Description

Technical Field

[0001] The invention relates to the technical field of soil remediation, and in particular to a device for removing seeds of Stellera chamaejasme in grassland from soil. Background Art

[0002] The device for removing seeds of Stellera chamaejasme from the soil is a special equipment developed to meet the needs of grassland ecological protection. Stellera chamaejasme is a perennial herb whose seeds have a strong ability to spread in the soil, causing damage to the grassland ecology. Traditional removal methods are inefficient and difficult to completely solve the problem. Therefore, it is particularly important to develop an efficient and reliable removal device. The device is based on the principle of combining chemical treatment with physical soil turning. It aims to kill stellera chamaejasme seeds by spraying specific agents, and using mechanical devices to turn the soil to promote the penetration of agents, so as to achieve the purpose of effectively removing stellera chamaejasme seeds. The development and application of this device are of great significance to maintaining the ecological balance of grasslands and protecting grassland resources.

[0003] After searching, the invention patent of Chinese patent number CN118216288B discloses a grassland Stellera chamaejasme with roots mowing device, including a handle, a controller, a sliding structure, a gasoline engine, a junction box, a digging structure, a cutting structure, a supporting structure, a mobile structure, a rotating connector and a transmission shaft. The gasoline engine drives the digging structure to rotate, so that the digging structure spirals into the soil, loosens the soil around the roots of Stellera chamaejasme, and then cooperates with the cutting structure to cut the bottom of the location where the roots of Stellera chamaejasme are located, so as to completely separate the soil at the roots of Stellera chamaejasme from the outside, facilitate the removal of the roots of Stellera chamaejasme, prevent the roots of Stellera chamaejasme from being damaged, improve the efficiency of Stellera chamaejasme harvesting, and make the prevention and control effect better; the setting of the mobile structure is convenient for adjusting the position of the pressing plate and the wheel. When the pressing plate contacts the ground, it is convenient to step on the pressing plate to make the overall stability better. When the wheel contacts the ground, it is convenient to move the entire device, and improve the operational flexibility. Compared with the existing technology, the invention patent with Chinese patent number CN118216288B solves the problems that the existing devices have a large excavation area during the excavation process, are highly destructive to the grassland, have low efficiency in loosening the soil, and when the excavation depth is not enough, the roots of Stellera chamaejasme cannot be completely removed. The roots of Stellera chamaejasme are easily damaged during the excavation process, which is not conducive to its complete removal and affects the management efficiency.

[0004] However, in actual use of the above-mentioned device, multiple pesticide applications are required to remove the seeds of Stellera chamaejasme in the soil, and the methods of pesticide application are different at different stages. The existing device has a single pesticide application method, which is difficult to adjust in different stages of treatment. Different equipment needs to be replaced and used, and the use effect is not good. Therefore, a device for removing the seeds of Stellera chamaejasme in the soil is proposed.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0032] like Figure 1-Figure 8 As shown, the present invention proposes a device for removing seeds of Stellera chamaejasme in the soil, comprising a removing frame 1, a medicine storage box 5 is fixedly connected to the upper part of the removing frame 1, a stirring assembly is arranged on the upper part of the medicine storage box 5, three pressure pumps 12 are fixedly connected to the bottom of the medicine storage box 5, an adjusting shell 13 is arranged at the lower part of the pressure pump 12, a nozzle is opened at the bottom of the adjusting shell 13, an adjusting mechanism is arranged inside the adjusting shell 13, and the adjusting mechanism switches the application mode by adjusting the flow rate of the nozzle of the adjusting shell 13.

[0033] The bottom of the pressure pump 12 is fixedly connected with a blowing mechanism, which delivers air to the bottom. Two transmission mechanisms are symmetrically arranged at the front end of the cleaning frame 1. A cross frame 3 is arranged at the lower part of the transmission mechanism, and the cross frame 3 can be driven to move up and down through the transmission mechanism.

[0034] A connecting pipe 14 is fixedly connected to the bottom of the pressure pump 12, and an adjusting shell 13 is fixedly connected to the lower part of the connecting pipe 14. The connecting pipe 14 penetrates into the adjusting shell 13, and the bottom contacts the upper surface of the movable baffle 22. The adjusting mechanism includes a fourth motor 18 arranged inside the adjusting shell 13, and a first gear 19 is arranged at the output end of the fourth motor 18. The first gear 19 is meshingly connected to the second gear 20, and five eccentric shafts 21 are fixedly connected to the bottom of the second gear 20. The bottom of the eccentric shaft 21 is rotatably connected to the movable baffle 22, and the lower part of the movable baffle 22 is rotatably connected to the adjusting shell 13.

[0035] The blowing mechanism includes a blowing shell 15 fixedly connected to the bottom of the booster pump 12 , two third motors 16 are arranged inside the blowing shell 15 , fan blades 17 are arranged at the output end of the third motor 16 , and a filter screen 23 is fixedly connected to the bottom of the blowing shell 15 .

