Description

Technical Field

[0001] The utility model relates to the technical field of geological exploration equipment, in particular to a stone crushing device for geological exploration. Background Art

[0002] The field of geological engineering is based on the theories of natural science and earth science, with geological surveys, mineral resource surveys and explorations, and engineering problems involving the geological structure and geological background of major projects as its main objects. During geological surveys, it is often necessary to crush large pieces of ore to help researchers study the ore.

[0003] Chinese patent document CN219923218U discloses a rock crushing device for geological exploration, including an installation box, a primary crushing part is installed inside the installation box, a mounting cylinder connected to the installation box is installed at the bottom of the installation box, and a secondary crushing part is installed inside the installation cylinder; a feed port is provided on the top surface of the installation box, and protective doors are hingedly installed on both sides of the inner wall of the feed port, and a discharge port with a control valve is provided at the bottom of the installation cylinder. In this rock crushing device for geological exploration, the ore to be crushed is placed into the installation cylinder from the feed port, and the primary crushing part inside the installation cylinder can perform the first crushing treatment on the ore, and then the ore after the first crushing enters the installation cylinder, and the secondary crushing part in the installation cylinder can perform the second crushing treatment on the ore, so that the ore is crushed more completely, and at the same time, the protective door can play a protective role when the ore is squeezed and crushed by two gear rollers and splashed.

[0004] However, in actual use, the device will indiscriminately re-crush the crushed ore. Some ores with qualified particle sizes will be crushed again to make their particle sizes finer. Although over-crushing of the ore will promote full mineral dissociation, it will also produce more fine particles that are difficult to select, causing mineral loss, that is, the "over-crushing" phenomenon.

[0005] Therefore, it is necessary to design a rock crushing device for geological exploration, which can recover and crush the ore with too large particle size again, and screen the ore with qualified particle size in advance. Utility Model Content

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] like Figure 1 and Figure 2 As shown, the utility model provides a technical solution: a stone crushing device for geological exploration, comprising a base plate 1, a stone crushing mechanism 2 is provided at the front upper end of the base plate 1, and a recovery mechanism 5 is provided at the rear upper end of the base plate 1. When working, the ore to be crushed is firstly put into the upper side of the stone crushing mechanism 2, and the stone crushing mechanism 2 will crush and screen the stone when working. After screening, the ore with a larger particle size will fall into the recovery mechanism 5, and the recovery mechanism 5 will work and put it back into the stone crushing mechanism 2 for secondary crushing. A driving motor 3 is fixedly installed on one side of the upper end of the base plate 1 corresponding to the stone crushing mechanism 2 through a mounting rod.

[0035] Specifically, Figure 3 and Figure 4 As shown, the stone crushing mechanism 2 includes a shell 21 installed on the upper end of the base plate 1 through a plurality of support rods, and a shroud 22 is fixed on the upper end of the shell 21, and the shroud 22 can prevent the ore from being squeezed out when it falls and is crushed. Two front-to-rear distributed stone crushing tooth rollers 23 are provided between the left and right side walls of the inner cavity of the shell 21, and the left and right sides of the axes of the two stone crushing tooth rollers 23 pass through the outer wall of the shell 21, and the axes of the two stone crushing tooth rollers 23 are fixedly connected with gears 4 on the side close to the driving motor 3, and the two gears 4 are meshed, and the output end of the driving motor 3 is fixedly connected to the gear 4 located at the rear side. The stone crushing tooth roller 23 is a prior art. When the driving motor 3 is working, it will drive one of the stone crushing tooth rollers 23 to rotate continuously, and make the other stone crushing tooth roller 23 rotate in the opposite direction through the gear 4. When the two stone crushing tooth rollers 23 rotate in opposite directions (such as Figure 3 The tooth grooves on its surface can crush and crush the materials.

