Description

Technical Field

[0001] This invention relates to the field of seedling tray recycling technology, specifically to a device for recycling the friction of empty seedling trays in a rice transplanter. Background Technology

[0002] A rice transplanter is a new type of agricultural machinery whose main function is to transplant rice seedlings in an orderly manner. This machinery can not only reduce the labor intensity of farmers and improve work efficiency, but also improve the planting quality of rice and increase yield. In addition, the rice transplanter has the advantages of early tillering, low tillering node, and more tillers, effectively solving the problems of long seedling establishment period, slow greening, and late tillering that exist in traditional rice transplanting methods.

[0003] The existing rice transplanter needs to be mounted on a small cart that can travel in the paddy field to achieve the effect of transplanting rice seedlings while moving. Due to the limited space on the cart and the small distance between the transplanter and the cart's bottom plate, the empty seedling trays fall directly below the transplanter after being discharged. The empty seedling trays need to be collected manually. Otherwise, the empty seedling trays will quickly accumulate and block the discharge tray holes of the transplanter. In other words, an assistant is needed on the cart to manually collect the empty seedling trays during transplanting, which is time-consuming and labor-intensive. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a rice transplanter empty disc friction recovery device, including a right conveyor located below the rice transplanter, two friction wheel sets as a pair, several pairs of friction wheel sets forming an arc, a guide strip passing through the gap between several pairs of friction wheel sets, and a collection bag fixedly installed below the top of the guide strip.

[0005] The friction wheel assembly includes a shaft, on which two friction wheels and gears are sleeved. The distance between the two friction wheels on the same side of the same pair is less than the thickness of the seedling tray. The gears of the inner friction wheel assembly and the gears of the outer friction wheel assembly are connected by transmission chains. The outer motor is connected to one shaft of the inner friction wheel assembly, and the inner motor is connected to one shaft of the outer friction wheel assembly.

[0006] Preferably, it also includes a left conveyor and a translation mechanism. The left conveyor is located below the rice transplanter, and the right conveyor is located to the side of the left conveyor. The translation mechanism is located above the left and right conveyors and is used to move the seedling tray from the left conveyor to the right conveyor. A rear baffle is fixedly installed at the top of the tail end of the left conveyor, and a side baffle is fixedly installed at the top of the right conveyor on the side away from the left conveyor.

[0007] Preferably, the translation mechanism includes a linear module, a telescopic cylinder, and a contact element. The linear module is fixedly located above the left and right conveyors. A telescopic cylinder with a vertical driving direction is fixedly installed on the drive end of the linear module, and the contact element is fixedly installed on the drive end of the telescopic cylinder.

[0008] Preferably, there are two telescopic cylinders, which are located on opposite sides of the driving end of the linear module. The contact element is located directly below the linear module and is fixedly connected to the two telescopic cylinders. The bottom part of the contact element consists of two parallel straight rods. The distance between the two straight rods is a multiple of the distance between two protrusions in the same row of the seedling tray, and the maximum distance does not exceed the width of the seedling tray.

[0009] Preferably, the translation mechanism further includes a guide tube and a guide post. The guide tube is fixed to the drive end of the linear module, and the guide post is fixed to the drive end of the telescopic cylinder with one end passing through the guide tube. The guide post is adapted to the guide tube and is vertical.

[0010] Preferably, it also includes a bracket, the friction wheel assembly is mounted on the bracket, the collection bag is fixedly mounted on the bracket and has an open top, and the bottom of the collection bag is provided with a discharge port.

[0011] Preferably, there are two guide strips, which are parallel to each other and the distance between them is less than the width of the seedling tray. The guide strips are located in the gap between several pairs of friction wheel sets on the side of the outer friction wheel set.

[0012] Preferably, the length of the guide strip between two adjacent friction wheel sets on the same side is less than the length of the seedling tray.

[0013] Preferably, the external motor and the internal motor have the same rotational speed but opposite driving directions.

