Description

Technical Field

[0001] The invention relates to the technical field of grass seed sprayers, in particular to a high-efficiency grass seed sprayer for repairing rodent-infested land. Background Art

[0002] A grass seed sprayer is a highly efficient greening device, primarily used to mix and evenly spray grass seeds, soil matrix, fertilizer, water-retaining agent, adhesive, and other materials onto the slope or land to be greened. Using the principle of jet mixing, the grass seed sprayer mixes the grass seeds into a tank filled with a certain proportion of water, fiber mulch, adhesive, water-retaining agent, and fertilizer, stirring the mixture evenly to form a slurry. This slurry is then transported to the spray nozzle using a centrifugal pump or slurry pump and sprayed onto the surface of the soil to be sown, forming a uniform layer of slurry grass seeds. Excess water in the slurry seeps into the soil, while the water-retaining fibers and colloids form a semi-permeable, moisture-retaining surface layer that aids seed germination and growth. However, in the process of restoring and treating land infested by rodents, this device is required for land repair.

[0003] According to the announcement number "CN218998825U" published on the China Patent Network, it is a "grass seed spraying equipment suitable for ecological restoration between hills", which includes a frame, a mixing chamber on one side of the frame and a driving device on the other side. The mixing chamber is provided with a stirring mechanism; the driving device includes a fuel engine, a power supply, a starting motor, a gearbox and a mud pump. A spraying ball valve is provided on the top of the frame, and the upper end of the spraying ball valve is connected to a spray gun through a spray hose. A discharge pipe is connected between the side of the mixing chamber and the inlet of the mud pump, and a feeding pipe is connected between the mud pump outlet and the spraying ball valve. A reflux device is connected between the feeding pipe and the mixing chamber. This utility model is suitable for grass seed spraying equipment for ecological restoration between hills. It has a reasonable structure, is easy to use, and operates stably. It adopts dual stirring forms of mechanical stirring and circulating reflux stirring, which is sufficient to ensure that the mixed slurry is in a suspended and uniform state during the spraying process and can evenly spray the mixed raw materials.

[0004] Although the above patent can improve the efficiency of spraying, the existing grass seed spraying machines first pour the raw materials into the device and then mix them. After the mixing is completed, spraying can be carried out. When the materials are used, the device needs to be shut down and the raw materials need to be poured in again for mixing. The spraying cannot be carried out continuously, thereby reducing the overall spraying efficiency. For this reason, we provide a high-efficiency grass seed spraying machine for rodent-infested land restoration to solve the above problems. Summary of the Invention

A second drive motor 20 is installed on one side of the fixing seat 19, and the output end of the second drive motor 20 is fixedly connected to a rotating shaft 17. The switching assistant also includes a hose 22 fixedly connected between the connecting block 11 and the connecting shell 6, and the hose 22 is arranged on the outside of the winding rope 18. A connecting spring 23 is installed between the connecting block 11 and the connecting shell 6, and one side of the connecting shell 6 is fixedly connected. A rectangular rod 24 is connected, and the connecting block 11 is slidably connected to the outer wall of the rectangular rod 24. The rectangular rod 24 is arranged on the inner side of the hose 22. A limiting slide matching the rectangular rod 24 is provided on the inner side of the connecting block 11. The auxiliary flushing mechanism includes a plurality of rings 30 rotatably connected to the inner side of the shielding sleeve 8. A vent groove 36 is provided inside each ring 30. Every two rings 30 are fixedly connected by a connecting pipe 35, and the two ends of the connecting pipe 35 respectively pass through the inside of a vent groove 36. The plurality of rings 30 are arranged at equal distances laterally on the inner side of the shielding sleeve 8. A plurality of nozzles 31 are installed on the inner side of the ring 30, and each The air inlets of the nozzles 31 are all connected to the interior of the ventilation groove 36. Multiple nozzles 31 are equidistantly distributed around the inner side of the ring 30. A through hole 21 is opened on one side of the shielding sleeve 8 and extends to the outside. The nozzles 31 are initially arranged on one side of the through hole 21, and the diameter of the through hole 21 is larger than the diameter of the nozzles 31.

