Abstract
Description
Technical Field
[0001] The utility model relates to a storage rack, in particular to a self-balancing storage rack structure for a track machine. Background Art
[0002] In recent years, agricultural transport machinery has gradually become popular. However, due to the large number of mountainous areas in my country, there are still many places that cannot be reached by tractors. The transportation efficiency of mountain crops, including fruits and vegetables, is still low, and large-scale planting cannot be formed.
[0003] Therefore, rail conveyors have appeared on the market. They lay tracks on mountainous areas, which can enable the conveyor to start and stop at any time in the mountains to load and transport agricultural products. Such rail conveyors usually include tractors, trailers and tracks. The tractors and trailers are mounted on the tracks and move along the tracks. When in use, the tractor serves as the power output and runs on the tracks with the trailer, while the agricultural products are stored on the trailer. Since the operating environment of rail conveyors is mostly mountainous, its tracks are steeply inclined and curved, which may cause the agricultural products stored in the trailer to roll down, causing damage to the agricultural products and seriously affecting the economic income of farmers.
[0004] Therefore, how to prevent agricultural products from rolling off the trailer during operation has become a technical problem that needs to be solved urgently in the industry. Rail conveyors that solve this technical problem have also appeared on the market, but the existing rail conveyors that prevent agricultural products from rolling off have problems such as insufficient structural optimization and poor performance. Summary of the Invention
[0005] The utility model aims to solve the existing technical problem and provide a self-balancing storage rack structure for a track machine, which achieves self-balancing in the trailer by the gravity of the storage basket itself, thereby preventing the agricultural products in the storage basket from rolling down.
[0006] The technical solution adopted by the utility model to solve the above technical problems is:
[0007] The utility model discloses a self-balancing storage rack structure for a track machine, which is arranged on a trailer frame and comprises a storage rack. The top of the storage rack is hingedly hung on the trailer frame, and an arc guide rail is provided at the bottom. The trailer frame is provided with a guide wheel for guiding the arc guide rail, and a shock-absorbing mechanism is provided between the guide wheel and the trailer frame. When the trailer frame is in an inclined state along the track of the track machine, the storage rack is subjected to the effect of its own gravity and always maintains a vertical state with the hinged suspension point with the trailer frame as a fulcrum.
[0008] The trailer frame is installed on the track of the track machine and moves with the track. The storage rack is hinged and suspended on the trailer frame. In this way, the storage rack is always in a vertical state relative to the trailer frame due to its own gravity. In this process, in order to keep the storage rack stable, we have added arc guide rails and guide wheels to keep the storage rack vertical and directional to avoid shaking. Moreover, we have installed a shock-absorbing mechanism between the guide wheels and the trailer frame. When the storage rack is full of agricultural products, the shock-absorbing mechanism has a buffering ability for the storage rack, and also makes the friction between the arc guide rail and the guide wheel always maintain a relatively appropriate state, avoiding the situation where the arc guide rail cannot move relative to the guide wheel.
[0009] Limit blocks are provided at both ends of the storage rack. When the storage rack rotates around the hinged suspension point, the arc guide rail slides over the guide wheel, and the limit blocks prevent the arc guide rail from separating from the guide wheel.
[0010] The limiting block is screwed to the mounting plate, and the mounting plate is arranged on the storage rack.
[0011] Compared with the prior art, the present invention provides limit blocks at both ends of the storage rack to prevent the arc guide rail of the storage rack from being separated from the guide wheel due to excessive tilt angle when the trailer rack is running.
[0012] The storage rack is divided into two layers, including a large storage basket and a small storage basket. The arc guide rail is fixed on the large storage basket, and the small storage basket is located in the space between the large storage basket and the arc guide rail.
[0013] The size of the storage space of the storage rack means the transportation efficiency of agricultural products. Therefore, we maximize the storage space in the limited design space. That is: in addition to the large storage basket, we make full use of the space between the large storage basket and the arc guide rail to place small storage baskets, thereby greatly improving the storage capacity.
[0014] The shock absorbing mechanism includes a wheel seat fixed to the wheel axle of the guide wheel, a limiting plate arranged at the bottom of the wheel seat, and a pin arranged at the bottom of the limiting plate. A spring is sleeved on the pin shaft and inserted into the pin hole of the trailer frame. The pin shaft also has an external thread. By screwing a nut on the external thread, the pin shaft is always in the pin hole. The guide wheel not only has a guiding function for the circular arc guide rail, but also has a supporting function.
