[0028] A plurality of continuously distributed sugarcane troughs 9 are provided on the working surface of the conveyor belt 2.

The size of the sugarcane trough 9 is larger than the diameter of a sugarcane seed.

[0029] The conveying inclination angle of the conveyor belt 2 is 50°.

[0030] The active roller 3 is a power roller, which is connected to the external walking wheel through a sprocket and a chain.

[0033] All roller sides in the roller system are provided with raised ribs.

[0034] In this embodiment, the conveyor-type sugarcane transverse planter seeder is used in conjunction with the planter and is installed on the frame of the planter. Specifically, a sugarcane collecting box 1 is installed at the front of the frame. The sugarcane collecting box 1 has a sugarcane storage space for storing sugarcane seeds. The conveyor belt 2 is installed on the frame and located behind the sugarcane collecting box 1. The front part of the conveyor belt 2 is located inside the sugarcane collecting box 1 and is tilted upward from front to back. Two reversing rollers are installed and fixed behind the sugarcane collecting box 1 and above the frame. From the first reversing roller 4 above the frame to the second reversing roller 5, the conveyor belt 2 begins to tilt upward from front to back and becomes horizontal. A third reversing roller 6 is installed and fixed on the frame at the lower right after the second reversing roller 5. From the second reversing roller 5 to the third reversing roller 6, the conveyor belt 2 begins to change from horizontal to tilted downward from front to back, and two supporting rollers are horizontally installed and fixed on the frame above the left of the third reversing roller 6. From the third reversing roller 6 to the second supporting roller 8, the conveyor belt begins to change from tilted downward from front to back to tilted upward from back to front. Between the first supporting roller 7 and the second supporting roller 8, the conveyor belt begins to change from tilted upward from back to front to horizontal. An active roller 3 is installed and fixed above the frame below the left of the first supporting roller 7 and below the sugarcane box 1. Between the first supporting roller 7 and the active roller 3, the conveyor belt begins to change from horizontal to tilted downward from back to front to form a cycle.

[0035] The following is a comparison between the specific embodiment and the existing seeding machine:

[0036] The existing seeding machine operation mechanism adopts a first-level chain for seed filling and a first-level chain for seeding. However, the actual working environment of agricultural machinery is harsh, with many influencing factors, and the actual material conversion results are poor. It is difficult for sugarcane to enter the second-level conveyor chain from the first-level conveyor chain accurately, which seriously affects the seeding machine qualification rate. Therefore, it is considered to complete the entire process of sugarcane seed filling, transportation, and seeding through a single conveyor chain. Without material conversion, the state of sugarcane during transportation is relatively stable, and the seeding machine qualification rate can be well guaranteed. Figure 5As shown, the utility model integrates the primary and secondary chains of the existing seeder into a complete conveyor belt 2. In the AD section, it still draws on mature experience, allowing the sugarcane seeds in the sugarcane collecting box 1 to be filled with seeds in this section. After filling, the sugarcane seeds are transported along the AB section to the BC section along the conveyor belt, and from the BC section to the CD section, the seeding height of the sugarcane seeds is lowered, and finally reaches point D. After reaching the seeding height, they are thrown into the pre-opened planting soil trough to complete the sowing process. The conveyor belt then rotates back to the sugarcane collecting box 1 through auxiliary means.

[0037] The ideal movement process of the seeder is that the traveling ground wheel drives the active roller 3 to rotate clockwise, and the clockwise rotation of the active roller 3 drives the conveyor belt 2 to move clockwise. The sugarcane seeds are filled into the sugarcane trough 9 of the conveyor belt 2 by themselves or by the squeezing of the sugarcane seeds against each other in the AB filling section, thus completing the filling. After entering the trough, the sugarcane seeds remain relatively stationary with the conveyor belt, and after being transported by the conveyor belt 2, they turn from the BC horizontal transport section to the CD seed throwing section, and finally throw the sugarcane seeds at point D. Then the sugarcane trough 9 rotates clockwise from point D through the supporting rollers and returns to point A of the active roller 3, completing a cycle.

