DETAILED DESCRIPTION

[0017] 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.

[0018] Embodiment 1: like Figure 1-Figure 9As shown, an embodiment of the present invention provides a forage grass seed planting device for grassland sand fixation, comprising a pulling frame 1 and a seed box 2, wherein the pulling frame 1 is fixedly connected to the front side of the seed box 2, and the front side of the pulling frame 1 comprises a fixing hook connected to a tractor, wherein the forage grass seed planting device for grassland sand fixation is moved by pulling the tractor, and a placing frame 5 is fixedly connected to the rear side of the seed box 2, the placing frame 5 is U-shaped, and both ends of the U-shape are fixedly connected to the seed box 2, and the rear side of the placing frame 5 comprises a supporting plate for placing forage grass, which is similar to a flatbed truck bucket, and first supporting plates are fixedly connected to both ends of the lower side of the placing frame 5; A pressure roller 4 is provided at the lower part of the placement frame 5, and the pressure roller 4 includes a roller shaft rotatably connected to the placement frame 5, and a support rod is fixedly connected to the outer side of the roller shaft in a radial shape, and a cylindrical wire mesh is fixedly connected to the end of the support rod away from the roller shaft, and a dial wheel 7 is fixedly connected to the outer side of both ends of the pressure roller 4, and a front wheel 8 is provided at the lower part of the pulling frame 1. In the above, the pressure roller 4 is rotatably connected between the two first support plates, that is, the two ends of the roller shaft are rotatably connected to the two first support plates, and the steel wire mesh can be used to reduce the sand residue and reduce the resistance of the grassland sand fixation forage seed planting device to move. The above-mentioned dial wheel 7 includes an outer ring fixedly connected to the pressure roller 4, and the outer side of the outer ring is fixedly connected with a dial block at equal intervals, and the outermost circle of support rods is supported on the inner side of the outer ring, so as to ensure that the pressure roller 4 can travel normally; The inner side of the placing rack 5 is provided with a pressing assembly cooperating with the thumbwheel 7, and the inner side of the placing rack 5 is fixedly connected with a guide frame 9 tilted downward toward one side of the seed box 2, that is, the guide frame 9 is fixedly connected to the inner side of the U-shaped part, specifically fixedly connected to the front side of the support plate, and the end of the guide frame 9 away from the placing rack 5 is bent upward. Through the curved design of the front end of the guide frame 9, it is convenient for workers to prevent the forage from the support plate of the placing rack 5 onto the guide frame 9 and slide down along the guide frame 9 so that it will not fall at the front end of the guide frame 9; The two levers 3 are connected to the rear edge of the lever 5 and the levers 3 are engaged with the levers 3 on the left and right sides of the levers 3. The levers 3 are engaged with the levers 7 on the right and left sides of the levers 3. The shifting block of the wheel 7 pushes the shifting frame 3, so that the front end of the shifting frame 3 is tilted, and then the first spring 16 is gradually compressed, and a cross bar 20 is fixedly connected between the front ends of the two shifting frames 3, and a second support plate group is included on the side of the cross bar 20 facing the seed box 2, and a shifting rod 10 corresponding to the position of the guide head 21 is rotatably connected in the second support plate group of the cross bar 20. The number of the second support plates corresponding to the above-mentioned second support plate group is two, and the front end of the shifting rod 10 includes a fork groove arranged in the length direction of the seed box 2, and a second spring 19 is fixedly connected between the shifting rod 10 and the guide head 21. In the above, the shifting rod 10 swings with the shifting frame 3, so that the forage grass sliding down from the guide frame 9 is pushed downward by the fork groove of the shifting rod 10; A seed roller 18 including a seed groove is rotatably provided inside the seed box 2. A baffle 17 is fixedly connected to the inner wall of the seed box 2 and located on the side close to the pulling frame 1. The baffle 17 is made of silicone rubber. The side of the baffle 17 away from the fixed connection end is pressed on the upper side of the seed roller 18. In the above, the baffle 17 can greatly reduce the position of the seed roller 18 rotating to enter the seed box 2. A transmission component 15 is provided between the front wheel 8 and the seed roller 18 to realize the synchronous rotation of the two. The position of the seed groove corresponding to the inside of the seed box 2 is provided with a seed outlet 23. The outside of the seed box 2 is fixedly connected with a seed guide bucket 11 connected with the seed outlet 23. In the above, the seed groove of the seed roller 18 is brought into the seed outlet 23 and then enters the seed guide bucket 11. The transmission component 15 includes a first sprocket, a second sprocket and a chain. The chain is meshed with the outer sides of the first sprocket and the second sprocket. The first sprocket is synchronously driven with the front wheel 8, and the second sprocket is synchronously driven with the seed roller 18. The middle part of the seed box 2 includes a accommodating groove for accommodating the second sprocket. In the above, the first sprocket, the second sprocket and the chain can be replaced with a belt and two pulleys. Since the principles of the two are similar, they are not described in detail. There is a swing frame 12 at both ends of the seed box 2, and a push-pull power member 14 is rotatably connected between the pulling frame 1 and the swing frame 12. A plurality of guide heads 21 are fixedly connected to the lower part of the swing frame 12. The guide heads 21 are distributed in the same number of weeks as the seed grooves. A plowshare 13 is fixedly connected to the front side of the guide head 21. The middle part of the upper side of the plowshare 13 is a pyramid with a pointed tip upward. The lower side of the rear end of the plowshare 13 includes an arc guide surface. In the above, the swing frame 12 is driven to swing forward by the retraction of the push-pull power member 14, thereby driving the plowshare 13 to penetrate into the seed box. On the grass surface covered with sand, the shape design of the plowshare 13 can greatly reduce the height of the grass being lifted up. At the same time, the sand can be guided to under the broken grass through the guide arc surface, thereby achieving sand fixation in the original grass. The effect is better when the original grass has abundant underground grass roots. The other end of the seed guide bucket 11 is correspondingly connected to the guide head 21. The guide head 21 is provided with a discharge trough that passes downward. The output end of the pressing assembly corresponds to the position of the discharge trough. The above-mentioned discharge trough is for facilitating the falling of forage seeds.

