Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to a mud removing device for a planting mechanism. Background Art

[0002] Transplanters, as crucial agricultural tools in modern mechanized agriculture, are widely used in transplanting various crops. Opening and closing duckbill buckets are widely used in transplanter designs due to their simple structure, ease of operation, and adaptability. This type of bucket opens and closes to grasp, transport, and release seedlings from pots, completing the entire transplanting process.

[0003] However, during actual transplanting operations, soil easily clings to the inner walls of the bucket due to varying soil moisture content and its inherent stickiness. When a seedling is dropped into the bucket, if there's any dirt clinging to the inner walls, the seedling may get caught in the clay during its descent, preventing it from landing smoothly in the prepared hole. This situation not only reduces the transplanter's operating efficiency but can also damage the seedling, impacting crop growth and yield.

[0004] To improve the efficiency of transplanters and the survival rate of potted seedlings, ensuring the cleanliness of the inner wall of the duckbill bucket is crucial. Therefore, developing a device that can remove mud from the inner wall of the bucket in real time is of great significance to solving the problems encountered in actual transplanter operations.

[0037] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] The following combination Figure 1 and Figure 2 The present invention provides a planting mechanism mud removal device, which is applied to a transplanter to remove mud from a bucket mechanism 200 during the transplanting process.

[0039] The present invention provides a mud removal device for a planting mechanism. Figure 1 and Figure 2 As shown, the planting mechanism mud removal device includes: a drive mechanism 100, a bucket mechanism 200, a crank-connecting rod mechanism 300, a cam mechanism 400, and a mud removal mechanism 500. The drive mechanism 100 has a first output shaft 101 and a second output shaft 102; the bucket mechanism 200 is used to clamp and fix the seedlings in pots; one end of the crank-connecting rod mechanism 300 is in transmission connection with the first output shaft 101 and the other end is connected to the bucket mechanism 200; the cam mechanism 400 is in transmission connection with the second output shaft 102 and the other end is connected to the bucket mechanism 200, for driving the bucket mechanism 200 to clamp or release the seedlings in pots; the mud removal mechanism 500 is in transmission connection with the cam mechanism 400 and is configured to extend into the bucket mechanism 200 to scrape off attached mud during the process of the bucket mechanism 200 clamping or releasing the seedlings in pots.

[0040] Specifically, the drive mechanism 100 is the power source for the entire device and is equipped with a first output shaft 101 and a second output shaft 102. The bucket mechanism 200 is used to clamp and secure seedlings in pots. These seedlings are planted in a specific container (pot), and the bucket mechanism 200 stably holds these seedlings for subsequent planting or transplanting.

[0041] One end of the crank-connecting rod mechanism 300 is connected to the first output shaft 101 of the driving mechanism 100, and the other end is connected to the bucket mechanism 200. Through the transmission of the crank-connecting rod, the power of the driving mechanism 100 can be controlled to move the bucket mechanism 200 along a predetermined trajectory.

[0042] The cam mechanism 400 is in driving connection with the second output shaft 102 of the drive mechanism 100, and its other end is also connected to the bucket mechanism 200. The design of the cam mechanism 400 enables precise control of the force and timing of the bucket mechanism 200's opening and closing, ensuring that the seedlings in the pots can be clamped or released stably and effectively. The mud removal mechanism 500 is in driving connection with the cam mechanism 400 and is designed to automatically extend into the bucket mechanism 200 to scrape away mud adhering to the seedlings or the bucket during the process of the bucket mechanism 200 clamping or releasing the seedlings in the pots.

[0043] When the drive mechanism 100 is activated, the first and second output shafts 101, 102 rotate synchronously. The first output shaft 101, via the crank-connecting rod mechanism 300, drives the bucket mechanism 200 along a predetermined trajectory. Simultaneously, the second output shaft 102 and cam mechanism 400 complete the opening and closing motions. The second output shaft 102 precisely controls the force and timing of this process via the cam mechanism 400. As the bucket mechanism 200 grips or releases the seedlings from the pots, the desludging mechanism 500, driven by the cam mechanism 400, scrapes away dirt from the seedlings or bucket, ensuring a clean, optimally planted pot.

[0044] For example, during the transplanting process, the bucket mechanism 200 is inserted into the soil and then opened, and the seedlings in the pot fall down; then when it approaches the highest point, the bucket mechanism 200 is closed, and at the same time the mud removal device swings back and enters the bucket mechanism 200 to complete the mud removal action.

[0045] The present invention provides a desilting device for a planting mechanism. The desilting mechanism 500 is in driving connection with the cam mechanism 400. This ensures that, at the critical moment when the bucket mechanism 200 is gripping or releasing the seedlings in the pot, the desilting mechanism 500 can promptly and accurately scrape away any dirt adhering to the inner wall of the bucket. This real-time desilting function effectively prevents seedlings from being unable to settle smoothly into the soil due to adhered dirt, significantly improving transplanting efficiency and seedling survival rate.

