Description

Technical Field

[0001] This utility model belongs to the field of fertilization technology, and in particular to a device for applying biochar in tobacco fields. Background Technology

[0002] Tobacco leaves are annual or short-lived perennial herbs belonging to the Solanaceae family. The petioles are inconspicuous or winged. Tobacco leaves are the raw material for the tobacco industry. Tobacco fields are the land where tobacco leaves are grown. Before planting, biochar is applied to the tobacco fields in holes to improve the subsequent growth of the seedlings. However, the planting spacing varies depending on the tobacco variety, and traditional hole-applying devices are mostly fixed, with limited adjustment for lateral spacing.

[0003] A search revealed a Chinese patent document (application publication number CN113557824A) entitled "A Quantitative Hole Application Device for Biochar-Based Fertilizer." This device comprises: an integrated machine with a fertilization mechanism rotatably connected internally; a sowing mechanism slidably connected internally to the integrated machine; a linkage component rotatably connected externally to both the fertilization and sowing mechanisms; and an adjustment mechanism rotatably connected to the linkage component. This device effectively ensures quantitative fertilization of crops and allows for simultaneous sowing and fertilization, improving the overall applicability and efficiency of the equipment. By adjusting the diameter of the variable-speed wheel through the adjustment mechanism, the transmission ratio of the linkage component can be changed, allowing for adjustments to the sowing spacing and fertilizer application rate based on the crop type. Tobacco fields are fields where tobacco leaves are grown. Before planting, biochar hole application is necessary to improve the subsequent growth of tobacco seedlings. However, different tobacco varieties require different planting spacings, and traditional hole application devices are mostly fixed, with limited lateral spacing adjustment. Utility Model Content

[0037] Please see Figures 1 to 4 As shown, a device for applying biochar in tobacco fields is provided in this embodiment, which includes:

[0038] Vehicle body 1;

[0039] A horizontal support plate 2 is fixedly connected to the lower part of the vehicle body 1. An assembly frame 3 is provided below the horizontal support plate 2. Multiple hydraulic cylinders 4 are embedded in the top of the horizontal support plate 2. The piston parts of the multiple hydraulic cylinders 4 are connected and fixed to the assembly frame 3. Two movable plates 5 are provided in the inner cavity of the assembly frame 3. Multiple movable frames 6 are provided on the outer periphery of the two movable plates 5. Multiple threaded holes are opened on the side of the movable plates 5. Some of the threaded holes are threadedly connected to limit threaded rods 15. The sides of the assembly frame 3 and the movable frames 6 are provided with auxiliary holes for the limit threaded rods 15 to pass through. Protective shells 7 are installed at the bottom of the assembly frame 3 and the movable frames 6. The distance between the movable plates 5 and the assembly frame 3 is adjusted in advance according to the needs of the hole construction. Then the number and position of the movable frames 6 are changed, thereby changing the distance between the multiple drill rods 9 and fixing them with the limit threaded rods 15.

[0040] The inner cavity of the protective shell 7 is equipped with a forward and reverse motor 8. The outer periphery of the protective shell 7 is rotatably connected to an inspection door. The inspection door is connected to the protective shell 7 by a latch. The side of the inspection door is provided with a heat dissipation channel and other necessary equipment. The output shaft of the forward and reverse motor 8 passes through the protective shell 7 and is connected to a drill rod 9 for drilling holes. It pushes the push-pull rod 108 and the wheel 104 to move. After moving to the designated position, the controller turns on the forward and reverse motor 8. The forward and reverse motor 8 drives the drill rod 9 to rotate, controls the hydraulic cylinder 4 to extend, drives the assembly frame 3 to move down, and indirectly drives the drill rod 9 to move down. The rotating drill rod 9 can drill the field below. After reaching the designated depth, the hydraulic cylinder 4 is reset, the drill rod 9 moves up, and thus drills a hole.

[0041] The storage tank 10 is detachably connected to the top of the vehicle body 1. The height of the storage tank 10 relative to the discharge pipe 13 is adjusted according to actual needs to ensure smooth discharge. It is used to store biochar fertilizer for tobacco field application. The bottom of the storage tank 10 is connected to multiple discharge pipes equipped with solenoid valves. The discharge pipes are connected to an inclined discharge pipe 13 through a corrugated pipe 12. The height of the discharge pipe 13 is lower than that of the discharge pipe to ensure that the biochar fertilizer falls with gravity. The outer periphery of the protective shell 7 is connected to an auxiliary inclined plate 14 for connection with the discharge pipe 13. The opening direction can be adjusted, or the discharge pipe 13 can be a corrugated pipe. Adjust the opening position of the discharge pipe 13 and change the distance between the drill rod 9 and the discharge position of the discharge pipe 13. If it cannot be adjusted, the discharge operation can be performed when the discharge pipe 13 moves to the hole position. Continue to push the push-pull rod 108 and the wheel 104 to move. Move a specified distance and repeat the previous hole application operation. At this time, open the solenoid valve of the discharge pipe. The biochar fertilizer falls from the discharge pipe 13 into the previous hole by gravity to realize hole application. Then repeat this operation.

[0042] Vehicle body 1 includes:

[0043] Two hollow boards 101;

[0044] Both C-shaped adjustment plates 102 are inserted into the inner cavities of the two hollow plates 101;

[0045] Four support legs 103 are connected to the bottom ends of two adjusting plates 102 respectively. Wheels 104 are installed on the sides of the support legs 103. Four threaded channels are opened at the top of the hollow plate 101, and each of the four threaded channels is threadedly connected to a fixing threaded rod 105. Multiple round holes for the fixing threaded rod 105 to pass through are opened at the top of the two adjusting plates 102. Multiple stabilizing plates 106 connected to the cross support plate 2 are connected between the two hollow plates 101 to change the distance between the adjusting plate 102 and the hollow plate 101. The fixing threaded rod 105 is used to fix the plate and prevent the wheels from stepping on the acupoint.

[0046] The top of each of the two stabilizing plates 106 is connected to a diagonal connecting rod 107, and the two diagonal connecting rods 107 are connected to a push-pull rod 108. A controller for control is installed on the outer periphery of the push-pull rod 108 to facilitate rapid operation and control.

[0047] Hydraulic cylinder 4, forward and reverse motor 8, and solenoid valve are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the problem solved by this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0048] Working principle

[0049] This tobacco biochar application device pre-adjusts the distance between the movable plate 5 and the assembly frame 3 according to the application requirements. Then, it changes the number and position of the movable frames 6, thereby altering the distance between multiple drill rods 9, which are then fixed using limiting threaded rods 15. The distance between the adjusting plate 102 and the hollow plate 101 is changed and fixed using fixing threaded rods 105. Next, the feeding pipe 13 is moved, changing the distance between the drill rods 9 and the feeding position of the feeding pipe 13, thus pushing the push-pull rod 108 and the wheel 104 to move. After moving to the designated position, the controller activates the positive and negative electrical switches. The machine 8, with its forward and reverse motors 8 driving the drill rod 9 to rotate, controls the hydraulic cylinder 4 to extend, causing the assembly frame 3 to move downwards, indirectly causing the drill rod 9 to move downwards. The rotating drill rod 9 can drill into the field below. After reaching the specified depth, the hydraulic cylinder 4 is reset, and the drill rod 9 moves upwards, thus drilling a hole. Then, the push-pull rod 108 and wheel 104 continue to move, moving a specified distance, repeating the previous hole application operation. At this time, the solenoid valve of the discharge pipe is opened, and the biochar fertilizer falls from the discharge pipe 13 into the previous hole under gravity, realizing hole application. Then, this operation is repeated.
