Description

Technical Field

[0001] The utility model relates to the technical field of intelligent agricultural machinery, and more specifically to an unmanned mountain driving oil-electric hybrid convertible crawler modular rotary tiller. Background Art

[0002] A rotary tiller is a tilling machine that is used with a tractor to complete ploughing and harrowing operations. It has been widely used because of its strong soil crushing ability and flat surface after plowing. It can also cut up the root stubble buried below the surface, which is convenient for the seed drill to operate and provide a good seed bed for later sowing. According to the configuration of the rotary tiller shaft, it is divided into three types: horizontal shaft type, vertical shaft type and inclined shaft type. Correct use and adjustment of the rotary tiller is very important to maintain its good technical condition and ensure the quality of tillage. The rotary tiller has the functions of breaking the plow bottom layer, restoring the soil tillage layer structure, improving the soil's ability to store water and retain moisture, eliminating some weeds, reducing pests and diseases, leveling the surface, and improving the standard of agricultural mechanization operations.

[0003] Hilly and mountainous areas account for more than 2 / 3 of my country's total land area. The total grain production in hilly and mountainous areas accounts for 40% of the country's total output. The traditional farming methods in hilly and mountainous areas have low production efficiency and are difficult to improve the agricultural economy. Mechanized planting technology in hilly and mountainous areas has gradually become popular, which has led to the development of crawler rotary tillers.

[0004] However, the traditional rotary tiller is complicated to operate. For operators, the learning cost is high, the operation is complicated, and the work intensity is high. In addition, for the complex and changeable environment of mountainous and hilly areas, flat crawler rotary tillers are suitable for flat cultivated land. Compared with triangular crawlers, they are not effective for irregular or rugged terrain, or even cannot be used. Compared with other types of rotary tillers, triangular crawler rotary tillers have a wider range of applications, but compared with flat crawler rotary tillers, triangular crawler rotary tillers are not suitable for deep mud fields, swamps and other terrains with high water content, which leads to farmers buying rotary tillers with different crawlers according to different terrains, which increases costs. In addition, the fixing structure between the rotary tillage mechanism and the chassis of traditional rotary tillers is relatively complex, the maintenance time is long, and the functionality is single; traditional rotary tillers are mainly driven by engines, which are noisy, energy-intensive, and cause serious environmental pollution.

[0005] Therefore, how to provide a variable crawler rotary tiller that can adapt to both flat farmland and complex adjacent environments such as mountains and hills, and can make corresponding adjustments according to different terrains, thereby reducing consumer costs and improving the passability of the rotary tiller, is a problem that technical personnel in this field urgently need to solve.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] like Figure 1 , 2 As shown in Figure 5, the embodiment of the utility model discloses an unmanned mountain oil-electric hybrid convertible crawler modular rotary tiller, which improves the passability of the rotary tiller by changing the posture of the crawler, and can travel on flat fields and rugged mountains and hills. The working mechanism is modularized, which reduces the maintenance and disassembly time and improves the work efficiency, including:

[0040] A chassis 1, a chassis control mechanism 2 is fixed to the top surface of the front end of the chassis 1 in the direction of travel, a driving mechanism 3 is fixed to the top surface of the rear end, and a chassis motor 6 is fixed to the bottom surface of the middle part and is in communication connection with the chassis control mechanism 2;

[0041] A rotary tillage mechanism 5, which is arranged at the rear of the chassis 1 and is transmission-connected to the driving mechanism 3;

[0042] Track mechanism 7, the number of track mechanism 7 is two sets and they are symmetrically arranged on the left and right sides of the bottom surface of chassis 1 and are drivingly connected to chassis motor 6;

[0043] Support wheel 9, support wheel 9 is rotatably abutted against the inner wall of the crawler track of crawler mechanism 7;

[0044] The hydraulic control mechanism 8 is fixed to the bottom surface of the chassis 1 and its driving end is fixed to the side wall of the support wheel 9 to adjust the position of the support wheel 9 in the crawler track of the crawler mechanism 7.

[0045] In order to further optimize the above technical solution, the track mechanism 7 includes a bracket 71, a track 74, a driving wheel 72 and an auxiliary wheel 73. The track 74 is annular and is sleeved on the outer periphery of the bracket 71. The driving wheel 72 is fixed to the output shaft of the chassis motor 6. The driving wheel 72 is arranged at the top middle part of the bracket 71 and is rotatably abutted against the inner wall of the track 74. There are multiple auxiliary wheels 73 and they are rotatably abutted against the inner wall of the track 74 at the bottom end of the bracket 71. There are two supporting wheels 9 in each group of track mechanisms 7 and they are symmetrical on both sides of the driving wheel 72.

