Description

Technical Field

[0001] The utility model relates to the technical field of weeding devices, in particular to a weed removal device used for rice seedling cultivation. Background Art

[0002] Rice is a very important food. When planting rice, the seedlings need to be transplanted into paddy fields for cultivation to ensure that there is enough space for the subsequent seedlings to grow. There will be a certain distance between the seedlings, and they will be distributed at equal distances. During the growth of the seedlings, weeds will also grow rapidly, so impurities need to be removed to ensure that the seedlings have enough space to grow and enough sunlight.

[0003] However, the following problems still exist during the use of the current weed removal device:

[0004] The existing weed removal device uses an electrically driven hull to move in the paddy field, so as to remove impurities through a hook set at the rear end of the hull. However, the hook of the existing weed removal device is directly fixed on the hull, so it is difficult to adjust the distance between the hooks, and it is impossible to ensure that the weeds at different intervals are fully removed. Utility Model Content

[0007] Furthermore, the adjustment component includes a fixing plate and a connecting plate. The left side of the weeding hull is interconnected with the fixing plate, and the fixing plate is interconnected with the connecting plate. Through the above structure, it is convenient to install and fix the connecting plate through the fixing plate.

[0008] Furthermore, a guide assembly is installed on the adjustment assembly, and the adjustment assembly also includes a first fixing screw and an extension plate, and the first fixing screw is connected to the connecting plate through a first threaded hole opened on the connecting plate, and the extension plate is penetrated by the first fixing screw. Through the above structure, it is convenient to install and fix the connecting plate and the extension plate through the first fixing screw.

[0009] Furthermore, the extension plate is slidably connected to the connecting plate through a square groove opened at its upper end, and second threaded holes are opened on the extension plate at equal distances, and the second fixing screw is connected to the extension plate. Through the above structure, it is convenient to limit the movement range of the extension plate through the connecting plate.

[0010] Furthermore, the guide assembly includes a reinforcement plate and a connecting guide rod, and the reinforcement plate is fixedly installed on the left side of the extension plate, and the reinforcement plate is fixedly connected to the connecting guide rod. Through the above structure, it is convenient to support the support plate under the action of the connecting guide rod without affecting the movement of the support plate.

[0011] Furthermore, the connecting guide rod is slidably connected to the support plate via a through sliding groove provided on the support plate, and the outer surface of the connecting guide rod is set to be smooth. Through the above structure, the friction between the support plate and the connecting guide rod is easily reduced.

[0012] Furthermore, a sharp inclined hook is provided at the lower end of the weeding chain, and the weeding chain is made of stainless steel. Through the above structure, the weeds in the paddy field can be removed easily under the action of the weeding chain.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The weed removal device for rice seedling cultivation can adjust the installation position of the fastening plate through the second fixing screw, thereby adjusting the distance between the weeding chains, so that seedlings with different spacings can be weeded, which can effectively ensure the use range of the device, and by adjusting the height of the extension plate, paddy fields with different depths can be weeded, thereby increasing the use effect of the device, ensuring that the weeds are fully removed, and avoiding the situation where the weed roots are not completely cleaned.
