具体实施方式Detailed ways
下面结合附图与实施例对本发明作进一步说明。The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
如图1所示，给出了本发明的传输带式自卸货厢第1种实施例的结构示意图，其由车厢1、前带轴2、后带轴3和传输带4组成，车厢1用于存储货物或物料，前带轴2和后带轴3分别转动设置于车厢1的前端和后端，前带轴2、后带轴3均连接有驱使其转动的动力装置，动力装置可采用液压马达。传输带4位于车厢1的底部，以便传输带4右前向后运动的过程中，可将车厢1内的物料带出。传输带4的前端固定并缠绕于前带轴2上，传输带4的后端固定并缠绕于后带轴3上。As shown in Figure 1, the structure diagram of the first embodiment of the conveyor belt type self-unloading cargo compartment of the present invention is provided, which is composed of a compartment 1, a front belt shaft 2, a rear belt shaft 3 and a transmission belt 4, and the compartment 1 uses For storing goods or materials, the front belt shaft 2 and the rear belt shaft 3 are respectively rotated and arranged at the front end and the rear end of the compartment 1. The front belt shaft 2 and the rear belt shaft 3 are connected with a power device to drive them to rotate, and the power device can adopt hydraulic motor. The conveyor belt 4 is located at the bottom of the compartment 1, so that the materials in the compartment 1 can be taken out during the right front and rearward movement of the conveyor belt 4. The front end of the transmission belt 4 is fixed and wound on the front reel 2 , and the rear end of the transmission belt 4 is fixed and wound on the rear reel 3 .
装载物料之前，动力装置驱使前带轴2转动，使传输带4除了铺设于车厢1底部的部分之外，全部缠绕于前带轴2上。在需要卸物料时，动力装置驱使后带轴3转动，拉动这铺设在车厢1底部的传输带和缠绕在前带轴2上的传输带右前向后运动，进而将车厢内的物料卸出；如图4所示，给出了本发明的传输带式自卸货厢处于卸料完毕状态的结构示意图，可见，卸货完毕后，传输带除了铺设于车厢1底部的部分外，其余的部分完全缠绕在了后带轴3上。由于传输带4向前带轴2上缠绕的过程中，车厢1内没有物料，只需要很小的动力即可，因此驱使前带轴2的动力装置具有较小的扭矩即可，其可采用电机或动力较小的液压马达即可。而后带轴3驱使传输带4从前向后运动的过程中，车厢1内物料的重力全部作用于传输带4上，因此需要较大的动力，其动力装置可采用具有大扭矩输出的液压马达。Before loading materials, the power unit drives the front belt shaft 2 to rotate, so that the transmission belt 4 is all wound on the front belt shaft 2 except for the part laid on the bottom of the compartment 1 . When materials need to be unloaded, the power unit drives the rear belt shaft 3 to rotate, and pulls the transmission belt laid on the bottom of the compartment 1 and the transmission belt wound on the front belt shaft 2 to move right forward and backward, and then unload the materials in the compartment; As shown in Figure 4, the structure schematic diagram of the conveyor belt type self-unloading cargo compartment of the present invention in the state of unloading is provided. It can be seen that after the unloading is completed, the conveyor belt is completely wound except for the part laid on the bottom of the compartment 1. on the rear reel 3. Since the transmission belt 4 is wound on the front belt shaft 2, there is no material in the compartment 1, and only a small power is needed, so the power device driving the front belt shaft 2 has a small torque. An electric motor or a hydraulic motor with less power can be used. While the rear belt shaft 3 drives the transmission belt 4 to move from front to back, the gravity of the material in the compartment 1 all acts on the transmission belt 4, so a larger power is needed, and its power unit can adopt a hydraulic motor with a large torque output.
车厢1可采用横截面为V字形的车厢，或采用横截面为U字形的车厢，如图2和3所示，分别给出了本发明的传输带式自卸货厢为V字形和U字形车厢的结构示意图。V字形车厢5有利于车厢1内散装物料的完全卸出，U字形车厢6有利于存储更多的货物。Compartment 1 can adopt the compartment of V-shaped cross section, or adopt the compartment of U-shaped cross-section, as shown in Figures 2 and 3, respectively provide the conveyor belt type self-unloading cargo compartment of the present invention as V-shaped and U-shaped compartments Schematic diagram of the structure. The V-shaped compartment 5 is conducive to the complete unloading of bulk materials in the compartment 1, and the U-shaped compartment 6 is conducive to storing more goods.
如图5所示，给出了本发明的第1种传输带式自卸货厢构成的自卸车的结构示意图，其由车架7、悬架总承8、车轮9、车厢1、前带轴2、后带轴3和传输带3组成，车架7起固定和支撑作用，悬架总承8固定于车架7后端的下方，车轮9固定于悬架总承8上。车厢1设置于车架7上，车厢1内所设置的前带轴2、后带轴3和传输带4的结构，与上面所述的图1、图4中的传输带式自卸货厢的结构完全一致。As shown in Figure 5, the structural representation of the dump truck that the first kind of conveyor belt type dump truck of the present invention is formed is provided, and it is made up of vehicle frame 7, suspension assembly 8, wheel 9, compartment 1, front belt shaft 2, the rear belt shaft 3 and the transmission belt 3 are composed, the vehicle frame 7 plays a role of fixing and supporting, the suspension assembly 8 is fixed on the bottom of the vehicle frame 7 rear end, and the wheel 9 is fixed on the suspension assembly 8. Compartment 1 is arranged on the vehicle frame 7, and the structure of front tape shaft 2, rear tape shaft 3 and transmission belt 4 arranged in the compartment 1 is the same as that of the transmission belt type self-unloading cargo compartment in Fig. 1 and Fig. 4 described above. The structure is exactly the same.
