Detailed Description

The following detailed description will be given with reference to specific embodiments, so as to solve the technical problems by applying technical means, and to fully understand and implement the technical effects of the present invention.

Referring to fig. 1, 2, 3 and 4, a transportation tractor includes a tractor body 1 and a tractor 2 mounted on the tractor body 1, a front wheel set 3 and a rear wheel set 4 are mounted at a lower end of the tractor body 1, a transmission assembly 5 for driving and connecting the front wheel set 3 and the rear wheel set 4 is disposed at a lower end of the tractor body 1, the transmission assembly 5 includes two sets of mounting structures disposed on a lower surface of the tractor body 1 for respectively mounting the front wheel set 3 and the rear wheel set 4, each of the mounting structures includes a fixed base 51, a rotating base 52 disposed on the fixed base 51, and a transmission sprocket 53 disposed on the rotating base 52, the front wheel set 3 and the rear wheel set 4 are respectively mounted on the rotating base 52 and can rotate therewith, structurally, the tractor body 1 includes a frame 11 and two pairs of vehicle plates 12 symmetrically mounted on the frame 11, and the two sets of mounting structures of the transmission assembly 5 are respectively mounted on the two vehicle plates 12; this is the specific mounting structure of the present embodiment, it should be understood that, when necessary, the structure of the frame body 11 may also be changed, and two sets of mounting structures are disposed on the frame body 11; since the vehicle body 12 is often made of a wooden plate, it is easily damaged, and thus, when the vehicle body 12 needs to be replaced, it can be replaced without changing the mounting structure of the transmission assembly 5.

Structurally, the transmission chain wheels 53 on the two mounting structures are connected with each other through a transmission chain assembly, the transmission chain assembly comprises chain bodies 54 which are mounted on the transmission chain wheels 53 in a matching manner and connecting pieces 55 which connect the head ends and the tail ends of the two chain bodies 54, and the connecting pieces 55 enable the head ends and the tail ends of the two chain bodies 54 to be connected in a crossed manner; the cross-type connection described herein specifically means that the connector 55 includes a first connecting piece 551 and a second connecting piece 552 which are symmetrically arranged, the second connecting piece 552 is composed of two laminated pieces 552a, the first connecting piece 551 is inserted between the two pieces 552a, and the first connecting piece 551 is not in contact with the two pieces 552 a. The structure of the two-layer lamination 552a of the second connecting piece 552 is to ensure that the transmission chain assembly does not interfere with the two side chain bodies 54 during transmission, thereby ensuring smooth transmission operation.

According to the technical scheme, the mounting structures of the front wheel set 3 and the rear wheel set 4 are improved, the traction piece 2 is pulled as required, so that the front wheel set 3 integrally rotates on the rotating seat 52, and further the integral steering of the vehicle body 1 is realized, the process is stable and smooth, the traction is convenient, and the vehicle can be directly steered when the tractor is used according to the road condition and the traveling route of a workshop easily;

structurally, the front wheel set 3 and the rear wheel set 4 are linked through the transmission assembly 5, when the front wheel set 3 turns, the rear wheel set 4 can rotate oppositely, and then when the vehicle body 1 turns, the rear wheel set 4 is adjusted towards the direction, so that the smoothness during turning is further improved;

compared with a single-direction wheel or a universal wheel on a traditional plate trailer, the synchronous transmission assembly 5 has the advantages that the sizes of the front wheel set 3 and the rear wheel set 4 can be larger, so that the bearing capacity of the tractor can be increased, and the synchronous transmission assembly is more suitable for transporting large-mass materials related to stone materials or similar fields where the tractor is located.

In this embodiment, the traction element 2 is a pull rope, and two ends of the pull rope are connected to two ends of the axle of the front wheel set 3. When the tractor is used, the structure of the pull rope can directly apply force to the axle of the front wheel set 3, so that the angle of the front wheel set during traveling is changed to finish steering, and the force application mode during steering is direct.

On the other hand, the towing member 2 may be a metal handle, and the handle is fixed to the vehicle body 1. Under this kind of structure, when needs turn to, the accessible handle is exerted pulling force to one side of automobile body 1, and corresponding rotation is realized to front wheel group 3 and rear wheel group 4 under the stress condition, and then accomplishes and turn to, and this kind of structure is more favorable to user's application of force, but turns to the process and then is not direct enough for the stay cord, is another concrete implementation structure.

Meanwhile, in use, the vehicle body 1 is provided with a hook 13 for connecting a plurality of tractors conveniently; under the structure, the head-to-tail connection and transportation of a plurality of tractors can be realized, a use form of dragging a plurality of groups of materials at one time is formed, and the transportation efficiency is improved; the traditional structure needs to embed a corresponding transmission track in the workshop ground, but the concrete structure of the track can be omitted in the embodiment, and the effect of the mechanism can be achieved by changing the tractor body 1.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
