Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, and in particular to a precision rice seeder. Background Technology

[0002] As an important food crop in my country, rice cultivation technology is gradually developing towards high efficiency and precision. In recent years, with the advancement of agricultural mechanization, rice cultivation methods have gradually shifted from traditional manual sowing to mechanization and intelligentization.

[0003] In the rice sowing process, precise control of the number of seeds is crucial for subsequent growth and yield. Traditional mechanical sowing devices are prone to uneven seed distribution during the seeding process, resulting in inconsistent seedling growth. Too many seeds will lead to waste of resources, while too few will affect the germination rate and yield.

[0004] Some existing rice seeders lack a quantitative delivery device, which makes it impossible to distribute seeds evenly during the sowing process. This can result in some holes having too many seeds while others have too few or no seeds. The sowing amount is difficult to control, which not only increases production costs but may also cause local hypoxia or excessive competition due to seed accumulation, further affecting the germination rate and seedling quality. Utility Model Content

[0005] The main purpose of this invention is to provide a precision rice seeder that can effectively solve the problem that some existing rice seeders lack a quantitative delivery device, resulting in uneven seed distribution during the sowing process. This can lead to situations where some seed holes have too many seeds while others have too few or no seeds, making it difficult to control the sowing amount. This not only increases production costs but may also cause localized oxygen deficiency or excessive competition due to seed accumulation, further affecting germination rate and seedling quality.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A precision rice seeder includes a seeding mechanism. A feeding mechanism is fixedly connected to the upper middle side of the rear end of the seeding mechanism. A drive box is fixedly connected to the left end of the feeding mechanism. A seed delivery tube is fixedly connected to the rear end of the feeding mechanism. A seed box is fixedly connected to the top of the seed delivery tube. A fixing rod is fixedly connected to the outer surface of the seed delivery tube. The lower end of the fixing rod is fixedly connected to the rear side of the top of the drive box.

[0008] Preferably, the seeding mechanism includes a seed metering disc, and side plates are symmetrically fixedly connected to the outer surface of the seed metering disc.

[0009] Preferably, a feeding chute is provided on the upper middle side inside the rear side plate, and a frame is fixedly connected to the opposite sides of the two side plates.

[0010] Preferably, the seed metering tray has seed metering grooves symmetrically arranged on the side circumference, and the inner walls of several seed metering grooves are symmetrically fixedly connected with bearings. The inner surfaces of two bearings located on the same end and the same side are rotatably connected to a rotating shaft.

[0011] Preferably, a cover plate is fixedly connected to the outer surface of several rotating shafts, a limiting frame is slidably connected to the outer surface of several cover plates, and the outer surfaces of several limiting frames are respectively fixedly connected to one side of the inner wall of several seeding troughs.

[0012] Preferably, a mounting box is fixedly connected to the rear end of the seed metering disc near the feed trough, and bearing supports are fixedly connected symmetrically to the inner surface of the mounting box.

[0013] Preferably, the inner surfaces of the two bearing supports are rotatably connected to a rotating shaft, and the outer surface of the rotating shaft is fixedly connected to an installation sleeve.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the implementation of this utility model, by setting up a feeding mechanism, some existing rice seeders lack a quantitative feeding device, which results in the seeds not being fed evenly during the sowing process. Therefore, by driving the rotating shaft two to rotate through the drive box, the seeds can be fed in an orderly manner under the rotation of the fixed plate. By precisely controlling the amount of seeds used, waste can be reduced, which helps to reduce production costs. Moreover, the uniform sowing amount helps the seedlings grow uniformly, which provides convenience for subsequent field management.

[0017] 2. In the implementation of this utility model, by setting a soil covering cutter head, the soil covering cutter head can cover the seeds with soil after sowing on the cover plate, avoiding the trouble of subsequent manual soil covering. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1

[0027] like Figure 1 As shown, a precision rice seeder includes a seeding mechanism 1. A feeding mechanism 2 is fixedly connected to the upper middle side of the rear end of the seeding mechanism 1. A drive box 3 is fixedly connected to the left end of the feeding mechanism 2. A seed delivery tube 4 is fixedly connected to the rear end of the feeding mechanism 2. A seed box 6 is fixedly connected to the top of the seed delivery tube 4. A fixing rod 5 is fixedly connected to the outer surface of the seed delivery tube 4. The lower end of the fixing rod 5 is fixedly connected to the rear side of the top of the drive box 3.

