[0002] Rice weeding is a very important management task in the rice planting process. The purpose is to remove weeds that compete with rice for light, water and fertilizer, ensure the healthy growth of rice and increase yield. The weeding methods are mainly divided into mechanical weeding, chemical weeding and biological weeding. Among them, mechanical weeding mainly includes tillage and intertillage. Before rice planting, tillage is used to destroy the growth environment of weeds and reduce the stock of weed seeds. During the growth of rice, intertillage can cut off the roots of weeds and kill them.
[0003] The common weeding devices used in existing rice planting include cultivators and rakes. Cultivators are large and medium-sized agricultural machinery equipment. In most mountainous and hilly areas of my country, they are easily restricted by roads and farmland terrain and cannot play their role and benefits. When using them, farmers often need to bend down and swing the rake again and again to dig out the weeds in the rice fields, which consumes a lot of physical strength and increases the labor intensity of farmers. Utility Model Content

[0019] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
[0020] Example 1
[0021] The weeding device for rice planting described in this embodiment is as follows: Figure 1 , Figure 3 and Figure 4As shown, it includes a horizontally arranged sliding plate 5, one end of the sliding plate 5 away from the handle 2 is in an arc-shaped upward shape, and the sliding plate 5 is made of iron, steel, aluminum, plastic and other materials. When the sliding plate 5 is placed horizontally in the rice field, the sliding plate 5 can be located on the surface of the mud. The principle is: the surface area of the sliding plate 5 is large, which enables it to disperse the pressure on the ground. When the plate is placed on the mud in the rice field, its weight will be evenly distributed on a larger contact surface, thereby reducing the pressure per unit area, so that the sliding plate 5 is not easy to sink into the mud; and after one end of the sliding plate 5 is in an arc-shaped upward shape, the sliding plate 5 can optimize the interaction between the sliding plate 5 and the water during the movement process, reduce the impact of water on the sliding plate 5, thereby reducing the water resistance, and make the sliding plate 5 move faster and more stably. The principle is the same as the principle of the bow of a ship tilted upward; so that farmers can operate more easily and labor-saving;
[0022] The bottom of the sliding plate 5 is fixed with a plurality of guide bars 6 which are evenly spaced and aligned along its length direction. The bottoms of all the guide bars 6 are blade-shaped. In this embodiment, two guide bars 6 are used. The two guide bars 6 are fixed to the bottom of the sliding plate 5 in an aligned manner along its length direction. When the sliding plate 5 moves, the guide bars 6 can guide the direction of movement of the sliding plate 5, so that the sliding plate 5 can move in a straight line and is not prone to the situation of movement angle deviation. Its principle is the same as the working principle of the rudder. When the bottom of the guide bar 6 contacts the stone, it can reduce the friction and cut the mud at the bottom and the front to avoid the movement of the sliding plate 5 being blocked, so that farmers can move more easily and labor-saving.
[0023] The sliding plate 5 is provided with an "L"-shaped mounting plate 8, a vertical section of the mounting plate 8 is fixed to the top of the sliding plate 5, and the mounting plate 8 is an inverted "L"-shaped structure, with a vertical end of the mounting plate 8 fixed to the top of the mounting plate 8 and a horizontal end facing the front of the sliding plate 5;
[0024] A push tube 1 is fixed in an inclined shape on a horizontal section of the mounting plate 8, one end of the push tube 1 is fixed at the center of the top of the horizontal section of the mounting plate 8, and the unfixed end of the push tube 1 faces the direction of the farmer, so that the farmer can push the sliding plate 5 more easily and labor-savingly. When in use, the farmer pushes the sliding plate 5 to slide between the rice fields through the push tube 1; the push tube 1 is a circular tube, and of course a square or other shaped tube can also be used. The push tube 1 is made of metal materials such as iron, steel, and alloy;
[0025] A handle 2 is fixed to the unfixed end of the push tube 1, and the handle 2 can facilitate the farmer to control the push tube 1, so that the farmer can operate more conveniently;
[0026] The handle 2 is covered with a protective cover, and the protective cover is provided with anti-skid patterns for increasing friction. The protective cover is made of rubber, PVC, silicone, synthetic fiber, foam and other materials, which are relatively soft and can make farmers feel more comfortable when holding the handle 2. The anti-skid patterns can increase the friction between the hand skin and the protective cover, thereby preventing the hand and the handle 2 from slipping during use.