[0015] The setting of the shock-absorbing mechanism greatly reduces the degree of bumpiness of the storage rack, thereby protecting the agricultural products in the storage rack. Moreover, the setting of the shock-absorbing mechanism can effectively keep the connecting force between the arc guide rail and the guide wheel within an appropriate range at all times, so that the relative movement between the arc guide rail and the guide wheel becomes smooth.
[0016] The storage rack is connected to the trailer frame through an articulated suspension mechanism, which includes a hinged plate and a suspension rope. The hinged plate is connected to the top of the trailer frame through a hinged shaft, and four suspension holes are provided on the hinged plate. The four suspension holes correspond to the four connection corners of the storage rack one by one, and the corresponding suspension holes and connection corners are connected together through a suspension rope.
[0017] A suspension rope is used to connect the hinged plate and the storage rack, so that the storage rack has a certain amount of room to move when it is hinged and rotated relative to the trailer frame through the hinged plate, avoiding the arc guide rail on the storage rack from getting stuck relative to the guide wheel, and also providing a larger tolerance range for processing accuracy during installation and assembly.
[0018] The trailer frame has a triangular structure, including a quadrilateral base frame, two tripods arranged on two opposite sides of one group of the base frame, and a cross frame connected between the top corners of the two tripods, the hinged plate is hinged on the cross frame; the storage rack is located between the two tripods.
[0019] The triangular trailer frame has a stronger overall structural strength and better stability.
[0020] The beneficial effects of the utility model are:
[0021] Compared with the existing technology, the self-balancing storage rack structure for the track machine of the utility model can rotate the storage rack relative to the trailer frame through the hinged suspension mechanism, so that when the trailer frame tilts, the storage rack can still be kept in an upright state, protecting the agricultural products in the storage rack from rolling down; and in order to ensure the certainty of the rotation of the storage rack, we have added arc guide rails and guide wheels, so that the storage rack can be kept in a more stable and stationary state when it remains vertical; and in order to avoid the situation where the arc guide rail is separated from the guide wheel when the trailer frame tilts too much during operation, we have added limit blocks, thereby greatly improving safety.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:
[0027] See also Figures 1 to 4 The utility model provides a self-balancing storage rack structure for a rail machine, which is arranged as a whole on a trailer frame 1. The trailer frame 1 is a triangular structure, including a quadrilateral base frame 2, two tripods 3 arranged on both sides of one group of opposite sides of the base frame 2, and a cross frame 4 connected between the top corners of the two tripods 3; the trailer frame 1 is driven by a tractor, and the trailer frame 1 is mounted on a guide rail 5, and is connected and moved with the guide rail 5 through a plurality of guide wheels 6.
[0028] The self-balancing storage rack structure for the track machine includes a storage rack 7, which is located between the two tripods 3, and the top of the storage rack 7 is set on the trailer frame 1 through a hinged suspension mechanism. In this way, the storage rack 7 is always in a vertical state relative to the trailer frame 1 due to its own gravity. In order to keep the storage rack 7 stable, we have added an arc guide rail 8 and a guide wheel 9. The arc guide rail 8 is installed at the bottom of the storage rack 7, and the guide wheel 9 is installed on the trailer frame 1. The guide wheel 9 is in contact with the arc guide rail 8, thereby playing a guiding role. Of course, we can also install the arc guide rail 8 on the trailer frame 1 and the guide wheel 9 at the bottom of the storage rack 7, which can also achieve the same effect. However, from the perspective of economic effectiveness, the first solution is better.
[0029] The matching of the arc guide rail 8 and the guide wheel 9 enables the storage rack 7 to maintain a vertical state with directionality, avoiding the phenomenon of shaking around.
[0030] With the functions of the arc guide rail 8 and the guide wheel 9, we can design the articulated suspension mechanism to include a hinge plate 10 and a suspension rope 11. The hinge plate 10 is connected to the cross frame 4 of the trailer frame 1 through a hinge shaft 12, and four suspension holes 13 are provided on the hinge plate 10. The four suspension holes 13 correspond to the four connecting corners 14 of the storage rack 7 one by one, and the corresponding suspension holes 13 and the connecting corners 14 are connected together through the suspension rope 11.
