Description

Technical fields:

[0001] This utility model relates to the field of drug loading equipment technology, specifically a porous granular ammonium nitrate oil explosive loading vehicle. Background technology:

[0002] Porous granular ammonium nitrate explosive is an industrial explosive composed of porous granular ammonium nitrate and diesel fuel. When using it, a mixed porous granular ammonium nitrate explosive truck is needed to add the porous granular ammonium nitrate explosive to the borehole.

[0003] The problem is that the existing mixed-loading porous granular ammonium nitrate explosive trucks have a large overall structure, which makes it difficult for the vehicles to pass through narrow roads or slopes. This prevents the porous granular ammonium nitrate explosives from being transported to the designated location quickly. The explosives can only be bagged manually and then poured into the boreholes by hand to complete the loading process.

[0004] Porous granular ammonium nitrate explosives suffer from low transportation efficiency and slow loading when packaged in bags. Furthermore, the porous granular ammonium nitrate and diesel fuel are not mixed evenly inside the bag, affecting the quality and safety of engineering blasting. Utility model content:

[0005] The purpose of this invention is to provide a porous granular ammonium nitrate oil explosive loading vehicle to solve the problems mentioned in the background art.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-8 This utility model provides a technical solution for a porous granular ammonium nitrate explosive loading vehicle:

[0026] A porous granular ammonium nitrate explosive loading cart includes a walking cart, a loading box 3, a partition 4, a left screw conveyor 5, a right screw conveyor 6, a battery box 7, a left start switch 8, a right start switch 9, a left hopper 10, a right hopper 11, and a feed pipe 12.

[0027] The walking trolley includes a bracket 1 and a walking mechanism 2; the walking mechanism 2 is installed at the bottom of the bracket 1 and can be used as a walking trolley for independent use. The walking mechanism 2 includes two triangular brackets 2.1 respectively rotatably arranged at the bottom of the bracket 1, and each triangular bracket 2.1 is rotatably provided with three non-interfering walking wheels 2.2, which can be applicable to narrow road conditions or slopes, enabling the vehicle to pass quickly. Among them, the bracket 1 includes two handles 1.1, two outer connecting pipes 1.2 correspondingly connected to the handles 1.1, a T-shaped connecting pipe 1.3 connected between the two outer connecting pipes 1.2, and a protective pipe 1.4; rectangular slots 1.23 are opened on one side close to the handle 1.1 on the two outer connecting pipes 1.2 and the T-shaped connecting pipe 1.3, and a protective pipe 1.4 is fixed on the other side of the two outer connecting pipes 1.2 and the T-shaped connecting pipe 1.3 far from the handle 1.1, and the side-turning structure of the protective pipe 1.4 is in the shape of a "day" character.

[0028] Nine groups of limit sliders 3.1 are neatly arranged and fixed on the lower surface of the charging box 3. Each group of limit sliders 3.1 includes two limit plates 3.11. During installation, the two limit plates 3.11 of each group are respectively slidably clamped on the outer sides of the respective pipe walls in the bracket 1. At the same time, through holes 3.12 are opened on the limit plates 3.11. After installation, when the rectangular slots 1.23 are communicated with the through holes 3.12, it is convenient to quickly insert the pins 13, thereby preventing the tail of the charging box 3 from falling off; two limit strips 3.2 are fixed on the vertical surface at the front end of the charging box 3 close to the battery box 7. The two limit strips 3.2 are inserted into the protective pipe 1.4, and the upper surfaces of the two limit strips 3.2 are abutted against the lower surface of the top pipe wall of the protective pipe 1.4 to prevent the head of the charging box 3 from falling off. A rectangular through slot 1.31 is vertically opened in the middle of the T-shaped connecting pipe 1.3. A locking member 14 is rotatably arranged in the rectangular through slot 1.31. The locking member 14 includes a sector block 14.1 and a pull rod 14.2 and is integrally formed. The sector block 14.1 is movably placed above the rectangular through slot 1.31, and the bottom end of the pull rod 14.2 is located below the rectangular through slot 1.31. A cross bar 15 is fixed in the rectangular through slot 1.31 below the sector block 14.1. A tension spring 16 is connected between the bottom end of the pull rod 14.2 and the cross bar 15. The bottom end of the pull rod 14.2 is also connected to one end of a steel wire rope 17. The other end of the steel wire rope 17 penetrates into the T-shaped connecting pipe 1.3 and exits from the side close to the handle 1.1. A handle 18 is fixed at the other end of the steel wire rope 17. A clamping slot 3.3 corresponding to the sector block 14.1 is opened on the lower surface of the charging box 3. By clamping the sector block 14.1 with the clamping slot 3.3 on the charging box 3, it is possible to avoid the phenomenon of forward and backward sliding of the charging vehicle during travel, improve the stability and transportation efficiency of the vehicle, and finally achieve the rapid installation of the charging box 3 on the bracket 1.

[0029] To address the slow loading process and prevent uneven mixing of porous granular ammonium nitrate and diesel fuel, a partition 4 is vertically fixed along the length of the bottom of the loading box 3. A left spiral conveyor 5 and a right spiral conveyor 6 are rotatably mounted on either side of the partition 4 inside the loading box 3. A battery box 7 is installed on the loading box 3, supplying power to the left and right spiral conveyors 5 and 6. A left start switch 8 and a right start switch 9 are respectively installed on the two handles 1.1 of the support 1. These switches control the start and stop of the left and right spiral conveyors 5 and 6 via wiring. A left lower hopper 10 and a right lower hopper 11 are also located on either side of the partition 4 inside the loading box 3. Each of the left and right lower hoppers 10 and 11 is fixedly connected to a guide pipe 12. The guide pipe 12 has two layers: an inner layer made of PVC material and an outer layer of polyester filament. During the process, the left start switch 8 and the right start switch 9 can be pressed to control the start and stop of the left screw conveyor 5 and the right screw conveyor 6 respectively, thereby increasing the loading speed.

[0030] The actual operating principle is as follows: In the actual work site and quantity requirements, multiple walking carts can be set up. Then, according to the number of blast holes and the number of personnel, the number of charging boxes 3 can be installed appropriately. Three people form a group. One person supports the vehicle to move forward, and the other two people hold the guide pipe 12 respectively. After aligning it with the blast hole, they drive the screw conveyor to pour the porous granular ammonium nitrate explosive into the blast hole through the guide pipe 12 by pressing the start switch, thus completing the charging process.

[0031] When no longer needed for loading medicine, the pin 13 can be pulled out and the medicine box 3 can be removed. The trolley can still be used as a transportation tool without occupying resources, thus improving transportation capacity.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
