Description

Technical Field

[0001] This utility model belongs to the field of corn planting technology, and in particular to a corn planting machine with adjustable spacing. Background Technology

[0002] Corn planting requires the use of planting machines. Existing planting machines often have adjustable planting spacing to meet the needs of corn planting, but they require adjustment of multiple corn feeding ports, which cannot be adjusted synchronously. The adjustment method is complicated, reducing the ease of use of the planting machine.

[0003] A search of related technologies revealed a Chinese patent document (authorization announcement number CN222736621U) for an adjustable-spacing corn planter. This invention includes a frame supporting a hopper. A feeding mechanism is installed at the bottom of the hopper, and a lifting mechanism is installed on one side of the hopper. A first fixed plate and a second fixed plate are symmetrically connected to the bottom of the lifting mechanism. The first and second fixed plates jointly support an adjusting mechanism, which is equipped with multiple seeding tubes. Each seeding tube is connected to the bottom of the hopper, and multiple discharge pipes are evenly distributed at the bottom of the hopper. Each discharge pipe is connected to its corresponding seeding tube by a corrugated pipe. This invention not only adjusts the spacing between corn seeds but also the seeding depth, thereby improving the practicality of the planter for corn planting. However, the aforementioned patent does not consider the inability to simultaneously adjust multiple corn feeding ports, resulting in a complex adjustment method and reduced ease of use for the planter.

[0018] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0019] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0020] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0021] Please see Figures 1 to 5 An adjustable-spacing corn planting machine, in this embodiment, includes: The corn frame 1 is in the shape of an inverted U. The top and side surfaces of the corn frame 1 are respectively provided with a feed bin 2 and a sowing component 3. The sowing component 3 includes a mounting frame 4 and a sowing tube 5 for planting corn. The bottom surface of the mounting frame 4 is slidably connected to the sowing tube 5. The mounting frame 4 is in the shape of an L.

[0022] The positioning component 6 is used to adjust the corn planting spacing. The positioning component 6 includes a positioning frame 7 and a movable frame 8. The positioning frame 7 is U-shaped and the movable frame 8 is square-shaped. The positioning frame 7 has a positioning sliding sleeve 9 sleeved on its side and the movable frame 8 has a movable sliding sleeve 11 sleeved on its side. The movable sliding sleeve 11 is sleeved on the side wall of the movable frame 8. The side of the movable sliding sleeve 11 is rotatably connected to two movable plates 10 by a pin. The end face of the movable plate 10 is slidably connected to the positioning sliding sleeve 9 by a pin. The bottom surface of the positioning sliding sleeve 9 is welded to the mounting frame 4.

[0023] Several positioning sleeves 9 and several movable sleeves 11 are arranged alternately. Each positioning sleeve 9 has two movable plates 10 rotatably connected to two movable sleeves 11. The leftmost and rightmost positioning sleeves 9 are rotatably connected to a movable plate 10 through a pin. The top surface of the middle positioning sleeve 9 is threaded with a clamping bolt for pressing against the positioning frame 7, thereby fixing the position of the middle positioning sleeve 9 and providing conditions for synchronous adjustment of the spacing of several seeding tubes 5. Movable frames 12 are welded to both ends of the movable frame 8. The movable frames 12 are C-shaped. There is sufficient space between the top surfaces of the two movable frames 12 and the inner top surface of the corn machine frame 1. The inner wall of the movable frames 12 is slidably connected with a slide rail 13. Thanks to the design of the positioning component 6, the synchronous spacing of several seeding tubes 5 can be adjusted, improving the ease of use of the planter.

[0024] The top surface of the positioning frame 7 is connected to the corn machine frame 1 by bolts. The opposite sides of the two slide rails 13 are welded to the corn machine frame 1. The outer wall of the movable frame 8 is connected to the moving end of the electric push rod 14 by bolts. The fixed end of the electric push rod 14 is connected to the L-shaped mounting plate 15 by bolts. The top surface of the mounting plate 15 is connected to the corn machine frame 1 by bolts. The top surface of the seeding pipe 5 is connected to the conveying pipe 16. The conveying pipe 16 is a food-grade polyurethane hose. When the seeding pipe 5 is moved to the top, the top surface of the seeding pipe 5 is still much lower than the height of the feed bin 2, so that the corn kernels in the conveying pipe 16 can be easily fed into the seeding pipe 5, providing conditions for corn planting. The outer periphery of several conveying pipes 16 is connected to the feed bin 2. The side of the seeding pipe 5 is welded with an L-shaped connecting plate 20. The top surface of several connecting plates 20 is welded with a C-shaped limiting plate 19. The two outer walls of the limiting plate 19 are slidably connected to an inverted U-shaped limiting frame 17.

