Description

Technical Field

[0001] This utility model relates to the field of sugarcane planting technology, specifically to a discharge device for sowing sugarcane seeds. Background Technology

[0002] However, traditional manual sugarcane cultivation is not only labor-intensive but also extremely demanding. With the acceleration of agricultural modernization, the mechanization of sugarcane cultivation is urgently needed. Currently, although my country's agricultural machinery technology has made some progress, the overall level of mechanization in sugarcane cultivation still needs significant improvement.

[0003] Most existing pre-cut seed sugarcane planters rely on two drive chains to lift sugarcane seeds and then drop them directly onto the sugarcane field. In practice, because the conveyor chains cannot maintain a uniform number of seeds while lifting them, the seeds cannot be discharged one by one in an orderly manner, resulting in frequent uneven sugarcane discharge and serious seeding problems.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide a discharge device for sowing sugarcane seeds, so as to solve the problems mentioned in the background art.

[0007] The seed dispensing chute has a straight section located below the seed dispensing opening and an inclined section extending at one end of the straight section. The length of the inclined section is sufficient to accommodate at least two sugarcane seeds. A transmission roller rotates symmetrically inside the straight section, and a transmission belt is connected between the two transmission rollers.

[0008] A gate is located at the port of the inclined section away from the straight section. It can slide back and forth vertically along the vehicle body to open / close the port of the inclined section. A drive assembly for driving its back and forth sliding is also provided on the vehicle body.

[0009] The inclined section has a sliding rod slidably connected to its side wall, and a connecting rod is connected to one end of the sliding rod that extends to the outside of the straight section. The gate plate has an inclined groove, and the connecting rod is slidably connected inside the inclined groove.

[0010] Furthermore, the driving component includes;

[0011] The secondary gear is rotatably mounted on the upper part of the vehicle body, at a certain height from the top surface of the vehicle body;

[0013] Furthermore, the driving component also includes,

[0014] Two synchronous pulleys, one of which is mounted on the axle of the wheel, and the other is connected to the roller shaft of the transmission roller. A transmission belt connects the two synchronous pulleys.

[0015] The worm gear is rotatably mounted on the side wall of the straight section, and the worm gear is coaxially arranged with the synchronous pulley;

[0016] A rotating shaft is rotatably mounted on the side wall of the straight section. One end of the shaft is connected to a worm gear that meshes with the worm, and the other end is connected to a main gear that meshes with the secondary gear.

[0023] A partition is installed inside the box to divide the box cavity into two equal-sized receiving cavities. The seed discharge port is located at the bottom of the box and corresponds to the receiving cavity.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] 1. This utility model, through the special design of the seed discharging slide, the limitation of the number of seeds that can be accommodated by the inclined section, and the coordinated control of the movement of the conveyor belt and the gate, effectively avoids the problem of disorderly falling and accumulating of seeds in the traditional method, ensuring that sugarcane seeds can be discharged from the device one by one in an orderly manner, improving the uniformity and accuracy of seed discharging, reducing the phenomenon of missed seeds, and providing a good foundation for the uniform planting and subsequent growth of sugarcane.

[0032] 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.

[0033] Please see Figures 1-4 The present invention provides a technical solution: a discharge device for sowing sugarcane seeds, including a vehicle body 1, the vehicle body 1 being connected to wheels via a rotating shaft, a sugarcane seed box 3 being fixed to the upper part of the vehicle body 1, a seed discharge port 34 being provided at the lower part of the sugarcane seed box 3, and a discharge assembly being provided on the vehicle body 1, the discharge assembly including;

[0034] The seed dispensing chute 4 has a straight section 41 located below the seed dispensing port 34 and an inclined section 42 extending at one end of the straight section 41. The length of the inclined section 42 is sufficient to accommodate at least two sugarcane seeds. A transmission roller 43 rotates symmetrically inside the straight section 41, and a transmission belt 44 is connected between the two transmission rollers 43.

[0035] A gate 12 is located at the port of the inclined section 42 away from the straight section 41. It can slide back and forth vertically along the vehicle body 1 to open / close the port of the inclined section 42. A drive assembly for driving its back and forth sliding is also provided on the vehicle body 1.

[0036] Among them, a sliding rod 16 is slidably connected to the side wall of the inclined section 42, and a connecting rod 15 is connected to one end of the sliding rod 16 extending to the outside of the straight section 41. An inclined groove 13 is opened on the gate plate 12, and the connecting rod 15 is slidably connected inside the inclined groove 13.

[0037] Specifically, sugarcane seeds are stored in the seed box 3 and fall onto the straight section 41 of the seed discharge chute 4 through the seed discharge port 34; the symmetrically rotating transmission roller 43 inside the straight section 41 drives the transmission belt 44 to rotate, and the transmission belt 44 transports the sugarcane seeds from the straight section 41 to the inclined section 42.

