Description

Technical Field

[0001] The invention relates to the field of loader control, in particular to a pedal adjustment system for a small loader. Background Art

[0002] A loader is a type of earthwork machine widely used in construction projects such as highways, railways, buildings, hydropower stations, ports, and mines. It is primarily used for loading bulk materials such as soil, sand, lime, and coal, and can also perform light excavation of ore and hard soil. The pedal is an essential component of loader operation, and operating the pedal and designing pedal control commands can improve loader efficiency.

[0003] The existing Chinese patent with publication number CN111856976B discloses a control system for the hydraulic motor of an electric loader, including a first displacement switch, a second displacement switch, a third displacement switch, a fourth displacement switch, an accelerator pedal, a vehicle speed sensor, and a controller. The input end of the controller is respectively connected to the first displacement switch, the second displacement switch, the third displacement switch, the fourth displacement switch, the vehicle speed sensor, and the accelerator pedal, and its output end is used to connect to the control end of the hydraulic motor: the controller calculates the control signal of the hydraulic motor based on the output signals of the first displacement switch, the second displacement switch, the third displacement switch, the fourth displacement switch, the vehicle speed sensor, and the accelerator pedal, and outputs it to the hydraulic motor to realize control of the hydraulic motor. This invention can solve the problems of the hydraulic motor of existing pure electric loaders that cannot be accurately controlled, energy saving, and comfort are poor;

[0004] However, the control system of the hydraulic motor of the electric loader still has the following defects:

[0005] 1. The work of the loader is to shovel bulk materials such as soil, sand, lime, and coal. However, bulk materials such as soil, sand, lime, and coal are prone to raise dust when shoveling. The dust not only affects the driver's vision, but also affects the accuracy of the driver's operation and increases the cleaning pressure of the loader.

[0006] 2. In addition, the loader cannot issue different operating instructions for bulk materials such as soil, sand, gravel, lime, and coal according to the actual environmental conditions when working. In actual use, different instructions need to be issued for bulk materials in response to different needs. When it is necessary to clean bulk materials such as soil, sand, gravel, lime, and coal, it is necessary to push the bulk materials to the far end and push the bulk materials into the preset pit for burial. When it is necessary to concentrate the processing of bulk materials, it is necessary to move the operating instructions inward to gather the bulk materials in one place. Summary of the Invention

[0030] The present invention provides a pedal adjustment system for a small loader through improvement, which has the following improvements and advantages compared with the prior art:

[0031] Firstly, by operating the pedal adjustment system, the loader is given instructions to control its operation. Further operation of the pedal causes the spray joint and the pressure joint to assist the loader in its operation, thereby removing dust from the loader and further reducing the dust raised when shoveling bulk materials such as soil, sand, lime and coal. Dust not only affects the driver's vision, but also affects the driver's operating accuracy, and increases the cleaning pressure of the loader.

[0032] Specifically, the first double-headed motor drives the first transmission roller to rotate, and the first transmission roller drives the transmission spur gear to rotate. The first transmission roller is close to the water tank turntable that passes through one side of the transmission spur gear. When the user steps on the L-shaped pedal, the limit plate's restriction on the L-shaped hook plate falls off, and the first metal pressure plate pushes the L-shaped hook plate toward the direction of the transmission spur gear through its own elasticity, so that the L-shaped hook plate hooks the transmission spur gear. When the L-shaped hook plate and the transmission spur gear are stuck, the water tank turntable is driven to rotate by the transmission spur gear, and then after the L-shaped hook plate makes a circle and reaches the L-shaped pedal, if the user releases the foot pedal, the L-pedal is moved by the elastic second metal pressure plate. The pressure plate is pushed to reset, and the L-shaped hook plate is stuck by the limit plate again. At the same time, the water tank turntable is stuck and fixed. If the user still steps on the pedal, the limit plate will not limit the position of the L-shaped hook plate. At this time, the water tank turntable still rotates with the transmission spur gear. The spray joint installed on one side of the water tank turntable can spray spray to remove dust, and the elastic element pushes the flip part to rotate around the Y-shaped support part, which can drive the dust removal sprayer to adjust the angle, so that the spray direction is outward. At this time, the dust removal sprayer drives the pressurized joint to spray water to further remove dust. In addition, the dust removal sprayer is provided with multiple groups of ring-shaped distribution around the water tank turntable, which is convenient for multi-directional spraying of dust removal spray.

