DETAILED DESCRIPTION Example 1

[0033] like Figures 1-6 As shown, a diversion-type horizontal drill for ore mining includes a drill rod 1, which includes a rotating rod body 11, a drill bit 12 and a fixed pipe 13. The drill bit 12 is threadedly connected to the rotating rod body 11, and the fixed pipe 13 is connected to the drill bit 12 through the rotating rod body 11. The present invention is installed on a drilling rig when in use. In order to solve the problem of drill bit overheating caused by the crushing of ore over time in the prior art, a flow channel for water flow is provided between the fixed pipe 13, the rotating rod body 11 and the drill bit 12, and the flow channel is connected to a water source through an external connecting pipe. The connected water source can be used to cool the drill bit 12 to avoid the problem of excessive heat generation in the drill bit 12, which affects its service life.

[0034] Furthermore, the drill bit 12 is provided with a crushing portion at the end thereof, and a plurality of guide grooves 121 are provided on the surface of the crushing portion, and the guide grooves 121 extend in a spiral from the crushing portion to the other end of the drill bit 12; the drill bit 12 is provided with a diversion hole 122 and a cooling flow channel 123, and the cooling flow channel 123 extends in the direction of each guide groove 121, and each cooling flow channel 123 is connected to the flow channel through the diversion hole 122, and the cooling flow channel 123 is connected to the outside through a plurality of openings 1231; this arrangement is to allow the water used for cooling to flow along the diversion hole 122. Flowing with the cooling flow channel 123 allows water to spread more fully into the drill bit 12 to cool the drill bit 12. The purpose of providing the guide groove 121 in the present invention is to utilize the guide groove 121 to discharge the crushed gravel outward along the guide groove 121 when the drill bit 12 rotates. As shown in the drill rod 1, the outer diameter of the drill bit 12 is larger than the rotating rod body 11, and the outer diameter of the middle part of the drill bit 12 is gradually reduced, which can effectively form a gap between the ore for discharging gravel, thereby utilizing the guidance of the guide groove 121 to discharge the gravel.

[0035] Furthermore, a through hole is defined in the fixing tube 13 , and a first through hole 1122 is defined in the rotating rod 11 . The through hole and the first through hole 1122 constitute the aforementioned flow channel.

[0036] In order to solve the installation problem of the drill bit 12 and improve the firmness of the installation, the rotating rod body 11 is provided with a deformation pipe body 111 and a threaded fixing pipe 112, and the drill bit 12 is provided with a corresponding tubular groove 124 and a threaded groove 125. When the drill bit 12 is installed on the rotating rod body 11, the threaded fixing pipe 112 is in threaded connection with the threaded groove 125, and the deformation pipe body 111 is inserted into the tubular groove 124. During the rotating installation of the drill bit 12, the deformation pipe body 111 is continuously embedded into the tubular groove 124, thereby forming a sufficient abutting effect, and correspondingly improving the difficulty of installation and disassembly of the drill bit 12. The self-locking function is formed by the threads on the outer side of the threaded fixing pipe 112, so as to avoid the loosening of the drill bit during work. The rotating direction of the drill bit 12 during rotation is opposite to the extension direction of the threads on the outer side of the threaded fixing pipe 112. The end of the rotating rod body 11 away from the threaded fixing pipe 112 is provided with a clamping groove 114, and the fixing pipe 13 is rotatably installed in the clamping groove 114 through a clamping step 131.

[0037] In addition, the thickness of the deformation pipe body 111 is greater than the width of the tubular groove 124, and the deformation pipe body 111 is made of rubber material. When the deformation pipe body 111 is inserted into the tubular groove 124, the deformation pipe body 111 and the tubular groove 124 form an interference fit. The significance of the interference fit is to improve the tightness of the installation by using the deformation pipe body 111. In order to more conveniently embed the deformation pipe body 111 into the tubular groove 124, the thickness of the end of the deformation pipe body 111 gradually decreases.

