Description

Technical Field

[0001] This invention relates to the field of emulsion explosives production technology, specifically to a feeding structure and feeding method for a mixed emulsion explosives cart. Background Technology

[0002] Explosives are indispensable products in mining and soil excavation. With the development of the national economy, the use of explosives is constantly expanding. However, explosives are also hazardous materials, making the safety of their production, storage, transportation, and use a top priority. Emulsion explosives, as a new type of environmentally friendly explosive, have advantages such as strong water resistance, excellent detonation performance, and low production of toxic and harmful gases. They are being used more and more widely in the civil explosives industry and will gradually replace traditional ammonium nitrate explosives.

[0003] The existing on-site emulsion explosive loading trolleys load emulsion explosives into the blast holes via a delivery pipe. To accommodate blast holes at different locations, the loading trolleys are equipped with long delivery pipes. During operation, the delivery pipe inside the basket is affected by the downward gravity. The weight of the emulsion explosives filling the delivery pipe and the pipe itself affects the delivery device, causing inaccurate delivery and resulting in poor blasting effect.

[0004] In the four main stages of drilling, blasting, shoveling, and transportation in large and medium-sized underground mines in China, the blasting stage requires on-site mixing of emulsion explosives. Currently, the underground charging equipment used is mostly an on-site emulsion explosive mixing charging trolley, which mainly consists of a chassis, driver's cab, underground on-site emulsion explosive mixing preparation device, lifting arm, and basket installed on the lifting arm. When charging, the driver drives the trolley to the vicinity of the blast hole, which requires precise control. If the trolley gets too close to the blast hole, it will also cause inconvenience in charging. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution: a delivery structure for a mixed emulsion explosive vehicle, comprising a vehicle body, a box fixedly installed on the vehicle body, a delivery device movably installed inside the box, the delivery device comprising a rotating shaft and a rotating body, the top end of the rotating shaft being movably connected to the top end of the box, a sliding groove three being provided at the bottom of the box, the bottom of the rotating body being engaged in the sliding groove three, connecting rods being evenly distributed on the circumference of the delivery device, a placement groove being fixedly installed on each connecting rod, a collection groove being fixedly installed inside the box, and a handle being fixedly installed on the rotating shaft.

[0007] Preferably, a motor is fixedly installed at the top of the housing, and an action rod is fixedly installed at the output end of the motor. A sliding groove is opened at the top of the housing, and a rotating shaft is movably engaged in the sliding groove and extends out of the housing. A track is connected between the top of the rotating shaft and the motor.

[0008] Preferably, the top of the box body is also provided with a second sliding groove, and an action rod is movably engaged in the second sliding groove, and the action rod also interacts with the track.

[0009] Preferably, the connecting rod is movably connected to the rotating shaft, and the rotating body is provided with four evenly distributed sliding grooves. The connecting rod is movably engaged in the four sliding grooves, and springs are fixedly installed at both the upper and lower ends of the connecting rod inside the four sliding grooves.

[0010] Preferably, the connecting rod is divided into two sections that are rotatably connected. A gear is fixedly installed on the section of the connecting rod near the placement groove, and the two ends of the connecting rod are connected to each other by a helical spring.

[0011] Preferably, a rod is fixedly installed at the bottom end of the rotating shaft, an action plate is fixedly installed on the rod, the top end of the action plate is provided with teeth, and the height of the action plate is adapted to the position of the connecting rod and the gear.

[0012] Preferably, the placement tank is designed to be hemispherical, and the horizontal distance from the placement tank to the rotating shaft is adapted to the horizontal distance from the collection tank to the rotating shaft.

[0013] Preferably, the first actuating rod has five sliding grooves on both sides, and a locking block is fixedly installed on the first actuating rod relative to the sliding groove five. The locking block engages in the sliding groove five. A pulley is rotatably connected to the middle position of the first actuating rod, and a track engages in the pulley. Fixing holes are provided on the box body on both sides of the second sliding groove, and a fixing mechanism is movably installed between the fixing holes and the first actuating rod.

[0014] Preferably, the fixing mechanism includes a rod body, the rod body is L-shaped, the two ends of the rod body have the same structure, and each end is provided with a sliding groove six. A spring two is fixedly installed in each sliding groove six. A connecting rod is fixedly installed on the spring two. A locking rod is fixedly installed on the connecting rod. A pulling block is fixedly installed on each locking rod. The fixing hole is adapted to the size of the locking rod.

