Description

Technical Field

[0001] This utility model relates to the field of rice transplanter technology, specifically to an automatic rice transplanter and fertilizer application device for a rice transplanter. Background Technology

[0002] Rice transplanters are mainly used in agricultural production, especially in rice planting, to improve transplanting efficiency and quality. Their working principle is to use a series of mechanical structures and power devices to orderly remove seedlings from the seedling box and insert them into the paddy field soil.

[0003] A search revealed an automatic rice transplanting and fertilizing device for a rice transplanter, patent publication number "CN 213306217 U". This device includes a mounting plate with a seedling box on it. A seedling lowering pipe is connected to the bottom of the seedling box, and a movable part is connected to the left side of the lowering pipe. This invention utilizes a first electric telescopic rod, an air pump, a seedling clamp, and a sponge-material clamping block. After the seedlings are discharged from the seedling box by the seedling feeder, the air pump drives the clamping block on the seedling clamp to hold the seedlings. Then, the first electric telescopic rod drives the seedlings to insert into the ground. After the seedling clamp releases, the seedlings remain in the mud. Simultaneously, a second electric telescopic rod, in conjunction with the first electric telescopic rod, tilts and moves the seedling clamp out. After resetting, a second transplanting can be performed. The transplanting depth can be adjusted according to the extension of the first electric telescopic rod, making it convenient to use.

[0004] The above technical features have the following shortcomings: The device is designed with a first telescopic rod, a clamping block, a second telescopic rod, and a movable rod to achieve automatic rice transplanting. Simultaneously, after the clamping block inserts the seedling into the soil, it releases the gas from the air pipe. At this point, the clamping block releases the seedling, and the second telescopic rod pushes the first telescopic cylinder and the mesh frame outwards to pull it out of the soil, completing the integrated rice transplanting operation. However, in actual operation, the movable rod and clamping block lose control after the gas is released from the air pipe. When pulling out the seedling, problems may arise such as pulling it out again or causing it to deviate from its intended position. Furthermore, the overall operation is not coordinated enough, affecting work efficiency.

[0005] Therefore, an automatic rice transplanting and fertilization device for rice transplanters is proposed. Utility Model Content

[0006] The purpose of this invention is to provide an automatic rice transplanting and fertilization device for a rice transplanter to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic rice transplanting and fertilizing device for a rice transplanter, comprising a seedling tube and a fertilizer tube, wherein a cylinder is connected to the outer wall of the seedling tube, a fixed seat is connected to the output end of the cylinder, a clamping plate is rotatably connected to the interior of the fixed seat, a rotating block is rotatably connected to the outer walls of the two clamping plates, a limit spring is connected to the outer walls of a corresponding set of rotating blocks, a connecting block is connected to the outer walls of a corresponding set of rotating blocks, a telescopic block is connected to the upper end of the two connecting blocks, and a guide component is coupled to the other end of the two telescopic blocks.

[0008] Preferably, the guiding component includes a guide plate, the interior of which two sets of first and second sliding grooves are formed opposite to each other. The interiors of each set of first and second sliding grooves are connected. The depth of the upper end of the second sliding groove is higher than the depth of the interior of the first sliding groove. The fixed seat is pushed down by a cylinder, which causes the telescopic block to slide from the first sliding groove into the interior of the second sliding groove. This allows the seedlings held by the clamps to spread out to both sides and release the seedlings after they are inserted into the soil. At the same time, under the action of the second sliding groove, the clamps on both sides are controlled to return to the clamping state to prevent the seedlings from being pulled out.

[0009] Preferably, a connecting shaft is installed inside each of the two clamping plates, and the two connecting shafts are rotatably installed inside the fixed seat. The lower end of the fixed seat is positioned between the two connecting shafts for material feeding.

[0010] Preferably, the outer wall of the fertilizer pipe is connected to a metering valve to control the metered feeding of fertilizer.

[0011] Preferably, the guide plate is fixedly installed on the seedling tube, a fixing plate is installed on the outer wall of the cylinder, the fixing plate is fixedly installed on the seedling tube, and the seedling tube and the fertilizer tube are internally connected to each other.

[0012] Preferably, guide blocks are connected to the lower part of the inner walls of both clamps, and the inner sidewalls of both guide blocks are tapered, so that the seedlings are smoothly clamped in the center of the two clamps, ensuring that the seedlings are vertical and neat after insertion.

[0013] Preferably, the lower ends of both clamps are connected to conical plugs, which are set as inverted cones in the normal clamping state to avoid large stones or hard objects during rice planting.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model effectively solves the problem of seedlings being easily pulled out or misaligned in the prior art by setting up a guide component. The first and second sliding grooves inside the guide plate of the guide component are interconnected and have different depths. During the transplanting process, the cylinder pushes the fixed seat down, causing the telescopic block to slide from the first sliding groove into the second sliding groove. This allows the seedlings held by the clamps to spread out to both sides and release the seedlings after they are inserted into the soil. At the same time, under the action of the second sliding groove, the clamps on both sides are controlled to return to the clamping state, avoiding the situation of pulling out the seedlings, improving the accuracy and stability of transplanting, ensuring that the seedlings can be firmly inserted into the soil, which is beneficial to the growth and development of the seedlings.

[0016] 2. The coordinated operation of the various components of this utility model significantly improves the efficiency and quality of rice transplanting. The guide block at the bottom of the inner wall of the clamp is set in a cone shape, so that the seedlings can be smoothly clamped in the center of the two clamps, ensuring that the seedlings are vertical and neat after insertion.