[0033] Secondly, by manually adjusting the steering pulley, the loader shovel can be controlled to push and sweep bulk materials such as soil, sand, lime and coal toward the front and move them inward, thereby achieving the effect of assisting the loader in its operation through the pedal adjustment structure; when bulk materials such as soil, sand, lime and coal need to be cleaned, the loader shovel is controlled to push the bulk materials toward the far end and push the bulk materials into a preset pit for burial; when bulk materials need to be processed in a centralized manner, the loader shovel is controlled to reverse and move inward to gather the bulk materials in one place;

[0034] Specifically, the second double-headed motor drives the second transmission roller to rotate, and the cross connecting piece supports the second transmission roller at the top of the aluminum alloy frame. The second transmission roller drives the transmission inclined plate to rotate, and the transmission inclined plate drives the first transmission rod to rotate. The first transmission rod drives the L-shaped transmission plate to move around the center line of the second transmission roller. Through multiple sets of parts, the arc-shaped transmission claw contacts the herringbone transmission gear during movement and drives the herringbone transmission gear to move, thereby achieving the purpose of driving the herringbone transmission gear to rotate through the arc-shaped transmission claw and the herringbone meshing teeth;

[0035] In addition, the structure can be further controlled by operating the steering pulley through the pedal. Specifically, by rotating the steering pulley, the steering pulley drives the first transmission gear to rotate, and the first transmission gear drives the transmission rack to move through meshing transmission, and the transmission rack drives the second transmission gear to rotate. The second transmission gear drives the shielding side plate to flip around the center line of the second transmission gear. Only the arc-shaped transmission claw on one side can move the herringbone transmission gear. The function of the shielding side plate is to prevent the herringbone meshing teeth from moving the herringbone transmission gear. When the herringbone meshing teeth on one side contact the herringbone transmission gear, the herringbone transmission gear will rotate in the direction of the herringbone meshing teeth on the side it contacts. The rotation direction of the herringbone transmission gear can be adjusted through this structure. The herringbone transmission gear can further drive the loader shovel to flip forward and reverse, and can control the loader shovel to push and sweep toward the front end and to shift inward, thereby achieving the effect of assisting the loader to work through the pedal adjustment structure when the loader is working. The mechanical structure is simple and does not require a reversing motor. Only the shielding cover is adjusted by the pedal to achieve the effect of issuing different operating instructions, because the torque generated by the reversing motor causes greater loss to the motor;

[0036] In addition, the second double-headed motor is started to drive the second transmission roller to rotate. The second transmission roller also drives the aluminum alloy wheels on both sides to rotate, thereby driving the loader body to move. The front power tire is installed inside the embedded groove of the aluminum alloy wheel. The supporting diagonal rod can be flipped around the hinge point and supported by the shock-absorbing element. Its function is to reduce shock for the front power tire when the aluminum alloy wheel rotates. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] The present invention provides a pedal adjustment system for a small loader through improvement, comprising a loader body 2 and a loader steering wheel 3. The loader steering wheel 3 is mounted on one end of the top of the loader body 2, a loader seat 4 is mounted on the other end of the top of the loader body 2, an explosion-proof tire 6 is mounted on the end of the loader body 2 away from the pedal adjustment structure 7, a loader housing 1 is mounted on the top of the loader body 2, and footrests 5 are mounted on the bottom ends of both sides of the loader body 2;

[0055] A pedal adjustment structure 7 is installed at one end of the bottom of the loader body 2, and the pedal adjustment structure 7 assists the loader to operate through the pedal. The pedal adjustment structure 7 includes a second double-headed motor 737, a loader shovel 711, a first double-headed motor 722 and a water tank turntable 729;

[0056] Among them, the second double-headed motor 737 and the first double-headed motor 722 are installed at the bottom end of the loader body 2. The output end of the second double-headed motor 737 is installed with a second transmission roller 736. The second transmission roller 736 drives the loader shovel 711 to flip clockwise and counterclockwise through transmission.

[0057] The bottom of the loader body 2 is equipped with multiple sets of aluminum alloy frames 702, and the top of the aluminum alloy frame 702 is equipped with a cross connector 709. The middle position of the cross connector 709 runs through the second transmission roller 736. The cross connector 709 supports the second transmission roller 736 at the top of the aluminum alloy frame 702. One side of the second transmission roller 736 is installed on the output end of the second double-headed motor 737, and the second transmission roller 736 is driven to rotate by the second double-headed motor 737.

