Description

Technical Field

[0001] The present invention relates to the technical field of garden weeding, and in particular to a garden weeding machine with a pesticide weeding function. Background Art

[0002] In order to maintain the beauty of the garden, it is necessary to remove the weeds in the garden. The most primitive weeding method is for workers to cut the grass with a sickle. This weeding method is slow and the labor intensity of workers is high. In order to improve the weeding efficiency, people have invented a weeding machine to replace manual weeding. At present, there are a variety of existing weeding machines, but mainly through the motor to drive the cutter head to rotate to achieve the cutting of weeds. However, whether it is the weeding machine or manual weeding, it is impossible to pull out the weeds by the roots. The survival ability of weeds is very strong. Without removing the roots, they will grow by themselves and eventually weeds will grow again.

[0003] In order to improve the weeding effect, people have improved the weeding machine and added a pesticide spraying function to the weeding machine, combining the two weeding methods of physical weeding and chemical weeding. The weeding effect of this kind of weeding machine is better than that of the traditional weeding machine, but it also pollutes the environment. Because the existing weeding machine sprays pesticides on the weeds through a spray head, only a small part of the sprayed pesticide mist can fall on the weeds, and most of the rest of the pesticide mist falls into the soil. The utilization rate of pesticides is extremely low, which not only wastes pesticides but also pollutes the environment, resulting in pesticide residues on the planted crops.

[0004] Therefore, it is necessary to propose a weeding machine that can improve the utilization rate of pesticides to reduce environmental pollution and reduce pesticide residues on crops. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem of low utilization rate of pesticides of traditional weeding machines, and now a garden weeding machine with a pesticide weeding function is provided.

[0006] The technical solution of the present invention is as follows: A garden weeding machine with a pesticide weeding function includes a frame and traveling wheels. A power device, a cutter head and a medicine barrel are provided on the frame. The power device drives the cutter head to rotate. A cutter is installed on the cutter head. The frame is fixedly connected with a pesticide applying device. The pesticide applying device is in contact with the surface of the cutter. A connecting pipe is provided between the medicine barrel and the pesticide applying device. The connecting pipe communicates the medicine barrel with the pesticide applying device.

[0007] Further, the pesticide applying device includes a first fixing member. The first fixing member is provided with a groove. A coating member is fixedly connected in the groove. The first fixing member is fixedly connected with the frame. The groove communicates with the connecting pipe. The coating member is in contact with the surface of the cutter.

[0008] Further, the frame is fixedly connected with a second fixing member, and the second fixing member is fixedly connected with a scrubbing member, and the scrubbing member contacts the surface of the tool.

[0009] Further, a drying device is provided between the scrubbing device and the pesticide application device. The drying device is fixedly connected with the frame, and the drying device dries the surface of the tool.

[0010] Further, when the power device drives the cutter head to rotate, the tool sequentially passes through the scrubbing member, the drying device and the application member.

[0011] Further, the application member contacts the lower surface of the tool.

[0012] Further, the scrubbing member contacts the upper surface and the lower surface of the tool respectively.

[0013] Further, a cutting groove is provided on the frame, and the cutter head and the tool are both located in the harvesting groove.

[0014] Further, a diesel generator is fixedly connected to the frame, and the diesel generator supplies power to the power device.

[0015] Further, the connecting pipe is communicated with a pressure pump, and the pressure pump is fixedly connected with the frame.

[0016] For the garden weeding machine with the pesticide weeding function of the present invention, the medicine barrel is filled with pesticide. The pesticide is sent to the pesticide application device through the connecting pipe. By contacting the tool through the pesticide application device, the pesticide can be applied on the surface of the tool. When the power device drives the cutter head to rotate, the tool rotates to cut the weeds. Since the surface of the tool is coated with pesticide, the pesticide can be transferred from the surface of the tool to the cross-section of the weeds, and the pesticide enters the interior of the weeds through the cutting cross-section of the weeds, so as to completely remove the weeds. Since only the pesticide is applied on the tool and the pesticide will only be transferred from the tool to the weeds when the tool contacts the weeds, the pesticide is saved. Compared with the traditional technology, this technical solution abandons the traditional spraying method and uses the transfer of pesticide when the tool cuts the weeds. The pesticide that does not contact the weeds will continue to stay on the surface of the tool, while the pesticide that contacts the weeds exerts the weeding effect, improving the pesticide utilization rate, thereby reducing environmental pollution and reducing the pesticide residue on the crops.

Detailed implementation manners

[0019] In order to make the technical means, technical features, invention purposes and technical effects achieved by the present invention easy to understand, the present invention will be further described below with reference to specific illustrations.