[0036] A feeding port is arranged on the upper part of the medicine storage box 5, and a sealing cover 24 is threadedly connected to the upper part of the feeding port. The stirring assembly includes a second motor 10 arranged on the top of the medicine storage box 5, and a stirring rod 11 is arranged at the output end of the second motor 10. Four wheels are arranged at the bottom of the cleaning frame 1. The wheels are flexible in rotation, and an anti-slip surface is arranged on the surface of the wheels to adapt to soils of different geology.

[0037] In this embodiment, before using the device, liquid medicine and sufficient water can be added into the medicine storage box 5 through the feeding port provided on the medicine storage box 5, and then the medicine storage box 5 is sealed through the sealing cover 24, and then the second motor 10 is started, and the stirring rod 11 provided inside the medicine storage box 5 is driven to rotate by the second motor 10. The rotation of the stirring rod 11 can drive the medicine and water inside the medicine storage box 5 to be fully mixed to form the medicine. After the mixing is completed, the first gear 19 can be driven to rotate by starting the fourth motor 18 inside the adjustment shell 13. The rotation of the first gear 19 can drive the meshing second gear 20 to rotate. The rotation of the second gear 20 can drive the five eccentric shafts 21 fixedly connected at the bottom to rotate. The rotation of the eccentric shaft 21 can drive the rotatably connected movable baffle 22 to rotate as well. By adjusting the rotation angle of the five movable baffles 22, the nozzle flow rate at the bottom of the adjustment shell 13 can be adjusted.

[0038] In the early stage of pesticide application, some Stellera chamaejasme plants grow on the soil surface. At this time, direct irrigation makes it difficult for the pesticide to penetrate into the soil and act on the Stellera chamaejasme seeds. The fourth motor 18 can be used to control the nozzle flow rate at the bottom of the outer shell 13 to decrease, and the pesticide in the medicine storage box 5 is pressurized by the pressure pump 12 and enters the connecting pipe 14. The high-pressure pesticide is sprayed out through the small nozzle to form a spray. The pesticide can effectively act on the plant surface through spraying, thereby improving the cleaning effect. Moreover, when spraying the pesticide, the third motor 16 inside the blowing shell 15 can be started to drive the fan blades 17 to rotate, thereby blowing the air flow to assist the pesticide spraying, which can further improve the effect of the pesticide. After the plants are cleaned, the nozzle flow rate is increased, and the spraying mode is switched to irrigation. The irrigation pesticide can penetrate deep into the soil to clean the Stellera chamaejasme seeds inside the soil. By adjusting different pesticide application methods, the device can adapt to different prevention and control stages, effectively improving the use effect of the device. Example

[0039] like Figure 1-Figure 8 As shown, the transmission mechanism includes a transmission housing 2 fixedly connected to the front end of the cleaning frame 1, a first motor 6 is arranged at the bottom of the transmission housing 2, a screw rod 8 is arranged at the output end of the first motor 6, the screw rod 8 is rotationally connected to the transmission housing 2, the screw rod 8 is threadedly connected to a transmission plate 7, the transmission plate 7 is fixedly connected to a cross frame 3 away from the transmission housing 2, and a plow 4 is arranged at the bottom of the cross frame 3.

[0040] Four sliders 9 are fixedly connected to the side of the transmission plate 7 close to the transmission housing 2. The four sliders 9 are symmetrically arranged in two rows. The slider 9 is slidably connected to the limiting slide rail 25 on the side away from the transmission plate 7. The limiting slide rail 25 is fixedly connected to the transmission housing 2. There are six plowshares 4 arranged at the bottom of the cross frame 3. The six plowshares 4 are equidistantly arranged. The plowshares 4 have sharp blades that can easily break the soil.

[0041] In this embodiment, when the device sprays pesticides, the horizontal frame 3 is controlled to rise by the adjusting mechanism, thereby ensuring that the plowshare 4 will not turn over the soil to break the plants, leaving the roots of the plants inside the soil to pollute the soil. When watering and applying pesticides, the first motor 6 can be started, and the first motor 6 drives the screw rod 8 to rotate. The rotation of the screw rod 8 drives the threaded transmission plate 7 to move downward. During the movement of the transmission plate 7, the four fixedly connected sliders 9 synchronously slide along the limiting slide rails 25, effectively ensuring the stability of the transmission plate 7 during movement. The movement of the transmission plate 7 can drive the fixedly connected horizontal frame 3 to move downward, so that the plowshare 4 set at the bottom of the horizontal frame 3 penetrates into the soil. When the cleaning frame 1 moves, the plowshare 4 can turn over the soil on the moving path of the cleaning frame 1, thereby improving the effect of the agent penetrating into the soil, ensuring that the agent can effectively kill the Daphne chamaejasme seeds inside the soil.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
