Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, and in particular relates to a vacuum rotary air suction seeder. Background Technology

[0002] A pneumatic seeder is a modern agricultural machine that uses negative pressure adsorption to achieve precision seeding. The pneumatic seeder uses a fan to generate a high-speed airflow, creating a negative pressure environment that causes individual seeds to be adsorbed by suction holes on the seed metering disc. When the seed metering disc rotates to the outside of the vacuum chamber, the negative pressure disappears, and the seeds fall into the seed furrow due to their own weight or the action of a seed scraper. Compared with mechanical seeders, pneumatic seeders have significant advantages in technical performance. They can achieve single-seed sowing, reduce seed usage, lower seed costs, improve sowing precision, and significantly reduce missed sowing and double sowing rates. They are highly adaptable, meeting the sowing requirements of various crop seeds, including oblong, flat, large, medium, and small varieties, with minimal damage to the seeds, and can achieve high-speed sowing.

[0003] However, existing air-suction seeders still have problems such as high manufacturing and maintenance costs, complex structure, and increased missed seeding and reseeding rates when the ground is uneven. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a pneumatic seeder with a simple structure, low manufacturing and maintenance costs, and the ability to maintain sowing accuracy without missed or double-sowing even on uneven ground. To solve the above technical problem, the technical solution of this utility model is as follows: A vacuum rotary pneumatic seeder, comprising a power transmission system, a pneumatic sorting system, a linkage sowing system, a traveling system, and a turning system.

[0005] like Figure 1 As shown, the power transmission system consists of an engine belt, a gearbox drive shaft (not shown in the figure), a continuously variable transmission (CVT), a chain, and an engine. The engine belt connects the engine pulley to the pulley on the gearbox drive shaft. The gearbox drive shaft is horizontal, and its long axis is perpendicular to the forward travel direction of the machine. The engine is fixed near the middle of the gearbox drive shaft. There is a CVT at each end of the gearbox drive shaft. The gear on one CVT is connected to the gear on the axle of the drive wheel of the travel system via a chain. The gear on the other CVT is connected to the same-side linkage shaft gear on the linkage shaft of the following linkage system via a chain. The other linkage shaft gear on the linkage shaft is connected to the multi-fork sprocket in the following air suction sorting system via a chain. The linkage shaft gear connected to the multi-fork sprocket on the linkage shaft is on the same side as the multi-fork sprocket.

[0006] During operation, the engine generates power, and the engine pulley drives the gearbox drive shaft to rotate via the engine belt. The gearbox drive shaft then transmits the power to the continuously variable transmission (CVT). The CVT connected to the axle provides power to the propulsion system, and the CVT connected to the linkage shaft provides power to the linkage on-demand system. The linkage shaft then provides power to the air suction sorting system via a chain.

[0007] like Figure 2 As shown, the air suction sorting system includes: an electric vacuum suction pump, a rotary filter, a vacuum conduit, a vacuum conduit connector, a vacuum chamber, a multi-forked seed suction roller, a multi-forked tube ventilation port, a seed suction port, a multi-forked tube roller bearing, a multi-forked tube inner baffle, a sealing bolt, a multi-forked tube seal, and a multi-forked tube sprocket.

[0008] When sowing seeds with a particle size less than or equal to that of ginseng seeds, the electric vacuum pump is not engaged, and the air inlet of the engine is fixedly connected to the outlet of the rotary filter. When sowing seeds with a particle size greater than that of ginseng seeds, the suction nozzle of the electric vacuum pump is fixedly connected to the outlet of the rotary filter, and the engine generates electricity to power the electric vacuum pump.

[0009] The inlet of the rotary filter is tightly connected to one end of a vacuum conduit via a vacuum conduit connector. The other end of the vacuum conduit is fixedly connected to a vacuum chamber via a vacuum conduit connector. The vacuum chamber is a semi-cylindrical structure with a base and screw holes. The vacuum chamber is fixed to the seeder via the base. A vacuum conduit connector is located on the semi-cylindrical part of the vacuum chamber, and the inner diameter of the connector communicates with the interior of the vacuum chamber. The interior of the vacuum chamber is fitted or flexibly connected to a multi-forked seed-absorbing roller. The vacuum chamber is located in the middle of the multi-forked seed-absorbing roller, which is a cylindrical structure. Inside the multi-forked seed-absorbing roller, there is a long shaft parallel to the gearbox drive shaft. The long shaft has multi-forked tube internal baffles that divide the internal space of the multi-forked seed-absorbing roller into 2 to 4 chambers. Each chamber corresponds to a set of sections on the multi-forked seed-absorbing roller body for seed adsorption. The seed suction holes are evenly distributed along the generatrix that bisects the corresponding chambers. The size of the seed suction holes is designed according to the seed size to ensure stable adsorption, and the diameter of the seed suction hole is smaller than the seed diameter. At the middle of the generatrix where each group of seed suction holes is located, there is a multi-forked tube ventilation hole with a diameter larger than the seed suction hole. When the multi-forked tube ventilation hole is connected to the vacuum chamber, it is located near the highest point of its rotation. The chambers of the multi-forked seed suction roller are sealed at both ends with multi-forked tubes and fixed with sealing bolts. Multi-forked tube roller bearings with bases are fixedly installed on the long shaft outside the sealing bolts. The multi-forked tube roller bearings are fixedly installed on the seeder through the bases. On the long shaft outside the multi-forked tube roller bearing at one end of the multi-forked seed suction roller is a multi-forked tube sprocket. The multi-forked tube sprocket is connected to the gear on the same side of the linkage shaft through a chain.