[0046] See also Figure 6The tracks are supported on both sides of the rotary tiller by brackets. The chassis motor provides power for the rotation of the tracks. The rotation of the chassis motor drives the rotation of the driving wheel to realize the rotation of the tracks. The auxiliary wheel moves as the driving wheel rotates. The driving wheel and the auxiliary wheel work together to realize the rotation of the tracks. The support wheels are supported at both ends of the tracks.

[0047] In this embodiment, the hydraulic control mechanism 8 includes a hydraulic controller 81, a connecting rod 82, a cross bar 83, and a control rod 84. The hydraulic controller 81 is fixed on the bottom surface of the chassis 1 and is communicated with the chassis control mechanism 2; there are two connecting rods 82 and they are symmetrical on the left and right sides of the chassis 1. One end of the two connecting rods 82 is fixedly connected to the output shafts at both ends of the hydraulic controller 81 respectively. The cross bar 83 is arranged perpendicular to the travel direction of the chassis 1 and is passed from the bottom of the chassis 1 between the two crawlers 74 located on both sides thereof.

[0048] like Figure 1 and 7 As shown, the hydraulic control mechanism controls the positions of the two supporting wheels on the left and right sides of the chassis respectively, and the second control rod can fix the position of the supporting wheel and achieve local rotation coordination with the first control rod. When encountering a rugged mountain road during flat field operations and needing to change the track posture, the connecting rod, the cross bar and the first control rod are lifted upward, which can change the flat track into a triangular track, thereby realizing driving on rugged mountainous and hilly terrain conditions and improving its passability; similarly, when the track is a triangular track, when encountering a paddy field or a deep mud field, the connecting rod, the cross bar and the first control rod slide downward to change the track into a flat track, thereby improving the passability of the rotary tiller in paddy fields and deep mud fields.

[0049] In order to further optimize the above technical solution, there are two sets of hydraulic control mechanisms 8, which are respectively located at the front and rear ends of the crawler 74. The two sets of hydraulic control mechanisms control the positions of the four support wheels on the front and rear sides of the chassis, and adjust the posture of the crawler by changing the positions of the support wheels to improve its passability.

[0050] In order to further optimize the above technical solution, protect the rotary tiller control system from being eroded by rainwater and prevent the occurrence of safety accidents, it also includes a machine cover 13, two of which are detachably connected to the top surface of the chassis 1 and respectively engage with the chassis control mechanism 2 and the drive mechanism 3.

[0051] In some other specific embodiments, a satellite positioning navigation system 131 is fixed to the top surface of the cover 13 of the drive mechanism 3. The satellite positioning navigation system and the remote controller can realize the autonomous operation of the rotary tiller, and the rotary tiller can enter the unmanned working mode, reducing the labor intensity of the operator.

[0052] In order to further optimize the above technical solution, a seat 10 is fixed on the top surface of the chassis 1 and located between the chassis control mechanism 2 and the driving mechanism 3, a sunshade frame 13 is provided above the seat 10, and the legs of the sunshade frame 13 are fixed to the two side walls opposite to the cover 13; a button operating mechanism 11 is fixed to the right front of the seat 10, and the button operating mechanism 11 is respectively communicated with the chassis control mechanism 2 and the driving mechanism 3.

[0053] When manual driving is adopted, the rotary tiller can be controlled by a key operating mechanism.

[0054] See attached Figure 8 The key operating mechanism 11 includes a base and a rocker, the rocker is arranged on the top surface of the base, and is provided with a rotary tiller lowering key 111, a rotary tiller raising key 112, a pneumatic quick release control key 113, and a light switch key 114; an engine start key 115 and a chassis motor start key 116 are arranged at the rear of the base; a crawler change key 117 is arranged on the left side of the base, and when the rotary tiller is in the manual driving state, the operator can control the rotary tilling mechanism by pressing the key, and control the hydraulic control mechanism to start by the crawler change key to realize the change of crawler posture; specifically,

[0055] When the rotary tiller is working in hilly and mountainous areas, the operator can choose autonomous driving, remote control operation or unmanned operation through a satellite positioning and navigation system. During autonomous driving, when the rotary tiller is on a flat track and encounters a rugged mountain road during driving, press the track change key on the rocker or the track change key on the remote control, and the signal of the rocker is transmitted to the chassis control mechanism to operate the hydraulic controller, driving the connecting rod, the cross bar, and the first control rod to lift upward, thereby prompting the support wheel to gather toward the driving wheel, so that the flat track is transformed into a triangular track, thereby improving the off-road performance of the rotary tiller; similarly, when the working environment is a triangular track, when encountering a paddy field or a deep mud field, press the track change key on the rocker or the track change key on the remote control, and the signal of the rocker is transmitted to the chassis control mechanism to operate the hydraulic controller, driving the connecting rod, the cross bar, and the first control rod to fall downward, prompting the support wheel to move away from the driving wheel, so that the triangular track is converted into a flat track, thereby improving the passability of the rotary tiller in paddy fields and deep mud fields.