[0020] Embodiment 1: As Figure 1 and Figure 2 shown, this embodiment provides a garden weeding machine with a pesticide weeding function, including a frame 1 and traveling wheels 2. A power device 3, a cutter head 4 and a medicine cylinder 5 are provided on the frame 1. The power device 3 drives the cutter head 4 to rotate. A cutter 6 is installed on the cutter head 4. The frame 1 is screwed with a pesticide application device 7. The pesticide application device 7 is in contact with the surface of the cutter 6. A connecting pipe 8 is provided between the medicine cylinder 5 and the pesticide application device 7. The connecting pipe 8 communicates the medicine cylinder 5 with the pesticide application device 7. Preferably, the power device 3 is screwed to the frame 1. The traveling wheels 2 rotate relative to the frame 1. The cutter head 4 is connected to the frame 1 through a pin shaft. The power device 3 drives the cutter head 4 to rotate through the pin shaft. Preferably, the power device 3 is a motor. Preferably, the cutter 6 is screwed to the cutter head 4. The medicine cylinder 5 is filled with pesticide. The pesticide is sent into the pesticide application device 7 through the connecting pipe 8. By contacting the pesticide application device 7 with the cutter 6, the pesticide can be applied to the surface of the cutter 6. When the power device 3 drives the cutter head 4 to rotate, the cutter 6 rotates to cut weeds. Since the surface of the cutter 6 is coated with pesticide, the pesticide can be transferred from the surface of the cutter 6 to the cross-section of the weeds. The pesticide enters the interior of the weeds through the cutting cross-section of the weeds, thereby completely removing the weeds. Since only the pesticide is applied to the cutter 6 and the pesticide will only be transferred from the cutter 6 to the weeds when the cutter 6 contacts the weeds, the pesticide is saved. This technical solution abandons the traditional spraying method and uses the transfer of pesticide when the cutter 6 cuts weeds. The pesticide that does not contact the weeds will continue to stay on the surface of the cutter 6, while the pesticide that contacts the weeds exerts a weeding effect, improving the pesticide utilization rate, thereby reducing environmental pollution and reducing the pesticide residue on crops.

[0021] Preferably, the pesticide application device 7 includes a first fixing member 9 provided with a groove 10, in which an application member 11 is connected by clamping or bonding. The first fixing member 9 is screwed to the frame 1. The groove 10 communicates with the connecting pipe 8. The application member 11 contacts the surface of the tool 6. The connecting pipe 8 sends the pesticide to the application member 11 through the groove 10, and the application member 11 contacts the surface of the tool 6, so as to apply the pesticide to the surface of the tool 6. Preferably, the application member 11 is a sponge pad.

[0022] Preferably, the frame 1 is screwed with a second fixing member 12, and a scrubbing member 13 is connected to the second fixing member 12 by clamping or bonding. The scrubbing member 13 contacts the surface of the tool 6. After the tool 6 cuts weeds, the surface will be stained with plant tissue fluid or juice. If it contacts the pesticide on the application member 11 at this time, the concentration of the pesticide will be reduced, thus affecting the efficacy of the pesticide and being unfavorable for weed control. When the tool 6 rotates, the scrubbing member 13 will scrub the plant tissue fluid or juice on the surface of the tool 6 clean. Preferably, the scrubbing member 13 is a sponge pad.

[0023] Preferably, a drying device 14 is provided between the scrubbing device and the pesticide application device 7. The drying device 14 is screwed to the frame 1. The drying device 14 dries the surface of the tool 6. Since the tool 6 becomes wet after being stained with plant tissue fluid or juice, even if there is a scrubbing member 13 to scrub the tool 6, it is very difficult to dry the surface of the tool 6 completely under the condition of high-speed rotation. The drying device 14 can dry the surface of the tool 6, accelerating the evaporation of the moisture on the surface of the tool 6, so as not to affect the concentration of the pesticide applied on the surface of the tool 6. Preferably, the drying device 14 is a blower, which includes a fan and a motor.

[0024] Preferably, when the power device 3 drives the cutter head 4 to rotate, the tool 6 passes through the scrubbing member 13, the drying device 14 and the application member 11 in sequence.

[0025] Preferably, the application member 11 contacts the lower surface of the tool 6.

[0026] Preferably, the scrubbing member 13 contacts the upper surface and the lower surface of the tool 6 respectively.

[0027] Preferably, a cutting groove 15 is provided on the frame 1, and the cutter head 4 and the tool 6 are both located in the harvesting groove.

[0028] Preferably, a diesel generator 16 is screwed to the frame 1, and the diesel generator 16 provides power for the power device 3.

[0029] Preferably, the connecting pipe 8 communicates with a pressure pump 17, and the pressure pump 17 is screwed to the frame 1. Preferably, the diesel generator 16 also provides power for the pressure pump 17.

[0030] During use, people control the rotation of the walking wheels 2 so that the frame 1 moves in the weeds. The diesel generator 16 provides power for the power device 3, and the power device 3 drives the cutter head 4 to rotate. The cutter 6 cuts the weeds. During the rotation of the cutter 6, it will successively pass through the scrubbing device, the drying device 14 and the pesticide coating device 7, so as to coat the surface of the cutter 6 with pesticides. When the cutter 6 cuts the weeds, it will apply the pesticides to the cut ends of the weeds, thereby killing the weeds.

[0031] In summary, the above are only the preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made to the content of the scope of the patent application of the present invention shall fall within the technical scope of the present invention.
