The present invention will be further described in detail with reference to the accompanying drawings, in which

As shown in FIG. 1, the present invention discloses an automobile capable of automatically loading and unloading bulk materials. The automobile first has a conventional loading box, which is disposed on a frame of the automobile, and the loading and unloading box is close to One end of the tail is hinged to the frame, and one end of the front (ie, the cockpit) is connected to the frame by a first set of hydraulic cylinders. FIG. 1 shows that when the first group of hydraulic cylinders are in the extended state, the side of the loading box close to the cockpit is tilted up, and after the lifting, the entire loading box is tilted, in the loading box Under the action of gravity, the bulk material slides down the bottom plate of the box, thereby sliding down to the ground, realizing the unloading operation. An operating handle is provided in the cockpit, and the operating handle is connected with a valve between the hydraulic cylinder and the hydraulic pump. The driver adjusts the valve by operating the operating handle. The valve can be a steering valve, thereby controlling the hydraulic pump and the hydraulic pressure. The connection status between the cylinders. When the hydraulic pump is connected to the hydraulic cylinder, it can drive the hydraulic cylinder to extend or retract. The present invention also includes a bucket, as shown in Figures 1 and 2, which spans the loading bin and is hinged to the frame by hinges on both sides, and the bucket and the frame are A second group of hydraulic cylinders is disposed therebetween, and the bucket is rotated up and down with respect to the hinge by the second group of hydraulic cylinders. A bucket and a second set of hydraulic cylinders are shown in Figures 1 and 2. Usually, the first group of hydraulic cylinders are two, distributed on both sides of the loading box, which ensures that the support of the loading box is relatively stable. Similarly, there are usually two hydraulic cylinders in the second group, distributed on both sides of the bucket, and the cylinder side of the hydraulic cylinder is fixed on the loading box (eg Figure 2) can also be fixed on the frame. The piston side of the second set of hydraulic cylinders is fixed to the bucket. The hydraulic cylinder is driven by the hydraulic pump to make the piston of the second group of hydraulic cylinders expand and contract, thereby driving the bucket up and down. Wherein, when the bucket is rotated upward by the second group of hydraulic cylinders, all the materials in the production surface of the bucket naturally slide into the loading box. That is to say, the setting position of the bucket is such that the material in the bucket can fall into the loading box under the action of natural gravity. The automobile capable of automatically loading and unloading bulk material further includes: a hydraulic oil pump, wherein the hydraulic oil pump communicates with the first group of hydraulic oil cylinders and the second group of hydraulic oil cylinders through a pipeline, and is on the pipeline A steering valve is provided. And further comprising: a joystick disposed in a cockpit of the automobile, and the joystick is coupled to the steering valve to control the steering valve to achieve communication between the hydraulic oil pump and the first group of hydraulic cylinders Or implementing the hydraulic oil pump to communicate with the second group of hydraulic cylinders; or implementing the hydraulic oil pump and the first group and the second group of hydraulic cylinders are not in communication. That is, the driver controls the steering valve by manipulating the joystick in the cockpit. As shown in FIG. 3, two kinds of joysticks are shown in FIG. 3, one is a car handle, that is, a joystick for controlling the extension and retraction of the piston rods in the first group of hydraulic cylinders on the loading box; The other is the bucket joystick, which is the operating handle that controls the extension and retraction of the piston rod in the second set of hydraulic cylinders on the bucket. So, how does the operating handle control the extension and retraction of the hydraulic cylinder? In the actual design, it is mainly through adjusting the connection relationship between the hydraulic oil pump and the hydraulic cylinder. When the hydraulic oil pump communicates with the hydraulic cylinder, the hydraulic oil pump supplies hydraulic oil to the hydraulic cylinder, which promotes the extension of the piston rod in the hydraulic cylinder. Therefore, in fact, the compartment operating handle and