Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a multi-functional agricultural tractor. Background Technology

[0002] Agricultural tractors include four-wheel tractor tractors, two-wheel tractor tractors, rotary tillers, rice transplanters, and rotary tillers, and are a general term for agricultural machinery.

[0003] In existing technology, agricultural tractors can be divided into two categories:

[0004] Single-function, such as having only one function, such as transplanting rice, rotary tilling, harvesting, and ridging;

[0005] Or combined functions, such as rotary tillage and fertilization, harvesting and rotary tillage;

[0006] Therefore, due to the different basic functions of agricultural tractors, farmers can only purchase agricultural machinery limited to at least two types of agricultural tractors suitable for paddy fields and dry fields, such as rice transplanters and rotary tillers, which are limited to rice transplanters and rotary tillers.

[0007] Furthermore, based on the aforementioned existing technologies, it is not difficult to find that no agricultural tractor on the market combines paddy field and dry field operations. In order to meet the needs of farmers who are not currently operating farms, i.e. farmers who use large contiguous land, such agricultural tractors that are suitable for both paddy field and dry field operations are even more necessary and can greatly alleviate their financial burden. Summary of the Invention

[0008] The purpose of this invention is to provide a multi-functional agricultural tractor to solve the above-mentioned problems.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a multi-functional agricultural tractor, including a walking assembly, on which are disposed:

[0010] A ridging component that can be detached from the advancing end, comprising at least a ridging plate assembly consisting of symmetrically arranged guide sections;

[0011] The working component includes at least a plurality of planting poles arranged in a linear array and driven to move along a predetermined trajectory, wherein the ends of the planting poles are provided with beveled blades;

[0012] The material-carrying component platform includes at least a storage bin or seedling tray for conveying the crop to be planted onto the planting pole.

[0018] Preferably, the valve assembly includes a flip plate rotatably disposed at one end of the seedling trough, and the flip plate is provided with a force-bearing plate arranged toward the inclined blade.

[0019] The inclined blade is provided with a seedling groove, and the rotating plate has two specific work positions on its moving trajectory:

[0020] At the starting position, the flipping plate cuts off the connection between the planting rod and the oblique blade.

[0021] At the termination station, the flipping plate flips over so that the force-bearing plate enters the seedling trough.

[0022] Preferably, the storage compartment faces the planting rod at an angle, and a limiting member is provided on the angle, which engages with the seedling tray. The angled blade is provided with a seedling groove, which is used to pick up seedlings from the seedling tray along the moving path of the angled blade.

[0023] Preferably, the working component includes at least two sets of mounting frames, and each set of mounting frames is equipped with at least three planting poles;

[0024] The working component also includes swing rods installed on both sides of the mounting frame, with one end of which is fixed for rotation.

[0025] Preferably, the working component further includes a rotating shaft, with Z-shaped curved arms at both ends of the rotating shaft, and rollers at the ends of the Z-shaped curved arms.

[0026] A guide rod is installed on the swing rod, and the roller is slidably disposed in the guide rail formed between the guide rod and the swing rod.

[0027] Preferably, the system also includes a walking assembly, which includes at least one set of drive wheels, with both of the shafts coupled to the drive shaft of the drive wheels via belts.

[0028] In the above technical solution, the multifunctional agricultural tractor provided by the present invention has the following beneficial effects: the working components can be combined with the storage bin or seedling tray mounted on the material loading assembly platform to perform both dryland sowing and paddy field transplanting functions. Furthermore, the detachable ridging component at the forward end of the walking assembly is mainly used for ridging, and together with the storage bin, the agricultural tractor of this application can sow on flat land or ridges.

[0029] In summary, this agricultural tractor is not only suitable for dry land and paddy fields, but also for sowing on flat land and ridges, maximizing the functionality of agricultural tractors, increasing the applicability of the device, and making the design more in line with the needs of small farmers.

Detailed Implementation

[0039] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] like Figure 1-6 As shown, a multi-functional agricultural tractor includes a walking assembly 1, on which:

[0041] The ridging component 2, which can be detached from the advancing end, includes at least a ridging plate assembly 21 composed of symmetrically arranged guide portions;

[0042] The working component 3 includes at least a plurality of planting rods 31 arranged in a linear array and driven to move along a predetermined trajectory, with a beveled blade 311 provided at the end of the planting rod 31.

