Chinese patent application CN113853958A discloses a hilly orchard monorail self-propelled branch crusher, which is towed by a monorail vehicle to realize the mobile crushing operation of the hilly orchard, but the vibration is severe, resulting in safety hazards during operation. Summary of the invention

[0004] In view of the deficiency of large vibration amplitude in the crushers in the prior art, the present invention provides a direction-adjustable vibration-damping supporting mechanism and a use method of a monorail self-propelled branch crusher. On the one hand, the monorail self-propelled branch crusher in hilly orchards can realize the steering function to meet the needs of branch crushing on both sides of the track and debris throwing on three sides, thereby reducing the vibration amplitude of the crusher during operation. On the other hand, the direction-adjustable vibration-damping supporting walking mechanism can be used for monorail transport vehicles and mounted operating machinery thereof to improve operation stability and safety.

[0005] The present invention is realized by the following technical scheme, which provides a direction-adjusting vibration-damping supporting mechanism of a monorail self-propelled branch crusher, comprising a supporting platform for supporting the crusher, a direction-adjusting mechanism for adjusting the direction of the crusher, and a meshing mechanism adapted to the track; the supporting platform comprises an upper loading platform, a buffer vibration-damping pad, and a lower loading platform arranged in sequence from top to bottom, the upper loading platform is fixedly connected to the crusher, and the lower loading platform is fixedly connected to a mounting frame of the meshing mechanism; the direction-adjusting mechanism comprises a steering system for driving the upper loading platform to rotate relative to the lower loading platform;

[0006] The meshing mechanism includes a mounting frame, and a driving wheel and a load-bearing wheel mounted on the mounting frame, the load-bearing wheel is supported on the upper surface of the track, the driving wheel is meshed with a transverse rack fixed on the bottom surface of the track, and the driving wheel is connected to a driving motor.

[0007] This solution uses the upper loading platform as the installation carrier of the branch crusher. It plays a vibration reduction role by setting buffer vibration-damping gaskets. The steering system drives the lower loading platform to rotate, thereby driving the crusher to turn. The driving motor drives the driving wheel to rotate. The rotation of the set driving wheel enables the equipment to move along the track. The weight of the equipment is borne by the load-bearing wheels to ensure the stable movement of the equipment.

[0008] As an optimization, the mounting frame is also equipped with lateral wheels located on the left and right sides of the track, and the wheel surface of the lateral wheels fits the side of the track. This optimization solution reduces the friction resistance of the equipment walking and reduces the lateral shaking amplitude of the supporting mechanism by setting the lateral wheels that fit the side of the track.

[0009] As an optimization, a driven gear is fixedly provided at the center of the bottom surface of the upper loading platform, and a lifting hole with an opening facing downward is provided at the center of the driven gear. A number of circumferentially arranged positioning pins are also fixedly provided on the bottom surface of the upper loading platform, and the positioning pins extend downward into the downloading platform, and the center of the circle where the positioning pins are located is located on the central axis of the driven gear; the direction adjustment mechanism also includes a lifting system, and the lifting system includes a lifting rod adapted to the lifting hole, and a lifting device that drives the lifting rod to move upward and lift the upper loading platform; the steering system includes a driving gear and a rotating mechanism that drives the driving gear to rotate, and when the upper loading platform rises until the positioning pin is disengaged from the downloading platform, the driving gear meshes with the driven gear, and when the positioning pin is inserted into the downloading platform, the driving gear is separated from the driven gear. The setting of this optimization scheme is that when the crusher does not need to turn, the positioning pins are used to ensure the relative fixation of the upper loading platform and the unloading platform along the circumferential direction. When turning is required, the upper loading platform is lifted upward by the lifting device to disengage the positioning pins from the unloading platform, and the active gear is used to drive the driven gear to rotate, so that the upper loading platform rotates to adjust the working direction of the crusher. After the direction of the crusher is adjusted to the right position, the lifting device drops the upper loading platform to make the positioning pins fall into the unloading platform, and the upper loading platform and the unloading platform return to a relatively fixed state.

[0010] As an optimization, the positioning pins are arranged in two circles, inner and outer, and the center angle of two adjacent positioning pins in each circle is 15 degrees. The setting of this optimization scheme enables the crusher to be used when the angle is an integer multiple of 15, which improves the convenience of use.

