Description

Technical Field

[0001] The utility model relates to the technical field of sowing devices, in particular to a grass seed sowing device for vegetation reconstruction. Background Art

[0002] In the process of vegetation reconstruction, the most important step is grass seed sowing. Currently, grass seed sowing devices are usually used instead of manual sowing to improve sowing efficiency.

[0003] For example, CN 214708681 U discloses a grass seed sowing device for vegetation reconstruction, which includes a storage box with a feed box welded to the top of the inner wall of the storage box. Connecting pipes are symmetrically fixedly connected to the bottom of the feed box on both sides. Support pipes are symmetrically connected to the bottom of the inner wall of the storage box, and a sowing mechanism is installed on one end of the support pipe. The sowing mechanism includes a guide box, a discharge barrel, a guide rod, a slider, a rotating rod, a positioning pin, a tension spring, and an inclined plate. When the positioning pin contacts the soil, it slides on the outer end of the discharge barrel. When the slider slides to the top of the guide rod, the positioning pin is restricted, thereby facilitating the positioning pin's insertion into the soil for drilling. At the same time, the top of the positioning pin contacts the bottom of the inclined plate, causing the two positioning pins to separate, and the grass seed slides out of the discharge barrel and out of the positioning pin. This cooperates with the rotation of the material guide box and improves the sowing efficiency of the grass seed. However, the following problem still exists: only one row of grass seed sowing can be completed during the movement, and the sowing efficiency is still low. Utility Model Content

[0004] The purpose of the utility model is to provide a grass seed spreading device for vegetation reconstruction with a reasonable structure and reliable use to solve the above problems, which can complete the spreading work of multiple rows of grass seeds during the walking process and significantly improve the spreading efficiency.

[0005] The technical solution of the utility model is:

The linkage plate at the lower end of the telescopic part of the movable telescopic rod, a plurality of discharge risers connected to the lower surface of the linkage plate, a left return spring connected between the left positioning plate and the linkage plate, and a right return spring connected between the right positioning plate and the linkage plate.

The outer diameter of the discharge riser is equal to the inner diameter of the circular positioning tube. The lower part of the outer wall of the discharge riser is provided with a discharge hole group blocked by the circular positioning tube.

[0007] In the above-mentioned grass seed spreading device for vegetation reconstruction, the discharge hole group consists of a plurality of radial through holes evenly distributed around the center line of the discharge riser, and the aperture of the radial through holes is larger than the outer diameter of one grass seed and smaller than the sum of the outer diameters of two grass seeds.

Then, the seeds fall from the lower end of the discharge vertical pipe into the pre-dug sowing pit. Then, under the action of the left and right return springs, the linkage plate and each discharge vertical pipe return to their original position. When they reach the top of the next row of sowing pits, the left and right electric telescopic rods pull the linkage plate and each discharge vertical pipe upward again, repeating the above sowing action. This utility model has a simple structure and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The utility model is described in detail according to the accompanying drawings.

[0017] like Figure 1 、 Figure 2As shown, the grass seed spreading device for vegetation reconstruction includes a rectangular fixed shell 1 and a spreading mechanism for being arranged on a frame.

[0018] A storage box 5 is fixed inside the rectangular fixed shell 1. A plurality of discharge hoppers 11 are arranged in parallel at the lower part of the storage box 5 along the length direction of the rectangular fixed shell 1. The lower end of each discharge hopper 11 is provided with a circular positioning tube 14. The spreading mechanism includes a left positioning plate 2 and a right positioning plate 9 provided on the left and right sides of the upper edge of the storage box 5, a left electric telescopic rod 3 and a right electric telescopic rod 8 fixed to the left positioning plate 2 and the right positioning plate 9, a linkage plate 6 connected to the lower end of the telescopic portion of the left and right electric telescopic rods, a plurality of discharge risers 12 connected to the lower surface of the linkage plate 6, a left return spring 4 connected between the left positioning plate 2 and the linkage plate 6, and a right return spring 7 connected between the right positioning plate 9 and the linkage plate 6. The number of the discharge riser 12 and the circular positioning tube 14 are equal and one-to-one corresponding. The lower end of the discharge riser 12 passes through the circular positioning tube 14 to reach the outside of the circular positioning tube. The outer diameter of the discharge riser 12 is equal to the inner diameter of the circular positioning tube 14. The lower part of the outer wall of the discharge riser 12 is provided with a discharge hole group 13 blocked by the circular positioning tube 14.

[0019] In this embodiment, the discharge hole group 13 consists of multiple radial through-holes evenly distributed around the centerline of the discharge standpipe 12. The diameter of these radial through-holes is larger than the outer diameter of one grass species and smaller than the sum of the outer diameters of two grass species. The left return spring 4 surrounds the outer side of the telescopic portion of the left electric telescopic rod 3, while the right return spring 7 surrounds the outer side of the telescopic portion of the right electric telescopic rod 8. Horizontal connecting plates 10 are provided at the lower ends of the left and right side walls of the rectangular fixed housing 1. These horizontal connecting plates 10 are provided with a group of mounting holes.

[0020] Working principle:

[0021] Before work, the device is fixed to a movable frame using the mounting hole group on the horizontal connecting plate 10. The front of the frame is provided with a pit opening mechanism corresponding to each discharge riser 12 of the device, and the rear is provided with a soil covering mechanism corresponding to each discharge riser 12 of the device.

[0022] During operation, the device, driven by the frame, moves forward. When it reaches above a pre-set seeding hole, the left and right electric telescopic rods 3 and 8 are activated, pulling the linkage plate 6 and the various discharge pipes 12 upward. This allows the grass seeds in the discharge hopper 11 to pass through the discharge holes 13 and into the discharge pipes 12. From the lower ends of the discharge pipes 12, the seeds fall into the pre-dug seeding hole. The linkage plate 6 and the various discharge pipes 12 are then reset by the left and right return springs 4 and 7, and the discharge holes 13 are again blocked by the circular positioning tubes 14, preventing seed from falling. When it reaches above the next row of seeding holes, the left and right electric telescopic rods 3 and 8 again pull the linkage plate 6 and the various discharge pipes 12 upward, repeating the above spreading process until the grass seeds are spread across multiple rows and columns in one stroke.

[0023] The above detailed description of the embodiments of the present invention is intended to be a preferred embodiment of the present invention and should not be construed as limiting the scope of implementation of the present invention. Any equivalent changes and improvements made within the scope of the present invention shall still fall within the scope of this patent.
