Description
Technical Field
[0001] The utility model belongs to the technical field of orchard rail transportation, and in particular relates to a transportation device for mountain orchards. Background Art
[0002] With the rapid development of facility agriculture in my country, the scale of planting is getting larger and larger, and fruit trees are planted in uneven mountains. Fruit farmers need to transport the fruits after picking them. Currently, they mostly rely on manual transportation, but pure manual transportation is not only labor-intensive and inefficient, but also costly.
[0003] To this end, the utility model with application number 202321203265.2 discloses a fruit tree picking track device, including a loader, a track, a limit clamp connected and fixed at the lower part of the loader, the limit clamp is rotatably connected to the lower part with two pulleys to form a transmission device, the transmission device is sleeved on the outer periphery of the track, sleeves are provided at the four ends of the lower part of the loader, a buffer is connected inside the sleeve, a support rod is fixedly connected to the lower end of the buffer, a universal joint is connected to the lower end of the support rod, a roller is connected to the other end of the universal joint, and slide grooves are opened on both sides of the upper part of the track, and the rollers are arranged in the slide grooves for rolling.
[0004] The above scheme supports the loader by supporting rods, so that the load on the pulley is reduced, and the loader has the advantage of good stability; however, during mountain transportation, due to the winding and rugged mountains and the many gravel and potholes on the road, the track setting is difficult, so the track is usually set as a single track. For the single track design, if the pulley is in direct contact with the ground, the pulley will be subjected to greater pressure, which will cause greater wear on the pulley, and when passing through the gravel and pothole section, it is very likely that the loader will be unevenly stressed, which will cause the loader to overturn.
[0005] Therefore, there is an urgent need for a more stable transportation device that is suitable for complex terrains. Utility Model Content
[0006] The utility model aims to provide a monorail type transport device for mountain orchards to improve the stability of the mountain transport device.
[0007] In order to solve the technical problems mentioned above, the utility model specifically adopts the following technical solutions: a transportation device for mountain orchards, comprising a track and at least one loading vehicle, the track being a single track arranged in the air, and also comprising a fixed bracket fixedly arranged at the bottom of the loading vehicle, and at least two groups of pulley groups symmetrically installed at the bottom of the loading vehicle, any of the pulley groups comprising a mounting bracket fixedly connected to the fixed bracket, and a first pulley and a second pulley rotatably arranged on the mounting bracket, and the first pulley is in contact with a side of the track close to the loading vehicle, and the second pulley is in contact with a side of the track close to the ground, and the acute angle between the line connecting the center points of the first pulley and the second pulley and the extension direction of the track is 30°-60°; a traveling vehicle is detachably arranged at the traveling end of the loading vehicle, and the traveling vehicle comprises a chassis, a plurality of third pulleys in contact with the track and a plurality of wheels in contact with the ground are arranged at the bottom of the chassis, and a power mechanism and a steering mechanism are also arranged on the upper surface of the chassis.
[0008] As an improvement, the mounting bracket includes a first bracket, a second bracket and a third bracket, the first bracket and the second bracket are arranged in parallel along the vertical direction of the track and are respectively located above and below the track, the first bracket is fixedly connected to the fixed bracket, and the first bracket and the second bracket are connected through the third bracket; the first pulley is rotatably set on the first bracket, and the second pulley is rotatably set on the second bracket.
[0009] As an improvement, the lengths of the first pulley, the second pulley and the third pulley are all greater than the width of the track, the middle parts of the first pulley, the second pulley and the third pulley are respectively recessed to form a recessed portion, and the protrusions at both ends are respectively formed to form a protruding portion, so that when the first pulley, the second pulley and the third pulley slide on the track, the track is always located in the recessed portion.
[0010] As an improvement, the loading vehicle comprises a shell with an opening on the top, a door is arranged on the side wall of the shell, and a plurality of collecting frames are arranged inside the loading vehicle.
[0011] As an improvement, the vehicle door is an upper and lower opening and closing type vehicle door. When the vehicle door is in an open state, the bottom of the vehicle door is hinged to the bottom of the loading vehicle, and the other end is in contact with the ground.
[0012] As an improvement, a plurality of through holes are provided on the vehicle door.

[0014] As an improvement, the number of the collection frames is 2.
[0015] As an improvement, the acute angle between the line connecting the center points of the first pulley and the second pulley and the horizontal direction is 45°.
[0016] As an improvement, the traveling vehicle is also provided with a lighting lamp.
[0017] The principle and beneficial effect of the present invention are as follows: for roads with many gravel and potholes such as mountains, it is difficult and costly to set up double tracks. Therefore, a single track is used for transportation in the present application, which is more suitable for situations with poor road conditions such as mountains, and effectively reduces the cost of track laying. At the same time, the present application makes adaptive improvements to the loader and its pulley block, wherein, by replacing the traditional single pulley with a pulley block with a certain inclination angle, the gravity of the loader exerted on the pulley and the track can be effectively buffered, thereby effectively preventing the wear of the pulley and the track, and making the loader more stable. In addition, the traditional method of directly setting the pulley on the ground to make it move on the ground is changed to a method in which the pulley directly contacts the track and slides directly on the track instead of sliding on the ground, which can effectively avoid the wear of the pulley on the road surface caused by gravel, thereby further protecting the pulley, and effectively avoiding the problem of the loader rolling over when the pulley passes through a pothole-prone road surface.
[0018] In addition, the loader in the present application is provided with a detachable traveling vehicle. When the loader has no forward power or insufficient power to move forward smoothly on a flat road, the traveling vehicle can drive the loader to move forward, which is convenient and reliable.