[0058] A transmission slant plate 738 is mounted on one end of the second transmission roller 736 away from the second double-headed motor 737. The second transmission roller 736 drives the transmission slant plate 738 to rotate. The top end of the transmission slant plate 738 is hingedly connected to a first transmission rod 721. The transmission slant plate 738 drives the first transmission rod 721 to rotate. The top end of the first transmission rod 721 is hingedly connected to an L-shaped transmission plate 718. The first transmission rod 721 drives the L-shaped transmission plate 718 to move around the center line of the second transmission roller 736.

[0059] The two sides of the top of the L-shaped transmission plate 718 are hinged with arc-shaped transmission claws 719, and the end of the arc-shaped transmission claw 719 away from the L-shaped transmission plate 718 is equipped with a herringbone meshing tooth 720;

[0060] A herringbone transmission gear 717 is provided on one side of the L-shaped transmission plate 718, and the herringbone transmission gear 717 and the herringbone meshing teeth 720 are driven by meshing. Through multiple sets of parts, the arc-shaped transmission claw 719 contacts the herringbone transmission gear 717 during movement and drives the herringbone transmission gear 717 to move, thereby achieving the purpose of driving the herringbone transmission gear 717 to rotate through the arc-shaped transmission claw 719 and the herringbone meshing teeth 720;

[0061] Among them, the central axis of the herringbone transmission gear 717 is hingedly connected to the loader body 2, and the second transmission gear 715 is installed on the side of the herringbone transmission gear 717 away from the L-shaped transmission plate 718, and a shielding side plate 716 is installed on the top of the second transmission gear 715. The second transmission gear 715 drives the shielding side plate 716 to flip around the center line of the second transmission gear 715, so that only the arc-shaped transmission claw 719 on one side can shift the herringbone transmission gear 717. The function of the shielding side plate 716 is to prevent the herringbone meshing teeth 720 on one side from shifting the herringbone transmission gear 717, and when the herringbone meshing teeth 720 on one side contact the herringbone transmission gear 717, the herringbone transmission gear 717 will rotate in the direction of the herringbone meshing teeth 720 on the side in contact with it;

[0062] Among them, a steering pulley 712 is provided at one end of the herringbone transmission gear 717. The structure can be further regulated by operating the steering pulley 712 by operating the pedal. The steering pulley 712 is rotated, and the steering pulley 712 is installed on one side of the top of the loader body 2. The output end of the steering pulley 712 is connected to the first transmission gear 713. The steering pulley 712 drives the first transmission gear 713 to rotate, and a transmission rack 714 is installed at the bottom end of the first transmission gear 713. The first transmission gear 713 drives the transmission rack 714 to move through meshing transmission. The first transmission gear 713, the transmission rack 714 and the second transmission gear 715 are meshed. The transmission rack 714 drives the second transmission gear 715 to rotate;

[0063] A connecting support frame 701 is provided on the side of the L-shaped transmission plate 718 away from the herringbone transmission gear 717, and the connecting support frame 701 is fixedly connected to the loader body 2;

[0064] The side of the L-shaped transmission plate 718 away from the herringbone transmission gear 717 is connected to the loader shovel plate 711, and the connection between the L-shaped transmission plate 718 and the loader shovel plate 711 is supported by the connecting support frame 701;

[0065] The rotation direction of the herringbone transmission gear 717 can be adjusted through this structure. The herringbone transmission gear 717 can further drive the loader shovel 711 to flip forward and reverse, and can control the loader shovel 711 to push and sweep toward the front end and to move inward, thereby achieving the function of assisting the loader to work through the pedal adjustment structure 7 when the loader is working;

[0066] The second double-headed motor 737 is started to rotate the second transmission roller 736. The side of the second transmission roller 736 away from the transmission inclined plate 738 is connected to the aluminum alloy wheel hub 705. The second transmission roller 736 also drives the aluminum alloy wheel hubs 705 on both sides to rotate. The aluminum alloy wheel hubs 705 are provided with shock absorbing elements 706 inside, and there are four groups of shock absorbing elements 706.

[0067] The top of the shock absorbing element 706 is connected to a supporting diagonal rod 707, and a hinge point 708 is hinged on one side of the supporting diagonal rod 707. The supporting diagonal rod 707 and the aluminum alloy wheel hub 705 are hingedly connected via the hinge point 708. The supporting diagonal rod 707 can be flipped around the hinge point 708 and is supported by the shock absorbing element 706.

[0068] The surface of the aluminum alloy wheel hub 705 is provided with a front power tire 704, which is installed in the inner groove of the aluminum alloy wheel hub 705. The shock absorbing element 706 is used to reduce the shock of the front power tire 704 when the aluminum alloy wheel hub 705 rotates. A supporting side plate 703 is installed on the side of the aluminum alloy wheel hub 705 away from the front power tire 704, and the aluminum alloy wheel hub 705 is connected to the loader body 2 through the supporting side plate 703, thereby driving the loader body 2 to move.

