Embodiment 1

[0015] As shown in Figures 1 and 2, the present embodiment includes a frame on which a motor, a hydraulic pump, a hydraulic cylinder 7, a slurry cylinder 14 and a feed hopper 10 are installed, and the motor drives the hydraulic pump, the slurry cylinder and the feed hopper communicated and connected with the delivery pipeline 11. Wherein the motor adopts three motors 1, 2 and 3 with different powers, the powers of which are 22 kilowatts, 11 kilowatts and 5.5 kilowatts respectively. Three motors drive three hydraulic pumps 4, 5, 6 respectively, and their flows are respectively 125 ml / rev, 65 ml / rev and 32 ml / rev, and the three motors are respectively connected to pressure relay 14, which is controlled by the delivery pipeline. For the pressure control at the end, the inner diameter of the slurry conveying pipeline matched with the above-mentioned motor and hydraulic pump is preferably 80 mm.

[0016] When the slurry is output, the structure connected to the delivery pipeline i...

Embodiment 2

[0021] As shown in FIG. 5 , compared with Embodiment 1, this embodiment is a variable frequency motor 8 connected to a hydraulic pump 9 . Through frequency conversion motor, different output flows are provided.

[0022] The invention is mainly suitable for conveying slurry in building construction, and the supply amount of slurry can be 4-20 meters 3 / hour adjustment, head up to 30 meters. The work efficiency is high, the cost is low, and the application range is wide.

Abstract

The invention relates to a kind of slurry conveying appliance in building operation. It includes frame, electric machinery, hydraulic pump, hydro-cylinder, slurry jar and input hopper, among which the electric machinery drives the hydraulic pump; the slurry jar connects with the input hopper and link the supply line; the electric machinery and the hydraulic pump it driven has two groups at least. The invention can adjust the transport capacity of slurry and it is featured by high work efficiency and wide range of use.

Description

technical field [0001] The invention belongs to a conveying device for slurry in building construction, in particular to a plastering machine. Background technique [0002] In the field of construction, slurry transportation is an important link. At present, most of them still use tower cranes and derricks to transport slurry up and down. This transportation method covers a large area, complicated construction, labor-intensive workers, and many unsafe hazards. , personal injury accidents occur from time to time. [0003] The patent application No. 2003101056345 provides a slurry conveying device, which includes a double hydraulic cylinder and a piston in it, uses the movement of the piston to suck the slurry from the feed port, and uses the hydraulic control system to control the hydraulic cylinder and the slurry cylinder to achieve Continuous delivery of slurry. The disadvantage of this slurry conveying device is that the ash conveying volume is t...