[0043] The material-carrying assembly platform 4 includes at least a storage bin 41 or a seedling tray 42 for conveying the crop to be planted to the planting pole 31. Combined with... Figure 1 and Figure 2 As shown.

[0044] Specifically, in the above embodiments, the walking assembly 1 includes at least a set of drive wheels 11, a set of steering wheels 12, and a chassis 13. The drive wheels 11 are mounted on the front end of the chassis 13, while the steering wheels 12 are mounted on the rear end of the chassis 13. The chassis 13 is equipped with a steering system that drives the steering wheels 12 to steer and a braking system that performs parking on the drive wheels 11. Since the braking system and steering system are prior art, they will not be described in detail.

[0045] Furthermore, it also includes a single-piston diesel engine 100 for driving the drive wheel 11 to rotate. The transmission system between the single-piston diesel engine 100 and the drive wheel 11 can be established using a rack and pinion drive assembly, a belt drive system, or any other transmission system known to those skilled in the art.

[0046] It should be noted that the aforementioned walking component 1 can be equipped with a cab for manual driving, or it can be equipped with a wireless remote control device for remote control operation. These two operating methods are well-known technologies in existing agricultural machinery operation modes, and therefore will not be described in detail, nor are they shown in the accompanying drawings.

[0047] Furthermore, in the above embodiment, the ridging component 2 uses the ridge plate group 21 arranged in a linear array to gather the soil on the walking path of the walking component 1, thereby achieving the purpose of ridging. Moreover, it adopts a disassembly design, which can be bolted, or quick clamped, or a disassembly and assembly structure known to those skilled in the art.

[0048] In the above embodiments, the planting rod 31 moves along a predetermined trajectory. It can be driven by a cylinder to move vertically, thereby planting granular or rice seedling crops such as peanuts, peppers, and cotton in the soil. Alternatively, it can be achieved by a swing arm installed at the output end of a motor, which is welded to the planting rod 31, so that the planting rod 31 maintains an arc trajectory and plants granular or rice seedling crops in the soil during the movement. Or any driving method known to those skilled in the art is acceptable.

[0049] In the above technology, the working component 3 can be combined with the storage bin 41 or seedling tray 42 mounted on the material loading component platform 4 to perform both dryland sowing and paddy field transplanting functions. Furthermore, the detachable ridging component 2 at the forward end of the walking component 1 is mainly used for ridging, and together with the storage bin 41, the agricultural tractor of this application can sow on flat land or ridges.

[0050] In summary, this agricultural tractor is not only suitable for dry land and paddy fields, but also for sowing on flat land and ridges, maximizing the functionality of agricultural tractors, increasing the applicability of the device, and making the design more in line with the needs of small farmers.

[0051] As a further embodiment of the present invention, such as Figure 3 The two guide sections on the ridge plate assembly 21 shown are arranged in a figure-eight shape, with their wide openings facing the forward end.

[0052] Furthermore, the ridging component 2 includes a platform 22 and a screw 23. Multiple ridging plate assemblies 21 are installed in a linear array on the platform 22, and the screw 23 is threadedly assembled on the traveling assembly 1, with its end rotatably mounted on the platform 22.

[0053] Specifically, in the above embodiment, since the two guide parts are arranged in a figure-eight shape with their wide openings facing the forward end, the soil enters through the wide opening during the forward movement of the walking component 1. Under the guidance of the guide parts, the soil is scraped and gathered, and is smoothed as the chassis 13 passes by. Then, the oblique blade 311, along with the falling planting rod 31, passes through the pre-reserved notch on the chassis 13 to complete the sowing of the granular seeds.

[0054] It should be noted that the guide parts are bolted to the positioning holes arranged in a linear array on the platform 22, and the distance between the two guide parts can be changed according to actual needs. The maximum distance between the two guide parts is when any two sets of soil ridge plate groups 21 are in contact with each other.

[0055] It should be noted that during the above-mentioned ridge-making process, the soil left by every two ridge-making board groups 21 needs to be manually treated a second time, or the problem can be solved by adjusting the maximum distance between the two guide parts.