[0025] The bottom surface of the limiting frame 17 is welded to the corn machine frame 1. An electric push rod 21 is installed on the top surface of the limiting frame 17. The fixed end of the electric push rod 21 is connected to the limiting frame 17 by bolts, and the moving end of the electric push rod 21 passes through the top wall of the limiting frame 17. The moving end of the electric push rod 21 is connected to the limiting plate 19 by bolts. Sliding sliders 18 are embedded in both sides of the limiting frame 17. The adjacent sides of the two sliders 18 are welded to the limiting plate 19. Thanks to the design of the sowing component 3, the vertical position of several sowing tubes 5 can be adjusted to meet the planting needs of corn. The electric push rod 21 provides power so that the two sliders 18 move along the path of the limiting frame 17. With the connection of the limiting plate 19 and several connecting plates 20, the sowing tubes 5 move along the path of the mounting frame 4, which enhances the vertical movement stability of the sowing tubes 5.

[0026] The side walls of the positioning frame 7 and the movable frame 8 need to be cleaned regularly. Use a high-pressure air gun to blow away surface impurities, and then wipe them clean with a cotton cloth soaked in alcohol. Afterwards, apply high-temperature and wear-resistant grease (lithium-based grease No. 3) to the side walls of the positioning frame 7 and the movable frame 8, as well as the inner walls of the positioning sleeve 9 and the movable sleeve 11. The thickness of the grease should be 0.5-1mm to ensure that the sliding surfaces are fully lubricated. Check the wear of the pin connecting the movable plate 10 to the positioning sleeve 9 and the movable sleeve 11. If the wear of the pin diameter exceeds 0.2mm, the pin needs to be replaced in time. At the same time, apply grease between the pin and the pin hole to ensure that the pin rotates flexibly. Check the fit clearance between the slider 18 and the slide groove of the limit frame 17. If the clearance exceeds 0.15mm, the slider 18 needs to be replaced. At the same time, check the wear of the surface of the slider 18. If the wear is uneven, the surface of the slider 18 needs to be polished to ensure that the surface flatness error of the slider 18 does not exceed 0.05mm.

[0027] The original food-grade polyurethane hose was replaced with a polyurethane hose with a spiral steel wire skeleton. The steel wire skeleton is made of 304 stainless steel with a wire diameter of 1mm and a spiral spacing of 20mm. This enhances the bending resistance of the conveying tube 16 and prevents it from bending and clogging when the seeding tube 5 moves. A transparent observation window and cleaning port are added to the middle of each conveying tube 16. The observation window is made of polycarbonate and is 5mm thick, allowing operators to easily observe the seed delivery inside the conveying tube 16. The cleaning port uses a threaded sealing cap. When the conveying tube 16 becomes clogged, the sealing cap can be opened, and a special cleaning rod can be used to unclog the conveying tube 16. The cleaning rod is made of plastic to avoid damaging the inner wall of the conveying tube 16.

[0028] Electric actuator 14 and electric actuator 21 are conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. In order to facilitate the inspection, maintenance, and parts replacement of the device, the parts inside a single device are usually from the same manufacturer and of the same model, function, and batch. Therefore, even if there is a certain difference between two or more electrical control devices, the synchronous movement of the electrical control devices can still be maintained under the action of the controller. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail in this utility model. All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology.

[0029] Working principle When using this adjustable spacing corn planter, the electric push rod 14 is activated, causing the moving frame 8 to move the two movable frames 12 along the path of the two slide rails 13. Several movable sliding sleeves 11 move along the path of the moving frame 8, and several positioning sliding sleeves 9 move along the path of the positioning frame 7. The central positioning sliding sleeve 9 is connected and fixed to the positioning frame 7 by bolts. With the connection of several movable plates 10, the sowing spacing of several sowing tubes 5 can be adjusted synchronously. Start the electric push rod 21, so that the two sliders 18 move along the path of the limiting frame 17. Under the connection of the limiting plate 19 and several connecting plates 20, several seeding tubes 5 move along the path of the mounting frame 4, so that the seeding tubes 5 move to the designated position for corn sowing.
