Technical Field
[0001] The utility model relates to a locking device for the rear wall panel of a crawler impact crusher station, belonging to the technical field of improvement of a receiving hopper. Background Art
[0002] A mobile crusher station is a movable device for crushing large materials into small materials. A feeder is a device for feeding the mobile crusher station. An excavator or a loader dumps materials onto a receiving hopper, and the receiving hopper conveys the materials to a crushing main machine through the feeder. The rear wall panel is an important part of the receiving hopper, located behind the receiving hopper to prevent materials from leaking out from the rear.
[0003] As a component for receiving material dumping of the mobile crusher station, the receiving hopper consists of a left wall panel 1, a right wall panel 2, a rear wall panel 3, support oil cylinders and corresponding support components. The three wall panels are installed on a main frame and can rotate around corresponding installation shafts by relying on the oil cylinders, rising in the working state and descending in the transportation state. Its structure is as Figure 3 shown.
[0004] The current technology has incomplete considerations and has the following drawbacks: the split design of the left and right wall panels and the rear wall panel lacks stable connection, resulting in poor overall stability.
[0005] To solve one of the above problems, there is an urgent need for a locking device for the rear wall panel of a crawler impact crusher station. Content of the Utility Model
[0006] According to the deficiencies in the above prior art, the technical problem to be solved by the utility model is: how to connect the left and right wall panels and the rear wall panel of the receiving hopper into one body with wedge blocks by adding a first locking mechanism and a second locking mechanism, so as to increase the overall safety. For this purpose, a locking device for the rear wall panel of a crawler impact crusher station is provided.
[0007] The locking device for the rear wall panel of the crawler impact crusher station described in the utility model is characterized in that: it includes a first locking mechanism and a second locking mechanism installed on the rear wall panel. The first locking mechanism and the second locking mechanism are used to lock or unlock the rear wall panel. The first locking mechanism includes an ear plate A welded on the right wall panel and a push-pull oil cylinder A installed on the rear wall panel. The telescopic end of the push-pull oil cylinder A is installed with a wedge block A through a pin A. A lock hole A matching with the wedge block A is opened on the ear plate A. The push-pull oil cylinder A drives the wedge block A to be locked or unlocked with the ear plate A.
[0008] By adding a first locking mechanism and a second locking mechanism, the left and right wall panels and the rear wall panel of the receiving hopper are connected into one body with wedge blocks, increasing the overall safety; secondly, the insertion and extraction of the wedge blocks can be controlled by using hydraulic cylinders, increasing the operation convenience.
[0009] Preferably, the push-pull oil cylinder A is installed on the rear wall panel through the oil cylinder fixing seat A. A guide plate A for guiding the wedge block A is also installed on the rear wall panel, and the guide plate A is provided with a guide hole A through which the wedge block A passes.
[0010] Preferably, a protective frame A covering the periphery of the wedge block A is installed on the rear wall panel.
[0011] Preferably, the second locking mechanism includes an ear plate B welded on the left wall panel and a push-pull oil cylinder B installed on the rear wall panel. The telescopic end of the push-pull oil cylinder B is installed with a wedge block B through a pin B. A lock hole B matching the wedge block B is opened on the ear plate B, and the push-pull oil cylinder B drives the wedge block B to be locked or unlocked with the ear plate B.
[0012] Preferably, the push-pull oil cylinder B is installed on the rear wall panel through the oil cylinder fixing seat B. A guide plate B for guiding the wedge block B is also installed on the rear wall panel, and the guide plate B is provided with a guide hole B through which the wedge block B passes. A protective frame A covering the periphery of the wedge block B is installed on the rear wall panel.
[0013] Preferably, the first locking mechanism and the second locking mechanism are symmetrically distributed.
[0014] Preferably, a hydraulic joint with a throttle hole is respectively arranged at the tail parts of the push-pull oil cylinder A and the push-pull oil cylinder B. Adding a throttle hole to the rodless cavity of the oil cylinder can slow down the action speed of the oil cylinder, and can also make the two groups of oil cylinders act simultaneously, increasing the operation convenience.
[0015] Working principle:
[0016] To prevent the support members of each wall panel of the receiving hopper from failing, a first locking mechanism and a second locking mechanism are added to the rear wall panel. The wedge block of the locking mechanism is connected to the oil cylinder through a pin, and the oil cylinder is installed on the rear wall panel through a fixing seat and bolts. The wedge block is inserted into the ear plate of the side wall panel by the telescopic movement of the oil cylinder. However, due to gravity, the head of the wedge block will shift. To enable the wedge block to accurately insert into the ear plate, a guide plate is added, and the protective frame and the guide plate are fixed to the rear wall panel with bolts. To enable the two side oil cylinders to extend and retract simultaneously, a hydraulic joint with a throttle hole is installed in the rodless cavity of the oil cylinder.
