Traveling type automatic material loading patching machine device

Abstract

The invention relates to a traveling type automatic material loading patching machine device. The device comprises a device body rack, a charging hopper, a patching machine and a hydraulic pressure oil cylinder used for loading material. The device is characterized in that the charging hopper is in a hinged connection with a hinged joint point which is close to device body rear portion, the upper portion of the charging hopper is in a hinged connection with a hinged joint point which is close to the head portion of the device body sequentially through a pair of pull rods and a pair of connecting rods which are in the hinged connection, the hydraulic pressure oil cylinder is installed at the front of the charging hopper, a cylinder body of the hydraulic pressure oil cylinder is in a hinged connection with a hinged joint point which is close to the middle of the device body, a push rod of the hydraulic pressure oil cylinder is in a hinged connection with a hinged joint point of the pull rods and the connecting rods, and therefore a five-connecting rod charging mechanism composed of the device body rack, connecting rods, the hydraulic pressure oil cylinder, the push rod and the charging hopper is formed to load materials. According to the traveling type automatic material loading patching machine device, the complete device is beneficial to widening the charging hopper and substantially increasing the hopper capacity, and the hopper capacity can be increased by about 100%, lifting and turning performances are stable, the charging operation is convenient, the structure is simple, the device is energy-saving and environment-friendly, and the cost is low.

Description

(1) Technical field [0001] The invention relates to the design technology of a spraying machine in construction engineering, in particular to a walking type automatic feeding spraying machine device for spraying concrete. (2) Background technology [0002] Currently used in the construction site construction process, the spraying machine for concrete spraying and pouring generally adopts two methods of manual feeding or using a hydraulic cylinder to lift the hopper to load (refer to charging the spraying machine). Among them, manual feeding is intensive, and the concrete material is seriously leaked, and the entire construction period is affected because of the slow feeding speed. In order to improve the spraying work efficiency, the Chinese patent No. 201020252779.3 discloses a spraying machine that utilizes a hydraulic cylinder to lift the hopper to load materials. A loading hopper is hinged, and one end of the charging hopper is hinged to the side of the feed port of the...

Problems solved by technology

[0003] 1. Since the two hydraulic cylinders are arranged outside the loading hopper to be lifted, the cylinder body and the push rod of the two hydraulic cylinders are respectively hinged with the vehicle body and the loading hopper, so the loading hopper will be affected by the width of the vehicle body and the outer hydraulic cylinder. Due to the limitation, the width of the hopper cannot exceed the width of the car body, resulting in a small capacity of the loading hopper, which is not convenient for unloading construction of large dump trucks; when the capacity of the loading hopper is designed to be larger, the width of the car body also needs to be designed larger. It will also make the structure of the car body more complex and bulky

[0004] 2. The charging hopper of the spraying machine is hinged on the vehicle body beside the feed port of the spraying machine. The cylinder body and the push rod of the hydraulic cylinder are respectively hinged with the vehicle body and the loading hopper (forming a three-link structure). The expansion and contraction of the push rod of the oil cylinder makes one end of the loading hopper lift and tilt to realize loading. Since the two hydraulic cylinders are installed on both sides of the loading hopper, the width of the loading hopper is limited (note: the width of the loading hopper can only reach 2.3- -2.6m or so), in order to achieve the specified hopper capacity, the length of the hopper needs to be desi
