Description

Technical Field

[0001] The utility model relates to the technical field of tobacco planting, in particular to a device for improving tobacco-growing soil by using biochar. Background Art

[0002] In order to improve the carbon-nitrogen ratio in tobacco-growing soil, especially to increase the proportion of active organic carbon, it is necessary to supplement biochar fertilizer to the soil. Therefore, fertilization is an indispensable step in flue-cured tobacco planting in tobacco-growing agriculture. The existing fertilization operation usually uses a ring-type fertilizer applicator to apply fertilizer on the soil around the crop seedlings, which is beneficial for the crops to absorb. The traditional ring-type fertilizer applicator is a manual fertilization tool. When in use, a person has to carry a fertilizer tank on the back. The fertilizer tank is connected with a fertilization device through a discharge hose, and the person holds the fertilization device to apply fertilizer. The labor intensity is very high, and only one tobacco plant can be fertilized at a time, and the efficiency is very low. Usually, the plants need to be covered with plastic film in the seedling stage. Therefore, when fertilizing, it is also necessary for the person to manually tear open the fertilization opening, which is inconvenient to use. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a fertilization device that can fertilize multiple plants at one time, reduces the labor intensity of personnel, improves the fertilization efficiency, and is convenient for personnel to use.

[0004] The utility model is realized by the following technical solutions. A device for improving tobacco-growing soil by using biochar includes a moving frame and fertilizer applicators located on the left and right sides of the moving frame. A support plate is slidably installed on the moving frame, and a first telescopic cylinder for driving the support plate to slide up and down is arranged on the moving frame. The fertilizer applicator is slidably installed on the support plate, and a second telescopic cylinder for driving the fertilizer applicator to slide left and right is arranged on the moving frame. The fertilizer applicator includes a fertilizer tank, a chute pipe and an annular hopper connected in sequence from top to bottom. The top and bottom of the fertilizer tank are respectively provided with a feed inlet and a discharge outlet, and a discharge valve is installed on the discharge outlet. The annular hopper includes an outer hopper and an inner hopper arranged coaxially, and an annular feeding cavity is formed between the outer hopper and the inner hopper.

[0005] In this solution, the moving frame drives the fertilizer applicator to perform fertilization operations, reducing the labor amount of personnel. Fertilizer applicators are arranged on both the left and right sides of the moving frame, and the left and right rows of tobacco-growing soil can be fertilized at one time, improving the fertilization efficiency. The fertilizer applicator is filled with fertilizer through the fertilizer tank, and the fertilizer enters the annular hopper through the chute pipe, so as to apply the fertilizer in a ring shape on the soil surface around the crop seedlings, improving the tobacco-growing soil. The fertilizer applicator is driven by a second oil cylinder to slide left and right on the support plate, so as to facilitate adjusting the alignment of the left and right directions to the fertilization position. The first oil cylinder on the moving frame drives the support plate to slide up and down, so that the annular hopper of the fertilizer applicator is inserted downward into the plastic film to contact the soil for fertilization.

[0006] As an optimization, the moving frame includes a top plate and a moving bottom plate that face each other vertically. The top plate and the moving bottom plate are fixedly connected by vertical support columns. The support plate is slidably connected to the support columns and slides up and down along the support columns. One end of the first telescopic cylinder is connected to the top plate, and the other end of the first telescopic cylinder is connected to the support plate. In this optimized solution, the support plate slides on the support columns to achieve a sliding connection with the moving frame.

[0007] As an optimization, the chute is slidably connected to the support plate. A long strip-shaped sliding hole for the chute to slide left and right is provided on the support plate. One end of the second telescopic cylinder is connected to the moving frame, and the other end of the second telescopic cylinder is connected to the chute. In this optimized solution, the chute slides left and right along the long strip-shaped sliding hole to achieve a sliding connection with the support plate.

[0008] As an optimization, the bottom end of the outer hopper has a serrated structure. This optimized solution facilitates the insertion of the bottom end of the outer hopper into the plastic film and contact with the soil, making it more convenient to use.

[0009] As an optimization, two fertilizer applicators are provided on each of the left and right sides of the moving frame. The four fertilizer applicators are arranged in pairs on the left and right sides of the moving frame. In this optimized solution, two plant seedlings on the same side are fertilized at one time, further improving the fertilization efficiency.

[0010] As an optimization, a material distribution plate is fixedly connected to the top of the moving frame. A plurality of material distribution pipes are provided at the bottom of the material distribution plate. The material distribution pipes correspond to the fertilizer applicators one by one. The end of the material distribution pipe away from the material distribution plate extends above the feed inlet of the fertilizer tank. In this optimized solution, fertilizer is added to the material distribution plate, and the fertilizer is respectively distributed and conveyed to each fertilizer tank through a plurality of material distribution pipes, eliminating the need to add fertilizer to each fertilizer tank one by one and improving the convenience of use.

[0011] As an optimization, a plurality of flow guiding plates are fixedly provided in the inner hole of the chute. The plurality of flow guiding plates are evenly distributed in a circle and extend along the length direction of the chute. The plurality of flow guiding plates divide the inner cavity of the chute evenly. In this optimized solution, the inner cavity of the chute is evenly divided by a plurality of flow guiding plates, making the fertilizer more evenly distributed circumferentially when passing through the chute.

[0012] The beneficial effects of the present utility model are as follows: The fertilizer applicator is driven by the moving frame to perform fertilization operations, reducing the labor intensity of personnel. Two fertilizer applicators are provided on each of the left and right sides of the moving frame, and the left and right rows of tobacco-growing soil can be fertilized at one time, improving the fertilization efficiency. The fertilizer applicator is filled with fertilizer through a fertilizer tank, and the fertilizer enters the annular conical hopper through a chute, so that the fertilizer is applied in a ring on the soil surface around the crop seedlings, improving the tobacco-growing soil. The fertilizer applicator is driven by a second oil cylinder to slide left and right on the support plate, so as to facilitate the adjustment of the alignment in the left and right directions to the fertilization position. The first oil cylinder on the moving frame drives the support plate to slide up and down, so that the fertilizer applicator at the aligned position contacts the soil downward for fertilization.
