Description

Technical Field

[0001] The utility model relates to the technical field of agricultural weeding, in particular to a high-efficiency weeding device for agricultural production. Background Art

[0002] Agricultural weeding is an important part of the agricultural production process. Its purpose is to control and eliminate weeds that compete with crops for resources in order to improve crop yield and quality. The current weeding methods are mainly spraying herbicides or manual weeding. The use of chemical herbicides directly kills or causes chronic harm to non-target organisms, seriously damaging the agricultural ecological balance. Manual weeding is labor-intensive, inefficient, and costly. In order to avoid the damage to the agricultural ecological balance caused by chemical herbicides, a flame weeding device has now emerged that can weed by spraying fire.

[0003] However, the flame weeding devices in the prior art can only perform flame weeding at fixed intervals, and cannot adjust the intervals between the flame weeding devices at equal intervals. They cannot adapt to the needs of different crops and field environments, increasing the risk of accidental injury to crops. Especially when crops and weeds are close, they cannot be accurately adjusted according to the actual distribution of weeds, which may result in the flame weeding device being unable to effectively cover all weed areas, thereby reducing the weeding efficiency. Utility Model Content

[0023] The utility model is further described below in conjunction with embodiments.

[0024] Example: Refer to Figures 1 to 4 .

[0025] A highly efficient weeding device for agricultural production comprises an even number of equidistantly distributed flame spraying mechanisms 7, wherein the even number of flame spraying mechanisms 7 are connected to an equidistant regulating mechanism, and the equidistant regulating mechanism can drive the even number of flame spraying mechanisms 7 to be synchronously and equidistantly expanded or retracted.

[0026] The equidistant adjustment mechanism includes a fixed rail 3 and at least one pair of extension rails 301 symmetrically arranged about the fixed rail 3. The fixed rail 3 and the at least one pair of extension rails 301 are connected by a limit adjustment plate 4 through an upper limit sliding connection. There are two limit adjustment plates 4 on the fixed rail 3 and one on the telescopic rail.

[0027] A limiting groove 401 is provided in the limiting adjustment plate 4, and short rods are rotatably connected in the two limiting grooves 401 located at the outermost sides, and a long rod is rotatably connected in the limiting groove 401 located in the middle, and the position where the long rod is rotatably connected to the limiting groove 401 is located in the middle of the long rod, and the two ends of the long rod are rotatably connected to the adjacent long rod or short rod respectively, and the two long rods located in the middle are rotatably connected to the threaded blocks 201.

[0028] The equidistant adjustment mechanism moves forward or backward through the threaded block 201 on the threaded rod 2. When moving forward, it is equidistantly expanded, and when moving backward, it is equidistantly retracted. When the threaded block 201 moves forward on the threaded rod 2, it drives the two rotatably connected long rods to move forward. When the long rod rotates, it drives the limit groove 401 rotatably connected in the middle of the long rod, and drives the short rod rotatably connected to the long rod to extend. At the same time, the limit adjustment plate 4 slidably connected on the fixed rail 3 and the extension rail 301, by rotating the long rod and the short rod on the limit groove 401, the forward expansion of the rotating connecting rod group 6 drives the limit adjustment plate 4 on the extension rail 301 to slide, and at the same time drives the extension rail 301 on it to extend its stroke, thereby achieving the purpose of equidistant adjustment. It should be noted that the equidistant adjustment mechanism is initially in a retracted state.

[0029] The equidistant adjustment mechanism is fixedly connected to the vehicle body 8 through a fixed rod 1, the fixed rod 1 is located at the front end outer wall of the vehicle body 8, a push handle 11 is fixedly connected to the rear end outer wall of the vehicle body 8, a fuel tank 9 is fixedly installed inside the vehicle body 8, a walking mechanism 10 is arranged at the bottom of the vehicle body 8, a motor 5 is fixedly connected to the lower end of the fixed rod 1 near the front side, and a feed port 801 is arranged on the front end outer wall surface of the vehicle body 8.

[0030] The fixing rod 1 is used to be fixedly connected to the vehicle body 8, and the fixing rod 1 is detachably installed. The device is used for agricultural fire spraying and weeding. The vehicle body 8 is driven by manpower through the walking mechanism 10, and can also be driven by replacing it with a tractor fixed connection, and the equidistant adjustment mechanism is fixed by the fixing rod 1.

[0031] refer to Figure 1 and Figure 2 Specifically, the front wall of the fixed rod 1 is fixedly connected to the rear wall of the fixed rail 3, and a motor 5 is arranged at a corresponding position of the lower part of the fixed rod 1.