[0036] Furthermore, the lower end of the shell 21 is inclined, and the lower parts of the left and right side walls of the inner surface of the shell 21 are provided with inclined chutes 28, and a screening plate 27 is slidably installed between the two chutes 28, and the ore crushed by the crushing tooth roller 23 will fall on the screening plate 27, and a receiving box 6 is fixedly installed at the upper end of the bottom plate 1 corresponding to the position of the screening plate 27, and rotating rods 24 are rotatably installed on the left and right sides of the lower front end of the shell 21, and the ends of the two rotating rods 24 that are away from each other are connected to the shafts of the crushing tooth roller 23 on the front side by belts, so that the crushing tooth roller 23 on the front side will drive the two rotating rods 24 to rotate synchronously when rotating, and the ends of the two rotating rods 24 that are close to each other are An offset rod 25 is fixedly connected, and one end of the two offset rods 25 away from the rotating rod 24 is rotatably connected to a swing rod 26. One end of the two swing rods 26 away from the offset rod 25 is rotatably connected to the front end of the screening plate 27. When the rotating rod 24 rotates, it will drive the offset rod 25 to rotate synchronously, so that the offset rod 25 will pull the swing rod 26 back and forth, allowing the screening plate 27 to swing back and forth in the chute 28, so that the crushed ore can be screened through the sieve holes on the surface of the screening plate 27, and the crushed ore with qualified particle size will pass through the sieve holes and fall into the receiving box 6, while the crushed ore with too large particle size will fall backward along the inclined screening plate 27 into the recovery mechanism 5, thereby achieving the effect of screening the ore with qualified particle size in advance.

[0037] In order to secondary crush the oversized ore, Figure 5 - Fig.11 As shown, the recovery mechanism 5 includes a placing table 51, and a placing groove 510 is opened at the upper end of the placing table 51. The crushed ore with large particle size screened by the screening plate 27 will fall into the placing groove 510. The upper end of the placing table 51 is fixedly installed with an inverted L-shaped clamping plate 52 on both sides. The front end of the horizontal part of the clamping plate 52 is located at the opening of the enclosure 22. A plurality of guide components 53 arranged along the edge contour of the clamping plate 52 are provided between the two clamping plates 52, that is, Figure 5 As shown, each guide assembly 53 corresponds to a right angle on the inner side of the clamp plate 52, and each guide assembly 53 is composed of a guide shaft rotatably mounted between the two guide assemblies 53 and toothed belt pulleys fixed at both ends of the guide shaft. A guide rail 54 is provided at a position corresponding to a 270° angle on the inner side of the two clamp plates 52 that are close to each other, and the guide rail 54 is fixedly connected to the clamp plate 52 on the other side.

[0038] Furthermore, a toothed synchronous belt 55 is wound together between the outer surfaces of multiple toothed pulleys located on the same side, and the toothed synchronous belt 55 passes through the guide rail 54 on the corresponding side. A first dual-axis motor 56 is installed in the middle of the outer surface of the guide shaft of one of the guide components 53. The lower end of the first dual-axis motor 56 is provided with a mounting plate installed between the two clamping plates 52. The two output ends of the first dual-axis motor 56 are fixedly connected to the guide shaft of the corresponding guide component 53. The outer surfaces of the two toothed synchronous belts 55 are each provided with a mounting block 57 on one side close to each other. The mounting block 57 is connected to the corresponding toothed synchronous belt. The belt 55 is fixed, and a connecting plate 58 is fixedly installed between the two mounting blocks 57. A recovery shovel 59 is provided at one end of the connecting plate 58 away from the toothed synchronous belt 55. The recovery shovel 59 can pour the crushed ore in the placement groove 510 into the outer shell 21 along the trajectory of the toothed synchronous belt 55 for re-crushing and recovery. Therefore, when the first dual-axis motor 56 is working, the toothed synchronous belt 55 will be driven to rotate through a plurality of guide components 53, so that the recovery shovel 59 will first shovel up the crushed ore in the placement groove 510 along the trajectory of the toothed synchronous belt 55, and then move the recovery shovel 59 upward along the toothed synchronous belt 55.

[0039] It should be noted that if Figure 6 As shown, the two guide rails 54 respectively wrap around the sides of the outer surfaces of the two toothed synchronous belts 55 that are away from each other, and the two mounting blocks 57 are respectively fixed on the sides of the outer surfaces of the two toothed synchronous belts 55 that are close to each other. Therefore, when the mounting blocks 57 move with the toothed synchronous belts 55 and pass through the position of the guide rails 54, the two will not contact and collide.

[0040] In addition, if Figure 5 As shown, the distance from the connecting plate 58 to the lower end of the recovery shovel 59 needs to be designed based on actual distance measurement, so that the lower end of the recovery shovel 59 will move forward along the upper end surface of the inner cavity of the placement groove 510 without turning over.