[0011] As an optimization, a polygonal positioning block is fixed at the bottom center of the upper loading platform, the driven gear is located at the bottom center of the polygonal positioning block, the polygonal positioning block extends downward through the buffer and vibration reduction pad to the unloading platform, and a positioning hole adapted to the polygonal positioning block is provided on the unloading platform. This optimization scheme further ensures the relative fixing effect of the upper loading platform and the unloading platform along the circumferential direction by providing the polygonal positioning block and the positioning hole, thereby further improving the stability of the crusher during operation.

[0012] As an optimization, the lifting device includes a first worm gear arranged in a transverse direction, a first turbine gear meshed with the first worm gear, and a first gear gear arranged coaxially with the first turbine gear. A vertical rack gear meshed with the first gear gear is fixed on the lifting rod, and a lifting rocker is installed at one end of the first worm gear. This optimization scheme adopts a turbine-worm gear mechanism to transmit force, and utilizes a gear rack mechanism to realize the lifting and lowering of the lifting rod. The force transmission reliability is high, and the reliability of the lifting operation is ensured.

[0013] As an optimization, the rotating mechanism includes a second worm gear arranged in the transverse direction, a second turbine gear meshing with the second worm gear, and a driving bevel gear coaxial with the second turbine gear, a driven bevel gear meshing with the driving bevel gear is installed on the axle of the driving gear, and a steering rocker is installed at one end of the second worm gear. This optimization scheme adopts a turbine worm gear mechanism to transmit force, and utilizes gear meshing to realize the steering of the crusher, with good structural stability, ensuring the reliability of the steering operation.

[0014] As an optimization, the outer side of the unloading platform is equipped with a plurality of spring buckles arranged in sequence along the circumferential direction, and the upper loading platform, the buffer vibration-damping gasket and the unloading platform are relatively fixed in the axial direction through the spring buckles. This optimization scheme realizes the relative fixation of the upper loading platform, the buffer vibration-damping gasket and the unloading platform in the axial direction through the spring buckles, has a simple structure, and is easy to open and lock.

[0015] The present invention also provides a method for using the above-mentioned directional vibration-reducing supporting mechanism, including the following aspects:

[0016] 1. The lateral wheels are used to increase the bite force between the wheels and the track, thereby reducing the vibration amplitude on both sides of the track when the hilly orchard single-track self-propelled branch crusher is operating. The vibration damping pads are used to reduce the impact of the vibration on the track caused by the discontinuous cutting of branches by the branch crusher.

[0017] 2. When the crusher needs to turn, release the spring buckle, rotate the lifting rocker to lift the upper loading platform upward, disengage the polygonal positioning block and the positioning pin from the unloading platform, move the driven gear up to the position meshing with the driving gear, and then rotate the steering rocker to drive the driving gear to rotate, and use the driving gear to drive the driven gear to rotate, so that the upper loading platform installed with the crusher rotates to realize the turning of the crusher; after the crusher turns to the right position, rotate the lifting rocker in the opposite direction to lower the upper loading platform until the positioning pin and the polygonal positioning block are inserted into the unloading platform, and then lock the upper loading platform, the buffer and vibration reduction gasket and the unloading platform through the spring buckle;

[0018] 3. Mount a misting machine, anti-frost machine or harvester on the upper platform to complete the misting, anti-frost and harvesting operations respectively.

[0019] The beneficial effects of the present invention are: it solves the problem of unidirectional operation of the monorail self-propelled branch crusher in hilly orchards, realizes multi-directional operation through the turning of the crusher, and realizes the turning of the crusher through the lifting and rotation of the upper platform, thereby ensuring the reliable operation of the upper platform when it is in high and low positions; the vertical vibration amplitude of the crusher during operation is reduced by the arranged buffer and vibration-damping gaskets, and the vibration of the left and right directions of the track is reduced by the arranged lateral wheels, which provides an effective measure for the maintenance of the track system and prolongs its service life, and is suitable for other small-sized mounted machinery.