[0056] Furthermore, in the above embodiment, at least two symmetrically arranged tenon rods 25 are welded on the platform 22. The sleeve rod 24 can be installed using bolts and positioning holes. The sleeve rod 24 and the tenon rod 25 are plugged into each other. The platform 22 can be installed on the chassis 13 using screws 23. The distance between the platform 22 and the chassis 13 can be adjusted by rotating the screws 23, thereby meeting the requirements for ridging.

[0057] As another embodiment of the present invention, the storage compartment 41 is connected to the planting rod 31 via a flexible hose, and the planting rod 31 is provided with a valve assembly 5.

[0058] Specifically, in the above embodiments, the valve assembly 5 can be a distribution plate driven by a motor to rotate, the distribution plate being provided with at least a plurality of feeding chambers for receiving the granular seeds falling from the flexible hose into the planting rod 31; or it can be a hinged sealing plate that is opened and closed by a motor-driven flipping mechanism to discharge materials; or it can be a material control mechanism known to those skilled in the art.

[0059] As a further preferred embodiment provided by the present invention, such as Figure 6 As shown, the valve assembly 5 includes a flip plate 51 that is rotatably disposed at one end of the seedling trough 6, and a force-bearing plate 52 arranged on the flip plate 51 facing the inclined blade 311.

[0060] The oblique blade 311 has a seedling trough 6, and the rotating plate 51 has two specific workstations for its movement trajectory:

[0061] At the starting position, the flip plate 51 cuts off the connection between the planting rod 31 and the oblique blade 311. Figure 1 The state shown;

[0062] The work station is terminated, and the flipping plate 51 flips to the force plate 52 and enters the seedling trough 6.

[0063] Specifically, in the above embodiment, during the descent of the planting rod 31, the oblique blade 311 is implanted into the soil layer, i.e., at the termination position. Upon penetration, soil rushes in and pushes against the force plate 52. Since the force plate 52 is designed to be distributed close to the side of the seedling trough 6, its center of gravity is close to the side of the seedling trough 6 after being subjected to force. Therefore, under the influx of soil, the pushing causes the flipping plate 51 to open and close the predetermined gap for material feeding. When the oblique blade 311 disengages, the force plate 52 loses its force and returns to its original position.

[0064] The component that drives the reset can be a tension spring, and the default state of the tension spring is to cause the flip plate 51 to cut off the connection between the planting rod 31 and the oblique blade 311; or a torsion spring, and the default state of the torsion spring is to cause the flip plate 51 to cut off the connection between the planting rod 31 and the oblique blade 311; or any restoration mechanism or elastic element known to those skilled in the art.

[0065] It should be noted that the oblique blade 311, the force plate 52 and the flipping plate 51 in the above embodiments are all coated with an oil-based coating or a non-stick coating, which are common materials and will not be listed in detail. This is to ensure that the soil does not adhere to the oblique blade 311, the force plate 52 and the flipping plate 51.

[0066] As a further embodiment of the present invention, the storage compartment 41 is inclined towards the planting rod 31, and a limiting member is provided on the inclined surface. The limiting member is engaged with the seedling tray 42. The inclined blade 311 is provided with a seedling groove 6, which is used to take seedlings from the seedling tray 42 on the moving path of the inclined blade 311.

[0067] Specifically, in the above embodiment, the seedling tray 42 is engaged with the inclined surface of the storage chamber 41, and its bottom end abuts against the limiting protrusion on the chassis 13, thereby achieving limiting.

[0068] Furthermore, the seedling tray 42 includes a seedling retrieval station, so that the planting pole 31 can retrieve seedlings from the seedling retrieval station during its movement.

[0069] As another embodiment further provided by the present invention, combined with Figure 3 and Figure 4 It is known that the working component 3 includes at least two sets of mounting frames 32, and each set of mounting frames 32 is equipped with at least three planting poles 31;

[0070] The working component 3 also includes a swing arm 33 installed on both sides of the mounting bracket 32, with one end of which is fixed and rotatable.