[0041] like Figure 8 and Fig. 9 As shown, the recovery shovel 59 includes two connecting rods 591 fixedly mounted on one end of the connecting plate 58 away from the toothed synchronous belt 55, and the two connecting rods 591 are provided with a bucket support frame 593 at one end away from the connecting plate 58. The bucket support frame 593 is composed of two protruding blocks 595, two trapezoidal plates 596 and a transverse plate 597. The two protruding blocks 595 are rotatably connected to the connecting rods 591 on the corresponding side, the two trapezoidal plates 596 are fixedly connected to the side of the protruding blocks 595 on the corresponding side away from the connecting rod 591, and the transverse plate 597 is fixedly mounted between the two trapezoidal plates 596.

[0042] In addition, a supporting shovel 598 is installed for common rotation between the two trapezoidal plates 596, and a second double-axis motor 594 is fixedly installed in the middle of one end of the horizontal plate 597 away from the horizontal plate 597. The two output ends of the second double-axis motor 594 are fixedly connected to the output shaft passing through the corresponding trapezoidal plate 596 on one side, and the two output shafts are connected to the shaft of the supporting shovel 598 through a belt. When the recovery shovel 59 is located in the enclosure 22 (such as Figure 8 As shown in FIG. 1 , the second dual-axis motor 594 will work to rotate the shovel 598 through the principle of belt transmission, so that the shovel 598 is as shown in FIG. Fig. 9 The state is opened, and the crushed ore falls between the two crushing tooth rollers 23.

[0043] Furthermore, a rectangular baffle 592 is fixedly installed on the outer surface of the two connecting rods 591 away from the connecting plate 58. When the recovery shovel 59 moves along the toothed synchronous belt 55, the bucket bracket 593 is subjected to gravity so that the outer surface of the protruding block 595 is always in contact with the end surface of the rectangular baffle 592 away from the connecting plate 58, that is, Figure 5 - Fig.11 As shown in the working state, no matter which direction the two connecting rods 591 are flipped to along with the connecting plate 58, the protruding block 595 will be supported by the rectangular baffle plate 592 due to the overall gravity of the bucket frame 593. The purpose is to ensure that the bucket frame 593 will not shake and flip over to pour out the crushed ore on the upper end of the shovel 598 during the overall rising process, and when the bucket frame 593 returns to the initial position along the trajectory of the toothed synchronous belt 55, the trapezoidal plate 596 remains in a horizontal state and can work repeatedly.

[0044] The working principle of the utility model is as follows: the stone crushing device for geological survey, the driving motor 3 drives one of the stone crushing tooth rollers 23 to rotate continuously when working, and the gear 4 makes the other stone crushing tooth roller 23 rotate in the opposite direction. When the two stone crushing tooth rollers 23 rotate in the opposite direction, the tooth grooves on their surfaces can crush and crush the materials and drop them onto the screening plate 27;

[0045] The crushing tooth roller 23 located at the front side will drive the two rotating rods 24 and the offset rod 25 to rotate synchronously when rotating, so that the offset rod 25 will pull the swing rod 26 back and forth, so that the screening plate 27 can swing back and forth in the chute 28, so that the crushed ore can be screened through the sieve holes on the surface of the screening plate 27, and the crushed ore with qualified particle size will pass through the sieve holes and fall into the receiving box 6, while the crushed ore with too large particle size will fall backward along the inclined screening plate 27 into the recovery mechanism 5, so as to achieve the effect of screening the ore with qualified particle size in advance;

[0046] When the first dual-axis motor 56 is working, it will drive the toothed synchronous belt 55 to rotate through the multiple guide components 53, so that the recovery shovel 59 first scoops up the crushed ore in the placement groove 510 along the track of the toothed synchronous belt 55, and then move the recovery shovel 59 upward along the track of the toothed synchronous belt 55 until it enters the enclosure 22 and stops. At this time, the second dual-axis motor 594 will work to rotate the support shovel 598 through the principle of belt transmission, so that the support shovel 598 is as shown in FIG. Fig. 9 The state is opened, and the crushed ore falls between the two crushing tooth rollers 23 and is crushed again;

[0047] Finally, the recovery shovel 59 returns to the initial position along the trajectory of the toothed synchronous belt 55, and the above-mentioned work is repeated.

[0048] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
