Description

Technical Field

[0001] The utility model relates to the technical field of spraying equipment, in particular to a spraying machine. Background Art

[0002] The sprayer is used to survey and map road traffic safety signs such as zebra crossings, sidewalks, lanes and other road signs on roads and other roads. It adopts a rear-wheel drive system, in which the motor is placed at the rear axle. Since the sprayer needs to be transferred to different positions for line marking spraying, the overall quality becomes a key indicator. Since the rear axle is composed of two half-bridges, the half-bridge differential motion is implemented and driven by the motor to achieve synchronous drive of the two rear wheels and cooperate with the front wheel to achieve straight forward movement. However, the overall mass of the rear axle is heavy, which has become a key indicator restricting weight reduction. To this end, we propose a sprayer. Utility Model Content

[0025] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Refer to the attached Figure 1-4, a spraying machine, which adopts more than three wheels, the front wheel is an odd number, in order to reduce weight and save costs, the rear axle is cancelled, and only one motor is used to drive one of the rear wheels, which will cause the spraying machine to be unable to move in a straight line, including a bottom plate 1, a turntable 2 and a locking mechanism are installed on the bottom of the bottom plate 1, the turntable 2 is rotatably arranged on the bottom plate 1 through a rotating shaft, a wheel frame 3 is installed on the turntable 2, and the wheel frame 3 is connected to the front wheel, and a notch 32 is opened on the turntable 2 along its radial direction, the outer size of the notch 32 is larger than the inner size of the notch 32, so as to facilitate the entry of the locking mechanism to lock it and realize straight-line travel. This application adopts a method of having only one motor to drive a single rear wheel to reduce the overall quality, but driving only a single rear wheel will cause the vehicle to be unable to move straight;

[0027] The locking mechanism includes a clamp 4, a positioning shaft 41, and a torsion spring 42. The clamp 4 is installed on one side of the turntable 2, and the positioning shaft 41 is inserted into the clamp 4 and fixed on the bottom plate 1 so that it rotates along the positioning shaft 41 as the center of a circle. The positioning shaft 41 is sleeved with a torsion spring 42, one end of the torsion spring 42 is fixed on the bottom plate 1, and the other end is fixed on the clamp 4;

[0028] Furthermore, the clamp 4 is in the shape of an elongated strip, and the head end of the clamp 4 has a flange extending toward the notch 32 for clamping with the notch 32, the positioning shaft 41 is inserted in the middle of the clamp 4, and the tail end of the clamp 4 is also connected to a cross plate 43, the cross plate 43 is provided with a mounting hole 44 for connecting a rope, the rope extends to the handle of the sprayer, and the handle is squeezed so that the rope pulls the clamp 4 to rotate clockwise, at this time, the flange at the head end of the clamp 4 disengages from the notch 32, the turntable 2 can rotate direction, so that the sprayer can change direction, conversely, the flange at the head end of the clamp 4 is abutted against the notch 32, at this time, the direction of the turntable 2 is locked, and after locking, the sprayer moves in a straight line.

[0029] In this embodiment, the turntable 2 is rotatably set on the base plate 1, a fixing hole 21 is opened on the turntable 2, and a waist hole 31 is opened on the wheel frame 3. The curvature of the opening is consistent with the curvature of the turntable 2, and the fixing hole 21 corresponds to the waist hole 31. The direction of the wheel frame 3 can be fixed and fine-tuned by bolts. When the locking mechanism is locked with the turntable 2, the direction of the front wheel is fine-tuned and fixed through the waist hole 31, so that it can travel in a straight line.
