Description

Technical Field

[0001] The present application belongs to the technical field of agricultural machinery, and specifically relates to an electric rice field weeder. Background Art

[0002] As crops in the fields grow, weeds also grow along with them. Weeds compete with crops for soil moisture and nutrients, occupy farmland space, and affect the growth of crops. This not only reduces the yield and quality of crops, but also indirectly contributes to the breeding and spread of pests and diseases. Therefore, weeds need to be removed.

[0003] Most of the existing technologies use two methods to remove weeds, one is chemical weeding and the other is mechanical weeding. Chemical weeding is the fastest, but if the herbicide is used improperly, it will not only waste the herbicide, but also cause excessive pesticide residues in agricultural products, leading to pesticide pollution of soil, water environment, and even poisoning of personnel. The mechanical weeding effect in the existing technology is low, and it can only simply cut the weeds on the ground, and it is difficult to completely remove the weeds. Although some weeders can turn the grass roots out to the ground, the weeds will continue to grow in rainy weather, so the weeds will continue to grow after a period of weeding.

[0014] Figure 1 It is a structural schematic diagram of the electric rice field weeder of the present application.

[0015] Figure 2 An exemplary structure of the hook tooth member on the rotating disk in the electric rice field weeder of the present application is shown. DETAILED DESCRIPTION

[0016] In order to better help understand the technical solution of the present application, the specific implementation methods of the present application will be described in detail below with reference to the accompanying drawings.

[0017] Figure 1 The schematic diagram of the structure of the electric rice field weeder of the present application is shown. Figure 1 As shown, the electric rice field weeder mainly includes a handle 1, a push rod 2, a rechargeable motor 3, a rotating disk 7 and a floating plate component 6.

[0018] The handle 1 is generally U-shaped, including two gripping parts and a gripping part connecting rod connecting the two gripping parts. One end of the push rod 2 is fixedly connected to the gripping part connecting rod of the handle 1, and the other end of the push rod 2 is connected to the rotating shaft 10 of the rotating disk 7 through a bearing 11. The push rod 2 is preferably a telescopic rod member.

[0019] The rechargeable motor 3 is connected to the rotating shaft 10 through the transmission member 4 and drives the rotating shaft 10 to rotate. The rotating shaft 10 passes through the center of the rotating disk 7 and is connected to the rotating disk 7, and there is no relative movement between the rotating disk 7 and the rotating shaft 10. That is, when the rotating shaft 10 rotates under the drive of the rechargeable motor 3, the rotating disk 7 rotates together.

[0020] The rechargeable motor 3 includes a motor and a rechargeable battery for supplying power to the motor. For the sake of compactness and stability, the motor and the rechargeable battery are packaged together in a motor housing and arranged above the rotating disk 7. A charging interface is reserved on the motor housing. The rechargeable battery and the motor can be any suitable rechargeable battery and motor known in the prior art, respectively.

[0021] In order to facilitate the operation of the electric rice field weeder, a control switch 9 which is electrically connected to the rechargeable motor 3 and controls the operation of the rechargeable motor 3 is provided on the handle 1 .

[0022] The floating plate member 6 is located at the front side of the rotating disk 7 in the forward direction, and is used to balance the orientation of the electric paddy field weeder and prevent the electric paddy field weeder from sinking, and is configured to be fixedly connected to one end of the rigid bow-shaped connecting member 5. The other end of the bow-shaped connecting rod 5 is connected to both ends of the rotating shaft 10 through a bearing member 11.

[0023] The floating plate member 6 is generally in the shape of a shuttle, and the surface thereof in contact with the water surface of the paddy field is in an arc shape, and the other surface is a plane, and the interior is hollow. The length direction of the floating plate member 6 is consistent with the forward direction of the electric paddy field weeder. The floating plate member 6 of this configuration has less resistance when the electric paddy field weeder is moving. The floating plate member 6 can be made of any suitable material known in the art, preferably a floating plate member made of plastic.

[0024] The surface of the rotating disk 7 is provided with a plurality of groups of holes 8 radiating outward from the center of the rotating disk 7. In each group, the holes 8 are spaced 10 mm apart in sequence. At least a portion of the edge of each hole 8 extends outward to protrude from the surface of the rotating disk 7 to form a hook tooth member 12. The diameter of the rotating disk 7 is preferably 20-50 cm. The extension length of the hook tooth member 12 is preferably 5-10 cm, and each hook tooth member 12 preferably forms an angle of 45° to 90° with the surface of the rotating disk 7.

[0025] The hole 8 is preferably an isosceles triangular hole with a waist length of 10 mm and a base of 6 mm, and the hook teeth member 12 extends outward from the corresponding edge of the triangular hole to protrude from the plane of the hole, such as Figure 2As shown. Each hook tooth member 12 includes a first extension portion 121 and a second extension portion 122. The first extension portion 121 extends from the edge of the triangular hole to be continuous with the second extension portion 122. The second extension portion 122 extends obliquely from the end of the first extension portion 121 in a direction away from the triangular edge. The second extension portion 122 is inclined 90°-135° relative to the first extension portion 121, and the length of the second extension portion 122 is less than the length of the first extension portion 121, preferably 1 / 3 to 1 / 2 of the length of the first extension portion 121.

[0026] Preferably, a plurality of additional hook-tooth members (not shown) are further provided along the peripheral edge of the rotating disk 7, each of which extends outward from the peripheral edge of the rotating disk 7 and forms an angle of 45° to 90° with the surface of the rotating disk 7. Each of the additional hook-tooth members preferably has a first extension portion and a second extension portion of the same or similar structure as the hook-tooth member 12.

[0027] When the electric rice field weeder is working, the operator first holds the two grips on the handle 1 to stabilize the orientation of the electric rice field weeder and control its direction of travel, and turns on the control switch 9 to start the rechargeable motor 3. The rechargeable motor 3 drives the rotating shaft 10 to rotate through the transmission member 4, and the rotating disk 7 rotates together. The rotating disk 7 is parallel to the surface of the rice field, and the hook tooth member 12 and the additional hook tooth member extend into the soil. When rotating, the hook tooth member 12 and the additional hook tooth member stir the soil in the ridges and ditches of the rice field. At this time, the weeds in the ridges and ditches of the rice field are stirred and rotated into the soil. The weeds that are stirred and buried in the soil cannot gradually rot in the mud due to photosynthesis. During the weeding process, the electric rice field weeder is pushed forward by the operator's hand push force and the reaction force of the hook tooth member 12 and the additional hook tooth member.

However, those skilled in the art should understand that the above implementation methods are only preferred implementation methods of the present invention, and the detailed description is only to help readers better understand the spirit of the present invention, and it is not a limitation on the scope of protection of the present invention. On the contrary, any improvements or modifications based on the spirit of the present invention should fall within the scope of protection of the present invention.