[0046] In some embodiments, as Figure 1 and Figure 2As shown, the bucket mechanism 200 includes a bucket opening and closing member 203, a first clamping member 201, and a second clamping member 202. The first clamping member 201 and the second clamping member 202 are arranged opposite each other, forming a clamping space for the seedlings between them. The bucket opening and closing member 203 is connected to the first clamping member 201 and the second clamping member 202. The bucket opening and closing member 203 is connected to the crank-connecting rod mechanism 300 and the cam mechanism 400. The crank-connecting rod mechanism 300 controls the trajectory of the bucket mechanism 200. The relative movement between the crank-connecting rod mechanism 300 and the cam mechanism 400 controls the bucket opening and closing member 203 to drive the relative movement of the first clamping member 201 and the second clamping member 202.

[0047] In this embodiment, the first clamping member 201 and the second clamping member 202 are the main clamping components of the bucket mechanism 200. They are arranged opposite each other, forming a space between them for clamping the seedlings in the pot. The size and shape of this space can be adjusted according to the size and shape of the seedlings in the pot to ensure that the seedlings can be stably and effectively clamped.

[0048] The bucket opening and closing member 203 connects the first clamping member 201 and the second clamping member 202, driving the relative movement of the two. When the bucket opening and closing member 203 moves, it drives the first and second clamping members 201, 202 to move together, thereby clamping or releasing the seedlings in the pot. The bucket opening and closing member 203 is connected not only to the first and second clamping members 201, 202, but also to the crank-connecting rod mechanism 300 and the cam mechanism 400. This connection allows the bucket mechanism 200 to move along a designed trajectory, while precisely controlling the force and timing of the clamping action.

[0049] The power of the drive mechanism 100 drives the entire movement through the transmission of the crank-connecting rod mechanism 300. During this process, the relative movement between the crank-connecting rod mechanism 300 and the cam mechanism 400 can be used to adjust the state switching of the bucket opening and closing member 203, thereby controlling the opening and closing of the bucket mechanism 200 to achieve stable gripping or releasing of the seedlings in the pot.

[0050] In a specific embodiment, if Figure 1 As shown, the first clamping member 201 and the second clamping member 202 are both duckbill clamping members, and the clamping space formed between the two is provided with a gap; when the bin mechanism 200 clamps or releases the seedlings in the pot, the mud removal mechanism 500 extends to the clamping space through the gap to scrape off the attached mud.

[0051] Specifically, the first clamping member 201 and the second clamping member 202 are both designed as duckbill-shaped, which allows them to form a movement similar to the opening and closing of a duck's bill during relative movement. Duckbill-shaped clamping members generally have good elasticity and clamping force, which can stably clamp the seedlings in the pot without causing excessive pressure or damage to the seedlings. A notch is arranged in the clamping space formed between the first clamping member 201 and the second clamping member 202. The notch allows the mud removal mechanism 500 to smoothly extend into the clamping space to scrape off adhering mud when the bucket mechanism 200 clamps or releases the seedlings in the pot.

[0052] When the bucket mechanism 200 grips or releases a seedling pot, the de-mud mechanism 500 activates simultaneously. It precisely controls its movement trajectory and force through a transmission connection with the cam mechanism 400. For example, when the bucket mechanism 200 releases a seedling pot, the de-mud mechanism 500 extends through the gap in the gripping space to the contact surface between the seedling pot and the bucket, scraping off any attached dirt to ensure a smooth drop.

[0053] In some embodiments, as Figure 1 and Figure 2 As shown, the crank-connecting rod mechanism 300 includes a first connecting rod and a crank. One end of the crank is drivingly connected to the first output shaft 101. One end of the first connecting rod is hinged to the other end of the crank, and the other end is connected to the hopper opening and closing member 203. When the crank rotates under the drive mechanism 100, the first connecting rod drives the hopper mechanism 200 along a predetermined trajectory.

[0054] When the first output shaft 101 of the drive mechanism 100 rotates, it drives the crank to rotate. This rotation of the crank further drives the first connecting rod to swing. Because the other end of the first connecting rod is connected to the hopper opening and closing member 203, the swinging of the first connecting rod drives the hopper mechanism 200 to move along a predetermined trajectory.

[0055] By providing a crank-connecting rod mechanism 300, this embodiment enables precise control of the motion trajectory and force of the bucket mechanism 200, thereby improving the efficiency and accuracy of seedling planting. Furthermore, due to its relatively simple and stable structure, the crank-connecting rod mechanism 300 also has high reliability and durability, meeting the requirements of modern agricultural mechanization and automation.

[0056] In some embodiments, as Figure 1 As shown, the cam mechanism 400 includes a cam 401 and a second connecting rod 402. The cam 401 is in transmission connection with the second output shaft 102; one end of the second connecting rod 402 is connected to the cam 401, and the other end is connected to the hopper opening and closing member 203.