由于车厢1内传输带4不可能无限长度设置，其通常为2个或2个以上的车厢长度，在后带轴3带动传输带4右前向后运动卸货的过程中，如果自卸车装载散装物料，传输带4向后运动一个车厢1的长度，不能将物料全部卸出，因此，这种车厢1更适于装载不容易塌陷的较大体积的物品，如图6所示，给出了本发明的第1种传输带式自卸货厢构成的自卸车卸货完成状态的结构示意图，较大体积的物品采用本实施例的自卸车比较容易卸出。Since the conveyor belt 4 in the compartment 1 cannot be set with an infinite length, it is usually 2 or more than 2 compartment lengths. During the unloading process when the rear belt shaft 3 drives the conveyor belt 4 to move forward and backward from the right, if the dump truck is loaded with bulk materials , the conveyor belt 4 moves backwards by the length of a compartment 1, and cannot discharge all the materials. Therefore, this compartment 1 is more suitable for loading large-volume items that are not easy to collapse. As shown in Figure 6, the present The structure schematic diagram of the dump truck in the unloading state of the first kind of conveyor belt type dump truck constituted by the invention, the dump truck of this embodiment is easier to unload larger volume items.
如图7所示，给出了本发明的传输带式自卸货厢第2种实施例的结构示意图，其由车厢1、推板11、传输带4和后带轴3组成，后带轴3设置于车厢1的后端，后带轴3连接有驱使其转动的动力装置，动力装置由液压马达和减速机组成。推板11设置于车厢1中，推板11可设置于车厢1的横截面内，也可采用后倾的设置形式，车厢1内设置有对推板11的前后运动导向的导向机构。传输带4的位于车厢1的底部，传输带4的前端固定于推板11上，后端固定于后带轴3上，这样，在后带轴3转动过程中，即可带动传输带4和推板11同步向后运动，以便将车厢1内的物料卸下。As shown in Figure 7, the structural representation of the second embodiment of the conveyor belt type self-unloading cargo compartment of the present invention is provided, which is composed of a compartment 1, a push plate 11, a transmission belt 4 and a rear belt shaft 3, and the rear belt shaft 3 It is arranged at the rear end of the carriage 1, and the rear belt shaft 3 is connected with a power device driving it to rotate, and the power device is composed of a hydraulic motor and a reducer. Push pedal 11 is arranged in the compartment 1, and push pedal 11 can be arranged in the cross section of compartment 1, also can adopt the setting form of receding, and the guide mechanism to the forward and backward movement guidance of push pedal 11 is provided in compartment 1. The transmission belt 4 is positioned at the bottom of the compartment 1, the front end of the transmission belt 4 is fixed on the push plate 11, and the rear end is fixed on the rear belt shaft 3, so that the transmission belt 4 and the transmission belt 4 can be driven during the rotation of the rear belt shaft 3. The push plate 11 moves backward synchronously, so that the materials in the compartment 1 are unloaded.
当推板11跟随传输带4运动至车厢1的后端时，为了使推板11重新回到车厢1的前端，还需要设置驱使推板11由车厢1后端运动至前端的驱动装置，该驱动装置采用液压缸或电机，在采用电机的情况下，电机的输出轴连接有钢丝滚筒，钢丝滚筒上缠绕有与推板11固定连接的钢丝绳。When the push plate 11 moved to the rear end of the compartment 1 following the conveyor belt 4, in order to make the push plate 11 return to the front end of the compartment 1, it was also necessary to set a driving device that drives the push plate 11 to move from the rear end of the compartment 1 to the front end. The driving device adopts a hydraulic cylinder or a motor. In the case of using a motor, the output shaft of the motor is connected with a wire drum, and the wire drum is wound with a wire rope fixedly connected with the push plate 11.
如图8所示，给出了本发明的第2种传输带式自卸货厢构成的自卸车的结构示意图，其由车架7、悬架总承8、车轮9、推板11、传输带4和后带轴3组成，车架7起固定和支撑作用，悬架总承8固定于车架7后端的西方，车轮9固定于悬架总承8上。车厢1内所设置的推板11、传输带4和后带轴3与图7中所示的传输带式自卸货厢结构一致，由于后带轴3驱使传输带4和推板11同步从前向后运动，且推板11具有刮料的作用，这种结构可实现散装物料的一次性卸料。As shown in Figure 8, the structure schematic diagram of the dump truck that the 2nd kind of transmission belt type dump truck of the present invention is formed is provided, and it is made of vehicle frame 7, suspension assembly 8, wheel 9, push plate 11, transmission belt 4 and rear band axle 3 are formed, and vehicle frame 7 plays fixing and supporting effect, and suspension assembly 8 is fixed on the west of vehicle frame 7 rear ends, and wheel 9 is fixed on the suspension assembly 8.
