Description

Technical Field

[0001] The utility model relates to the technical field of saline-alkali land, in particular to a spraying and fertilizing device for planting in saline-alkali land. Background Technique

[0002] Saline-alkali land refers to the land where the soil contains a relatively high concentration of salts and alkaline substances, resulting in poor soil structure and low fertility, thus affecting the growth of plants. Saline-alkali land is a type of salt accumulation, which means that the salts contained in the soil affect the normal growth of crops. During the process of saline-alkali land treatment, fertilizing devices are often needed for fertilization treatment.

[0003] When the existing fertilizing devices are used to fertilize saline-alkali land, most of the fertilizers remain on the soil surface temporarily. Once it rains, it is very easy for the fertilizers to flow away with the rainwater. Moreover, the saline-alkali land itself lacks nutrients, which will lead to the loss of fertilizer nutrients and further affect the subsequent planting and growth of crops. Content of the Utility Model

[0004] The purpose of the utility model is to provide a spraying and fertilizing device for planting in saline-alkali land to solve the problems put forward in the above background technique.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 - 5 , an embodiment provided by the present invention: A spraying and fertilizing device for saline-alkali land planting, including a mounting frame 1. In the middle of the top of the mounting frame 1, a connecting frame 3 is fixedly installed by screws, which is convenient for connecting with the front of agricultural machinery such as farming machines, so as to facilitate rotary tillage during spraying and fertilizing to ensure sufficient fertilization. A plough blade 20 is installed in the middle of the front end of the mounting frame 1. A driving device 2 of the driving assembly is installed on the top of the mounting frame 1, which is mainly composed of a motor, a speed reducer, etc. (a relatively mature technology, not elaborated here), which can conveniently drive the rotating shaft 5 to rotate. Rotary tillage blades 4 are equidistantly arranged outside the rotating shaft 5, which can conveniently turn the soil to prevent fertilization from staying on the surface of the saline-alkali land.

[0023] Please refer to Figures 1 - 5, in order to ensure sufficient and uniform fertilization, avoid staying only on the surface, ensure the fertility of the fertilizer, prevent loss with rainwater, etc., and ensure the nutrients in the saline-alkali land during subsequent planting, two groups of medicine storage tanks 7 are symmetrically installed at the top of the installation frame 1. The inside is a mixed solution of fertilizer and water, which can be added through the medicine adding pipe 19 at the top after mixing. The side wall is provided with a mixing device 12 for facilitating auxiliary mixing (which can be composed of a motor, a rotating shaft, mixing blades, etc., a relatively mature technology, not elaborated here), which is convenient for mixing the fertilizer liquid inside. The two ends of the medicine storage tank 7 are connected with medicine outlet pipes 10 through a pump (not shown in the figure), which can facilitate the extraction. The bottom ends of the two front medicine outlet pipes 10 at the front end are jointly provided with a front spray pipe 8, and the bottom ends of the two rear medicine outlet pipes 10 at the rear end are jointly provided with a rear spray pipe 9. A plurality of groups of spray heads 11 are equidistantly arranged under the front spray pipe 8 and the rear spray pipe 9 (the number can be six or eight groups, etc., to ensure sufficient and uniform spraying). By providing two groups of spray pipes, the fertilizer can be sprayed first, then the soil can be turned over by the rotary tiller 4 to turn up the lower layer, and then sprayed again through the rear end, so as to spray and fertilize again, ensure sufficient and thorough fertilization, and avoid the fertilizer staying only on the surface layer, which affects the fertility of the saline-alkali land during subsequent planting.

[0024] Please refer to Figures 1 - 5 , in order to level the soil after spraying and fertilizing and cover the sprayed fertilizer, a rotating rod 13 of a rotating component is installed at the rear end of the installation frame 1. A scraping plate 6 is rotatably arranged outside the rotating rod 13. In order to facilitate the adjustment of the inclination angle of the scraping plate 6 to better contact the ground, two groups of rotating blocks 15 of a positioning mechanism are welded at equal intervals at the rear end of the bottom of the scraping plate 6. An adjusting rod 14 is rotatably arranged on the rotating block 15, and positioning holes 18 of an inserting component are equidistantly opened on it. A clamping plate 16 is welded at the rear end of the installation frame 1, and a through hole for facilitating the insertion of the positioning rod 17 is opened on the side surface of the clamping plate 16.

[0025] Working principle: When the utility model is in use, the whole device is connected and fixed to the vehicle head through the connecting frame 3. Then, the mixed fertilizer liquid is added into the medicine storage tank 7 through the medicine adding pipe 19. By pulling out the positioning rod 17, the adjusting rod 14 can be pushed and pulled up and down. Cooperating with the rotating block 15 and the rotating rod 13, the scraper 6 can be rotationally adjusted to make it fit the ground, which is convenient for subsequent leveling operation. Then, the positioning rod 17 is inserted into the positioning hole 18 to fix the adjusting rod 14, and further fix the scraper 6. At this time, by driving the vehicle head to move, the whole device moves. By the operation of the driving device 2, the rotary tillage blades 4 on the rotating shaft 5 can work to rotary till and turn over the soil. At the same time, the fertilizer liquid in the medicine storage tank 7 is pumped out through the medicine outlet pipe 10 and sprayed out through the nozzles 11 under the front spray pipe 8 and the rear spray pipe 9 to spray the fertilizer liquid. After spraying the fertilizer, the soil is turned over by the rotary tillage blades 4 to turn up the lower layer, and then sprayed again through the rear end to perform secondary spraying and fertilization, ensuring the thoroughness of fertilization, avoiding the fertilizer staying only on the surface layer and affecting the fertility of subsequent planting in saline-alkali land. Then, it is leveled by the scraper 6.