DETAILED DESCRIPTION

[0029] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0030] like Figure 1 The illustrated embodiment is a directional damping support mechanism of a monorail self-propelled branch crusher, comprising a support platform 28 supporting a crusher 27, a directional adjustment mechanism 7 for adjusting the direction of the crusher, and a meshing mechanism adapted to the track. The crusher targeted by this embodiment is a monorail self-propelled branch crusher for hilly orchards disclosed in CN113853958A. The directional damping support mechanism of this embodiment can reduce the vibration amplitude of the crusher during operation, and maintain the safety and stability of the operation process.

[0031] The support platform includes an upper platform 3, a buffering and vibration-damping gasket 2 and a lower platform 1 which are arranged in sequence from top to bottom, forming a three-layer platform structure. A positioning hole for the operating machine is provided on the upper platform. The upper platform is fixedly connected to the crusher, and the lower platform is fixedly connected to the mounting frame of the meshing mechanism. A plurality of spring buckles 15 arranged in sequence along the circumferential direction are installed on the outer side of the lower platform. The upper platform, the buffering and vibration-damping gasket and the lower platform are relatively fixed in the axial direction by the spring buckles. The buffering and vibration-damping gasket is located between the lower platform and the upper platform to play a vibration-damping role. A vertical fixing position 5 adapted to the spring buckle 15 is fixed on the top of the upper platform, and a buckle handle 6 is provided on the spring buckle 15.

[0032] The direction adjustment mechanism includes a lifting system and a steering system that drives the upper platform to rotate relative to the unloading platform. Specifically, a driven gear 18 is fixedly provided at the center of the bottom surface of the upper platform, and a lifting hole with an opening facing downward is provided at the center of the driven gear. The axis of the gear extends in the vertical direction. A plurality of circumferentially arranged positioning pins are also fixedly provided on the bottom surface of the upper platform. The positioning pins extend downward into the unloading platform. The unloading platform and the buffer and vibration-damping gasket are both provided with pin holes that match the positioning pins. The center of each circle where the positioning pins are located is located on the central axis of the driven gear. The radial and circumferential relative fixation of the upper platform 3, the buffer and vibration-damping gasket 2 and the unloading platform 1 is achieved by the positioning pins. The positioning pins of this embodiment are arranged as inner and outer circles, and the corresponding central angle of two adjacent positioning pins in each circle is 15 degrees. The positioning pins of the outer circle are large circumferential positioning pins 19, and the positioning pins of the inner circle are small circumferential positioning pins 20.

[0033] The upper loading platform includes an upper loading platform surface 21 and a branch shredder fixing position 4 fixed on the top of the upper loading platform surface, which is used to fix and connect the branch shredder. A polygonal positioning block 17 is also fixed at the bottom center of the upper loading platform. The driven gear is located at the bottom center of the polygonal positioning block. The polygonal positioning block extends downward through the buffer and vibration-damping gasket to the downloading platform. A positioning hole adapted to the polygonal positioning block is provided on the downloading platform. The positioning block is used to improve the relative fixing effect of the upper loading platform 3, the buffer and vibration-damping gasket 2 and the downloading platform 1 in the radial and circumferential directions. The polygonal positioning block of this embodiment is a square positioning block. The bottom surface of the square positioning block forms a barrier to the lifting rod so that the lifting rod lifts the upper loading platform. When the driving gear is meshed with the driven gear, the polygonal positioning block and the positioning hole are in a separated state. When the polygonal positioning block is inserted into the positioning hole, the driving gear and the driven gear are in a separated state.

[0034] The downloading platform includes a downloading platform surface 14, and a square positioning hole 12, a large circumference positioning hole 13, a small circumference positioning hole 16 and a spring buckle 15 arranged on the downloading platform surface. The square positioning hole is adapted to the square positioning block, the large circumference positioning hole is adapted to the large circumference positioning pin 19, and the small circumference positioning hole 16 is adapted to the small circumference positioning pin 20. The square positioning block 17 on the upper loading platform 3 passes through the square positioning hole 12 on the downloading platform 1 and the buffer vibration damping gasket 2, and plays a role in vertical positioning and horizontal fixing. The large circumference positioning pin 19 and the small circumference positioning pin 20 on the upper loading platform respectively pass through the large circumference positioning hole and the small circumference positioning hole on the downloading platform 1 and the buffer vibration damping gasket, and play a role in circumferential fixing. The driven gear on the upper loading platform rotates under the adjustment of the direction adjustment mechanism and drives the upper loading platform to achieve direction adjustment.

