Description

Technical Field

[0001] This utility model relates to the technical field of explosive mixing, and more specifically, it relates to a conveyor screw for on-site explosive mixing. Background Technology

[0002] Explosive mixing trucks are used in blasting operations to mix the various components of explosives and load them into the blast holes. In particular, granular ammonium nitrate (ANN) explosives are mixed thoroughly and then loaded into the blast holes. After a period of time in the blast holes, they are called ANN explosives.

[0003] When transporting mixed explosives, existing mixed-load trucks mostly use a rotating conveying screw connected to one side of the truck to transport the explosives into the blast hole. However, for existing conveying screws, the distance between the inlet and outlet is fixed. This means that the conveying screw can only transport materials on an arc with the inlet as the center and the distance between the inlet and outlet as the radius, which increases the difficulty of locating the blast hole when the mixed-load truck is operating on site. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a conveying screw for on-site mixing of explosives. By setting a main screw and a secondary screw, the degree of freedom of the conveying screw is increased, which can significantly expand the working range and positioning accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a conveying screw for on-site mixing of explosives, comprising a main screw, wherein one end of the feed inlet of the main screw is rotatably connected to the mixing vehicle; A secondary spiral, wherein the feed end of the secondary spiral is rotatably connected to the discharge end of the main spiral and the feed end of the secondary spiral is connected to the discharge end of the main spiral; And a rotary device for driving the rotation of the secondary helix on the primary helix.

[0006] The present invention is further configured such that: a vertically arranged discharge pipe is fixedly connected to the bottom of one end of the main spiral discharge; The top of one end of the secondary spiral feed is fixedly connected to a vertically arranged feed pipe, which is coaxial with the discharge pipe and rotatably connected to the bottom of the discharge pipe.

[0007] The present invention is further configured to include an auxiliary drive device, which is used to drive the main auger to rotate on the mixing vehicle.

[0008] The present invention is further configured to include a rotating component, which is fixedly connected to the bottom of one end of the main screw feeder and rotatably connected to the mixing vehicle. The auxiliary drive device is used to drive the rotating parts to rotate on the mixing vehicle.

[0009] The present invention is further configured such that a receiving pipe for receiving the mixed explosives is fixedly connected to the top of one end of the main spiral feed.

[0010] The present invention is further configured such that the rotary device and the auxiliary drive device are configured as rotary drives or hydraulic cylinders.

[0011] The present invention is further configured such that mechanical limiters and / or encoders are provided at the rotary device and the auxiliary drive device.

[0012] In summary, the present invention has the following advantages over the prior art: by setting the main spiral and the secondary spiral, the present invention increases the degree of freedom of the conveying spiral, which can significantly expand the working range and positioning accuracy.
