Description

Technical Field

[0001] The present invention relates to the field of mechanized tillage boats, and in particular to a high-efficiency improved four-wheel drive mechanized tillage boat. Background Art

[0002] The tractor-till boat can adapt to the requirements of different paddy field operations. Deep, muddy paddy fields have poor soil bearing capacity, and using wheeled tractors would cause the wheels to sink, reducing work efficiency. The tractor-till boat's drive wheel blades penetrate the soil to propel the boat forward, addressing some of the drawbacks of using tractors in paddy field operations.

[0003] In order to improve the power of the mechanized tiller and to enable the mechanized tiller to operate smoothly in complex environments, the existing four-wheel drive mechanized tiller is designed.

[0004] The existing high-efficiency improved four-wheel drive tiller has the following problems during operation:

[0005] Existing mechanized tillers need to perform a variety of different tasks, including mowing paddy fields, harvesting crops, and sowing seeds. However, when performing different tasks, the various components of the existing mechanized tillers cannot be switched according to the different tasks to improve work efficiency.

[0006] In the process of performing different tasks, the existing mechanized tiller boats are unable to adjust the water flow under the hull as needed to adapt to tasks such as harvesting crops, mowing grass or sowing, and to improve the effect of each task. Summary of the Invention

[0007] The purpose of the present invention is to provide a high-efficiency improved four-wheel drive mechanized tiller boat, which can improve work efficiency and work effect.

[0008] The present invention is a high-efficiency improved four-wheel drive tiller boat, comprising a hull, a driving assembly, a cutting assembly, a power assembly, an adjusting assembly and a spoiler assembly;

[0009] The driving assembly and the power assembly are both arranged inside the hull, the cutting assembly, the adjusting assembly and the spoiler assembly are all arranged below the hull, the driving assembly is connected to the cutting assembly, and the power assembly is connected to the adjusting assembly and the spoiler assembly.

[0010] The drive assembly includes a drive motor, a drive shaft, a first transmission system and a running wheel. The drive motor is arranged inside the hull. One end of the drive shaft is connected to the output end of the drive motor, and the other end of the drive shaft is connected to the input end of the first transmission system. The first transmission system output ends are provided with four, and each of the first transmission system output ends is connected to a running wheel.

[0011] Among them, the first transmission system can change the transmission direction, and the rotation of the drive motor drives the four walking wheels to rotate.

[0012] The cutting assembly includes a second transmission system, a driving pulley, a driven pulley, a transmission belt, a transmission shaft and a cutting knife, wherein the second transmission system is arranged on the driving shaft, and the input end of the second transmission system is connected to the driving shaft, the driving pulley is connected to the output end of the second transmission system, a plurality of the driven pulleys and the driving pulleys are driven by a plurality of transmission belts, one end of the transmission shaft is connected to the driven pulley, and the other end of the transmission shaft is connected to the cutting knife;

[0013] The second transmission system can change the transmission direction, so that the rotation of the drive shaft drives the active pulley to rotate.

[0014] The power assembly includes a power motor, a pulley system, a driving gear and a driven gear. The power motor is arranged inside the hull. The input end of the pulley system is connected to the output end of the power motor. The two driving gears are connected to the input ends of the two pulley systems. The two driven gears are respectively engaged with the two driving gears.

[0015] The pulley system is provided with two pulleys and a belt, which can drive the two driving gears to rotate.

[0016] The adjustment assembly includes a connecting shaft, an adjuster and a roller. One end of the connecting shaft is connected to the bottom of the driven gear, and the other end of the connecting shaft is connected to the adjuster. The adjuster is divided into two sections. One section of the adjuster is straight, and the other section of the adjuster is set at a 120° angle to the first section. Several rollers are movably arranged on one side of the adjuster.

[0017] The spoiler assembly includes a ball screw, a moving block, a fixed plate and a spoiler. One end of the ball screw is connected to the bottom of the driving gear. The moving block is movably arranged on the ball screw. The fixed plate is connected to the moving block. Several spoilers are arranged on one side of the fixed plate.

[0018] A plurality of bevel gears are provided in the first transmission system and the second transmission system for meshing, and the first transmission system is provided with a plurality of transmission rods connected with a plurality of travel wheels.