[0035] Specifically, the three-layer stacked carrier relies on positioning blocks and positioning pins to achieve radial and circumferential fixation, and relies on spring buckles to achieve axial fixation. The square positioning block of the upper platform is connected to the unloading platform and the square positioning hole of the buffer and vibration damping gasket; the large circumference positioning pins and small circumference positioning pins of the upper platform are connected to the unloading platform, the large circumference positioning holes and small circumference positioning holes of the buffer and vibration damping gasket. There are 16 positioning pins and positioning holes respectively, each evenly distributed on the circumference, and the positions of the small circumference and large circumference positioning pins are staggered by 15°.

[0036] The lifting system includes a lifting rod adapted to the lifting hole, and a lifting device that drives the lifting rod to move upward and lift the upper platform. Specifically, the lifting device includes a first worm gear arranged in a transverse direction, a first turbine gear meshed with the first worm gear, and a first gear gear coaxially arranged with the first turbine gear. A vertical rack 24 meshed with the first gear gear is fixed on the lifting rod, and a lifting rocker 22 is installed at one end of the first worm gear. The first worm gear, the first turbine gear, the first gear gear and the vertical rack gear 24 form a lifting gear train, and the lifting gear train rotates under the action of the lifting rocker gear. The lifting rod in the lifting gear train pushes the upper platform vertically upward, and finally suspends and meshes the gear under the upper platform with the steering gear train.

[0037] The steering system includes a driving gear and a rotating mechanism for driving the driving gear to rotate. When the upper loading platform rises until the positioning pin is disengaged from the unloading platform, the driving gear meshes with the driven gear. When the positioning pin is inserted into the unloading platform, the driving gear is separated from the driven gear. The rotating mechanism includes a second worm arranged in the transverse direction, a second turbine meshed with the second worm, and a driving bevel gear coaxial with the second turbine. A driven bevel gear meshed with the driving bevel gear is installed on the axle 25 of the driving gear, and a steering rocker 23 is installed at one end of the second worm. The second worm, the second turbine, the driving bevel gear and the driven bevel gear form a steering gear train. The steering gear train rotates under the action of the steering rocker. The steering shaft in the steering gear train rotates the gear connected to the upper loading platform, thereby driving the crusher to complete the direction adjustment.

[0038] The first worm, the first turbine, the second worm, the second turbine, the lifting rocker and the steering rocker are all rotatably mounted on the housing 26, and the housing 26 is fixedly connected to the mounting frame of the meshing mechanism. When the lifting rod is in a low position, the driving gear is separated from the driven gear, and when the lifting rod is in a high position, the driving gear is meshed with the driven gear.

[0039] The meshing mechanism includes a walking mechanism protection frame 8, a mounting frame, and a driving wheel 9 and a load-bearing wheel 11 mounted on the mounting frame. There are two driving wheels, both of which are meshed with the transverse rack fixed on the bottom surface of the track, and the driving wheel is connected to the driving motor to provide forward power for the crusher, which is the driving part of the adjustable vibration-damping supporting walking mechanism. The mounting frame is also equipped with two sets of lateral wheels 10 located on the left and right sides of the track respectively. The wheel surface of the lateral wheel is tightly fitted with the side of the track to ensure stable meshing, prevent the adjustable vibration-damping supporting walking mechanism from overturning, and realize the left and right fixation of the crusher and the track. The surface is provided with a vibration-damping patch to reduce the left and right vibration amplitude to ensure the need for turning. The outer part of the walking protection frame 8 is an open double wheel to ensure that it bypasses the track support rod. There are two load-bearing wheels, which are supported on the upper surface of the track respectively to support the gravity on the track, and together with the driving wheel 9, the crusher and the track are fixed up and down, providing stable support for the operation machinery mounted on the upper part of the adjustable vibration-damping supporting walking mechanism. During the mobile operation, the traction mechanism drives the driving wheel 9 to rotate, and the lateral wheels 10 and the load-bearing wheels 11 also rotate in coordination, so as to realize the mobile operation of the crusher and reduce the vibration amplitude. The driving wheel 9, the lateral wheels 10 and the load-bearing wheels 11 are all located inside the walking mechanism protection frame 8.