[0032] Start the motor 5 to rotate forward, and the driving end of the motor 5 drives the threaded rod 2 to rotate. When the threaded block 201 on the threaded rod 2 moves forward in the axial direction of the threaded rod 2, when it is in the expanded state, the spacing of the flamethrower mechanism 7 is expanded, and when it is reversed, it is in the retracted state to reduce the spacing. It should be noted that the motor 5 is started by wireless control, and the forward and reverse rotation of the driving end of the motor 5 can be adjusted wirelessly.

[0033] refer to Figure 3 Specifically, the output end of the motor 5 is fixedly connected to the threaded rod 2, and the outer surface of the threaded rod 2 is threadedly sleeved with a threaded block 201. The front end of the motor 5 is fixedly connected to the rear wall of the fixed rod 1, and the motor 5 can be easily disassembled and installed, which is conducive to the rapid installation of the equidistant adjustment mechanism including (threaded rod 2, fixed rail 3, limit adjustment plate 4, motor 5, rotating connecting rod group 6, etc.) to follow the change drive mode.

[0034] refer to Figure 4 Specifically, a regulating valve 701 is installed at the upper end of the flame-spraying mechanism 7, and a fire-collecting cover 702 is fixedly installed on the outer wall of the flame-spraying mechanism 7.

[0035] The installed regulating valve 701 can open and deliver fuel and adjust the amount of delivered fuel according to the type and density of weeds to be removed. The fire hood 702 has the function of collecting and gathering the sprayed fire, and only sprays fire to remove weeds. It should be noted that a pulse ignition mechanism is installed inside the flame spraying mechanism 7. The regulating valve 701 is a wireless control valve that can control the amount of delivered fuel. This mechanism is an existing device.

[0036] refer to Figure 1 Specifically, the feed port 801 penetrates the outer wall of the fixed rod 1 and is connected to the threaded rod 2 , and the output end of the feed port 801 is connected to the regulating valve 701 on the multi-fire spraying mechanism 7 through a pipeline.

[0037] The fuel is delivered to the flame-spraying mechanism 7 through a pipeline, which facilitates the control of the fuel delivery amount of the regulating valve 701 and avoids waste.

[0038] The working principle of this device is as follows:

[0039] According to the amount of weeding required, a human push cart or a tractor can be selected for connection. The device is driven by human power.

[0040] When weeding a small amount of farmland, a human-powered cart can be used to push it, and a wireless controller is installed on the push handle 11, and the wireless controller can be disassembled and assembled at will. The wireless controller can control the forward and reverse rotation of the motor 5, open the regulating valve 701 and adjust the amount of fuel delivered. According to the required weeding interval, the motor 5 is started to rotate its output end forward, driving the threaded block 201 on the threaded rod 2 to move forward in the axial direction of the threaded rod 2, and at the same time driving the rotating connecting rod group 6 rotatably connected on both sides of the threaded block 201 to move forward, thereby driving the rotating connecting rod group 6 connected to the inner wall of the limiting groove 401, and the angle between any two adjacent connecting rods is enlarged, and the long rod is extended in the axial direction of the fuel tank 9. The spacing between the points changes equidistantly, driving the rotationally connected limit slots 401 on the rotating connecting rod group 6 to extend, and the symmetrical end short rod drives the last limit adjustment plates 4 at both ends to extend, and at the same time, the limit adjustment plates 4 sliding in the fixed rail 3 and the extension rail 301, the limit adjustment plates 4 on the extension rail 301 drive the extension rail 301 to extend on both sides of the fixed rail 3, and at the same time, the spacing between adjacent limit adjustment plates 4 changes equidistantly, so that the spacing between the flame-spraying mechanisms 7 changes equidistantly, and when adjusted to a suitable position, the motor 5 is turned off by pressing the button on the push handle 11. When encountering a situation where weeds are arranged in different patterns, the wireless controller can be flexibly controlled to equidistantly adjust the spacing between the flame-spraying mechanisms 7 for weeding.

[0041] According to the type and density of weeding required, the wireless control machine on the push handle 11 is used to control the regulating valve 701 on the flame spraying mechanism 7 to open and adjust the amount of fuel to be delivered. The fuel in the fuel tank 9 is delivered to the flame spraying mechanism 7 through a pipeline connected to the feed port 801. When the regulating valve 701 is adjusted appropriately, the pulse igniter inside the flame spraying mechanism 7 is used to ignite. The push handle 11 is manually supported to drive the vehicle body 8 through the walking mechanism 10 to spray weeds. The fire hood 702 can spray and remove weeds.
