Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of agricultural machinery accessories and relates to a splicing track for agricultural vehicles to travel. Background Art
[0002] Agricultural vehicles (such as earthmoving machines, etc.) generally need to travel in the fields, but the soil in the fields is usually soft and uneven, which is not suitable for the travel needs of agricultural vehicles. Therefore, in order for agricultural vehicles to travel smoothly, tracks need to be laid in the fields. The tracks of agricultural vehicles generally include a pair of parallel guide rails and track plates connecting the guide rails. When in use, the wheels of the agricultural vehicle fit on the guide rails and travel along the guide rails. Due to production and transportation restrictions, the length of the track is generally limited. When the driving distance is long, multiple tracks need to be used. In actual use, there is often a gap between the tracks laid together, and when the agricultural vehicle travels to the end of the track, the section of the track will also tilt upwards. After multiple driving, the track is also prone to shifting. These defects will seriously affect the driving of agricultural vehicles. In view of this, it is necessary to develop a new track structure to overcome these defects. Utility Model Content

DETAILED DESCRIPTION
[0022] The present invention will be further described below with reference to the accompanying drawings. Figure 1-6 :
[0023] A spliced track for agricultural vehicles, comprising a plurality of track units spliced end to end into a continuous track, wherein the track unit comprises a pair of parallel guide rails 1 and a track plate 2 connecting the guide rails 1, and the two ends of the track unit are respectively provided with a first spliced end 3 and a second spliced end 4, wherein the first spliced end 3 comprises a slot 31 corresponding to the guide rail 1 and an upper spliced plate 32 corresponding to the track plate 2, and the second spliced end 4 comprises an insert block 41 corresponding to the guide rail 1 and a lower spliced plate 42 corresponding to the track plate 2, wherein the insert block 41 and the slot 31 form an inserted splicing structure, and the upper splicing plate 32 and the lower splicing plate 42 form a splicing structure stacked up and down.
[0024] The use method of this embodiment is: splice the second splicing end 4 of the first track unit with the first splicing end 3 of the second track unit, splice the second splicing end 4 of the second track unit with the first splicing end 3 of the third track unit, splice the second splicing end 4 of the fourth track unit with the first splicing end 3 of the third track unit... After splicing in sequence, a complete track structure is formed. After splicing, the plug block 41 is plugged into the slot 31 to form a splicing structure corresponding to the guide rail 1, and the upper splicing plate 32 and the lower splicing plate 42 form a splicing structure corresponding to the track plate 2.
[0025] In order to make the spliced track form a whole, the upper surface of the first spliced end 3 is the same surface as the upper surface of the track unit, the upper surface of the second spliced end 4 is lower than the upper surface of the track unit, and the bottom is flush with the bottom of the track unit; the upper surface includes the planar upper surface of the track plate 2 and the arc-shaped upper surface of the guide rail 1.
[0026] The rail plate 2 is a hollow plate, and the upper splicing plate 32 and the lower splicing plate 42 are non-hollow plates; further, the rail plate 2 includes a hollow plate formed by staggered arrangement of transverse plates, longitudinal plates and inclined plates.
[0027] In this embodiment, the specific structure of the plug block 41 and the slot 31 is: the slot 31 is set at the bottom of the guide rail 1, the plug block 41 has the same shape as the guide rail 1 and is reduced in size, and the outer wall of the plug block 41 is in contact and connected with the inner wall of the slot 31 after splicing. By setting the above structure, after the track unit is spliced, the guide rail 1 part can form a continuous integral structure, and the splicing structure can also be made more solid.
[0028] Furthermore, a limiting groove 43 is provided on the inner side of the insert block 41, and a limiting block 33 is provided on the outer side of the slot 31. After splicing, the limiting block 33 is inserted into the limiting groove 43 to form a limiting structure in the horizontal direction; by providing the limiting groove 43 and the limiting block 33, adjacent track units can form a hooking structure to prevent them from falling out in the horizontal direction.
[0029] In order to further prevent the splicing structure from falling off or shifting, a locking structure is arranged between the upper splicing plate 32 and the lower splicing plate 42, and both ends of the locking structure do not exceed the plane where the track plate 2 is located; the locking structure can adopt the locking structure commonly used in the field, such as matching bolts and nuts or matching blocks and slots; through the locking structure, adjacent track units can be fastened and connected.
[0030] In this embodiment, the locking structure includes a locking knob 5, a first locking groove 34 arranged on the first splicing end 3, and a second locking groove 44 arranged on the second splicing end 4. The locking knob 5 includes a knob 51 and a rotating shaft 53 with locking protrusions 52 formed on both sides. The first locking groove 34 and the second locking groove 44 are provided with through holes adapted to the rotating shaft 53. The locking knob 5 rotates between a locked position and an unlocked position. When in use, the rotating shaft 53 is aligned with the first locking groove 34 and the second locking groove 44 and inserted. At this time, the locking knob 5 is in the unlocking position. Then the locking knob 5 is rotated 90 degrees. At this time, the locking knob 5 is in the locking position. Since the through hole shape on the first locking groove 34 and the second locking groove 44 is adapted to the rotating shaft 53, the locking protrusion 52 is rotated from the through hole position to the non-through hole position. The locking protrusion 52 forms a resistance structure with the bottom of the second locking groove 44 to prevent it from coming out. Therefore, the locking knob 5 in the locked position fastens the two track units together. In this embodiment, two locking knobs 5 are correspondingly provided for each track unit.
[0031] Preferably, a receiving groove 35 for accommodating the knob 51 is provided at the upper end of the first locking groove 34, and the receiving groove 35 can prevent the upper surface of the knob 51 from exceeding the upper surface of the rail plate 2; a corner limit block 45 for limiting the rotation angle of the locking knob 5 is provided at the bottom of the second locking groove 44, and two corner limit blocks 45 are staggered. When the rotating shaft 53 is located in the unlocking position and the locking position, the two side surfaces of the locking protrusion 52 respectively contact therewith, and the corner limit block 45 limits the rotation angle of the rotating shaft 53 between the unlocking position and the locking position.
[0032] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