A first drive motor 15 is installed on one side of the fixing ring 9. The output end of the first drive motor 15 is connected to a first spur gear 14 that meshes with the spur gear ring 16.

[0033] A circular ring 30 at the very end is connected to an external hose through a bellows, and the hose passes through the outside of the machine base 1 and is connected to an external air pump. There is no filter screen at both ends of the filter sleeve 12, but there is a filter screen in the middle. When the mixed material is discharged through the guide tube 7, it is filtered through one of the opened filter sleeves 12 to filter the agglomerated material. After one of them has been used for a period of time, the second drive motor 20 can be started intermittently. The output end of the second drive motor 20 drives a rotating shaft 17 to rotate, thereby reeling in a winding rope 18. At the same time, the rotation of the rotating shaft 17 drives a second spur gear 38 to rotate, thereby driving The other second spur gear 38 is driven to rotate the other rotating shaft 17, thereby releasing the other winding rope 18, thereby pulling one shielding sleeve 8 to release the other shielding sleeve 8, and the released shielding sleeve 8 can shield the filter sleeve 12, so that when one filter sleeve 12 is shielded, the external air pump delivers air to the interior of the multiple rings 30 through the connecting pipe 35, and sprays high-pressure gas through the nozzle 31 to impact the inner mesh of the filter sleeve 12 and the material agglomerated therein, so that the agglomerated material can be dispersed, and at the same time, the blocked filter sleeve 12 is cleaned, thereby ensuring the smooth filtration of the filter sleeve 12;

[0034] When the filter sleeve 12 is filtering, the first drive motor 15 is started, and the output end of the first drive motor 15 drives the first spur gear 14 to rotate, thereby driving the spur gear ring 16 to drive the filter sleeve 12 to rotate in a circle through the connecting ring 13, so that centrifugal force is generated inside the filter sleeve 12 to disperse the clumped materials. When the filter sleeve 12 is covered, the filter sleeve 12 mesh can be fully flushed through the circumferential rotation of the filter sleeve 12 and the nozzle 31, thereby improving the cleaning effect of the inside of the filter sleeve 12.

[0035] See also Figures 7 and 8 , a replacement component is located on the inner side of the shielding sleeve 8 and is used to adjust the position of the flushing auxiliary mechanism. The replacement component includes a fixed plate 32 fixedly connected to the inner side of the shielding sleeve 8, a connecting block 33 is fixedly connected to one side of the circular ring 30, and a ball 34 is embedded in the front end of the connecting block 33.

A slide groove 26 is provided on the inner side of the shielding sleeve 8, and a power ring 25 is slidably connected to the inner side of the slide groove 26. One end of the power ring 25 is fixedly connected to a connecting rod 27, and one end of the connecting rod 27 passes through the inner side of the shielding sleeve 8 and is fixedly connected to the arc-shaped oblique block 29. A power spring 28 is installed between the slide groove 26 and the power ring 25.

[0036] When the shielding sleeve 8 moves toward the filter sleeve 12, it drives the shielding sleeve 8 to move synchronously. When one end of the power ring 25 contacts the fixing ring 9 and encounters resistance, the power ring 25 is pushed to slide relative to the inner side of the shielding sleeve 8, so that the arc-shaped inclined block 29 is moved away from the side of the ball 34, so that the arc-shaped spring 37 is no longer subject to external resistance and pushes the connecting block 33 to drive the ring 30 to reset, so that multiple rings 30 rotate synchronously. When the ring 30 stops rotating, the nozzle 31 is aligned with the through hole 21. The above steps are reversed to make the nozzle 31 stored in the inner side of the shielding sleeve 8 when not in use and aligned for protection, thereby avoiding blockage of the nozzle 31 port, thereby improving the overall practicality of the device.