[0031] A suspension rope 11 is used to connect the hinge plate 10 and the storage rack 7, so that the storage rack 7 has a certain amount of room to move when it is hinged and rotated relative to the trailer frame 1 through the hinge plate 10, thereby preventing the circular arc guide rail 8 on the storage rack 7 from getting stuck relative to the guide wheel 9, and also providing a larger tolerance range for processing accuracy for installation and assembly, thereby indirectly reducing manufacturing costs.
[0032] Since the storage rack 7 is often fully loaded with items during actual use, the storage rack 7 will sink relative to the trailer frame 1 (that is, it will decrease in height). The weight of the storage rack 7 plus the items will cause the arc guide rail 8 to squeeze the guide wheel 9, which makes it difficult for the storage rack 7 to rotate in a self-balanced manner with gravity. Therefore, a shock-absorbing mechanism is set between the guide wheel 9 and the trailer frame 1. The shock-absorbing mechanism not only has a buffering ability for the downward force of the storage rack (because the trailer frame will always be bumpy during operation, which causes the arc guide rail 8 of the storage rack 7 to have an impact force on the guide wheel 9), but also ensures that the friction between the arc guide rail 8 and the guide wheel 9 always remains in a relatively appropriate state, avoiding the situation where the arc guide rail 8 cannot move relative to the guide wheel 9.
[0033] Specifically, the shock-absorbing mechanism includes a wheel seat 15 fixed to the wheel axle of the guide wheel 9, a limit plate 16 arranged at the bottom of the wheel seat 15, and a pin 17 arranged at the bottom of the limit plate 16. The pin 17 is sleeved with a spring 18 and inserted into the pin hole 19 of the trailer frame 1, and the pin 17 also has an external thread. By screwing a nut 20 on the external thread, the pin 17 is always in the pin hole 19; the guide wheel 9 not only guides the arc guide rail 8, but also supports it; there is a certain gap between the limit plate 16 and the trailer frame 1, and this gap is the protection space for the elastic performance of the spring. When the gravity of the storage rack 7 is too large, the elastic performance of the spring 18 will fail and lose its effectiveness. Therefore, in this case, the limit plate 16 is directly attached to the trailer frame 1, preventing the storage rack 7 from continuing to apply pressure to the spring 18, thereby protecting the rebound force of the spring 18.
[0034] In actual application, the slope may be particularly steep, which causes the posture of the track machine to become steeper during operation. In this case, the angle of the storage rack 7 relative to the trailer frame 1 will be larger. Since the circumference of the arc guide rail 8 is limited, in order to avoid the arc guide rail 8 from detaching from the guide wheel 9, we have set limit blocks 21 at both ends of the storage rack 7. When the storage rack 7 rotates around the hinge shaft 12, the arc guide rail 8 slides over the guide wheel 9, and the limit blocks 21 prevent the arc guide rail 8 from detaching from the guide wheel 9.
[0035] Of course, the limiting block 21 is screwed to the mounting plate 22 , and the mounting plate 22 is provided on the storage rack 7 .
[0036] In order to increase the storage space of the storage rack 7 and improve transportation efficiency, we divide the storage rack 7 into two layers, including a large storage basket 23 and a small storage basket 24. The arc guide rail 8 is fixed on the large storage basket 23, and the small storage basket 24 is located in the space between the large storage basket 23 and the arc guide rail 8.
[0037] In summary, the self-balancing storage rack structure for the track machine of the present invention can always maintain a vertical state through its own gravity, preventing the crops in the storage rack 7 from rolling down. Moreover, the vertical state maintained by the storage rack 7 is close to a static state, which further protects the crops from bumps and collisions. The newly added shock-absorbing mechanism can also provide the storage rack 7 with a certain buffering capacity, further reducing bumps, while also ensuring the effectiveness of the automatic rotation of the storage rack 7 to maintain a vertical state.
[0038] The above is a detailed introduction to the self-balancing storage rack structure for track machines provided by the embodiment of the present invention. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the technical solutions disclosed by the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation of the present invention.