[0038] The inclined section 42 is long enough to hold at least two sugarcane seeds. When the sugarcane seeds are transferred to the inclined section 42, they will slide down naturally due to the inclined design of the section. The gate 12 is located at the port of the inclined section 42 away from the straight section 41. When the gate 12 is open, the port of the inclined section 42 is open, and the sugarcane seeds are discharged from the port. When the gate 12 is closed, the port is closed, and the seeds cannot be discharged. The sliding rod 16 cooperates with the inclined groove 13 on the gate 12 through the connecting rod 15. When the gate 12 slides up and down, the sliding rod 16 will slide on the side wall of the inclined section 42 accordingly. The setting of the seed discharge slide 4, through the cooperation of the straight section 41 and the inclined section 42, allows the sugarcane seeds to be transferred orderly from the seed box 3 to the discharge port. Compared with the direct falling method in the prior art, it improves the orderliness of seed discharge to a certain extent. The setting of the gate 12 can control the discharge of sugarcane seeds. The seed discharge port can be opened or closed according to actual needs, which makes it easy to control the time and quantity of seed discharge and reduce the occurrence of missed seeds.

[0039] See Figure 3 The driving components include;

[0040] The secondary gear 10 is rotatably mounted on the upper part of the vehicle body 1, at a certain height from the top surface of the vehicle body 1;

[0041] The connecting rod 11 is rotatably connected to the front end face of the auxiliary gear 10, and the end of the connecting rod 11 away from the auxiliary gear 10 is hinged to the top of the gate plate 12.

[0042] Specifically, the secondary gear 10 is rotatably mounted on the upper part of the vehicle body 1. When the secondary gear 10 rotates, the connecting rod 11 rotatably connected to its front end face will move accordingly. The end of the connecting rod 11 away from the secondary gear 10 is hinged to the top of the gate plate 12. The movement of the connecting rod 11 drives the gate plate 12 to slide vertically back and forth along the vehicle body 1, thereby realizing the opening and closing of the gate plate 12 to the inclined section 42 port. The drive assembly composed of the secondary gear 10 and the connecting rod 11 provides a simple and effective driving method for the movement of the gate plate 12. The structure is relatively simple, easy to implement and maintain. By controlling the rotation of the secondary gear 10, the opening and closing time of the gate plate 12 can be precisely controlled, thereby more accurately controlling the discharge of sugarcane seeds.

[0043] See Figure 3 The driver components also include,

[0044] Two synchronous pulleys, one of which is mounted on the wheel axle and the other is connected to the roller shaft of the transmission roller 43. A transmission belt 5 is connected between the two synchronous pulleys.

[0045] Worm 6 is rotatably mounted on the side wall of the straight section 41, and worm 6 is coaxially arranged with the synchronous pulley;

[0046] The rotating shaft 7 is rotatably mounted on the side wall of the straight section 41. One end of the shaft is connected to a worm wheel 8 that meshes with the worm 6, and the other end is connected to a main gear 9 that meshes with the secondary gear 10.

[0047] Specifically, the rotation of the wheels serves as the power source for the entire system. Through the transmission connection of the synchronous pulley, transmission belt 5, worm 6, worm wheel 8, main gear 9, and auxiliary gear 10, the transmission of sugarcane seeds on the conveyor belt 44 and the movement of the gate 12 are realized. The power is rationally distributed and transmitted, making the operation of the entire discharge device more coordinated. This transmission method can establish a certain correlation between the transmission of sugarcane seeds and the movement of the gate 12, ensuring the accuracy and orderliness of seed dispensing and further reducing the problems of missed seeds and uneven seed dispensing.

[0048] See Figure 3 A mounting bracket is provided on the side wall of the straight section 41, and the mounting bracket extends vertically along the side wall of the straight section 41. The worm gear 6 is rotatably connected to the mounting bracket.

[0049] Specifically, the installation support ensures the installation stability of the worm gear 6, preventing it from shaking or becoming unstable during rotation, thus ensuring the stability and reliability of the entire transmission system and the normal operation of the discharge device.

[0050] See Figure 3The end of the connecting rod 15 away from the slide rod 16 is connected to the follower rod 14. The follower rod 14 is slidably connected inside the inclined groove 13. The connecting rod 15 is connected to the inclined groove 13 through the follower rod 14.

[0051] Specifically, the setting of the follower rod 14 increases the connection stability and flexibility between the connecting rod 15 and the inclined groove 13, so that the connecting rod 15 can move more smoothly with the movement of the gate 12, ensuring the transmission effect between the slide rod 16 and the gate 12, and further improving the stability and reliability of the movement of the gate 12.

