Description

Technical Field

[0001] This utility model belongs to the technical field of sowing adjustment, and in particular relates to an automatic sowing depth adjustment device. Background Technology

[0002] Sowing depth refers to the distance a seed travels from the soil surface to the point where it stops falling. It has a significant impact on seed germination rate, seedling quality, and the growth and yield of subsequent crops. When the soil is moist, the sowing depth can be slightly shallower, as moist soil is conducive to seed germination and growth. When the soil is dry, the sowing depth should be appropriately increased to ensure that the seeds can absorb enough water to germinate.

[0003] Traditional seeders require adjusting the position of the seeding digging device before sowing to adjust the sowing depth according to actual sowing needs. However, in actual use, different plants have different sowing spacings, and automatic seeding cannot be controlled, necessitating additional equipment to sow seeds inside the seeding digging furrow. To address these issues, we provide an automatic sowing depth adjustment device. Utility Model Content

[0004] The purpose of this invention is to provide an automatic sowing depth adjustment device, which solves the problems in the background art by the specific structural design of the support adjustment component and the sowing material feeding component.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an automatic sowing depth adjustment device, including a support adjustment assembly. The support adjustment assembly includes a sowing support platform that can move up and down. An adjustment slide is provided on the surface of the sowing support platform. A plurality of transmission support frames are slidably arranged inside the adjustment slide. One side of each transmission support frame is fixedly connected to an opening and closing drive wheel via an extension column. Two support plates are symmetrically fixedly connected to the lower surface of the sowing support platform. A drive shaft is rotatably connected between the two support plates. Two limiting strips are symmetrically fixedly connected to the periphery of the drive shaft. The transmission support frame slides in cooperation with the drive shaft and the limiting strips. A seeding and feeding assembly is provided, each corresponding to a transmission support frame. The seeding and feeding assembly includes a hollow material storage frame that slides with a drive shaft and a limiting strip. Several discharge ports are opened on the periphery of the hollow material storage frame. Discharge frames corresponding to the discharge ports are fixedly connected to the periphery of the hollow material storage frame. A rotating shaft is rotatably connected between the two inner side walls of the discharge frames. An opening and closing control plate is fixedly connected to the periphery of the rotating shaft. A torsion spring is fixedly connected between the opening and closing control plate and the two inner side walls of the discharge frames. The torsion spring is sleeved outside the rotating shaft. An opening and closing drive linkage is rotatably provided on one side of the discharge frames. The opening and closing drive linkage is fixedly connected to the rotating shaft and is adapted to the opening and closing drive wheel.

[0006] The present invention is further configured such that the support adjustment assembly includes symmetrically fixed guide rails, and a drive screw is rotatably connected between the guide rails and the two inner side walls. An extension transmission block is fixed on the two sides of the sowing support platform, and the extension transmission block is threadedly engaged with the corresponding drive screw. The other side of the transmission support frame is fixedly connected to a sowing plow head corresponding to the sowing and feeding assembly through an L-shaped support column.

[0007] The present invention is further configured such that: a guide groove is provided on the upper surface of the sowing support platform; an adjustment transmission plate is slidably provided on the upper surface of the sowing support platform; a transmission block that slidably engages with the guide groove is fixedly connected to the lower surface of the adjustment transmission plate; a vertical groove is provided on the upper surface of the adjustment transmission plate; two inclined grooves are symmetrically provided on the upper surface of the adjustment transmission plate; an adjustment transmission column is slidably provided inside both the vertical groove and the inclined groove; and an adjustment transmission plate is fixedly connected to the upper end of the adjustment transmission column.

Detailed Implementation

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] For a specific implementation example, please refer to Implementation Example 1. Figure 1-5 This utility model is an automatic sowing depth adjustment device, including a support adjustment component 1. Further, the support adjustment component 1 includes a sowing support platform 101 that can move up and down. An adjustment slide 102 is provided on the surface of the sowing support platform 101. Several transmission support frames 103 are slidably arranged inside the adjustment slide 102. One side of the transmission support frame 103 is fixedly connected to an opening and closing drive wheel 104 through an extension column. Two support plates are symmetrically fixedly connected to the lower surface of the sowing support platform 101. A drive shaft 105 is rotatably connected between the two support plates. A drive motor is installed on one side of one of the support plates. The output shaft of the drive motor is fixedly connected to the drive shaft 105. Two limiting strips 106 are symmetrically fixedly connected to the periphery of the drive shaft 105. The transmission support frame 103 slides in cooperation with the drive shaft 105 and the limiting strips 106.