[0014] The present invention has the following beneficial effects:

[0015] After the empty seedling tray falls onto the right conveyor, it is moved by the right conveyor to the gap between the bottom pair of friction wheels. The friction wheels rotate to clamp the empty seedling tray and move it along the length of the guide bar. After the empty seedling tray moves to another pair of friction wheels, it is clamped by the other pair and continues to move until the empty seedling tray reaches the top of the guide bar and falls from the top of the guide bar into the collection bag, thus completing the recycling of the empty seedling tray. The whole process does not require manual intervention, saving time and effort. Moreover, the empty seedling tray will not accumulate under the seedling thrower, avoiding blockage or jamming at the seedling thrower's tray outlet. Attached Figure Description

[0021] The principles and features of the present invention are described below. The embodiments given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0022] It should be noted that when a part or component is considered to be "connected to," "located on," or "assembled" to another part or component, it can be directly mounted on the other part or component, or it may be located in an intermediate part or component. The terms "left," "right," "upper," "lower," and similar expressions used in this document are for illustrative purposes only.

[0023] In one specific implementation, such as Figure 1-3 As shown, a rice transplanter empty disc friction recovery device includes a right conveyor 2 located below the rice transplanter, two friction wheel sets 4 as a pair, several pairs of friction wheel sets 4 forming an arc, a guide strip 5 passing through the gap between several pairs of friction wheel sets 4, and a collection bag 8 fixedly installed below the top of the guide strip 5.

[0024] The friction wheel assembly 4 includes a shaft 401, on which two friction wheels 402 and gears 403 are sleeved. The distance between the two friction wheels 402 on the same side of the same pair is less than the thickness of the seedling tray. The gears 403 adjacent to each other in the inner friction wheel assembly 4 and the gears 403 adjacent to each other in the outer friction wheel assembly 4 are respectively connected by a transmission chain. The outer motor 6 is connected to one shaft 401 in the inner friction wheel assembly 4, and the inner motor 7 is connected to one shaft 401 in the outer friction wheel assembly 4.

[0025] In this embodiment, a left conveyor 1 and a translation mechanism 3 are also included. The left conveyor 1 is located below the rice transplanter, and the right conveyor 2 is located to the side of the left conveyor 1. The translation mechanism 3 is located above the left conveyor 1 and the right conveyor 2 and is used to move the seedling tray from the left conveyor 1 to the right conveyor 2. A rear baffle 101 is fixedly installed on the top of the tail end of the left conveyor 1, and a side baffle 201 is fixedly installed on the top of the side of the right conveyor 2 away from the left conveyor 1. During use, the right conveyor 2, the friction wheel assembly 4, and the collection bag 8 are positioned to the side of the rice transplanter, i.e., to the side of the driver's seat, to prevent the collection bag 8 from obstructing the driver's view from being located in front of the driver's seat.

[0026] The left conveyor 1 and the right conveyor 2 operate in the same direction. The left conveyor 1 moves the empty seedling tray to the tail end and contacts the rear baffle 101. The translation mechanism 3 translates the seedling tray onto the right conveyor 2 and contacts the side baffle 201. The right conveyor 2 moves the seedling tray to contact the friction wheel assembly 4. The distance between the rear baffle 101 and the side baffle 201 is adapted to the width of the seedling tray, so that the seedling tray can only enter the guide bar 5 and contact the friction wheel assembly 4 through the gap between the rear baffle 101 and the side baffle 201 after contacting the side baffle 201 and undergoing posture correction.

[0027] Furthermore, the translation mechanism 3 includes a linear module 301, a telescopic cylinder 302, a contact element 303, and a mounting frame 304. The mounting frame 304 is U-shaped and inverted above the left conveyor 1 and the right conveyor 2. The linear module 301 is fixedly installed on the mounting frame 304 and is perpendicular to the running direction of the left conveyor 1 and the right conveyor 2. The telescopic cylinder 302 with a vertical driving direction is fixedly installed on the driving end of the linear module 301, and the contact element 303 is fixedly installed on the driving end of the telescopic cylinder 302.