[0015] A method for delivering mixed emulsion explosives by vehicle, characterized by the following steps:

[0016] A. Pull the handle to move the medicine delivery device to the outside of the box;

[0017] B. Turn on the motor, so that the second actuating rod drives the rotating shaft to rotate, and the rotating shaft drives the rotating body to rotate, so that the placement tank rotates on the rotating body;

[0018] C. After the emulsion explosive is placed in the tank, the gear on the connecting rod meshes with the action plate, causing the two sections of the connecting rod to rotate relative to each other, thereby causing the tank to flip over and the emulsion explosive to fall into the collection tank.

[0019] D. After the emulsion explosive is poured out, the placement tank no longer receives pressure from the emulsion explosive, causing the connecting rod and the placement tank to move upward. At this time, the gear and the action plate separate from each other, and the helical springs at both ends of the connecting rod are used to make the placement tank return to its original position.

[0020] Compared with the prior art, the present invention provides a charging structure and charging method for a mixed emulsion explosive vehicle, which has the following beneficial effects:

[0021] 1. The feeding structure and feeding method of this mixed emulsion explosive cart: By moving the handle, the feeding device is moved to the outside of the box, making it easier to place the emulsion explosive into the placement tank. Then, the motor is turned on, which causes the second actuating rod to drive the rotating shaft to rotate. The rotating shaft drives the rotating body to rotate, which in turn causes the placement tank to rotate on the rotating body. When the placement tank is filled with emulsion explosive, the placement tank drives the connecting rod to move downward in the slide chute. When the placement tank and the connecting rod rotate around the rotating body, the gear on the connecting rod meshes with the actuating plate, causing the two sections of the connecting rod to rotate relative to each other. This causes the placement tank to flip, allowing the emulsion explosive to fall into the collection tank, thus achieving the effect of collecting the emulsion explosive.

[0022] 2. The feeding structure and feeding method of the mixed emulsion explosive cart: After the emulsion explosive is poured out, the placement tank no longer receives pressure from the emulsion explosive, causing the connecting rod and the placement tank to move upward. At this time, the gear and the action plate separate from each other. By utilizing the helical springs on both ends of the connecting rod, the placement tank is brought back to its original position, making it convenient for the subsequent placement of emulsion explosive.

[0023] 3. The feeding structure and feeding method of the mixed emulsion explosive vehicle, when adjusting the position of the rotating shaft and the rotating body, the adjusting rod one is positioned on the upper part of the slide groove two, so that the track acts on the rotating shaft, the adjusting rod two and the adjusting rod one, to ensure the tension of the track, thereby ensuring the rotation effect of the motor belt on the adjusting rod two and the rotating shaft, and ensuring the normal operation of the device.

[0024] 4. The feeding structure and feeding method of the mixed emulsion explosive vehicle utilize the elastic effect of spring one. When the emulsion explosive is placed in the tank, the gear and the action plate can mesh with each other. When there is no emulsion explosive, the gear and the action plate separate from each other, achieving the effect of automatically controlling the pouring of emulsion explosive. At the same time, it prevents the two ends of the connecting rod from rotating in one direction all the time, which would cause damage to the helical spring one. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0035] Please see Figure 1-6A delivery structure for a mixed emulsion explosive vehicle includes a vehicle body 10, a box 20 fixedly mounted on the vehicle body 10, and a delivery device 30 movably mounted inside the box 20. The delivery device 30 includes a rotating shaft 31 and a rotating body 32. The top end of the rotating shaft 31 is movably connected to the top end of the box 20. A sliding groove 37 is formed at the bottom of the box 20, and the bottom of the rotating body 32 is engaged within the sliding groove 37. Connecting rods 35 are evenly distributed on the circumference of the delivery device 30, and a placement groove 34 is fixedly mounted on each connecting rod 35. A collection groove 28 is fixedly mounted inside the box 20, and a handle 33 is fixedly mounted on the rotating shaft 31.

[0036] A motor 25 is fixedly installed at the top of the housing 20. An actuating rod 26 is fixedly installed on the output end of the motor 25. A sliding groove 21 is opened at the top of the housing 20. A rotating shaft 31 is movably engaged in the sliding groove 21 and extends out of the housing 20. A track 24 is connected between the top of the rotating shaft 31 and the motor 25.

[0037] The top of the box 20 is also provided with a second sliding groove 22, and an action rod 23 is movably engaged in the second sliding groove 22. The action rod 23 also interacts with the track 24.

[0038] The connecting rod 35 is movably connected to the rotating shaft 31. The rotating body 32 is provided with evenly distributed sliding grooves 36. The connecting rod 35 is movably engaged in the sliding grooves 36. Springs 38 are fixedly installed at both the upper and lower ends of the connecting rod 35 inside the sliding grooves 36.