[0038] Furthermore, according to the precise sowing requirement that only one cane seed can be placed in one cane trough 9, the cane trough 9 is designed to be a rectangular space with a size of 40mm×40mm×340mm. Figure 6 As shown, the conveyor belt 2 is provided with several evenly spaced sugarcane troughs along its length. These troughs are formed by two baffles melted onto the rubber conveyor belt at high temperature. The length of these troughs is distributed horizontally to ensure uniform lateral distribution of the sugarcane seeds. The horizontal length of the trough cavity is determined by the length of the sugarcane seeds, which is determined by the agronomic requirements of planting pre-cut double-bud sugarcane and the width of the planting trench dug in the ground by the sugarcane planter. The width of the trough cavity is determined by the diameter of a single sugarcane, so that each trough cavity can only hold a single sugarcane seed. The diameter of a single sugarcane seed is influenced by the variety and physical characteristics of the seed.

[0039] In previous planter seeder designs, sugarcane seed material transportation was achieved by a two-stage conveyor chain, which easily caused material conversion problems and led to a decrease in the qualified rate of the sugarcane seeder. The present utility model replaces the two-stage conveyor chain with a single conveyor belt 2, avoiding the material conversion problem. In this embodiment, the conveyor belt 2 is designed to have a circumference of 3000mm, a width of 440mm, and a thickness of 3mm. The structure is two cloths and two rubbers, the material is green PVC material, and the connection method is high-temperature toothed connection. Straight baffles are installed along the length of the conveyor belt 7. The straight baffles are evenly distributed on the conveyor belt 7 in the left and right directions. The baffle width is 340mm, the height is 40mm, the baffle thickness is 8mm to 9mm, and the spacing between the baffles is 40mm.

[0040] Furthermore, because the conveyor belt 2 is relatively short and is used for short-distance material transport, only one active roller 3 is provided. The maximum outer ring diameter of the active roller 3 is 75mm, and it is hollow to save material. A knurling process is used on the thin wall with a thickness of 3mm to increase the friction between the roller and the conveyor belt 2, preventing the conveyor belt 2 from slipping under heavy loads and during startup. The angle between the conveyor belt 2 and the active roller 3 is designed to be 160°, keeping the conveyor belt in a taut state to prevent slipping. A 10mm rib is provided on the side of the roller to prevent the conveyor belt 2 from detaching from the roller. The two support rollers are dumbbell-shaped, with a slender rod in the middle and short cylindrical ends. Raised ribs are designed on the outside to prevent the conveyor belt 7 from deviating. The reversing roller has the same design parameters as the active roller 3, and there is no printing process on the outside of the roller. To prevent the conveyor belt 2 from deviating, raised ribs are designed on both sides of the roller.

[0041] In addition, if Figure 7 As shown, considering both sugarcane storage capacity and seed filling efficiency, the sugarcane collecting box 1 is designed in an inverted triangle shape. A portion of the bottom plate is cut at the bottom of the collecting box 1 to allow the conveyor belt 2 to be located within the sugarcane storage cavity of the collecting box 1. This also reduces the gaps on the sides of the conveyor belt 7 to prevent already-entered sugarcane seeds from falling out of the sides, thus ensuring seed filling efficiency. The upper left angle of the collecting box is designed to be 50°, and the upper right angle is designed to be 60°. Based on test results, the bottom angle of the collecting box is selected to be 160°, and the angle formed by the bottom plate facing the 60° angle and the bottom plate to the left of the bottom angle is designed to be 90°. The length of the top side plate is designed to be 670mm, and the length of the bottom plate facing the 60° angle is designed to be 540mm. The width of the collecting box 1 is designed to be 360mm, the box body thickness is designed to be 2mm, and the transition radius of all bottom plate junctions is designed to be 5mm.