[0069] This structure can control the loader shovel 711 to push and sweep bulk materials such as soil, sand, lime and coal toward the front end and to push them inward by manually adjusting the steering pulley 712, thereby achieving the effect of assisting the loader in working through the pedal adjustment structure 7; when bulk materials such as soil, sand, lime and coal need to be cleaned, the loader shovel 711 is controlled to push the bulk materials toward the far end and push the bulk materials into a preset pit for burial; when bulk materials need to be processed in a centralized manner, the loader shovel 711 is controlled to reverse and push inward to gather the bulk materials in one place;

[0070] The output end of the first double-headed motor 722 is equipped with a first transmission roller 710, which drives the water tank turntable 729 to rotate. An L-shaped pedal 726 is provided at one end of the water tank turntable 729. The L-shaped pedal 726 controls the connection between the first transmission roller 710 and the water tank turntable 729.

[0071] The first double-headed motor 722 has two sets of output ends, and the first transmission roller 710 is installed on both sets of output ends. The first double-headed motor 722 drives the first transmission roller 710 to rotate;

[0072] A transmission spur gear 723 is fixedly mounted on the side of the first transmission roller 710 away from the first double-headed motor 722, and the first transmission roller 710 drives the transmission spur gear 723 to rotate;

[0073] The water tank rotary disc 729 is passed through the side of the first transmission roller 710 away from the transmission spur gear 723;

[0074] An L-shaped hook plate 724 is hingedly mounted on one end of the water tank turntable 729 near the transmission spur gear 723, and a first metal pressing plate 725 is mounted on the top of the L-shaped hook plate 724;

[0075] Among them, an L-shaped pedal 726 provided at one end of the water tank turntable 729 is hingedly connected to the loader body 2, a second metal pressure plate 727 is installed on one side of the L-shaped pedal 726, and a limit plate 728 is installed on the top of the L-shaped pedal 726;

[0076] When the user steps on the L-shaped pedal 726, the restriction of the L-shaped hook plate 724 by the limiting plate 728 is released, and the first metal pressure plate 725 pushes the L-shaped hook plate 724 toward the direction of the transmission spur gear 723 through its own elasticity, so that the L-shaped hook plate 724 hooks the transmission spur gear 723. When the L-shaped hook plate 724 and the transmission spur gear 723 are stuck, the water tank turntable 729 is driven to rotate by the transmission spur gear 723. Then, after the L-shaped hook plate 724 makes a circle and reaches the L-shaped pedal 726 again, if the user releases the foot pedal, the L-shaped pedal 726 is pushed back to its original position by the elastic second metal pressure plate 727, and the L-shaped hook plate 724 is again stuck by the limiting plate 728. At the same time, the water tank turntable 729 is stuck and fixed. If the user still steps on the foot pedal, the limiting plate 728 will not limit the position of the L-shaped hook plate 724. At this time, the water tank turntable 729 continues to rotate with the transmission spur gear 723.

[0077] A spraying joint 730 is installed on the side of the water tank turntable 729 away from the transmission spur gear 723, and there are two groups of spraying joints 730 and they are symmetrically distributed;

[0078] A spray joint 730 installed on one side of the water tank turntable 729 can spray mist to remove dust;

[0079] Among them, a Y-shaped support member 731 is installed around the spray joint 730, and an elastic element 732 is installed at the bottom end of the Y-shaped support member 731. A flip member 733 is hingedly installed on the top of the Y-shaped support member 731. The elastic element 732 pushes the flip member 733 to rotate around the Y-shaped support member 731, and a dust removal sprayer 734 is installed on one side of the flip member 733, which can drive the dust removal sprayer 734 to adjust the angle. A pressure joint 735 is installed on one side of the dust removal sprayer 734, so that the spray direction is outward. The dust removal sprayer 734 drives the pressure joint 735 to spray water to further spray dust removal. In addition, the dust removal sprayer 734 is provided with multiple groups of annular distribution around the water tank turntable 729, which is convenient for multi-directional spraying of dust removal spray;

[0080] This structure controls the operation of the loader by outputting instructions to the loader through the operating pedal adjustment system. Further operation of the pedal enables the spray joint 730 and the pressurizing joint 735 to assist the loader in its operation, remove dust for the loader, and further reduce the dust raised by bulk materials such as soil, sand, lime and coal when shoveling. The dust not only affects the driver's vision, but also affects the accuracy of the driver's operation, and increases the cleaning pressure of the loader.