[0039] The connecting rod 35 is divided into two sections that are rotatably connected. A gear 39 is fixedly installed on the section of the connecting rod 35 near the placement groove 34. The two ends of the connecting rod 35 are connected to each other by a helical spring.

[0040] A rod 41 is fixedly installed at the bottom end of the rotating shaft 31. An action plate 29 is fixedly installed on the rod 41. The top end of the action plate 29 is provided with teeth, and the height of the action plate 29 is adapted to the position of the connecting rod 35 and the gear 39.

[0041] The placement tank 34 is designed to be hemispherical, and the horizontal distance from the placement tank 34 to the rotating shaft 31 is adapted to the horizontal distance from the collection tank 28 to the rotating shaft 31.

[0042] In use, pull handle 33 to move the delivery device 30 to the outside of the housing 20, facilitating the placement of the emulsion explosive into the placement trough 34. Then, turn on motor 25, causing the actuating rod 26 to drive the rotating shaft 31 to rotate. The rotating shaft 31 drives the rotating body 32 to rotate, causing the placement trough 34 to rotate on the rotating body 32. When the placement trough 34 is filled with emulsion explosive, the placement trough 34 drives the connecting rod 35 to move downwards in the sliding groove 36. As the placement trough 34 and the connecting rod 35 rotate around the rotating body 32, the connecting rod 35... The gear 39 meshes with the action plate 29, causing the two sections of the connecting rod 35 to rotate relative to each other. This causes the placement tank 34 to flip, allowing the emulsion explosive to fall into the collection tank 28, thus achieving the effect of collecting the emulsion explosive. After the emulsion explosive is poured out, the placement tank 34 is no longer under the pressure of the emulsion explosive, causing the connecting rod 35 and the placement tank 34 to move upward. At this time, the gear 39 separates from the action plate 29. Using the action of the helical springs on both sections of the connecting rod 35, the placement tank 34 returns to its original position, making it convenient for subsequent placement of emulsion explosive.

[0043] When adjusting the positions of the rotating shaft 31 and the rotating body 32, the adjusting rod 23 is positioned above the sliding groove 22, so that the track 24 acts on the rotating shaft 31, the adjusting rod 26, and the adjusting rod 23, ensuring the tension of the track 24, thereby ensuring the rotation effect of the motor 25 on the adjusting rod 26 and the rotating shaft 31, and ensuring the normal operation of the device.

[0044] Utilizing the elasticity of spring 38, gear 39 and actuating plate 29 can mesh with each other when the emulsion explosive is contained in the placement tank 34. When there is no emulsion explosive, gear 39 and actuating plate 29 separate from each other, achieving the effect of automatically controlling the pouring of emulsion explosive. At the same time, it prevents the two ends of the connecting rod 35 from rotating in one direction all the time, which would cause damage to the helical spring. Example

[0045] Please see Figure 7-8 The two sides of the 23 are provided with sliding grooves 212. The 23 is fixedly installed with a locking block 231 relative to the sliding groove 212. The locking block 231 is engaged in the sliding groove 212. The middle position of the 23 is rotatably connected with a pulley 232. The pulley 232 is engaged with a 24. The 20 is provided with fixing holes 210 on both sides of the 22. A fixing mechanism 40 is movably installed between the fixing holes 210 and the 23.

[0046] The fixing mechanism 40 includes a rod 47, which is L-shaped. Both ends of the rod 47 have the same structure and are provided with a sliding groove 43 at both ends. A spring 42 is fixedly installed in each sliding groove 43. A connecting rod 44 is fixedly installed on the spring 42. A locking rod 46 is fixedly installed on the connecting rod 44. A pulling block 45 is fixedly installed on each locking rod 46. The fixing hole 210 is adapted to the size of the locking rod 46.

[0047] The engagement of the locking block 231 and the slide rail 212 ensures the stability of 23 when it moves within 22, and also ensures the stability of 23 when 24 rotates on the pulley 232. After 23 is moved to the correct position, the extension and retraction of the spring 42 pulls the pulling block 45, causing the connecting rod 44 to enter the slide rail 43. Then, the locking rods 46 at both ends of the rod 47 are respectively engaged with 23 and the fixing hole 210. The extension and retraction of the fixing mechanism 40 ensures that the fixing mechanism 40 can be engaged with the fixing hole 210 at any position, thereby achieving the effect of fixing 23 at any position. While ensuring the fixing effect of 23, it can be fixed arbitrarily. At the same time, pulling the pulling block 45 can move the locking rods 46 out of the fixing hole 210, thereby achieving the effect of convenient movement of 23.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