[0032] The embodiment is basically as follows Figure 1-4 As shown:
[0033] like Figure 1 As shown, the utility model provides a transportation device for mountain orchards, including a track 2 suspended on a road surface. In order to adapt to complex terrains such as mountains while reducing transportation costs, the track 2 is a single track, and a plurality of loading carts 1 for loading crops such as fruits are slidably arranged above the track 2. A hook is arranged at the front and rear ends of each loading cart 1. A user can connect another loading cart through a hook at the rear end of the loading cart 1 according to transportation needs to form a multi-section carriage structure, thereby improving transportation efficiency when the transportation volume is large; at the same time, in the case of insufficient traveling power on flat ground, etc., the user can connect a traveling vehicle 6 at the front end of the loading cart 1 through a hook, and the traveling vehicle 6 drives the loading cart 1 forward.
[0034] like Figure 2A fixed bracket 301 is fixedly arranged at the bottom of the loading cart 1, and the loading cart 1 is slidably arranged on the track 2 through at least two groups of pulley groups symmetrically arranged at the bottom of the loading cart 1, and any specific pulley group includes a mounting bracket, a first pulley 4 and a second pulley 5, wherein the mounting bracket includes a first bracket 302 and a second bracket 303 which are arranged in parallel along the vertical direction of the track and are respectively located above and below the track 2, and a third bracket 304 for connecting the first bracket 302 and the second bracket 303; wherein the first bracket 302 is fixedly connected to the fixed bracket 301, and the two ends of the first bracket are connected to the two ends of the second bracket through the third bracket, and the axial direction of the third bracket is at an acute angle of 30°-60° with the extension direction of the track. Exemplarily, the third bracket 304 includes mutually parallel and relative to the track 2. There are two sections, one end of the third bracket 304 is fixed to the first bracket 302, and the other end is fixed to the second bracket 303, so that the acute angle between the third bracket 304 and the horizontal direction is 30°-60°. (To ensure the connection strength, the brackets, as well as the fixed bracket 301 and the loading vehicle 1 can be fixed by welding or bolting), the first pulley 4 and the second pulley 5 are rotatably arranged in the middle of the first bracket 302 and the second bracket 303 respectively, and the first pulley 4 is in contact with the side of the track close to the loading vehicle 1, and the second pulley 5 is in contact with the side of the track close to the ground, so that the first pulley 4 and the second pulley 5 can rotate along the track 2 at the same time, thereby driving the loading vehicle 1 to move, and the acute angle between the line connecting the center points of the first pulley 4 and the second pulley 5 and the horizontal direction is also 30°-60°.
[0035] In some embodiments, the acute angle between the line connecting the center points of the third bracket 304 or the first pulley 4 and the second pulley 5 and the extension direction of the track 2 is 45°.
[0036] In some embodiments, the traveling end of the loader 1 is detachably provided with a traveling vehicle 6, which includes a chassis 601, and a plurality of third pulleys 602 in contact with the track 2 are provided at the bottom of the chassis 601. The third pulley 602 is also installed at the bottom of the chassis through a bracket. The difference between the bracket and the bracket at the bottom of the loader 1 is that the shape of the bracket can be adaptively adjusted according to the shape and position of the chassis, and a plurality of wheels 603 in contact with the ground (specifically, 4 wheels, symmetrically arranged on both sides of the track 2 in pairs), such as Figure 3 The upper surface of the chassis is also provided with a power mechanism 604 and a steering mechanism 605. Since the power mechanism 604 and the steering mechanism 605 are conventional components of the traveling vehicle 6, those skilled in the art can select them according to actual conditions, and no further details are given here. At the same time, a lighting lamp 7 is also provided on the steering mechanism 605 for illuminating the road surface in insufficient light.
[0037] In some embodiments, the lengths of the first pulley 4, the second pulley 5 and the third pulley 602 are all greater than the width of the track 2, and the middle parts of the first pulley 4, the second pulley 5 and the third pulley 602 are respectively recessed to form a recessed portion, and the protrusions at both ends are respectively raised to form raised portions, so that when the first pulley 4, the second pulley 5 and the third pulley 602 slide on the track 2, the track 2 is always located in the recessed portion, and the raised portions on both sides of the pulley can limit the position of the pulley to prevent each pulley from deviating from or slipping off the track.
[0038] In some embodiments, the specific structure of the loading vehicle 1 is as follows Figure 4 , including a shell 103, wherein there is no cover on the top of the shell 103, and multiple collection frames 102 are placed inside the shell 103, one or two side walls are left with openings for the collection frames 102 to pass through, and a car door 101 is arranged at the opening, and specifically, the bottom of the car door 101 is hinged to the bottom of the shell 103, and a lock is installed on the shell 103 to lock the car door 101. When the car door 101 is in an open state, the free end of the car door 101 contacts the ground, thereby guiding the collection frame 102 to slide to the ground, thereby achieving the effect of saving effort. Preferably, when the vehicle door 101 is opened on a horizontal ground, the angle between the vehicle door 101 and the horizontal direction is 20°-45° (preferably 30°. With this design, the collection frame 102 can smoothly slide along the vehicle door 101 to the ground, but at the same time, the sliding speed of the collection frame 102 will not be too fast to cause damage to the fruits and vegetables). In addition, a plurality of through holes are evenly distributed on the vehicle door 101, thereby reducing the weight of the vehicle door and reducing the friction between the collection frame 102 and the vehicle door 101, thereby facilitating the removal of the collection frame 102 along the vehicle door 101.
[0039] In some embodiments, two collecting frames 102 are placed inside each loading vehicle 1 .
[0040] The present application adopts a form of combining a pulley assembly with a certain inclination angle with a single track, wherein the pulley slides directly on the track without contacting the ground, thereby comprehensively providing a more stable, lower-cost transportation device suitable for complex terrains such as mountains.