[0042] Furthermore, to determine the optimal inclination angle of the conveyor belt, this embodiment simplifies the model and conducts simulation tests only for the seed filling stage, establishing a simulation model consisting of the seed filling slope and the sugarcane collecting box 1. The number of sugarcane seed simulation models is set to 30. After the simulation model is established in SolidWorks, it is imported into Adams. In Adams, a sugarcane material is created and the density is set to 1100 kg / m 3, Poisson's ratio of 0.33, and Young's modulus of 1172 MPa. The designed sugarcane seed length was 300 mm, and the weight of a single seed was 300 g. The rolling friction coefficient between the sugarcane seeds and conveyor belt 2 was set to 0.152, and the rolling friction coefficient between the sugarcane seeds was set to 0.092. Constraints were then added to the simulation model, simplifying conveyor belt 2 to an inclined plane motion. A moving pair was added for conveyor belt 2 relative to the ground. The sugarcane collection box 1 was fixed to the ground, and the sugarcane seeds were suspended in the inner cavity of the collection box 1. Contacts were added to the simulation model using macro commands. The macro file was read in Adams Tools and configured for contact between sugarcane seeds, between sugarcane seeds and conveyor belt 2, and between sugarcane seeds and the collection box 1, for a total of 1250 contacts. In simulation model tests with different conveyor belt inclination angles, the conveyor belt 2 angle of 30° was too flat, resulting in sugarcane replanting under certain conditions, with sugarcane replanting in the gaps in the sugarcane trough. When the conveyor belt 2 inclination angle was 40° and the simulation lasted 26.9 seconds, the replanted sugarcane seeds followed the conveyor belt 2 upward and then fell back into the collection bin, disrupting the order of the seeds within bin 1 and causing three missed seeds. As the conveyor belt 2 inclination angle increased, reaching 50° at the end of the simulation at 42.05 seconds, 25 sugarcane seeds were neatly and orderly placed in the trough without any replanting or missed seeds, demonstrating excellent seed filling. Simulation data also performed well when the conveyor belt 2 inclination angle was 60°. However, it was clearly observed that the order of the seeds at the bottom of bin 1 was disrupted at 60°. When the conveyor belt 2 inclination angle was further tilted to 70°, the space at the bottom of bin 1 decreased, increasing the compression between the seeds. At 24.3 seconds into the simulation, the seeds became sideways, resulting in two missed seeds. Therefore, when the conveyor belt 2 inclination angle is too small, it is easy for the seeds to overlap in a single trough, causing replanting. The simulation experiment used sugarcane seeds measuring 30 mm. After the seeds were placed in the sugarcane trough, the remaining space in the trough was only 10 mm. This space was too narrow to accommodate the replanted seeds, so the conveyor belt inclination angle C should not be too small. If the conveyor belt 2 inclination angle is too large, the bottom space of the sugarcane collection box will be reduced, increasing the impact and squeezing of the sugarcane seeds, which is not conducive to stable seed filling. Therefore, a 50° conveyor belt inclination angle is preferred. The force data of the four sugarcane pieces at the top of the sugarcane collection box 1 show that the contact force between the four sugarcane pieces is mainly distributed between 5N and 15N. When the sugarcane pieces collide, the maximum contact force is 19.6N. When the contact force between the sugarcane pieces is too high, the seeds may be damaged. The use of a rubber conveyor belt reduces the contact force between the seeds to a certain extent. The maximum contact force of the four sugarcane pieces placed from the top is only 19.6N, indicating that the seed drill causes little damage to the seeds and buds during the sowing process.

[0043] In summary, the present invention has the following beneficial effects:

[0044] (1) The utility model uses a rubber conveyor belt integrated with a sugarcane trough to complete sowing, optimizes the layout of the seeder and redesigns the structure of the seeder, and realizes a stable, continuous and precise sowing process.

[0045] (2) In the present invention, the two existing seeding chains are simplified into one conveyor belt.

[0046] (3) The utility model simplifies the seeder components and reduces the manufacturing and use costs.
