Technical Field
[0001] The utility model relates to the technical field of seed meters, in particular to a brush-type seed meter. Background Art
[0002] A seed meter is a machine for automatic sowing. While the seeding machine is moving, seeds are discharged from the discharge port and then automatically buried by filling soil, so as to achieve automatic sowing. Compared with traditional manual sowing, it has higher efficiency and better sowing effect, so it is widely promoted.
[0003] At present, there are various types of seed meters on the market. Most of the internal mechanical structures of seed meters are complex and there are many precision parts. Therefore, the production and maintenance costs of seed meters are extremely high. In order to facilitate the stable seeding of seed meters while reducing the production and maintenance costs of seed meters, we propose a brush-type seed meter. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the defects existing in the prior art and propose a brush-type seed meter.
[0005] To achieve the above purpose, the technical scheme adopted by the utility model is as follows: a brush-type seed meter, including a seed meter housing, a rotating shaft is rotatably connected through the seed meter housing, a sealing turntable is detachably connected to the rotating shaft through a connecting plate, a plurality of uniformly distributed seed storage grooves are formed at the edge of one end surface of the sealing turntable close to the seed meter housing, a seed outlet for discharging seeds is formed on the lower side of the circumferential surface of the seed meter housing, a seed inlet box is fixedly connected to the rear end surface of the seed meter housing, a seed inlet is formed through the rear end surface of the seed meter housing, and the seed meter housing and the seed inlet box are communicated through the seed inlet to realize seed inlet. The brush-type seed meter further includes:
[0006] A clamping brush, which is detachably connected to the upper part of the circumferential inner wall of the seed meter housing, and the clamping brush is rotationally matched with the seed storage groove to limit and clamp seeds;
[0007] A second scraping brush, which is detachably connected to the left part of the rear inner wall of the seed meter housing, and the second scraping brush is located inside the clamping brush;
[0008] A first connecting plate, which is detachably connected to the right part of the rear inner wall of the seed meter housing, and the first connecting plate is located inside the clamping brush.
[0009] Preferably, a limit clamping plate is fixedly connected to the upper part of the inner wall of the seed meter housing through three screws, and the clamping brush is clamped between the inner wall of the seed meter housing and the outside of the limit clamping plate.
[0010] Preferably, the left part of the rear inner wall of the seed metering device housing is fixedly connected with a second connecting plate through two screws, and the second scraping brush is fixedly connected to the front end face of the second connecting plate.
[0011] Preferably, the right part of the rear inner wall of the seed metering device housing is fixedly connected with a first scraping brush through a screw, and the first connecting plate is fixedly connected to the front end face of the first scraping brush.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] In this solution, the clamping brush and the rotating sealing turntable cooperate to realize clamping and moving of seeds for metering. The structure is simple, without too many precision metal parts of traditional seed meters. While maintaining excellent seed metering effect, the production cost is low and replacement and maintenance are convenient.
[0014] In this solution, before the seeds contact the clamping brush, the first connecting plate sweeps across the rear end face of the sealing turntable, so as to seal a single seed in the seed storage groove, thereby avoiding multiple seeds remaining in the seed storage groove or getting stuck between the sealing turntable and the clamping brush. The space in each seed storage groove can only accommodate one seed.
[0015] In this solution, before the seeds are about to contact the clamping brush, the second scraping brush sweeps across the rear end face of the sealing turntable, which can scrape the seeds again, so as to further scrape off the redundant seeds stuck between the sealing turntable and the clamping brush. The second scraping brush can play a limiting role. When the seeds are not blocked by the clamping brush, it can prevent the seeds from being thrown into the right side of the second scraping brush under the action of inertia. At the same time, the second scraping brush separates the seed storage space on the right side of the second scraping brush from the seed outlet space on the left side of the second scraping brush, avoiding the seeds stored in the seed metering device housing from directly entering the seed outlet.

[0020] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.
[0021] As Figures 1 - 3 shown, the brush-type seed metering device includes a seed metering device housing 1. A rotating shaft 11 is rotatably connected through the seed metering device housing 1. A sealing turntable 12 is detachably connected to the rotating shaft 11 through a connecting plate 10. A plurality of uniformly distributed seed storage grooves 13 are formed at the edge of one end face of the sealing turntable 12 close to the seed metering device housing 1. A seed outlet 9 for discharging seeds is formed on the lower side of the circumferential surface of the seed metering device housing 1. A seed inlet box 14 is fixedly connected to the rear end face of the seed metering device housing 1. A seed inlet 6 is formed through the rear end face of the seed metering device housing 1. The seed metering device housing 1 and the seed inlet box 14 are communicated through the seed inlet 6 to achieve seed inlet. It further includes:
[0022] A clamping brush 2, which is detachably connected to the upper part of the circumferential inner wall of the seed metering device housing 1. The clamping brush 2 is rotationally matched with the seed storage groove 13 to limit and clamp seeds;
[0023] A second scraping brush 7, which is detachably connected to the left part of the rear inner wall of the seed metering device housing 1, and the second scraping brush 7 is located inside the clamping brush 2;
[0024] A first connecting plate 4, which is detachably connected to the right part of the rear inner wall of the seed metering device housing 1, and the first connecting plate 4 is located inside the clamping brush 2;
[0025] Three screws are used to fixedly connect a limiting clamping plate 3 to the upper part of the inner wall of the seed metering device housing 1. The clamping brush 2 is clamped between the inner wall of the seed metering device housing 1 and the outside of the limiting clamping plate 3;
[0026] Two screws are used to fixedly connect a second connecting plate 8 to the left part of the rear inner wall of the seed metering device housing 1. The second scraping brush 7 is fixedly connected to the front end face of the second connecting plate 8;
[0027] One screw is used to fixedly connect a first scraping brush 5 to the right part of the rear inner wall of the seed metering device housing 1. The first connecting plate 4 is fixedly connected to the front end face of the first scraping brush 5.
