Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grass seed planters, in particular to a blockage prevention mechanism for a grass seed planter. Background Technique
[0002] A planter is a planting machine that takes crop seeds as the sowing object. Planters for a certain type or kind of crop are often named after the crop type, such as a grain drill, a corn hill-drop planter, a cotton planter, a forage broadcaster, etc. In the 1st century BC, the drill was popularized in China, which is the world's earliest drill tool and is still used in dry farming areas in the north today.
[0003] There is no blockage prevention component in the grass seed placement hopper of the existing grass seed planter. Therefore, when there are a large number of grass seeds and some grass seeds are adhered, it may cause the leaking grass seeds to be blocked at the leakage port of the placement hopper and the pipe connection. Since the placement hopper is full of grass seeds, it is impossible to judge the blockage position and reason. Therefore, the traditional poking method cannot effectively clear the blockage and may also cause damage to the components of the planter. Therefore, the existing grass seed planter is inconvenient to use. Content of the Utility Model
[0004] The purpose of the utility model is to solve the defect that the grass seed planter in the prior art cannot be conveniently and effectively cleared of blockage during sowing, and to provide a blockage prevention mechanism for a grass seed planter.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: A blockage prevention mechanism for a grass seed planter, including: a placement hopper, a blockage clearing mechanism is provided at the top of the placement hopper. The blockage clearing mechanism includes a rotating rod, a connecting rod is fixedly connected to the bottom of the rotating rod, a rotating blade is fixedly connected to one end of the connecting rod away from the rotating rod, a sleeve ring is sleeved on the outer surface of the connecting rod, the sleeve ring is fixedly connected to the connecting rod, a scraping block is fixedly connected to the outer surface of the sleeve ring, a rotating ring is sleeved on the outer surface of the rotating rod, the rotating ring is fixedly connected to the rotating rod, and a rotating handle is fixedly connected to one end of the rotating rod away from the connecting rod.
[0006] As a preferred implementation manner, an adjusting mechanism is provided at the top of the placement hopper. The adjusting mechanism includes a cross bar, a threaded pipe penetrates through the inside of the cross bar, the threaded pipe is fixedly connected to the cross bar, a threaded column is sleeved inside the threaded pipe, and the threaded column is threadedly connected to the threaded pipe.
[0007] As a preferred implementation manner, the rotating rod penetrates through the inside of the threaded column, and the rotating rod is rotatably connected to the threaded column. The rotating ring is placed in a rotating groove opened inside the threaded column.
[0008] As a preferred implementation manner, the rotating ring is rotatably connected to the inner wall of the threaded column, and a limiting ring is sleeved on the outer surface of the threaded column.
[0009] In a preferred embodiment, the limiting ring is fixedly connected to the threaded post, and a turntable is provided at the top of the limiting ring, which is sleeved on the outer surface of the threaded post.
[0010] In a preferred embodiment, both ends of the crossbar are provided with hexagonal bolts, which penetrate the crossbar and the interior of the placement bucket.
[0011] In a preferred embodiment, the hexagonal bolt is slidably connected to the crossbar and threadedly connected to the placement bucket.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] This invention, by incorporating a clearing mechanism, allows the grass seed seeder to promptly clear blockages during sowing, ensuring continuous sowing and preventing the amount of grass seeds leaking below a predetermined level due to blockages. This results in more uniform sowing. The inclusion of rotating blades and scraping blocks ensures that the openings of the placement hopper and pipe connections are cleaned effectively and promptly, preventing seeds from sticking together and failing to leak. Furthermore, an adjustment mechanism allows for the adjustment of the clearing mechanism's position, ensuring it does not affect the normal leakage rate of the placement hopper. The clearing mechanism is only lowered to a suitable position when the placement hopper is blocked. A limiting ring allows for adjustment of the clearing mechanism's position within the seed-filled placement hopper. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1
[0025] like Figures 1-3 As shown, this utility model provides a technical solution: an anti-clogging mechanism for a grass seed planter, comprising: a placement hopper 1, a clearing mechanism 2 at the top of the placement hopper 1, the clearing mechanism 2 including a rotating rod 21, a connecting rod 22 fixedly connected to the bottom of the rotating rod 21, a rotary blade 23 fixedly connected to the end of the connecting rod 22 away from the rotating rod 21, a collar 24 sleeved on the outer surface of the connecting rod 22, the collar 24 being fixedly connected to the connecting rod 22, a scraping block 25 fixedly connected to the outer surface of the collar 24, a rotating ring 26 sleeved on the outer surface of the rotating rod 21, the rotating ring 26 being fixedly connected to the rotating rod 21, and a handle 27 fixedly connected to the end of the rotating rod 21 away from the connecting rod 22.