[0010] During operation, air is drawn in through the engine's air intake or the suction nozzle of the electric vacuum pump, creating a vacuum negative pressure state within the rotary filter, vacuum conduit, and vacuum chamber. Simultaneously, the multi-forked pipe sprocket rotates. When the multi-forked pipe's ventilation port is connected to the vacuum chamber, the seed suction hole is located near its highest point, where a vacuum negative pressure state exists, providing adsorption force to attract seeds. When the multi-forked pipe sprocket rotates to the point where the multi-forked pipe's ventilation port is no longer connected to the vacuum chamber, the seed suction hole is located near its lowest point, and there is no adsorption force. The seeds fall naturally into the conduit directly below the seed suction hole due to gravity. The other end of the conduit is connected to one end of the seeding duckbill assembly of the seeding system described below.

[0011] like Figure 3 As shown, the linkage seeding system includes a linkage shaft, linkage bearing, linkage shaft gear, seeding duckbill assembly, steering rocker arm, seeding lifting linkage arm A, and seeding lifting linkage arm B.

[0012] The linkage shaft is a long shaft parallel to the multi-forked seed suction drum. Each end of the linkage shaft has a linkage shaft gear. One linkage shaft gear is connected to a gear on the continuously variable transmission (CVT) on the same side via a chain, and the other linkage shaft gear is connected to a multi-forked tube sprocket on the multi-forked seed suction drum via a chain. Each linkage shaft gear has a linkage bearing inside, which is fixed to the seeder via its own base. One end of a steering rocker arm is fixedly connected to the outside of each linkage shaft gear. The steering rocker arm rotates with the rotation of the linkage shaft. The other end of the steering rocker arm is fixedly connected to one end of another steering rocker arm via a connecting shaft. One end of seed-feeding lifting linkage arm B is fixedly mounted on the other end of the other steering rocker arm. The other end of seed-feeding lifting linkage arm B is fixedly connected to the seedering duckbill assembly. The seedering duckbill assembly consists of 15 to 30 identical seeders arranged side-by-side. One end of seed-feeding lifting linkage arm A is fixedly connected to each of the two connecting shafts. The other end of seed-feeding lifting linkage arm A is fixedly mounted on the seedering duckbill assembly.

[0013] During operation, the linkage shaft rotates, which in turn drives the seed-feeding lifting linkage arm A and seed-feeding lifting linkage arm B to move the seed-feeding duckbill assembly up and down, thus completing the seed-feeding.

[0014] The travel system includes axles and wheels, and it ensures the movement of the video player.

[0015] The turning system is used for turning around the on-demand machine.

[0016] Through the above design scheme, this utility model can bring the following beneficial effects:

[0017] 1. It has a simple structure and low manufacturing and maintenance costs.

[0018] 2. The size of the grain suction pores is matched with the seed size. By adjusting the size of the suction pores and the negative pressure intensity, the phenomenon of multiple grains sticking together is greatly reduced while ensuring the stability of seed adsorption. This reduces the amount of seed used, lowers seed costs, improves sowing precision, and significantly reduces the rate of missed sowing and re-sowing on uneven ground. Attached Figure Description

The multi-forked tube inner partitions (14) divide the interior space of the multi-forked seed suction roller (10) into 2 to 4 chambers. The cylindrical part of the multi-forked seed suction roller (10) corresponding to each chamber is separated. There is a set of seed suction holes (12) for adsorbing seeds. The seed suction holes (12) are evenly distributed along the generatrix that bisects the corresponding chambers. The size of the seed suction holes (12) is designed according to the seed size to ensure stable adsorption. The diameter of the seed suction holes (12) is smaller than the seed diameter. At the middle position of the generatrix where each set of seed suction holes (12) is located, there is a multi-forked vent (11) with a diameter larger than the seed suction hole (12). When the multi-forked vent (11) is connected to the vacuum chamber (9), the multi-forked vent (11) is located near the highest point of its rotation. At both ends of the multi-forked seed suction roller (10) Do not use a multi-forked pipe seal (16) to seal the chamber of the multi-forked seed suction roller (10). Fix the multi-forked pipe seal (16) with a sealing bolt (15). Fix the multi-forked pipe roller bearing (13) with a base on the long shaft outside the sealing bolt (15). The multi-forked pipe roller bearing (13) is fixedly installed on the seeder through the base. On the long shaft outside the multi-forked pipe roller bearing (13) at one end of the multi-forked seed suction roller (10) is a multi-forked pipe sprocket (17). The multi-forked pipe sprocket (17) is connected to the same side linkage shaft gear (20) on the linkage shaft (18) through the chain (4).