[0056] The driving method is to move the joystick forward, backward, left, and right to transmit the motion signal to the chassis control mechanism so that the chassis motor drives the active wheel to drive the auxiliary wheel to rotate to realize the crawler to move in the corresponding direction;

[0057] When the height of the rotary tillage mechanism needs to be adjusted, the rotary tiller up key 112 and the rotary tiller down key 111 on the rocker are pressed to transmit signals to the rotary tillage mechanism control assembly 4, so that the hydraulic motor 34 is activated to drive the rotary tillage mechanism 5 to rise or fall to the specified height.

[0058] In order to further optimize the above technical solution, the rotary tillage mechanism 5 includes a frame 51, a reducer 52 and a quick-release transmission 53. A rotary tiller is rotatably connected inside the frame 51. The reducer 52 is fixed on the top surface of the frame 51 and can control the rotation of the rotary tiller. The reducer 52 is pin-connected to the driving cylinder of the driving mechanism 3; the quick-release transmission 53 is vertically fixed on one side of the reducer 52, one end of the driving shaft of the quick-release transmission 53 is rotatably connected to the driving shaft of the reducer 52, and the other end is connected to the transmission part of the driving mechanism 3 through a belt drive.

[0059] In order to further optimize the above technical solution, the driving mechanism 3 includes an engine 31, a transmission main wheel 32, a hydraulic motor 34, and a hydraulic cylinder 35. The engine 31 is fixed to the top surface of the chassis 1, the transmission main wheel 32 is fixed to the output shaft of the engine 31, and the end of the driving shaft of the quick-release transmission 53 away from the reducer 52 is detachably connected to the transmission secondary wheel 54. The transmission main wheel 32 and the transmission secondary wheel 54 are connected by a belt 33.

[0060] The hydraulic motor 34 is fixed on the top surface of the chassis 1 and is located behind the engine 31 . The hydraulic cylinder 35 is fixed on the top surface of the chassis 1 through a bracket and its cylinder body is transmission-connected to the hydraulic motor 34 . The piston rod of the hydraulic cylinder 35 is pin-connected to the reducer 52 through a connecting piece 36 .

[0061] like Figure 3 and 4 As shown, the reducer of the rotary tillage mechanism is pin-connected with the piston rod of the hydraulic cylinder through a connecting piece and a pin shaft, a quick-release controller is fixed to the side wall of the reducer, and a transmission secondary wheel is provided at one end of the quick-release controller away from the reducer. The transmission secondary wheel and the transmission main wheel are driven by a belt. After the engine is started, the transmission main wheel drives the transmission secondary wheel to rotate, thereby realizing the rotary tillage operation;

[0062] In order to further optimize the above technical solution, an air pump 37 is also included. The air pump 37 is fixed on the top surface of the chassis 1 and is located on the right side of the engine 31. The air pump 37 is pneumatically connected to the quick-release transmission 53 through an air pipe 38.

[0063] When the rotary tillage mechanism is damaged or other agricultural mechanisms are installed, press the pneumatic quick-release control key on the rocker or the quick-release button on the remote control to make the air pump spray air to the air-spray quick-release controller, release the matching between the transmission sub-wheel and the quick-release controller, and pull out the pin shaft through the hydraulic cylinder piston rod and the top of the reducer to complete the removal of the rotary tillage mechanism. During installation, the hydraulic cylinder piston rod and connecting parts are pinned to the top of the working device of other agricultural mechanisms, align the quick-release controller with the transmission sub-wheel, press the pneumatic quick-release control key to make the air pump suck air to the quick-release controller, and make the transmission sub-wheel match the quick-release controller.

[0064] In some other specific embodiments, a battery is fixed under the frame of the chassis control mechanism, and the rotary tillage mechanism can use the battery as a power source and adopt an oil-electric hybrid drive mode to reduce the consumption of oil resources and achieve energy conservation and emission reduction.