[0028] Specifically, there are two telescopic cylinders 302, located on opposite sides of the driving end of the linear module 301. The contact element 303 is located directly below the linear module 301 and is fixedly connected to the two telescopic cylinders 302, ensuring uniform force distribution on the telescopic cylinders 302 and preventing unintentional changes in posture such as tilting of the contact element 303. The two telescopic cylinders 302 operate synchronously to drive the contact element 303 to rise or fall. The bottom part of the contact element 303 consists of two parallel straight rods, perpendicular to the rear baffle 101 and parallel to the side baffle 201. The distance between the two straight rods is a multiple of the distance between two protrusions in the same row of the seedling tray, with a maximum distance not exceeding the width of the seedling tray. This allows both straight rods to smoothly enter the gap between the two rows of protrusions in the seedling tray when the telescopic cylinder 302 drives the contact element 303 to descend. Then, the linear module 301 is activated to move the seedling tray until it contacts the side baffle 201, after which the telescopic cylinder 302 resets, causing the contact element 303 to detach from the seedling tray.

[0029] Furthermore, the translation mechanism 3 also includes a guide tube 305 and a guide post 306. The guide tube 305 is fixed to the driving end of the linear module 301, and the guide post 306 is fixed to the driving end of the telescopic cylinder 302 with one end passing through the guide tube 305. The guide post 306 is adapted to the guide tube 305 and is vertical, which helps to fix the moving direction of the contact member 303 and prevents the contact member 303 from shaking.

[0030] In this embodiment, a bracket 9 is also included. The friction wheel assembly 4 is mounted on the bracket 9. The collection bag 8 is fixedly mounted on the bracket 9 and has an open top. The bottom of the collection bag 8 is provided with a discharge port. When filling, the discharge port can be tied in a knot or tied with a rope. When unloading, the discharge port can be opened, which is convenient and practical.

[0031] In this embodiment, the length of the guide strip 5 between two adjacent friction wheel sets 4 on the same side is less than the length of the seedling tray. That is, when the seedling tray is driven by several friction wheel sets 4 to move along the length direction of the guide strip 5, at least one pair of friction wheel sets 4 is always in contact with the seedling tray to continue moving the seedling tray.

[0032] In this embodiment, there are two guide strips 5. The two guide strips 5 are parallel to each other and the distance between them is less than the distance between the two friction wheels 402 on the same friction wheel set 4. In other embodiments, it is sufficient to ensure that the distance between the two guide strips 5 is less than the width of the seedling tray. The guide strips 5 are located on the outer side of the friction wheel set 4 in the gap between the several pairs of friction wheel sets 4, so that the seedling tray is located in the middle of the gap between the several pairs of friction wheel sets 4.

[0033] The external motor 6 and the internal motor 7 drive in opposite directions, and their rotational speeds are the same.

[0034] The above-mentioned rice transplanter empty disc friction recovery device can be further optimized and / or improved according to actual needs:

[0035] The right conveyor 2 rotates at a higher speed than the left conveyor 1 to quickly and completely feed the seedling trays onto the guide bar 5, preventing the seedling trays from being blocked from moving the next tray if they are not fed in time.

[0036] In summary: After the empty seedling tray falls onto the right conveyor 2, it is moved by the right conveyor 2 to the gap between the bottom pair of friction wheel sets 4. The friction wheel sets 4 rotate to clamp the empty seedling tray and move it along the length of the guide strip 5. After the empty seedling tray moves to another pair of friction wheel sets 4, it is clamped by the other pair of friction wheel sets 4 and continues to move until the empty seedling tray reaches the top of the guide strip 5 and falls from the top of the guide strip 5 into the collection bag 8, thus completing the recycling of the empty seedling tray. The whole process does not require manual intervention, saving time and effort. Moreover, the empty seedling tray will not accumulate under the seedling thrower, avoiding blockage or jamming at the seedling thrower's tray outlet.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, using the disclosed technical content, are equivalent embodiments of the present invention. Furthermore, any modifications, alterations, or variations made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the present invention.