[0021] Furthermore, a seeding and feeding assembly 2 corresponding to the transmission support frame 103 is slidably arranged on the circumferential side of the drive shaft 105. The seeding and feeding assembly 2 includes a hollow material storage frame 201 that slides between the drive shaft 105 and the limiting strip 106. Several discharge ports are opened on the circumferential side of the hollow material storage frame 201. A discharge frame 202 corresponding to each discharge port is fixedly connected to the circumferential side of the hollow material storage frame 201. A rotating shaft is rotatably connected between the discharge frame 202 and its two inner side walls. An opening and closing control plate 203 is fixedly connected to the circumferential side of the rotating shaft. A torsion spring is fixedly connected between the opening and closing control plate 203 and the two inner side walls of the discharge frame 202. The torsion spring is sleeved outside the rotating shaft. An opening and closing drive linkage 204 is rotatably arranged on one side of the discharge frame 202. The opening and closing drive linkage 204 is fixedly connected to the rotating shaft and is adapted to the opening and closing drive wheel 104.

[0022] The operation process of this embodiment is as follows: By adjusting the up and down movement of the sowing support platform 101, the sowing depth is adjusted. During sowing, the entire device is controlled to move radially to sow and open furrows. During the movement, the drive motor is started to drive the drive shaft 105 to rotate. Under the action of the limit bar 106, the hollow material storage frame 201 is driven to rotate synchronously. During the rotation of the hollow material storage frame 201, the opening and closing drive linkage 204 rotates synchronously with the hollow material storage frame 201. When the corresponding opening and closing drive linkage 204 contacts the opening and closing drive wheel 104, as the hollow material storage frame 201 continues to move, the opening and closing drive linkage 204 is obstructed by the opening and closing drive wheel 104 and subjected to external force. The tilting of the shaft causes the opening and closing control plate 203 to rotate synchronously and gradually move away from the discharge frame 202. The discharge frame 202 is opened, and the seeds inside the hollow storage frame 201 fall for sowing. As the hollow storage frame 201 continues to rotate, when the corresponding opening and closing drive linkage 204 disengages from the disengagement drive wheel 104, the opening and closing control plate 203 rotates in the opposite direction under the action of the torsion spring until it comes into contact with the discharge frame 202. The discharge frame 202 stops dropping material, thus completing one sowing operation. As the hollow storage frame 201 continues to rotate, each time the opening and closing drive linkage 204 contacts and disengages from the disengagement drive wheel 104, one sowing operation is completed.

[0023] For a specific embodiment two, please refer to Figure 1-5Based on the specific embodiment 1, specifically, the support adjustment component 1 also includes symmetrically fixed guide rails 107. The guide rails 107 are fixedly connected to the external sowing mobile device. The sowing mobile device can drive the entire device to move. The guide rails 107 are rotatably connected to the two inner side walls with drive screws 108. A drive source is fixedly installed on one side of the guide rails 107. The output end of the drive source is fixedly connected to the drive screws 108. The sowing support platform 101 has extended transmission blocks fixed on the two sides. The extended transmission blocks are threadedly engaged with the corresponding drive screws 108. The other side of the transmission support frame 103 is fixedly connected to a sowing plow head 109 corresponding to the sowing feeding component 2 through an L-shaped support column.

[0024] Furthermore, a guide groove is provided on the upper surface of the sowing support platform 101, and an adjustment transmission plate 110 is slidably arranged on the upper surface of the sowing support platform 101. An extension transmission plate is fixedly connected to the upper surface of the adjustment transmission plate 110. An electric push rod is fixedly installed on the upper surface of the sowing support platform 101 through a vertical plate. The output end of the electric push rod is fixedly connected to the extension transmission plate. A transmission block that slides with the guide groove is fixedly connected to the lower surface of the adjustment transmission plate 110. A vertical groove 111 is provided on the upper surface of the adjustment transmission plate 110, and two inclined grooves 112 are symmetrically provided on the upper surface of the adjustment transmission plate 110. The vertical groove 111 is located in the middle position, and the two inclined grooves 112 are located on both sides of the vertical groove 111. An adjustment transmission column is slidably arranged inside the vertical groove 111 and the inclined groove 112. An adjustment transmission plate 113 is fixedly connected to the upper end of the adjustment transmission column.