[0019] The rollers are arranged in a straight line, and the distances between the rollers are the same.

[0020] There are gaps between the spoilers, and the spoilers are arranged horizontally and vertically at intervals.

[0021] The present invention has the following beneficial effects:

[0022] The present invention sets an adjustment component in an initial position during weed cutting, with a straight section of the adjuster parallel to the hull and close to the cutting blade, and the other section inclined toward both sides of the hull. The cut weeds first pass through the straight section and contact the roller, which guides the weeds to the inclined section and then to both sides of the hull, thereby reducing interference from the weeds and allowing the weeds to be dispersed in the paddy field to provide fertility.

[0023] The present invention starts a power motor during the process of cutting crops. The power motor drives the pulley system to rotate. The pulley system drives two driving gears to rotate, and respectively drives two driven gears to rotate. Then, the regulator is driven to rotate through the connecting shaft, so that the straight section of the regulator forms a certain angle with the hull, and the inclined section becomes parallel to the hull. The cut crops contact the roller, and the roller tilts the section to gather the crops in the middle, thereby improving the harvesting efficiency of the crops.

[0024] In the process of cutting weeds, the present invention places the spoiler assembly in the initial position, and the fixing plate and the spoiler are relatively close to the hull, so as to greatly disturb the water flow near the water surface. The harvested weeds can be transported to all directions of the hull through the waves of the water, which can reduce the subsequent processing of the weeds and improve the extensive utilization of the weeds.

[0025] In the process of cutting crops, the present invention drives the pulley system to rotate by a power motor, and the pulley system drives two driving gears to rotate, and the driving gear drives the ball screw to rotate. The self-rotation of the ball screw can drive the moving block to move downward, and then move the fixed plate and the spoiler to the underwater far away from the hull. At this time, the spoiler is located below the cut crops, and its disturbance of the water flow can push the crops above to the water surface, and can also reduce the influence of the water flow on the movement of the mechanized tiller.

[0026] The present invention improves work efficiency by enabling the adjustment component and the spoiler component to be switched according to different tasks when the tiller boat performs different tasks.

[0027] The present invention drives the driving motor to rotate the driving shaft during the driving walking process, and then the second transmission system drives the driving pulley to rotate through the rotation of the driving shaft, and the active pulley drives multiple driven pulleys to rotate through multiple transmission belts, and the multiple driven pulleys drive the transmission shaft to rotate, and the transmission shaft drives the cutting knife to rotate, and the cutting knife cuts the crops or weeds below. The walking and cutting of the mechanized tiller can be linked, the synchronization of harvesting and movement can be improved, and the time for harvesting preparation can be reduced, thereby improving the harvesting efficiency.

[0028] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The two driven gears 1404 are respectively engaged with the two driving gears 1403.

[0050] The pulley system 1402 is provided with two pulleys and a belt, which can drive the two driving gears 1403 to rotate.

[0051] Adjustment assembly 150 includes a connecting shaft 1501, an adjuster 1502, and rollers 1503. One end of connecting shaft 1501 is connected to the bottom of driven gear 1404, and the other end of connecting shaft 1501 is connected to adjuster 1502. Adjuster 1502 is divided into two sections. One section of adjuster 1502 is straight, and the other section is arranged at a 120° angle to the first section. A plurality of rollers 1503 are movably arranged on one side of adjuster 1502.

[0052] During operation, when cutting weeds, the adjustment assembly 150 is in the initial position. The straight section of the adjuster 1502 is parallel to the hull 110 and close to the cutting blade 1306, while the other section is inclined toward both sides of the hull 110. The cut weeds first pass through the straight section and contact the roller 1503.

[0053] During the crop cutting process, the power motor 1401 is started, and the power motor 1401 drives the pulley system 1402 to rotate. The pulley system 1402 drives the two driving gears 1403 to rotate, and respectively drives the two driven gears 1404 to rotate. Then, the regulator 1502 is driven to rotate through the connecting shaft 1501, so that the straight section of the regulator 1502 forms a certain angle with the hull 110, and the inclined section becomes parallel to the hull 110. The cut crops contact the roller 1503, and the roller 1503 tilts the section to gather the crops in the middle, thereby improving the efficiency of crop harvesting.

