 4, the medicament in the cylinder 22 flows into the hose 25 through the pressing channel, then flows into the infusion channel along the hose 25, and finally flows to the nozzle through the branch channel, so that the spraying plate 27 sprays the loosened soil with the medicament.
