Based on the spirit of this utility model, any other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of this utility model.

[0024] like Figure 1-3 As shown, this utility model provides a gravity-driven automatic unloading turnover vehicle based on a mechanical stopper, including: a vehicle body 1, a carrier 2, a guide rail and a mechanical stopper 4;

[0025] like Figure 1 As shown, the vehicle body 1 includes: a support frame 11 and a platform 12; at least one platform 12 is provided in the internal space enclosed by a plurality of support frames 11, and each corner of the platform 12 is mounted on the support frame 11. In one embodiment, there are four support frames 11 and two platform 12s; the platform 12 is provided with a plurality of rolling elements 121 for sliding materials, and the platform 12 is inclined.

[0026] In another embodiment, there are six support frames 11, which can provide better support when the carrier 2 or the material is too heavy.

[0027] The support frame 11 has several placement holes. Each corner of the platform 12 can be placed in different placement holes to achieve different tilt angles. The tilt angle of the platform 12 is determined by the actual material characteristics and feeding requirements.

[0028] The vehicle body 1 is made of high-strength steel, which has good load-bearing capacity and stability. The bottom of the vehicle body 1 is equipped with casters 13, which facilitates the movement and turning of the turnover vehicle. The frame structure of the vehicle body 1 is reasonably designed and can effectively support the carrier and other components. The movement of the vehicle body 1 is not limited to manual pushing, but can also be carried out by robots such as AGVs.

[0029] The carrier 2 is placed on the platform 12. Under the action of gravity, the carrier 2 slides along the rolling element 121 or the track. The carrier 2 is used to carry different products and semi-finished products. Its sides and bottom are made of wear-resistant materials to extend its service life.

[0030] The guide rail is mounted on the platform 12 and is parallel to the inclined surface of the platform 12. The guide rail surface is smooth to reduce friction between the material or carrier and the guide rail. Limit devices are provided at both ends of the guide rail to prevent the material or carrier from falling off the guide rail during the downward slide. The position of the guide rail can be adjusted according to the size of different carriers or products.

[0031] Mechanical stopper 4 is installed at one end of platform 12; mechanical stopper 4 includes: stop rod 41, connecting rod 42 and push rod 43; stop rod 41 is placed in stop rod slide 44, stop rod 41 can move along the inner wall of stop rod slide 44, the bottom end of the inner side of stop rod slide 44 is fixedly connected to one end of spring 45, the other end of spring 45 is fixedly connected to the bottom of stop rod 41, the other end of stop rod 41 is fixedly connected to the side of the track near the track with an anti-impact roller 47, push rod slide 46 is vertically fixedly connected to stop rod slide 44, and push rod 43 is placed in the push rod Inside the slide 46, the push rod 43 can move along the inner wall of the push rod slide 46. A first elongated groove is opened on one side of the push rod slide 46, and a second elongated groove is opened on the same side of the blocking rod slide 44. The connecting rod 42 is located outside the first and second elongated grooves. Connectors are provided at both ends of the connecting rod 42. The connector at one end of the connecting rod 42 passes through the first elongated groove and is rotatably connected to the end of the push rod 43 away from the outlet of the push rod slide. The connector at the other end of the connecting rod 42 passes through the second elongated groove and is rotatably connected to the end of the blocking rod 41 away from the outlet of the blocking rod slide.

[0032] Working principle:

[0033] When the push rod 43 of the turnover vehicle does not collide with the blocking surface 5, the top of the blocking rod 41 extends out of the blocking rod slide 44, and the material or carrier 2 is blocked on the guide rail.

[0034] When the turnover cart reaches the designated position and needs to be unloaded, the push rod 43 will hit the blocking surface 5, and the collision force will force the push rod 43 to move horizontally.

[0035] The push rod 43 drives one end of the connecting rod 42 to move in the first elongated groove on the push rod slide 46;

[0036] The other end of the connecting rod 42 moves in the second elongated groove on the blocking rod slide 44;

[0037] The connecting rod 42 drives the blocking rod 41 to move downward against the elastic force of the spring 45. When the blocking rod 41 moves to the bottom, the horizontal section of the top of the anti-impact roller 47 is parallel to the guide rail.

[0038] The material or carrier 2 flows out automatically along the guide rail under the action of gravity, realizing automatic unloading.

[0039] The trolley leaves the designated position, the push rod 43 leaves the blocking surface 5, the blocking rod 41 rebounds under the elastic force of the spring 45, and the mechanical blocker 4 returns to its initial state.

[0040] The mechanical stopper 4 converts horizontal motion into vertical motion by applying horizontal force.

[0041] Compared with the prior art, the beneficial effects of this utility model include at least the following:

[0042] 1. Improve unloading efficiency: This application designs a mechanical stopper that uses gravity for automatic feeding, eliminating the need for manual handling and greatly improving the feeding speed, saving time and labor costs.

[0043] 2. Simple structure and low cost: Compared with the unloading using active power, the turnover vehicle structure of this utility model has a simple structure, the main components are made of common materials, the cost is low, and it is easy to promote and apply.

[0044] 3. High applicability: By replacing different carriers and adjusting the position of the guide rails, it can be applied to the turnover of various types and shapes of materials, and has strong versatility.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model.