[0028] In this embodiment, rice seeds are poured into the seed box 6 and transported to the feeding mechanism 2 through the seed delivery pipe 4. The drive box 3 drives the rotating shaft 203, causing the rotating shaft 203 to rotate inside the two bearing supports 202. This causes several fixed plates 205 to rotate around the rotating shaft 203 at the feeding trough 103 and the mounting box 201. When the fixed plates 205 rotate, the rice seeds are temporarily stored at the angle between the two fixed plates 205. As the fixed plates 205 rotate, the seeds are gradually transported into the seed metering tray 101. The fixed plates 205 can measure the seeds at intervals to avoid feeding too much at once, resulting in uneven distribution or blockage inside the seed metering tray 101.

[0029] After the seeds enter the sowing mechanism 1, they are sorted by the seed metering plate 101 and finally transported to the seed metering trough 105. As the sowing mechanism 1 rotates, the cover plate 108 touches the bottom and rotates to connect with the rotating shaft 107, so that the seeds can be sown into the soil. The soil covering blade 110 covers the soil as the sowing mechanism 1 rotates. The overall operation is simple and convenient.

[0030] For details, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 In this embodiment, the seeding mechanism 1 includes a seed metering disc 101. Side plates 102 are symmetrically fixedly connected to the outer surface of the seed metering disc 101. A feeding trough 103 is provided on the upper middle side inside the side plate 102 at the rear end. A frame 104 is fixedly connected to the opposite sides of the two side plates 102.

[0031] Further reference Figure 2 , Figure 3 and Figure 5 In this embodiment, seeding grooves 105 are symmetrically arranged on the side circumference inside the seeding tray 101. Bearings 106 are symmetrically fixedly connected to the inner walls of several seeding grooves 105. The inner surfaces of two bearings 106 located on the same end and the same side are rotatably connected to a rotating shaft 107. Cover plates 108 are fixedly connected to the outer surfaces of several rotating shafts 107. Limiting frames 109 are slidably connected to the outer surfaces of several cover plates 108. The outer surfaces of several limiting frames 109 are respectively fixedly connected to one side of the inner wall of several seeding grooves 105.

[0032] By setting up the soil covering cutter head 110, the soil covering cutter head 110 can cover the seeds with soil after sowing on the cover plate 108, avoiding the trouble of subsequent manual soil covering.

[0033] Example 2

[0034] This embodiment adds a feeding mechanism 2 to the sowing mechanism 1 and the seed box 6 to uniformly deliver seeds. By setting the feeding mechanism 2, the seeds can be fed in an orderly manner under the rotation of the fixed plate 205, so as to achieve the effect of precise control of the amount of seeds used.

[0035] For details, please refer to Figure 2 , Figure 4 , Figure 5 and Figure 6 In this embodiment, a mounting box 201 is fixedly connected to the rear end of the seed metering disc 101 near the feed trough 103. Bearing supports 202 are fixedly connected symmetrically to the inner surface of the mounting box 201. Rotating shaft 203 is rotatably connected to the inner surfaces of the two bearing supports 202. Mounting sleeve 204 is fixedly connected to the outer surface of the rotating shaft 203.

[0036] Further reference Figure 4 , Figure 5 and Figure 6 In this embodiment, a fixing plate 205 is symmetrically fixed to the outer surface of the mounting sleeve 204. The left end of the rotating shaft 203 passes through the left side of the inner surface of the mounting box 201 and the right side of the inner surface of the drive box 3. The left end of the rotating shaft 203 is rotatably connected to the drive box 3. The lower side of the front end of the seed delivery tube 4 is fixedly connected to the rear end of the mounting box 201.

[0037] By driving the rotating shaft 203 to rotate through the drive box 3, the seeds can be fed in an orderly manner under the rotation of the fixed plate 205. By precisely controlling the amount of seeds used, waste can be reduced, which helps to lower production costs. The uniform sowing amount also helps the seedlings grow uniformly, which facilitates subsequent field management.

[0038] The drive box 3 in this solution includes a fixed box, and the drive motor and motor controller are installed inside the fixed box. The motor controller here can be a controller that can be matched with the drive motor in the prior art, which can control the switching and rotation speed of the drive motor. Since it is a very mature product in the prior art, it will not be described in detail in this application.

[0039] It should be noted that the specific installation method of the drive box, the circuit connection method, and the control method used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
