Description

Technical Field

[0001] The utility model belongs to the technical field of emulsion explosives, and in particular relates to an emulsion explosive mixing vehicle which is convenient for loading. Background Art

[0002] Emulsion explosives use emulsifiers to evenly disperse droplets of oxidant salt aqueous solution in an oil phase continuous medium containing porous materials such as dispersed bubbles or hollow glass microspheres to form an oil-in-water type emulsion explosive. In recent years, on-site mixing vehicles are usually used to mix and load explosives, which has the advantages of mixing and using immediately, short construction period, reducing the danger of long-distance transportation and rolling loading and unloading of explosives, and saving blasting costs.

[0003] When mixing emulsion explosives, it is necessary to pour the raw materials into the mixing vehicle, but since the height of the mixing vehicle is generally high, it is not convenient for users to directly pour the raw materials into the mixing vehicle. CN 219368559 U discloses an emulsion explosive mixing vehicle with a protective effect, which includes a chassis, a fixed barrel is fixedly installed on the left side of the top of the chassis, a transport pipe is fixedly installed on the right side of the fixed barrel, a feeding port is fixedly installed on the top of the transport pipe, a mounting box is fixedly installed on the top of the feeding port, a fixed box is fixedly installed on the top of the mounting box, and electric slide rails are fixedly installed on both sides of the front and rear of the surface of the fixed box. When in use, the raw materials can be poured into the movable box first, and then the electric slide rails are started to drive the mounting plate to move upward. When the movable box moves to one side of the top of the fixed box, the electric push rod can be started to tilt the movable box upward, so that the raw materials inside the movable box are poured into the inside of the fixed box, so that the raw materials can be mixed and stirred later. The mixing vehicle is intended to facilitate the transportation of raw materials into the interior of the fixed box with a higher height, so as to facilitate the pouring of raw materials. However, the following problems still exist during use: 1. The electric push rod pushes the movable box to flip at a small angle, which is not conducive to emptying the raw materials in the movable box; 2. The movable plate of the fixed box needs to be covered manually after the movable box is loaded with materials, which is not conducive to timely and rapid mixing operations and also increases the workload of the staff. Utility Model Content

[0004] The utility model aims to provide an emulsion explosive mixing vehicle which has a reasonable structure, is reliable in use and is easy to load, solves the problem that the raw materials in the movable box are not easy to empty when the mixing vehicle is mixing and loading materials, ensures the loading amount and loading accuracy each time, and at the same time, reduces the labor intensity of the staff and ensures production safety.

[0005] The technical solution of the utility model is:

[0006] The invention discloses an emulsion explosive mixing vehicle which is convenient for loading, comprising a chassis, a fixed barrel arranged on the chassis, a horizontal screw propeller connected to the fixed barrel, a mixing chamber connected to the top of the inlet of the horizontal screw propeller, and a protective cover arranged on the top of the mixing chamber. The technical key points are as follows: support rods are respectively arranged on the same side of the mixing chamber and the protective cover, a connecting rod is hinged between the ends of the two support rods, a left and a right Z-direction linear module are fixed to the tail of the chassis, the two Z-direction linear modules are connected and fixed to an annular bracket fixed to the periphery of the mixing chamber, two supporting ears are symmetrically arranged on the annular bracket, and a push-pull cylinder is hinged with the supporting ears, the telescopic rod ends of the push-pull cylinder are hinged to the side wall of the protective cover, the two push-pull cylinders are symmetrically arranged on both sides of the vertical plane where the connecting rod is located, the sliders of the two Z-direction linear modules are arranged relatively and are respectively connected to slide seats of equal height, horizontal short shafts are respectively arranged between the two slide seats, the opposite ends of the two horizontal short shafts are connected to a feeding barrel, and a servo motor connected to the horizontal short shaft is fixed to the outside of one of the slide seats.

[0007] In the above-mentioned emulsion explosive mixing vehicle which is convenient for loading, a proximity switch facing the position between the two Z-direction linear modules is fixed on the protective cover.

[0008] In the above-mentioned emulsion explosive mixing vehicle which is convenient for loading, a pressure sensor is fixed on the upper edge of the mixing bin near the position between the Z-direction linear modules.

[0009] The beneficial effects of the utility model are:

[0010] 1. Two Z-axis linear modules are used to drive the slide to rise, thereby driving the loading barrel to rise, and the servo motor drives the horizontal short shaft and the loading barrel to flip, and the materials in them are dumped into the mixing bin. Compared with the existing technology, the servo motor drives the loading barrel to flip at a large angle and has good applicability, which can achieve the purpose of completely emptying the raw materials in the movable box (loading barrel), thereby ensuring the loading amount and loading accuracy each time.

[0011] 2. When the loading barrel rises to the side of the protective cover, the push-pull cylinder pushes the protective cover to open, so that the raw materials in the loading barrel can be poured in. After pouring, the push-pull cylinder is used to pull the protective cover to close. The staff does not need to open and close the protective cover, thereby reducing the labor intensity of the staff and ensuring production safety. BRIEF DESCRIPTION OF THE DRAWINGS