[0028] During operation, when it is necessary to use this device for seeding, connect the rotating shaft 11 to the output end of the driving motor, turn on the driving motor to drive the rotating shaft 11 to rotate, so as to realize the rotating drive of the connecting plate 10 to the sealing turntable 12. Multiple seed storage grooves 13 on the sealing turntable 12 rotate and move along the front end face of the bristles of the clamping brush 2, and the seeds are poured into the seed inlet box 14. The seeds enter the lower part between the seeding device housing 1 and the sealing turntable 12 through the seed inlet 6. The sealing turntable 12 rotates to drive the seeds in the seed storage groove 13 to rotate upward until the seeds are clamped between the clamping brush 2 and the seed storage groove 13. Since the bristles have a certain flexibility and elasticity, during the counterclockwise rotation of the sealing turntable 12 in the direction attached to the specification Figure 1 during the counterclockwise rotation process, the seeds are stuck between the bristles of the clamping brush 2 and the seed storage groove 13 and rotate counterclockwise with the sealing turntable 12 without falling. When the seeds rotate to the seed outlet 9, due to the lack of the blocking and limiting of the clamping brush 2 here, the seeds fall into the seed outlet 9 under the action of gravity, thus completing the seeding;
[0029] This device realizes the clamping and moving seeding through the cooperation of the clamping brush 2 and the rotating sealing turntable 12, and limits and brushes the seeds through the first connecting plate 4 and the second scraping brush 7, which is beneficial to avoid discharging too many seeds each time. The structure is simple, without too many precision metal parts of the traditional seeding device. While maintaining excellent seeding effect, the production cost is low and the replacement and maintenance are convenient;
[0030] Before the seeds contact the clamping brush 2, the first connecting plate 4 sweeps across the rear end face of the sealing turntable 12, so as to seal a single seed in the seed storage groove 13, thereby avoiding multiple seeds remaining in the seed storage groove 13 or being stuck between the sealing turntable 12 and the clamping brush 2. The space in each seed storage groove 13 can only accommodate one seed;
[0031] Before the seeds are about to contact the clamping brush 2, the second scraping brush 7 sweeps across the rear end face of the sealing turntable 12, which can scrape the seeds again, so as to further scrape off the redundant seeds stuck between the sealing turntable 12 and the clamping brush 2. The second scraping brush 7 can play a limiting role to prevent the seeds from being thrown into the right side of the second scraping brush 7 under the action of inertia when the seeds are not blocked by the clamping brush 2. At the same time, the second scraping brush 7 separates the seed storage space on the right side of the second scraping brush 7 and the seed outlet space of the seed outlet 9 on the left side of the second scraping brush 7, avoiding the seeds stored in the seeding device housing 1 from directly entering the seed outlet 9;
[0032] In this solution, the clamping brush 2, the first connecting plate 4 and the second scraping brush 7 are all vulnerable parts. By means of detachable connection, it is convenient to replace the clamping brush 2, the first connecting plate 4 and the second scraping brush 7. The hair length and density of the clamping brush 2 can be selected according to the actual situation, and the clamping brush 2 with a larger density and longer size can be selected, so as to facilitate the seeding of different types of seeds and stably clamp the seeds without falling off.
[0033] Working principle of the utility model:
[0034] When the device is needed for seed metering, connect the output end of the rotating shaft 11 to the driving motor, turn on the driving motor to drive the rotating shaft 11 to rotate, so as to realize the rotating connection plate 10 drives the sealing turntable 12 to rotate. Multiple seed storage grooves 13 on the sealing turntable 12 rotate and move along the front end face of the bristles of the clamping brush 2, pour the seeds into the seed inlet box 14, and the seeds enter the lower part between the seed metering device housing 1 and the sealing turntable 12 through the seed inlet 6. The sealing turntable 12 rotates to drive the seeds in the seed storage groove 13 to rotate upward until the seeds are clamped between the clamping brush 2 and the seed storage groove 13. Since the bristles have a certain flexibility and elasticity, when the sealing turntable 12 rotates counterclockwise in the Figure 1 counterclockwise direction, the seeds are stuck between the bristles of the clamping brush 2 and the seed storage groove 13 and rotate counterclockwise with the sealing turntable 12 without falling. When the seeds rotate to the seed outlet 9, since there is no blocking and limiting of the clamping brush 2 here, the seeds fall into the seed outlet 9 under the action of gravity, thus completing the seed metering.
[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the utility model claimed. The scope of protection claimed by the utility model is defined by the appended claims and their equivalents.
