Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery cleaning technology, and in particular to a cleaning device for preventing blockage of the seed metering device of a corn planter. Background Technology

[0002] As a key piece of planting equipment in modern agricultural production, the corn planter's core component, the seed metering device, directly affects the precision and efficiency of the planting operation. The seed metering device typically consists of a seed unit and a gearbox. The rotation of the seed metering wheel quantitatively discharges seeds from the seed delivery tube and sows them into the soil. In actual operation, due to the complex field environment, impurities such as weeds, straw fragments, soil, and broken corn seeds often mix into the seed metering system. These impurities easily adhere to or become stuck on the surface or in the gaps of the seed metering wheel. Over time, this accumulation can easily cause blockages in the seed metering channel, leading to problems such as missed sowing and double sowing, seriously affecting the sowing quality and the uniformity of crop emergence.

[0003] Currently, the common method for cleaning seed metering wheels that become clogged is manual: operators must remove the seed metering wheel from the seed meterer, immerse it in a basin of water, and manually scrub its surface impurities using tools such as steel wool. This method is not only labor-intensive and inefficient, but also poses a safety hazard as the sharp parts of the seed metering wheel can easily cut the operator's hands during the cleaning process. In addition, if the water stains remaining on the surface of the seed metering wheel after cleaning are not completely removed, it can easily lead to rust or corrosion of the metal parts, affecting its service life and seed metering performance. Therefore, it is necessary to design an anti-clogging cleaning device for corn planter seed meterers to address the shortcomings of existing technologies. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a corn planter seed metering device to prevent blockage and clean the device.

[0005] The technical solution of this utility model is as follows: a corn planter seed metering device for preventing blockage and cleaning, comprising a base, a basin, and a cover. A bracket is fixedly installed on the base, and a basin with an upward opening is fixedly connected to the top of the bracket. A cover is rotatably installed on the rear side of the basin, and the basin and cover can rotate to align and close. A locking block for the cover is provided on the front side of the basin. A placement plate is rotatably installed at the center of the bottom of the basin. A motor is fixedly installed on the base, and the output shaft of the motor is connected to the rotation shaft of the placement plate. The placement plate has at least three positioning shafts spaced circumferentially. The positioning shafts are used to position and place the seed metering wheel to be cleaned. A cleaning brush is installed inside the cover via a mounting shaft. The bristles of the cleaning brush can contact and brush the seed metering wheel on the positioning shaft. A spray pipe is provided on one side of the cover. The spray pipe is used to connect to an external water pump. The nozzle of the spray pipe is located inside the basin and faces the placement plate. A drain pipe is connected to the bottom of the basin.

[0006] As a preferred embodiment of this utility model, the top of the positioning shaft is provided with an outwardly protruding rubber ring, which is used to stabilize and limit the seed metering wheel on the positioning shaft, thereby improving the stability of the seed metering wheel on the positioning shaft.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0019] A corn planter seed metering device for preventing blockage and cleaning, such as Figures 1-4 As shown, the device includes a base 1, a basin 2, and a cover 3. A bracket 21 is fixedly mounted on the base 1, and the basin 2 with its opening facing upward is fixedly connected to the top of the bracket 21. The cover 3 is rotatably mounted on the rear side of the basin 2. The basin 2 and the cover 3 can rotate to align and close. A locking block 22 is provided on the front side of the basin 2 to lock the cover 3. A placement plate 5 is rotatably mounted at the center of the bottom of the basin 2. A motor 4 is fixedly mounted on the base 1. The output shaft of the motor 4 is connected to the rotation shaft of the placement plate 5. Three positioning shafts 51 are arranged circumferentially on the plate body of the placement plate 5. The positioning shafts 51 are used to position and place the seeding wheels 6 to be cleaned. A cleaning brush 7 is installed on the inner side of the cover 3 through a mounting shaft 71. The bristles of the cleaning brush 7 can contact and brush the seeding wheels 6 on the positioning shafts 51. A spray pipe 10 is provided on one side of the cover 3. The spray pipe 10 is used to connect to an external water pump. The nozzle of the spray pipe 10 is located inside the basin 2 and faces the placement plate 5. A drain pipe 8 is connected to the bottom of the basin 2.

[0020] like Figure 1 and Figure 3 As shown, a rubber ring 52 protruding outward is provided on the top of the positioning shaft 51. The rubber ring 52 is used to stabilize and limit the seed metering wheel 6 on the positioning shaft 51, thereby improving the stability of the seed metering wheel 6 on the positioning shaft 51.

[0021] like Figure 2 As shown, a solenoid valve 9 is installed on the drain pipe 8, which is used to control the opening and closing of the drain pipe 8; a flow limiting valve 11 is installed on the nozzle 10, which is used to regulate the flow rate of the nozzle 10.

[0022] like Figure 2 As shown, the cleaning brush 7 is detachably installed inside the cover 3, and the outer wall of the cover 3 is provided with a locking element for locking the mounting shaft 71.

[0023] like Figure 2 and Figure 4As shown, the locking mechanism includes a guide block 12, a rod 13, and a spring 14. The guide block 12 is fixedly mounted on the outer wall of the cover 3. The rod 13 is slidably connected to the guide block 12. The end of the mounting shaft 71 of the cleaning brush 7 has a hole adapted to the rod 13. The spring 14 is provided between the guide block 12 and the rod 13. The rod 13 is pushed and pulled against the elastic force of the spring 14. After the rod 13 disengages from the hole of the mounting shaft 71, the cleaning brush 7 and the mounting shaft 71 can be removed from the cover 3, which facilitates the maintenance and replacement of the cleaning brush 7.

[0024] In use, the seed metering wheel 6 to be cleaned is placed on the positioning shaft 51 of the placement tray 5. At this time, the rubber ring 52 can effectively prevent the seed metering wheel 6 from falling off the positioning shaft 51. Then, the cover 3 is rotated to cover the basin 2 and locked with the locking block 22. In this state, the bristles of the cleaning brush 7 on the inside of the cover 3 will be closely attached to the upward-facing side of the seed metering wheel 6. When the cleaning process begins, the motor 4 and the external water pump connected to the spray pipe 10 are turned on simultaneously. The motor 4 drives the placement tray 5 to rotate at a constant speed, and the placement tray 5 drives the seed metering wheel 6 on it to rotate. At the same time, the clean water supplied by the water pump is continuously sprayed onto the surface of the rotating seed metering wheel 6 through the spray pipe 10. The water flow can wash away the dirt and impurities on the loose seed metering wheel 6. The cleaning brush 7, which is close to the wheel surface, will clean the seed metering wheel 6 during its rotation. In the process, the holes and grooves on the surface of the seed roller 6 are thoroughly scrubbed to remove stubborn blockages. The water and the scrubbed dirt fall into the bottom of the basin 2. After the top side of the seed roller 6 is cleaned, the cover 3 is opened and the seed roller 6 is flipped over one by one. The above closing and starting steps are repeated to thoroughly clean the other side with the same effect. After both sides of the seed roller 6 are clean, the water pump is turned off and the solenoid valve 9 on the drain pipe 8 is opened. The sewage accumulated in the basin 2 is then discharged. Finally, the motor 4 is started again, causing the placement tray 5 to drive the clean seed roller 6 to rotate at high speed. Centrifugal force completely removes the residual water on the surface and in the gaps of the seed roller 6, thereby achieving rapid drying. At this point, the entire cleaning process is completed, and the seed roller 6 is restored to a clean and ready-to-use state.