[0019] The push-pull power member 14 uses any one of an electric push rod, a hydraulic rod, an electric cylinder, and a pneumatic cylinder. The push-pull power member 14 is arranged obliquely and is connected to a controller, so that the controller can be used to control the telescopic state of the push-pull power member 14.

[0020] A guide groove 22 is provided forwardly through the lower end of the guide head 21, the width of the lever 10 is consistent with the width of the guide groove 22, the guide groove 22 is connected to the discharge chute, and the front end of the lever 10 includes a front guide opening that passes downward, and the front guide opening is connected to the fork groove. In the above, the front guide opening can prevent the lever 10 from swinging into the guide groove 22 and clamping the grass seeds falling from the guide groove 22.

[0021] Working principle: After the pulling frame 1 is installed on the tractor, the push-pull power member 14 is shortened to pull the swing frame 12 to swing forward, so that the plowshare 13 is driven into the ground. Since the guide head 21 is located at the rear side of the plowshare 13, the lower end of the guide head 21 can also extend into the ground. When the tractor drives the grassland sand fixation forage seed planting device to move, the worker places the forage on the placement frame 5 along the guide frame 9, and then the forage falls along the guide frame 9. As the grassland sand fixation forage seed planting device moves, the front wheel 8 is driven to rotate the seed roller 18 through the transmission assembly 15. At the same time, it drives the dial wheel 7 to rotate. The dial wheel 7 intermittently pushes the dial pressure frame 3 through the shift block to cooperate with the deformation of the first spring 16 to make the dial rod 10 swing, and then the dial rod 10 pushes the grass falling along the guide frame 9 into the ground broken by the plowshare 13 from the fork groove. The second spring 19 can make the dial rod 10 close to the guide head 21, so that the guide head 21 will not be unable to contact the dial rod 10 as the swing frame 12 swings. During the process, the grass seeds enter the seed outlet 23 from the seed box 2 as the seed roller 18 rotates, and then fall from the guide head 21 through the seed guide bucket 11.

[0022] Embodiment 2: The difference between this embodiment and the first embodiment is that a connecting rod is fixedly connected between adjacent levers 10, and the front end of the lever 10 and the side facing the guide head 21 include an arc surface. In the above, the connecting rod is used to facilitate the synchronous swinging of each lever 10, and the arc surface at the front end of the lever 10 allows the fallen grass seeds and stones in the falling direction of the lever 10 to be pushed downward through the guide groove 22, preventing the grass from being effectively pushed into the plowed grassland.

[0023] Embodiment three: The difference between this embodiment and the second embodiment is that a counterweight rear wheel 6 is fixedly connected to the outer side surface of the pressure roller 4 and located in the middle, and the outer cylindrical surface of the counterweight rear wheel 6 coincides with the outer circumferential surface of the pressure frame 3. By adding the counterweight rear wheel 6 to the pressure roller 4, the pressure roller 4 shakes less when walking on an uneven bottom surface, which can greatly reduce the fall of forage from the guide frame 9.

[0024] 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.