[0017] In addition, the conical plug at the lower end of the clamp is set as an inverted cone in the normal clamping state, which can effectively avoid damage to the seedlings caused by large stones or hard objects during the transplanting process. During the transplanting process, all parts of the device work closely together and move smoothly, reducing unnecessary operation steps and time, thereby improving transplanting efficiency, reducing labor intensity, and ensuring the quality of transplanting, laying a good foundation for high and stable rice yields.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: an automatic rice transplanting and fertilizing device for a rice transplanter, including a seedling tube 1 and a fertilizer tube 14. A cylinder 12 is connected to the outer wall of the seedling tube 1. A fixed seat 11 is connected to the output end of the cylinder 12. A clamping plate 9 is rotatably connected to the inside of the fixed seat 11. Rotating blocks 7 are rotatably connected to the outer walls of the two clamping plates 9. A limit spring 8 is connected to the outer walls of a set of rotating blocks 7. A connecting block 6 is connected to the outer walls of a set of rotating blocks 7. A telescopic block 5 is connected to the upper end of the two connecting blocks 6. A guide component is coupled to the other end of the two telescopic blocks 5.

[0025] The guiding component includes a guide plate 2. The guide plate 2 has two sets of first sliding grooves 3 and second sliding grooves 4 arranged opposite each other inside. The interiors of each set of first sliding grooves 3 and second sliding grooves 4 are connected. The upper depth of the second sliding groove 4 is greater than the depth of the first sliding groove 3. The lower end of the second sliding groove 4 is flush with the inner wall of the first sliding groove 3. The middle of the two second sliding grooves 4 is recessed, allowing the telescopic block 5 to slide smoothly into the interior of the second sliding groove 4. The cylinder 12 pushes the fixed seat 11 downwards, causing the telescopic block 5 to slide from the first sliding groove 3 into the interior of the second sliding groove 4. This allows the seedlings held by the clamping plates 9 to be inserted into the soil, then spread out to both sides and release the seedlings. Simultaneously, under the action of the second sliding grooves 4, the clamping plates 9 on both sides are controlled to return to the clamping state, preventing the seedlings from being pulled out. It should also be noted that before transplanting, the cylinder 12 drives the connecting block 6 and the telescopic block 5 to move upwards and spread out to both sides, allowing the seedlings to fall smoothly between the clamping plates 9. This makes the overall transplanting operation more coordinated, more efficient, and saves on input costs.

[0026] In this embodiment, a connecting shaft 16 is installed inside both clamping plates 9, and both connecting shafts 16 are rotatably installed inside the fixed seat 11. The lower end of the fixed seat 11 is located between the two connecting shafts 16 for material feeding.

[0027] In this embodiment, a metering valve 15 is connected to the outer wall of the fertilizer pipe 14 to control the metered feeding of fertilizer.

[0028] In this embodiment, the guide plate 2 is fixedly installed on the seedling tube 1, and a fixing plate 13 is installed on the outer wall of the cylinder 12. The fixing plate 13 is fixedly installed on the seedling tube 1, and the seedling tube 1 and the fertilizer tube 14 are internally connected to each other.

[0029] In this embodiment, guide blocks 10 are connected to the lower part of the inner walls of the two clamping plates 9. The inner sidewalls of the two guide blocks 10 are conical, so that the seedlings can be smoothly clamped in the center of the two clamping plates 9, ensuring that the seedlings are vertical and neat after insertion.

[0030] Both clamping plates 9 are connected to a conical plug 17 at their lower ends. The two conical plugs 17 are set as inverted cones in the normal clamping state to avoid large stones or hard objects during the transplanting of rice seedlings.

[0031] The working principle is as follows: The automatic rice transplanting and fertilizing device for rice transplanters provided by this utility model operates as follows: First, the seedlings in the lower tube 1 are clamped by the fixed seat 11 driven by the cylinder 12, pushing them up and down. As the cylinder 12 pushes the fixed seat 11 down, the telescopic block 5 slides from the first slide groove 3 of the guide component into the second slide groove 4, causing the seedlings clamped by the clamp 9 to spread out and loosen to both sides after being inserted into the soil. Then, under the action of the second slide groove 4, the clamp 9 on both sides returns to the clamping state, preventing the seedlings from being pulled out. This solves the problem of seedlings being easily pulled out or pulled off course in the prior art. At the same time, the guide block 10 below the inner wall of the clamp 9 is cone-shaped, which helps the seedlings to be clamped smoothly in the center, ensuring that the inserted seedlings hang vertically. The rice seedlings are straight and neat. In addition, the conical plug 17 at the lower end of the clamping plate 9 is an inverted cone in the normal clamping state, which can prevent damage to the seedlings from stones or hard objects during transplanting. The metering valve 15 on the outer wall of the fertilizer tube 14 controls the metered feeding of fertilizer, so that transplanting and fertilization can be carried out simultaneously. The seedling tube 1 and the fertilizer tube 14 are interconnected to ensure that the seedlings and fertilizer can reach the designated position at the same time. The guide plate 2 is fixedly installed on the seedling tube 1, and the fixing plate 13 on the outer wall of the cylinder 12 is also fixed on the seedling tube 1 to ensure the stability of the entire device. Through the coordinated work of the above components, this device not only improves the accuracy and stability of transplanting, but also improves the efficiency and quality of transplanting, reduces labor intensity, and provides an efficient and convenient solution for rice planting.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