[0052] See Figure 3 The slide bar 16 extends into the interior of the connecting rod 15 and is connected to a clamping plate 17, which is made of rubber.

[0053] Specifically, it acts as a buffer to prevent the slide bar 16 from making hard contact with the sugarcane seed.

[0054] See Figure 1 A bracket 2 is installed on the top of the vehicle body 1, and the sugarcane seed box 3 is fixedly installed on the bracket 2.

[0055] Specifically, the bracket 2 ensures the installation stability of the sugarcane seed box 3, preventing the sugarcane seed box 3 from shaking or becoming unstable during the movement of the vehicle body 1, which helps to ensure the accuracy and stability of the seeding.

[0056] See Figure 2 and Figure 4 The sugarcane seed box 3 includes,

[0057] The box 31 is mounted on the bracket 2 and has a cavity inside for holding sugarcane seeds;

[0058] A partition 32 is installed inside the box 31 to divide the cavity of the box 31 into two equal-sized receiving cavities 33. The seed discharge port 34 is located at the bottom of the box 31 and corresponds to the receiving cavity 33.

[0059] Specifically, when it is necessary to plant, sugarcane seeds fall from the receiving cavity 33 through the seed outlet 34 onto the seed chute 4. The inside of the sugarcane seed box 3 is equipped with a partition 32, which divides it into two receiving cavities 33 of the same size, allowing for the simultaneous planting of two rows of sugarcane seeds and improving planting efficiency.

[0060] Working principle:

[0061] Sugarcane seeds are pre-stored in a seed box 3, which is securely mounted on top of a vehicle body 1 using a bracket 2. The vehicle body 1 can move within the planting area using its wheels. The seed box 3 has a partition 32 that divides it into two identical accommodating chambers 33, allowing for the simultaneous planting of two rows of sugarcane seeds and improving planting efficiency. Each accommodating chamber 33 has a corresponding seed outlet 34 at its bottom, ensuring that the seeds fall orderly into the subsequent transport structure.

[0062] When the vehicle body 1 begins to move, the wheels rotate, causing the synchronous pulleys mounted on the wheel axles to rotate synchronously. This synchronous pulley establishes a transmission relationship with another synchronous pulley connected to the shaft of the transmission roller 43 via the transmission belt 5, thereby driving the transmission roller 43 to rotate and causing the transmission belt 44 to start working. Sugarcane seeds fall smoothly from the seed outlet 34 of the seed box 3 onto the straight section 41 of the seed outlet slide 4, officially starting the seed transfer process;

[0063] The conveyor belt 44 operates continuously and stably, pushing the sugarcane seeds from the straight section 41 of the seed dispensing chute 4 to the inclined section 42. The inclined section 42 is designed to be long enough to hold at least two sugarcane seeds. This ingenious design limits the number of seeds piled up in the chute, ensuring that the seeds maintain a certain distance during the transmission process, thus initially achieving orderly arrangement and laying the foundation for subsequent precise seeding.

[0064] The worm 6, which is coaxial with the synchronous pulley, rotates as the synchronous pulley rotates. The worm 6 meshes with the worm wheel 8, driving the rotating shaft 7 to rotate. The main gear 9 connected to the other end of the rotating shaft 7 meshes with the secondary gear 10, causing the secondary gear 10 to rotate. The connecting rod 11, which is rotatably connected to the front end face of the secondary gear 10, moves along with the secondary gear 10 as it rotates, ultimately driving the gate 12 to slide vertically back and forth along the vehicle body 1, thereby realizing the opening and closing operation of the inclined section 42 port.

[0065] A sloping groove 13 is provided on the gate 12. A connecting rod 15 is slidably connected within the sloping groove 13 via a follower rod 14. The other end of the connecting rod 15 is connected to a sliding rod 16, which is mounted on the side wall of the inclined section 42 and can slide along the side wall. When the gate 12 is opened, the port of the inclined section 42 opens, and a single sugarcane seed located at the port is discharged under gravity. At the same time, the sliding rod 16 moves under the drive of the connecting rod 15, which can clamp another sugarcane seed in the sloping groove 13, effectively preventing two seeds from falling at the same time. When the gate 12 is closed, the port is closed, and the seed discharge stops. Furthermore, since the movement of the gate 12 and the conveyor belt 44 is closely linked through a series of transmission structures, it is ensured that only a single seed located at the port of the inclined section 42 can be discharged each time the gate 12 is opened. This fundamentally ensures that the sugarcane seeds are discharged one by one in an orderly manner, improving the accuracy and uniformity of seed distribution and meeting the requirements of sugarcane planting for precise seed placement.

Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