[0057] It should be noted that the cam 401 is in transmission connection with the second output shaft 102 of the drive mechanism 100. When the drive mechanism 100 is activated, the second output shaft 102 drives the cam 401 to rotate. The profile design of the cam 401 determines the specific motion pattern it produces during rotation. This pattern enables the cam mechanism 400 to precisely control the movement of the bucket opening and closing member 203. As the cam 401 rotates, it transmits this rotational motion to the bucket opening and closing member 203 via the second connecting rod 402, thereby controlling the opening and closing of the bucket mechanism 200.

[0058] In some embodiments, as Figure 1 As shown, the cam mechanism 400 also includes: an elastic member 600, which is connected between the driving mechanism 100 and the mud removal mechanism 500, one end of the elastic member 600 is connected to the driving mechanism 100 through a pin 601, and the other end of the elastic member 600 is connected to the mud removal mechanism 500, and the mud removal mechanism 500 is rotatably connected to the cam 401 to drive the cam mechanism 400 through the second output shaft 102 to make the mud removal mechanism 500 oscillate.

[0059] In this embodiment, the elastic member 600 mainly functions to provide elastic force to ensure that the mud removal mechanism 500 can perform a yaw motion when the cam 401 rotates.

[0060] When the cam 401 rotates, the elastic member 600 presses the desilting mechanism 500 against the cam 401 via the spring, causing the cam 401 to drive the desilting mechanism 500 to swing. This swinging motion causes the desilting mechanism 500 to follow a different trajectory from the bucket mechanism 200. As the bucket mechanism 200 is gripping or releasing seedlings from the pots, the desilting mechanism 500 extends into the bucket mechanism 200 to scrape off any attached dirt.

[0061] The elastic member 600 is a spring or a spring clip. In the desilting mechanism 500, a spring can be used as the elastic member 600, connected between the drive mechanism 100 and the swing arm 501, to provide the necessary elastic force. Parameters such as the spring's stiffness and length can be adjusted according to actual needs to meet the different requirements of the desilting mechanism 500 for elasticity and cushioning. In the desilting mechanism 500, a spring clip can also be used as the elastic member 600, connected between the drive mechanism 100 and the swing arm 501. Compared to a spring, a spring clip may have a smaller size and a simpler structure.

[0062] In some embodiments, as Figure 1As shown, the second output shaft 102 and cam 401 are connected via an involute spline. Involute splines are a special connection method that allows for a certain range of relative angle adjustment between the two components. The involute spline design allows it to transmit torque while also withstanding certain axial and radial forces. This connection ensures a reliable connection between the second output shaft 102 and cam 401, allowing for a certain range of relative angle adjustment.

[0063] When the timing between the movement of the hopper mechanism 200 and the demud removal of the demud removal mechanism 500 is not in sync, the problem can be solved by adjusting the installation angle of the cam 401 .

[0064] In some embodiments, as Figure 1 and Figure 2 As shown, the desilting mechanism 500 includes a swing arm 501 and a desilting rod 502. One end of the swing arm 501 is rotatably connected to the cam 401 via a bearing 504, and the elastic member 600 is connected between the drive mechanism 100 and the swing arm 501. The desilting rod 502 is connected to the other end of the swing arm 501. When the bucket mechanism 200 is gripping or releasing the seedlings from the pot, the desilting rod 502 extends into the bucket mechanism 200 to scrape off any attached dirt.

[0065] Specifically, when the cam 401 rotates under the action of the driving mechanism 100, the swing arm 501 will swing accordingly, thereby driving the mud removal rod 502 to move. The design of the swing arm 501 needs to take into account factors such as its length, strength and rigidity to ensure that the mud removal mechanism 500 can stably and effectively scrape off the mud attached to the seedling pot or the bucket. The elastic member 600 is connected between the driving mechanism 100 and the swing arm 501. Its function is to provide elasticity to ensure that the mud removal mechanism 500 can maintain a smooth motion trajectory during the swinging process. The mud removal rod 502 is connected to the other end of the swing arm 501 and is the component that actually performs the mud scraping action.

[0066] When the bucket mechanism 200 is gripping or releasing the seedlings from the pot, the de-mud rod 502 extends into the bucket mechanism 200 to scrape off the attached mud. The design of the de-mud rod 502 needs to take into account factors such as its material, shape, and size to ensure that it can effectively scrape off the mud without damaging the seedlings or the bucket.

[0067] If needed, a rubber block 503 can be installed on the desilting rod 502. The rubber block 503 increases the friction between the desilting rod 502 and the seedling pot or bucket, thereby improving the mud scraping effect. At the same time, the rubber block 503 also has a certain degree of elasticity and cushioning effect, which can protect the seedling pot or bucket from damage.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