[0081] Working principle: First, the first double-headed motor 722 drives the first transmission roller 710 to rotate, and the first transmission roller 710 drives the transmission spur gear 723 to rotate. The first transmission roller 710 is close to the water tank turntable 729 that passes through one side of the transmission spur gear 723. When the user steps on the L-shaped pedal 726, the limit plate 728's restriction on the L-shaped hook plate 724 falls off, and the first metal pressure plate 725 pushes the L-shaped hook plate 724 toward the direction of the transmission spur gear 723 through its own elasticity, so that the L-shaped hook plate 724 hooks the transmission spur gear 723. When the L-shaped hook plate 724 and the transmission spur gear 723 are stuck, the water tank turntable 729 is driven to rotate by the transmission spur gear 723. Then, after the L-shaped hook plate 724 makes a circle and reaches the L-shaped pedal 726, if the user releases the foot pedal, the L-shaped pedal 726 is The elastic second metal pressure plate 727 pushes to reset, and the L-shaped hook plate 724 is stuck by the limit plate 728 again. At the same time, the water tank turntable 729 is stuck and fixed. If the user still steps on the pedal, the limit plate 728 will not limit the position of the L-shaped hook plate 724. At this time, the water tank turntable 729 still rotates with the transmission spur gear 723. The spray joint 730 installed on one side of the water tank turntable 729 can spray spray dust removal, and the elastic element 732 pushes the flip part 733 to rotate around the Y-shaped support part 731, which can drive the dust removal sprayer 734 to adjust the angle, so that the spray direction is outward. The dust removal sprayer 734 drives the pressure joint 735 to spray water to further spray spray dust removal. In addition, the dust removal sprayer 734 is provided with multiple groups of ring-shaped distribution around the water tank turntable 729, which is convenient for multi-directional spraying of dust removal spray.

[0082] Then, the second double-headed motor 737 drives the second transmission roller 736 to rotate, and the cross connector 709 supports the second transmission roller 736 at the top of the aluminum alloy frame 702. The second transmission roller 736 drives the transmission inclined plate 738 to rotate, and the transmission inclined plate 738 drives the first transmission rod 721 to rotate. The first transmission rod 721 drives the L-shaped transmission plate 718 to move around the central axis of the second transmission roller 736. Through multiple sets of parts transmission, the arc-shaped transmission claw 719 contacts the herringbone transmission gear 717 during movement and drives the herringbone transmission gear 717 to move, thereby achieving the purpose of driving the herringbone transmission gear 717 to rotate through the arc-shaped transmission claw 719 and the herringbone meshing teeth 720;

[0083] In addition, the structure can be further regulated by operating the steering pulley 712 by operating the pedal. Specifically, by rotating the steering pulley 712, the steering pulley 712 drives the first transmission gear 713 to rotate, and the first transmission gear 713 drives the transmission rack 714 to move through the meshing transmission, and the transmission rack 714 drives the second transmission gear 715 to rotate, and the second transmission gear 715 drives the shielding side plate 716 to flip around the center line of the second transmission gear 715. Only the arc-shaped transmission claw 719 on one side can move the herringbone transmission gear 717. The function of the shielding side plate 716 is to prevent the herringbone meshing gears from engaging. 720 drives the herringbone transmission gear 717, and when the herringbone meshing teeth 720 on one side come into contact with the herringbone transmission gear 717, the herringbone transmission gear 717 will rotate in the direction of the herringbone meshing teeth 720 on the side in contact with it. The rotation direction of the herringbone transmission gear 717 can be adjusted through this structure. Further, the herringbone transmission gear 717 can drive the loader shovel 711 to flip forward and reverse, and can control the loader shovel 711 to push and sweep toward the front end and to move inward, thereby achieving the effect of assisting the loader in working through the pedal adjustment structure 7 when the loader is working.

[0084] Finally, the second double-headed motor 737 is started to drive the second transmission roller 736 to rotate. The second transmission roller 736 will also drive the aluminum alloy wheels 705 on both sides to rotate, thereby driving the loader body 2 to move. The front power tire 704 is installed inside the embedded groove of the aluminum alloy wheel 705. The supporting diagonal rod 707 can be flipped around the hinge point 708 and supported by the shock-absorbing element 706. Its function is to provide shock absorption for the front power tire 704 when the aluminum alloy wheel 705 rotates.