[0071] Furthermore, the working component 3 also includes a rotating shaft 34, with Z-shaped crank arms 35 at both ends of the rotating shaft 34, and rollers 36 at the ends of the Z-shaped crank arms 35.

[0072] A guide rod 37 is installed on the swing rod 33, and the roller 36 is slidably disposed in the guide rail formed between the guide rod 37 and the swing rod 33.

[0073] Furthermore, it also includes a walking assembly 1, which includes at least a set of drive wheels 11, and two rotating shafts 34 are coupled to the drive shaft of the drive wheels 11 by belts.

[0074] Specifically, in the above embodiment, the rotating shaft 34 is connected to the drive shaft of the drive wheel 11 by a belt. Therefore, when the planting rod 31 needs to be installed, the belt is used to establish the transmission. When it is not needed, it can be directly removed.

[0075] Furthermore, in the above embodiment, the fixed point of the swing arm 33 refers to the fact that one end of it is rotatably mounted on the mounting platform on the chassis 13, while the rotating shaft 34 is mounted through the bearing seat and kept in a horizontal state.

[0076] When the drive wheel 11 is driven to rotate by the single-piston diesel engine 100, it will drive the rotating shaft 34 to rotate under the belt drive. The rotation of the rotating shaft 34 will drive the Z-shaped crank arm 35 to rotate, thereby driving the roller 36 to move in the guide rail. During the process, the mounting frame 32 is raised and then lowered, so that the planting pole 31 is inserted into the soil layer by the inclined blade 311 during the falling process, thus completing the planting operation.

[0077] Working principle:

[0078] During ridging and sowing, the drive wheel 11, driven by the single-piston diesel engine 100, rotates. As it moves, soil enters through a wide opening and, guided by the guide section, is scraped and gathered, and then smoothed as it passes over the chassis 13. Belt drive rotates the shaft 34, which in turn rotates the Z-shaped crank arm 35, causing the roller 36 to move within the guide rail. During this process, the mounting frame 32 is raised, and when it is lowered, the planting rod 31's oblique blade 311 is embedded in the soil. Upon insertion, soil rushes in and pushes against the force plate 52. Because the force plate 52 is designed to be positioned close to the seedling trough 6, its center of gravity is closer to the seedling trough 6 after being stressed. Therefore, the soil rushes in and pushes against the force plate 51, causing it to open and close a predetermined gap for material feeding. When the oblique blade 311 disengages, the force plate 52 loses its force and resets, thus completing the planting process.

[0079] When performing leveling and sowing, the ridging component 2 is removed. When the drive wheel 11 is driven to rotate by the single-piston diesel engine 100, the belt drive will cause the rotating shaft 34 to rotate. The rotation of the rotating shaft 34 will cause the Z-shaped crank arm 35 to rotate, thereby causing the roller 36 to move within the guide rail. During this process, the mounting frame 32 is raised and lowered, so that the planting rod 31, during its descent, has its oblique blade 311 embedded in the soil. When it penetrates, soil rushes in and pushes against the force plate 52. Since the force plate 52 is designed to be distributed close to the side of the seedling trough 6, its center of gravity is close to the side of the seedling trough 6 after being stressed. Therefore, with the soil rushing in, the push causes the flipping plate 51 to open and close the predetermined gap for material feeding. When the oblique blade 311 disengages, the force plate 52 loses its force and returns to its original position, thus completing the planting.

[0080] During rice transplanting, the ridging component 2 is removed, and the wheels are replaced with wheels suitable for paddy fields. The seedling tray 42 is engaged on the inclined surface of the storage bin 41, with its bottom end abutting against the limiting protrusion on the chassis 13, thus achieving limiting. When the drive wheel 11 is driven to rotate by the single-piston diesel engine 100, it will drive the rotating shaft 34 to rotate under belt transmission. The rotation of the rotating shaft 34 will drive the Z-shaped crank arm 35 to rotate, thereby driving the roller 36 to move within the guide rail. During this process, the mounting frame 32 is raised, and when the mounting frame 32 is lowered, the planting rod 31 falls, causing the inclined blade 311 to be embedded in the soil. During this process, the seedling trough 6 takes seedlings from the seedling tray 42 as the planting rod 31 moves.

[0081] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