[0038] At the same time, since water flows along the fixing pipe 13 to the drill bit 12, and the connecting end of the drill bit 12 and the rotating rod body 11 is separated, in order to avoid the stability of water pressure and avoid the overflow of water, the root of the threaded fixing pipe 112 is further sleeved with a sealing sheet body 113. The outer diameter of the sealing sheet body 113 is greater than the inner diameter of the threaded groove 125, and the thickness of the sealing sheet body 113 gradually decreases from the edge to the middle. In this way, during the rotation of the drill bit 12, the drill bit 12 gradually approaches and extrudes the sealing sheet body 113, so that the sealing sheet body 113 gradually deforms after being extruded, thereby filling the gap between the threaded fixing pipe 112 and the threaded groove 125, and avoiding the seepage of water flow.

[0039] In addition, the side of the threaded fixing pipe 112 away from the sealing sheet body 113 is further provided with a protruding portion 1121, and the threaded groove 125 is provided with a corresponding groove. The protruding portion 1121 abuts against the groove.

[0040] Furthermore, in order to increase the area of ​​water sprayed along the openings 1231, a pressure-boosting member 1233 is provided in each of the openings 1231 of the present invention. A gap for water to flow through is provided between the pressure-boosting member 1233 and the opening 1231. The rotating member 332 has an inverted cone-shaped structure. The gap is for water to be discharged. The inverted cone-shaped structure of the rotating member 332 is used to increase the pressure of the liquid during the spraying, thereby further removing gravel attached to the surface of the guide groove 121 or wetting the soil so that the gravel can be discharged outwards during the subsequent pushing of the gravel.

[0041] In addition, each booster 1233 includes a limiting plate 331 and a rotating member 332. The rotating member 332 is sleeved on the outside of the limiting plate 331. The limiting plate 331 is connected to the rotating member 332 through a plurality of connecting members 3311. The surface of the opening 1231 has an inwardly recessed movable groove 1232, and the limiting plate 331 is movably installed in the movable groove 1232.

[0042] At the same time, a plurality of guide grooves 3322 extending in an arc shape are provided on the outer side of the rotating member 332. The guide grooves 3322 are arranged in a ring array. When in use, the upper side of the rotating member 332 can be used to block the incoming gravel and mud. When the water flow hits the guide grooves 3322 on the surface of the rotating member 332, it will drive the rotating member 332 to rotate, and the gravel and mud on the surface of the rotating member 332 will be thrown out and washed away by the rushing water.

[0043] Furthermore, the upper end of the rotating member 332 is provided with a groove 3321 whose depth gradually deepens from the edge to the middle, and the lower end surface of the rotating member 332 is connected to the surface of the groove 3321 through a second through hole 3323, and the inner diameter of the second through hole 3323 gradually decreases from the bottom to the top. This setting is to allow water to wash away the gravel and soil on the surface of the groove 3321, and increase the water output so that the ore being crushed can be fully moistened. Example 2

[0044] like Figure 7 As shown, a drilling rig is proposed in this embodiment, which includes the diversion-type horizontal drill described in Example 1, and the drilling rig also includes a movable base 2, a motor 3, and a fixed base 4. The fixed base 4 is symmetrically arranged on the left and right sides of the movable base 2, and the two fixed bases 4 are connected by multiple guide rails, each of which passes through the movable base 2. The motor 3 is installed on the movable base 2, and the drill rod 1 is respectively arranged on the front and rear sides of the movable base 2. The motor 3 is provided with an output shaft 31, and the output shaft 31 forms a belt drive with the drill rod 1 through two transmission belts 32, so as to drive the drill rod 1 to crush the ore through the rotation of the output shaft 31.

[0045] The above merely describes preferred embodiments of the present application, and therefore cannot limit the scope of the present application, i.e. equivalent changes and modifications made according to the patent scope and content of the present application should still fall within the scope of the present application.
