Description

Technical Field

[0001] The utility model relates to a sowing mechanism, in particular to a sowing mechanism for a crop planting robot. Background Technique

[0002] Traditional crop planting mainly relies on manual labor. The manual planting method has the problem of high labor costs. In the process of manual planting, labor is an indispensable factor. However, with the annual increase in labor costs, the labor costs in the planting industry have also increased accordingly. This has led many growers to hesitate when considering whether to expand the planting scale or adopt more advanced planting technologies due to the high labor costs. Manual planting also has the problem of uneven technical levels. Due to the uneven technical levels of growers, problems such as improper techniques or insufficient application of techniques often occur in manual planting. This not only affects the planting efficiency but may also have an adverse impact on crop growth, thereby reducing the yield and quality. In short, manual planting highly depends on labor and is easily affected by factors such as weather and soil, resulting in unstable yields.

[0003] The problems brought about by manual planting urgently require further improvement in the intelligence of planting technologies. The intelligent planter combines traditional planting methods with intelligent technologies, greatly improving the planting efficiency and stability. The sowing mechanism of the planter is the key, which directly affects the planting efficiency and the stability of the yield. However, traditional machinery cannot achieve fixed-distance and fixed-quantity sowing, thus affecting the uniform distribution of seeds in the field, the emergence rate in the field, and the uniformity of seedling growth, as well as subsequent field management and mechanical harvesting. Therefore, this application provides a sowing mechanism for a crop planting robot. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sowing mechanism for a crop planting robot to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A sowing mechanism for a crop planting robot, including a feeding box, a blanking transmission box and a blanking tube that are interconnected. A driving motor is fixedly installed on the outside of the blanking transmission box. The end of the output shaft of the driving motor penetrates through the housing wall of the blanking transmission box and a guiding plate fixed on the inner side wall of the blanking transmission box and extends inward. A sliding ring is slidably installed on the guiding plate. Gear teeth are provided on the straight rails on both opposite sides of the sliding ring, and the gear teeth are meshed with incomplete gear teeth. The incomplete gear is arranged inside the sliding ring and is connected to the end of the output shaft of the driving motor;

[0006] At the top and bottom of the sliding ring, a first push rod and a second push rod are respectively fixed. The end part of the first push rod extends to the feeding port at the bottom of the feeding box, and a conical plug is arranged at this end part for blocking the feeding port. A soil-breaking cone is arranged at the end part of the second push rod.

[0007] A slider is arranged on the first push rod, and the slider is slidably installed on a guide rail arranged on the inner side wall of the blanking transmission box.

[0008] The second push rod passes through a guide tube, and the guide tube is arranged in the blanking cylinder.

[0009] A guide block is arranged on the second push rod, and the guide block is arranged in the guide tube.

[0010] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0011] Through the cooperation among the drive motor, the incomplete gear, the sliding ring and the guide plate, the present utility model drives the periodic operation of the first push rod and the second push rod to respectively drive the conical plug and the soil-breaking cone, thereby periodically opening the feeding port at the bottom of the feeding box and simultaneously breaking the soil periodically, enabling the crop seeds to fall into the soil at intervals, realizing quantitative and fixed-distance sowing, thus facilitating the uniform distribution of seeds in the field, as well as the field emergence rate and the uniformity of seedling growth, improving the planting efficiency and the stability of yield, and facilitating subsequent field management and mechanical harvesting.

[0012] 2. The present utility model is provided with a guide tube. By means of the guide block, the stable up-and-down movement of the second push rod in the guide tube is ensured. At the same time, after the soil-breaking cone is inserted into the soil and pulled out, the soil on the soil-breaking cone enters the guide tube, thereby avoiding the blockage of the blanking tube and preventing the situation of unable to sow.

Specific implementation manner

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1: Please refer to Figures 1-4 , a seeding mechanism for a crop planting robot, including a feeding box 1, a blanking transmission box 2 and a blanking tube 3 that are interconnected. A driving motor 4 is fixedly installed outside the blanking transmission box 1. The end of the output shaft of the driving motor 4 penetrates through the housing wall of the blanking transmission box 2 and the guide plate 5 fixed on the inner side wall of the blanking transmission box 2 and extends inward. A sliding ring 6 is slidably installed on the guide plate 5. Gear teeth 7 are provided on the straight rails on opposite sides of the sliding ring 6, and the gear teeth 7 mesh with the teeth of the incomplete gear 8. The incomplete gear 8 is arranged inside the sliding ring 6 and is connected to the end of the output shaft of the driving motor 4. The top and bottom of the sliding ring 6 are respectively fixed with a first push rod 9 and a second push rod 10. The end of the first push rod 9 extends to the feeding port at the bottom of the feeding box 1, and a conical plug 11 is provided at the end for blocking the feeding port. A soil-breaking cone 16 is provided at the end of the second push rod 10.

[0021] Specific implementation process of Embodiment 1: First, pour crop seeds into the feeding box 1, start the driving motor 4, and continuously sow as the seeding vehicle moves. Specifically, the driving motor 4 drives the incomplete gear 8 to rotate. The teeth of the incomplete gear 8 intermittently mesh with the gear teeth 7 on the straight rails on opposite sides of the sliding ring 6, causing the sliding ring 6 to move downward along the guide plate 5. Then, the first push rod 9 drives the conical plug 11 to move downward away from the feeding port at the bottom of the feeding box 1. At the same time, the second push rod 10 pushes the soil-breaking cone 16 to break the soil. During this process, the crop seeds fall from the feeding port into the blanking transmission box 2 and fall from the blanking tube 3 to the soil-breaking place to achieve sowing. When the driving motor 4 continues to drive the incomplete gear 8 to rotate, through the cooperation of the incomplete gear 8 and the sliding ring 6, the sliding ring 6 moves upward along the guide plate 5, so that the first push rod 9 drives the conical plug 11 to move upward to block the feeding port, and at the same time the second push rod 10 drives the soil-breaking cone 16 to retract. During this process, the crop seeds do not feed, so quantitative and fixed-distance sowing is achieved throughout the process.

[0022] A slider 13 is provided on the first push rod 9. The slider 13 is slidably mounted on a guide rail 14 provided on the inner side wall of the blanking transmission box 2. When the first push rod 9 moves up and down, the slider 13 can slide on the guide rail 14, ensuring the stability of the movement of the first push rod 9.

[0023] Embodiment 2: Please refer to Figures 1-2 , on the basis of the technical solution of Embodiment 1, the second push rod 10 passes through the guide tube 12. The guide tube 12 is arranged in the blanking cylinder 3. After the soil-breaking cone 16 is inserted into the soil and pulled out, the soil on the soil-breaking cone 16 enters the guide tube 12, thus avoiding the situation that the outlet of the blanking tube 3 is blocked and sowing cannot be carried out. A guide block 15 is provided on the second push rod 10. The guide block 15 is arranged in the guide tube 12. When the second push rod 10 moves up and down, the guide block 15 can slide in the guide tube 12, ensuring the stability of the movement of the second push rod 10.