[0026] In this embodiment, by setting up a blockage-clearing mechanism 2, the blockage at the outlet and pipe connection of the seeder's hopper 1 can be cleared, preventing the hopper 1 from being unable to be cleared accurately and effectively when it is full of grass seeds. The rotating rod 21 can drive the connecting rod 22 to rotate at the same time as the rotating rod 21 rotates, so that the blade 23 and the scraper block 25 can separate the seeds adhering to the pipe connection and outlet of the hopper 1, thereby achieving the purpose of clearing the blockage. The rotating ring 26 is set up and placed in the rotating groove opened inside the threaded column 33, so that the rotating rod 21 and the connecting rod 22 can rotate stably under the action of the rotating ring 26.
[0027] Example 2
[0028] like Figure 1 , Figure 2 and Figure 4As shown, the top of the placement hopper 1 is provided with an adjustment mechanism 3. The adjustment mechanism 3 includes a crossbar 31, through which a threaded tube 32 passes. The threaded tube 32 is fixedly connected to the crossbar 31. A threaded post 33 is sleeved inside the threaded tube 32. The threaded post 33 is threadedly connected to the threaded tube 32. A rotating rod 21 passes through the inside of the threaded post 33. The rotating rod 21 is rotatably connected to the threaded post 33. A rotating ring 26 is placed in a rotating groove opened inside the threaded post 33. The rotating ring 26 is rotatably connected to the inner wall of the threaded post 33. A limiting ring 34 is sleeved on the outer surface of the threaded post 33. The limiting ring 34 is fixedly connected to the threaded post 33. A turntable 35 is provided at the top of the limiting ring 34. The turntable 35 is sleeved on the outer surface of the threaded post 33. Hexagonal bolts 36 are provided at both ends of the crossbar 31. The hexagonal bolts 36 pass through the crossbar 31 and the interior of the placement hopper 1. The hexagonal bolts 36 are slidably connected to the crossbar 31. The hexagonal bolts 36 are threadedly connected to the placement hopper 1.
[0029] In this embodiment, by setting the adjustment mechanism 3, the unblocking mechanism 2 can be lowered to a suitable position when a blockage occurs. By rotating the threaded column 33, which is threadedly connected to the threaded tube 32, the unblocking mechanism 2 can be slowly lowered while the threaded column 33 is rotating. In addition, a limit ring 34 is set to determine the position of the unblocking mechanism 2, so that the rotary blade 23 and the scraper block 25 can be in the appropriate position.
[0030] Working principle:
[0031] like Figures 1-4 As shown, in use, the crossbar 31 can be connected to the placement hopper 1 first. A hexagonal bolt 36 is passed through the crossbar 31 and threaded into the placement hopper 1. Then, grass seeds are poured into the placement hopper 1, and the seeder can be started to sow the grass seeds. If blockages occur at the pipe connection and leak point of the placement hopper 1, the unblocking mechanism 2 can be lowered using the adjusting mechanism 3. At this time, the turntable 35 is rotated, causing the threaded column 33 to rotate. Since the threaded column 33 is threadedly connected to the threaded pipe 32, the threaded column 33 moves downwards while rotating. Move the device until the limiting ring 34 contacts the threaded pipe 32. At this point, the entire unblocking mechanism 2 is in the correct position. Then, turn the handle 27 to drive the rotating rod 21 and connecting rod 22 to rotate. With the cooperation of the rotating ring 26, the connecting rod 22 can stably drive the rotating blade 23 and scraper block 25 to rotate. The rotating blade 23 unblocks the pipe connection, and the scraper block 25 unblocks the leak, so that the drainage function of the placement hopper 1 is normal. Then, turn the turntable 35 in the opposite direction to raise the entire unblocking mechanism 2 so that it will not affect the normal drainage of grass seeds by the placement hopper 1.
[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