the bucket operating handle can be designed as one handle, which is the operating handle. The different gear positions of this operating handle correspond to different steering positions of the steering valve between the hydraulic oil pump and the hydraulic cylinder. And the first group of hydraulic oil The cylinder and the second group of hydraulic cylinders are connected to a hydraulic oil pump, that is, a hydraulic oil pump can supply hydraulic oil to the two sets of hydraulic cylinders, so that which group of hydraulic cylinders need to be delivered, the steering valve is adjusted. When the steering valve is turned to turn on the hydraulic oil pump and the first group of hydraulic cylinders, the side of the loading box close to the cockpit is lifted, and the unloading operation is realized at this time; when the steering valve is turned to the hydraulic oil pump and the second When the hydraulic cylinder is set, as the piston of the second group of hydraulic cylinders is extended, the bucket is lowered, the driver reverses backwards at the same time, and the bulk material is shoveled into the bucket. At this time, the driver manipulates the joystick. The control steering valve blocks the communication relationship between the hydraulic oil pump and the second group of hydraulic cylinders. As the piston of the second group of hydraulic cylinders is shortened, the bucket is lifted, and the bulk material is smoothly slipped into the loading box. Loading operation. As shown in FIG. 4, the automobile capable of automatically loading and unloading bulk material further includes: a pair of supporting outer plates 3 (only one is shown in FIG. 4) disposed on the outer side of the frame 1 of the automobile And located inside the drive wheel 10 (shown in Figure 5). Also included is a pair of support inner panels 8 as shown in FIG. 5, which are respectively disposed inside the frame 1 of the automobile corresponding to one support outer panel 3, and are also located inside the drive wheel 10. The ear supports 7 are disposed on the outer sides of the support outer plates 3, and the two sides of the bucket are respectively pivotally fixed to the ear blocks 7. The ear seat 7 may be disposed directly on the support outer panel 3 or may protrude from the support outer panel 3. As shown in FIG. 5, the position of the ear mount 7 can protrude from the boundary of the support outer panel 3, and can even protrude from the position of the drive wheel 10. In Fig. 4, the support outer panel 3 is shown fixed to the frame 1 by means of a connector, such as a screw 2. The support inner panel 8 can also be fixed to the frame 1 by screws. The automobile capable of automatically loading and unloading bulk material further comprises: a connecting plate 6 (shown in FIG. 5) disposed between each pair of corresponding supporting outer plates 3 and supporting inner plates 8, said supporting outer plates 3 and the bottom of the support inner panel 8 are connected together by the connecting plate 6, and the drive axle 9 of the automobile passes through the cavity formed by the connecting plate 6, the supporting outer panel 3 and the supporting inner panel 8, ie The web 6 is located below the transaxle 9 of the motor vehicle. Inside the support Both the plate 8 and the connecting plate 6 have support and reinforcement for the supporting outer plate 3.

The automobile capable of automatically loading and unloading bulk material further includes: a limiting frame disposed on the frame and surrounding the driving axle 9 of the automobile, and a lateral dimension of the limiting frame Less than the vertical dimension. The limit bracket is shown in Figure 4 as a box-shaped structure above the web. The purpose of the lateral dimension of the stop frame being less than the vertical dimension is to limit the forward and backward movement of the transaxle 9. In the process of the bucket being lowered and lifted, since the bucket is connected to the support outer panel, and the support outer panel is fixed to the frame 1, the bucket will exert a certain effect on the frame 1 after being loaded. force. The transaxle 9 is also fixed to the frame 1, and therefore also exerts a certain force on the transaxle 9. Thus, the drive axle 9 may be displaced. On the other hand, if the transaxle 9 is displaced in the front-rear direction, fatigue is likely to be damaged, and if the transaxle 9 is displaced in the up-and-down direction, it can be partially reduced by the damping effect of the vibration-damping steel plate 4. Therefore, the present invention contemplates a limit stop for limiting the forward and backward displacement amplitude of the transaxle 9.