[0040] When the directional vibration-damping supporting mechanism of this embodiment is used, it includes the following aspects:

[0041] 1. By increasing the bite force between the lateral wheels and the track, the vibration amplitude on both sides of the track of the hilly orchard single-track self-propelled branch crusher is reduced during operation. The impact of the vibration caused by the discontinuous cutting of branches by the branch crusher on the track is weakened by the buffering and vibration-damping gaskets; that is, the directional vibration-damping supporting walking mechanism can reduce the vibration amplitude of the crusher during operation and maintain the safety and stability of the operation process.

[0042] 2. When the crusher needs to turn, release the spring buckle to release the axial movement restriction of the carrier, rotate the lifting rocker to lift the upper carrier upward, lift the crusher and suspend it, disengage the polygonal positioning block and the positioning pin from the downloading platform, move the driven gear up to the position meshing with the driving gear, and then rotate the steering rocker to drive the driving gear to rotate, and use the driving gear to drive the driven gear to rotate, so that the upper carrier installed with the crusher rotates to realize the turning of the crusher; after the crusher turns to the right position, rotate the lifting rocker in the opposite direction to lower the upper carrier until the positioning pin and the polygonal positioning block are inserted into the downloading platform, and then lock the upper carrier, the buffer and vibration-damping gasket and the downloading platform through the spring buckle; when the hilly orchard monorail self-propelled branch crusher is in operation, it is necessary to crush the branches on both sides of the track and lay the branch debris on both sides of the track, and collect the branch debris along the track direction for other uses.

[0043] 3. Mount a mist spreader, anti-frost machine or harvester on the upper platform to complete misting, anti-frost and harvesting operations respectively. The adjustable vibration-reducing supporting walking mechanism can be used in combination to improve operation stability.

[0044] The method of using the present invention to mount a crusher or other operating machinery on a hilly orchard monorail transport system includes the following aspects:

[0045] 1. The mounting machine and the adjustable vibration-damping supporting walking mechanism are fixed through the positioning hole of the upper loading platform. The adjustment of the operating machine is achieved by manipulating the lifting rocker and the steering rocker. After the adjustment is completed, the upper loading platform needs to be lowered and the spring buckle is fastened.

[0046] 2. The directional vibration-reducing support travel mechanism can meet the agronomic requirements of the multi-directional operation of the hilly orchard monorail self-propelled branch crusher, and can realize the cutting and crushing of branches, crushing and throwing, so that the debris is spread on the surface to increase the fertility of the orchard, or collect the debris for other purposes to increase the income of the people; it can reduce the vibration amplitude during the crushing operation, which is helpful for track maintenance, prolonging the service life of the monorail transportation system, and improving the crushing quality to a certain extent. The hilly orchard monorail transport vehicle can be mounted with a variety of small orchard operating machinery, and the directional vibration-reducing support travel mechanism can be slightly improved and adapted to solve the vibration problem of the monorail vehicle itself.

[0047] The directional damping and supporting walking mechanism optimizes the vibration problem of the hilly orchard monorail transport vehicle and the self-propelled branch crusher based on the hilly orchard monorail transport system, which helps to extend the service life of the track system, improve the stability of the crushing operation, and meet the needs of multi-directional crushing operations. The damping and directional adjustment functions provided by the present invention can also be adapted to other small monorail operating machines in hilly orchards to improve their safety and stability.

[0048] The present invention provides a turning capability for a pulverizing mechanism of a monorail self-propelled branch pulverizer in a hilly orchard, realizes flat throwing of debris on both sides of the debris track and collection of debris on the track, and proposes a multi-purpose method of the present invention, that is, the present invention can also be used for mounting operating machinery in other hilly orchard monorail transportation systems to play a vibration reduction and direction adjustment role; the track engagement mechanism involved in the present invention can also be used for a monorail tractor to play a vibration reduction role.

Technical features not described in the present invention can be achieved by or by using existing technologies, which will not be described here.

After the crusher is turned to the right position, rotate the lifting rocker in the opposite direction to lower the upper loading platform until the positioning pin and the polygonal positioning block are inserted into the unloading platform, and then lock the upper loading platform, the buffer and vibration-damping gasket and the unloading platform with the spring buckle; (3) A misting machine, frost prevention machine or harvester is mounted on the upper platform to complete misting, frost prevention and harvesting operations respectively.