[0025] Furthermore, a feeding slide is provided on the periphery of the hollow storage frame 201, and an arc-shaped sealing strip 205 is slidably arranged inside the feeding slide. A feeding hopper 206 is slidably arranged inside the feeding slide. Seeds enter the hollow storage frame 201 through the feeding hopper 206. The two opposite sides of the feeding hopper 206 are in contact with the two ends of the arc-shaped sealing strip 205. The hollow storage frame 201 is slidably engaged with the limiting strip 106. The feeding hopper 206 is fixedly connected to the corresponding transmission support frame 103 and the corresponding adjusting transmission plate 113. The hollow storage frame 201 in the middle position is fixedly connected to the adjusting transmission plate 113 opposite to the vertical slide groove 111.

[0026] The operation process in this embodiment is as follows: Before sowing, adjust the spacing between the sowing plow heads 109 according to the needs of seed sowing. The specific operation process is as follows:

[0027] The electric actuator drives the regulating transmission plate 110 to move horizontally. When the regulating transmission plate 110 moves closer to the regulating slide rail 102, the regulating transmission column slides with the corresponding vertical slide rail 111 and inclined slide rail 112, keeping the position of the regulating transmission plate 113 (the regulating transmission plate 113 opposite to the vertical slide rail 111) fixed. The regulating transmission plates 113 on both sides (the regulating transmission plates 113 opposite to the inclined slide rail 112) gradually move towards the middle position along the direction of the inclined slide rail 112. This causes the seeding and feeding assembly 2 and the transmission support frame 103 to move synchronously, reducing the interval between the seeding and feeding assemblies 2 and the distance between them. When the electric push rod drives the regulating transmission plate 110 to move away from the regulating slide 102, the regulating transmission column and the corresponding vertical slide 111 and inclined slide 112 slide together, causing the regulating transmission plates 113 on both sides to gradually disperse to both sides, and the seeding and feeding assembly 2 and the transmission support frame 103 to move synchronously, increasing the interval between the seeding and feeding assemblies 2.

[0028] Adjusting the sowing depth according to the needs of seed growth, controlling the rotation of the drive screw 108, and under the threaded cooperation between the drive screw 108 and the corresponding extension transmission block, the extension transmission block slides along the corresponding guide rail 107, thereby driving the entire device to move up and down synchronously through the sowing support platform 101. The depth of sowing furrows is adjusted by the up and down movement of the sowing plow head 109 (the sowing depth increases when the sowing plow head 109 moves downward, and the sowing depth decreases when the sowing plow head 109 moves upward).

[0029] During sowing, the external sowing device is moved, causing the sowing plow 109 to move synchronously. The sowing plow 109 is used to sow furrows at the corresponding depth. Simultaneously, during this movement, the drive motor drives the drive shaft 105 to rotate. Under the action of the limit strip 106, the hollow material storage frame 201 rotates synchronously. Since the hollow material storage frame 201 is fixedly connected to the corresponding transmission support frame 103, and the transmission support frame 103 is slidably positioned inside the adjusting slide 102, the hollow material storage frame 201 slides along the feeding slide, simultaneously pushing the arc-shaped sealing strip 205 to slide continuously along the feeding slide. During the rotation of the hollow material storage frame 201, the opening and closing drive linkage 204 rotates synchronously with the hollow material storage frame 201. When the corresponding opening and closing drive linkage 204 and the opening and closing drive wheel 10... When the four phases come into contact, as the hollow storage frame 201 continues to move, the opening and closing drive linkage 204 is obstructed by the opening and closing drive wheel 104 and tilts under the action of external force, thereby driving the rotating shaft to rotate. This causes the opening and closing control plate 203 to rotate synchronously and gradually move away from the discharge frame 202, opening the discharge frame 202. The seeds inside the hollow storage frame 201 fall for sowing. As the hollow storage frame 201 continues to rotate, when the corresponding opening and closing drive linkage 204 disengages from the opening and closing drive wheel 104, the opening and closing control plate 203 rotates in the opposite direction under the action of the torsion spring until it comes into contact with the discharge frame 202. The discharge frame 202 stops dropping material, thus completing one sowing operation. As the hollow storage frame 201 continues to rotate, each time the opening and closing drive linkage 204 contacts and disengages from the opening and closing drive wheel 104, the sowing operation is repeated.