[0027] An inner rod 3 is independently installed in the push tube 1, and there is a gap between the inner rod 3 and the push tube 1, so that the inner rod 3 can move in the push tube 1;
[0028] The push tube 1 is passed through the end of the inner rod 3 facing the sliding plate 5, and a weeding fork 7 for cleaning weeds is fixed thereon; a through hole for the inner rod 3 to pass through independently is opened on the top of a horizontal section of the mounting plate 8, and the end of the inner rod 3 facing the sliding plate 5 can pass through the push tube 1 and the through hole; the weeding fork 7 is an agricultural fork commonly used in rural areas for weeding, turning the soil, and forking fertilizers. The weeding fork 7 is aligned with the axis of the inner rod 3, so that the weeding fork 7 is inclined, and the tip of the fork faces the front and lower direction of the moving direction of the sliding plate 5;
[0029] The sliding plate 5 is provided with a plurality of through holes 4 which are connected up and down and through which the fork rods of the weeding fork 7 pass independently. The number of the through holes 4 is the same as the number of the fork rods on the weeding fork 7. When the inner rod 3 moves in the push tube 1, it drives the weeding fork 7 to move, so that the fork rod on the weeding fork 7 passes through the through holes aligned therewith and is inserted into the mud at the bottom of the sliding plate 5, so that the fork rod of the weeding fork 7 forms an angle with the bottom of the sliding plate 5; when in use, the sliding plate 5 moves forward on the surface of the mud, and the weeding fork 7 is inserted into the mud and moves forward. During the movement of the weeding fork 7, the roots of the weeds will block its fork rod, and the fork rod can take advantage of the situation to remove the weeds. The roots are pulled out, and the pulled out weeds are stored along the angle between the fork rod and the bottom of the sliding plate 5. When there are a lot of weeds stored, the inner rod 3 is pulled, and the inner rod 3 drives the weeding fork 7 to move, so that the fork rod on the weeding fork 7 is pulled out of the mud and passes through the through hole 4. When the fork rod on the weeding fork 7 passes through the through hole 4, the hole wall of the through hole 4 can scrape off the weeds entangled on the fork rod, thereby avoiding affecting the subsequent use effect. Then, the sliding plate 5 is continuously pushed forward to make the pulled out weeds pass through the bottom of the sliding plate 5. The farmer can throw the pulled out weeds out of the rice field and wait for subsequent processing, so that the farmer can weed more easily and labor-savingly, and reduce the labor intensity of the farmer;
[0030] To further explain, Figure 2 , Figure 3 and Figure 4As shown, the present embodiment preferably includes a pull rod 9, which is fixed on one end of the inner rod 3 located in the push tube 1, and a slide groove is provided on the push tube 1 for one end of the pull rod 9 to independently pass through, and a screw is installed on the push tube 1 for locking the inner rod 3 after the movement; the pull rod 9 is fixed to the end of the unfixed end of the inner rod 3, and the slide groove is provided on the end of the push tube 1 facing the farmer, when the pull rod 9 is pulled, the pull rod 9 will move along the slide groove, and the pull rod 9 drives the weeding fork 7 to move through the inner rod 3, thereby adjusting the depth of the fork rod on the weeding fork 7 inserted into the mud, so as to adapt to the depth of the mud in different rice fields; A threaded hole communicating with the inside and outside is provided on the push tube 1, and the threaded end of the screw passes through the threaded hole and presses on the inner rod 3 to lock the moved inner rod 3, thereby locking the moved weeding fork 7; this scheme as a whole constitutes an adjustment component for adjusting the length of the fork rod passing through the through hole; of course, the adjustment component can also adopt a pull rope, one end of the pull rope is fixed on the weeding fork 7, and a screw for locking the inner rod 3 is installed on the push tube 1. The farmer controls the weeding fork 7 to move in the direction of the inner rod 3 by the pull rope, and then locks the moved inner rod 3 by the screw, thereby locking the weeding fork 7.
[0031] In actual use, firstly, the sliding plate 5 is placed horizontally in the rice field, and the pull rod 9 is pushed by hand, so that the pull rod 9 drives the weeding fork 7 to move in the direction of the mud through the inner rod 3, and the fork rod on the weeding fork 7 passes through the through hole aligned with it and is inserted into the mud at the bottom of the sliding plate 5. When the insertion depth is appropriate, the screw is turned to lock the moved inner rod 3, thereby locking the weeding fork 7. After that, the farmer can hold the handle 2 and push the sliding plate 5 forward on the surface of the mud through the push tube 1, and the weeding fork 7 is inserted into the mud and moves forward. During the movement of the weeding fork 7, the roots of the weeds will block its fork rod, and the fork rod can take advantage of the situation to push the weeds The roots of the grass are pulled out, and the pulled out weeds are stored along the angle between the fork rod and the bottom of the sliding plate 5. When there are more weeds stored, the inner rod 3 is pulled, and the inner rod 3 drives the weeding fork 7 to move, so that the fork rod on the weeding fork 7 is pulled out of the mud and passes through the through hole 4. When the fork rod on the weeding fork 7 passes through the through hole 4, the hole wall of the through hole 4 can scrape off the weeds entangled on the fork rod, thereby avoiding affecting the subsequent use effect. Then, the sliding plate 5 is continued to be pushed forward to make the pulled out weeds pass through the bottom of the sliding plate 5. The farmer can throw the pulled out weeds out of the rice field and wait for subsequent processing, so that the farmer can weed more easily and labor-savingly, reducing the labor intensity of the farmer.
