Description

Technical Field:

[0001] This application relates to the technical field of unloading trucks, and particularly to a heavy-duty unloading truck. Background Art:

[0002] The belt conveyor unloading trolley is a separate component of the belt conveyor and is mainly used in occasions where there is a requirement for unloading the belt conveyor. Its function is the same as that of the unloader, but it can achieve multi-point and different-location material distribution. Light-duty unloading trolleys are suitable for materials with a bulk density < 1600 kg / m 3 ; heavy-duty unloading trolleys are suitable for materials with a bulk density ≥ 1600 kg / m 3 .

[0003] The utility model patent with the application number CN201620288219.0 - a heavy-duty unloading truck, which is characterized in that it includes a vehicle frame. The vehicle frame is composed of a support base, a support frame, and a belt guiding frame. The support base is vertically arranged. The support frame is horizontally arranged and fixed in the middle of the support base. The support frame is a double-layer steel plate structure, and a wire mesh is filled in the support frame. A first drive wheel set is installed on the support frame. The first drive wheel set is connected to the output shaft of a speed reducer, and the speed reducer is fixed on the support frame. A drive belt is sleeved on the first drive wheel set. After passing around the first drive wheel set, the drive belt is connected to a redirecting roller set. The redirecting roller set is arranged above the first drive wheel set. The redirecting roller set is installed on a positioning frame. The positioning frame is a horizontally arranged steel plate structure and is fixed on the support base. A second drive wheel set is installed on the belt guiding frame. After passing around the redirecting roller set, the drive belt is connected to the second drive wheel set. After passing around the second drive wheel set, the drive belt is sequentially connected to troughing idlers arranged on the belt guiding frame. A hopper is also provided on the left side close to the second drive wheel set. The hopper is fixed on the support base, and the discharge port of the hopper is aligned with the drive belt on the second drive wheel set.

[0004] Since the second drive wheel set of the heavy-duty unloading truck needs to have a certain height to achieve unloading, when the belt turns from the horizontal section to the inclined section, due to the relatively high height at the tail of the unloading truck body, and the concave arc of the belt becomes smaller at the turning point due to the tension, a straight section as shown in Figure 4 will appear, which will cause some materials to spill and affect production and transportation.

[0026] To make the purpose, technical solution and advantages of the implementation of the present utility model clearer, the present utility model will now be further described in detail with reference to the accompanying drawings and the following embodiments, so that the public can better master the implementation method of the present utility model. The specific implementation scheme of the present utility model is as follows:

[0027] A heavy-duty unloading truck includes an unloading truck body 1. A mobile trolley 2 is connected to the right side of the unloading truck body 1. A plurality of troughed idlers 3 are arranged on the upper end surface of the mobile trolley 2. The plurality of troughed idlers 3 are arranged at intervals side by side along the running direction of the mobile trolley 2, and the troughed idlers 3 from left to right are arranged from high to low in sequence, with a slow support transition. The first support 4 and the second support 5 are respectively arranged on the upper end surface of the mobile trolley 2 in a fixed structure manner. The first support 4 is provided with a first pressure wheel 6 in a rotating structure manner. The two first pressure wheels 6 are symmetrically arranged above the first troughed idler 3 on the left side to press both sides of the tape against the upper end surface of the first troughed idler 3 on the left side; the second support 5 is provided with a second pressure wheel 7 in a rotating structure manner. The two second pressure wheels 7 are symmetrically arranged above the first troughed idler 3 on the left side to press both sides of the tape against the upper end surface of the first troughed idler 3 on the right side. Troughed idlers are arranged on the mobile trolley to support the tape at the turning point, and cooperate with the first pressure wheel and the second pressure wheel to press the tape on the upper part of the mobile trolley, ensuring that it is in a concave structure, avoiding material spillage, and improving the stability of conveying.

[0028] Further, the height of the mobile trolley 2 is less than 10 cm. The mobile trolley 2 includes a vehicle frame, and two sets of wheel pairs are arranged on both sides of the vehicle frame in a rotating structure manner, reducing the height of the upper end surface of the lowest troughed idler 3 to transition with the lower conveying frame.

[0029] It should be noted that both the first support 4 and the second support 5 are arranged in an inverted U-shaped frame structure. A reinforcing brace 10 for connecting the mobile trolley 2 is provided on one side of each of the first support 4 and the second support 5, which neither interferes with the material transportation on the lower conveyor belt nor affects the structural stability.

[0030] Specifically, rotating shafts 9 are sleeved inside the first pressing wheel 6 and the second pressing wheel 7 in a fixed structure manner. The rotating shafts 9 are respectively connected to the first support 4 and the second support 5 in a rotational structure manner. Bearing seats are connected to both sides of the rotating shafts 9 by keys, and the bearing seats are connected to the first support 4 and the second support 5 in a fixed structure manner. It should be noted that the pressing wheels avoid the middle position of the belt and do not interfere with the material.

[0031] It should be elaborated that inclined arc surfaces 8 parallel to the inclined rollers of the troughing idler 3 are provided on the outer edges of the first pressing wheel 6 and the second pressing wheel 7. By setting the inclined arc surfaces parallel to the inclined rollers, the contact area is increased, the pressing wheels fit better with the belt, and damage to the belt by the edges of the pressing wheels can be avoided, thus improving the service life of the belt.

[0032] The working principle and process of the present utility model are as follows:

[0033] The unloading vehicle body 1 drives the mobile trolley 2 to a predetermined position, and the belt is started for transportation. When the belt carries the material past the upper part of the mobile trolley 2, both sides of the belt are pressed tightly against the inclined rollers of the troughing idler 3 by the first pressing wheel 6 and the second pressing wheel 7. Due to the self-weight of the material, the middle part of the belt is supported by the horizontal rollers of the troughing idler 3, so that the belt smoothly enters the unloading vehicle body 1 from the horizontal section.