The harvested weeds can be transported to all directions of the hull 110 through the waves of the water, which can reduce the subsequent processing of the weeds and improve the extensive utilization of the weeds.

[0057] Moreover, during the process of cutting crops, the power motor 1401 drives the pulley system 1402 to rotate, the pulley system 1402 drives the two driving gears 1403 to rotate, and the driving gear 1403 drives the ball screw 1601 to rotate. The self-rotation of the ball screw 1601 can drive the moving block 1602 to move downward, and then move the fixed plate 1603 and the spoiler 1604 to the underwater farther away from the hull 110. At this time, the spoiler 1604 is located below the crops being cut, and its disturbance of the water flow can push the crops above to the surface of the water, and can also reduce the impact of the water flow on the movement of the mechanized farming boat.

[0060] If there are gaps between the flow-interfering plates 1604, and if the flow-interfering plates 1604 are arranged horizontally and vertically at intervals;

[0061] The working steps of the high-efficiency improved four-wheel drive tiller boat of the present invention are as follows:

[0062] Drive travel:

[0063] The drive motor 1201 is started, and the drive motor 1201 drives the drive shaft 1202 to rotate. The first transmission system 1203 drives the rotation of the drive shaft 1202 in all directions, and then drives the various running wheels 1204 to rotate. The various running wheels 1204 move synchronously to drive the hull 110 to move;

[0064] Cutting:

[0065] During the driving process, the driving motor 1201 drives the driving shaft 1202 to rotate, and then the second transmission system 1301 uses the rotation of the driving shaft 1202 to drive the active pulley 1302 to rotate, and the active pulley 1302 drives the multiple driven pulleys 1303 to rotate through multiple transmission belts 1304, and the multiple driven pulleys 1303 drive the transmission shaft 1305 to rotate, and the transmission shaft 1305 drives the cutting knife 1306 to rotate, and the cutting knife 1306 cuts the crops or weeds below;

[0066] Assistance:

[0067] During weed cutting, the adjustment assembly 150 is in the initial position, with the straight section of the adjuster 1502 parallel to the hull 110 and close to the cutting blade 1306, while the other section is inclined toward the sides of the hull 110. The cut weeds first pass through the straight section and contact the roller 1503. The roller 1503 guides the weeds toward the inclined section and then toward the sides of the hull 110.

[0068] During the crop cutting process, the power motor 1401 is started, which drives the pulley system 1402 to rotate. The pulley system 1402 drives the two driving gears 1403 to rotate, and respectively drives the two driven gears 1404 to rotate. Then, the regulator 1502 is driven to rotate via the connecting shaft 1501, so that the straight section of the regulator 1502 forms a certain angle with the hull 110, and the inclined section becomes parallel to the hull 110. The cut crops contact the roller 1503, and the roller 1503 tilts the section, gathering the crops in the middle.

[0069] Moreover, in the process of sowing and fertilizing, just like cutting crops, it can gather seeds and fertilizers, prevent them from being scattered, and concentrate them in the center of the ridge.

[0070] Spoiler:

[0071] During the weed cutting process, the spoiler assembly 160 is in the initial position, the fixing plate 1603 and the spoiler 1604 are relatively close to the hull 110, and the water flow near the water surface is greatly disturbed, so that the harvested weeds can be transported to all directions of the hull 110 through the waves of the water.

[0072] During the crop cutting process, the power motor 1401 drives the pulley system 1402 to rotate, the pulley system 1402 drives the two driving gears 1403 to rotate, and the driving gear 1403 drives the ball screw 1601 to rotate. The self-rotation of the ball screw 1601 can drive the moving block 1602 to move downward, and then move the fixed plate 1603 and the spoiler 1604 to the underwater position farther away from the hull 110. At this time, the spoiler 1604 is located below the crops being cut. The disturbance of the water flow can push the crops above to the surface of the water, and can also reduce the impact of the water flow on the movement of the mechanized tiller boat.

[0073] Moreover, during the process of sowing and fertilizing, just like cutting crops, seeds and fertilizers can be better transported to the ridges below the water surface.
