Description

Technical Field

[0001] This invention relates to the field of mining machinery components technology, and in particular to a half-drum for mining machinery. Background Technology

[0002] Mining machinery refers to machinery directly used in mineral extraction and washing operations, including mining machinery and mineral processing machinery. The semi-drum is a crucial component for the transmission of mining machinery. Existing semi-drums typically consist of two cylinders joined together and secured with multiple bolts. However, the use of multiple bolts makes disassembling the semi-drum cumbersome and time-consuming. Replacing its components also requires significant time, severely reducing work efficiency. Therefore, a new semi-drum for mining machinery needs to be designed.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art and to propose a semi-drum for mining machinery.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A semi-drum for mining machinery includes two cylinders. Grooves are formed at both the upper and lower ends of each cylinder. Two connecting columns are fixedly installed on the side walls of each cylinder. Two connecting slots are formed on the side walls of each cylinder, and each connecting slot mates with a corresponding connecting column. Each connecting column has a positioning slot, and each connecting slot has a moving slot on its side wall. A positioning rod is slidably connected within each moving slot, and each positioning rod mates with a corresponding positioning slot. Control mechanisms are installed on both cylinders, and the two control mechanisms mate with the corresponding two positioning rods.

[0006] In the aforementioned half-drum for mining machinery, the control mechanism consists of a rotating hole and a bidirectional lead screw. The rotating hole is located between two moving slots, and the bidirectional lead screw is rotatably connected to the rotating hole. Both ends of the bidirectional lead screw are threadedly connected to two positioning rods, respectively.

[0007] In the aforementioned semi-drum for mining machinery, receiving grooves are provided on the side walls of the two connecting grooves, and push rods are slidably connected in the two receiving grooves. Springs are installed between the two push rods and the two receiving grooves, and a drive mechanism is installed between the bidirectional lead screw and the two push rods.

[0008] In the aforementioned semi-drum for mining machinery, the driving mechanism comprises a rotating rod, a connecting hole, a communicating groove, a driving gear, a connecting gear, two fixed racks, two mounting holes, and two fixed gears. The two fixed racks are respectively fixedly mounted on the side walls of the two push rods. The two mounting holes are respectively opened on the side walls of the two receiving grooves. The connecting hole is opened between the two mounting holes. The rotating rod is rotatably connected to the connecting hole. The two fixed gears are respectively fixedly mounted on one end of the rotating rod located in the two mounting holes, and the two fixed gears mesh with the corresponding fixed racks. The communicating groove is opened between the connecting hole and the rotating hole. The driving gear is fixedly mounted on one end of the rotating rod located in the communicating groove. The connecting gear is fixedly mounted on one end of the bidirectional lead screw located in the communicating groove, and the connecting gear meshes with the driving gear.

[0009] In the aforementioned half-drum for mining machinery, the tooth pitch of the connecting gear is equal to the tooth pitch of the driving gear, the diameter of the connecting gear is smaller than the diameter of the driving gear, and the number of teeth of the connecting gear is smaller than the number of teeth of the driving gear.

[0010] In the aforementioned semi-drum for mining machinery, pull rods are fixedly installed on the side walls of the two push rods away from the connecting column. Movable holes are provided on the side walls of the two receiving grooves, and each of the two movable holes cooperates with one of the two pull rods. A connecting rod is fixedly installed between the two pull rods. A control groove is provided between the two movable holes, and the control groove cooperates with the connecting rod. A screw is rotatably connected to the cylinder body, and one end of the screw located in the control groove is threadedly connected to the connecting rod. A knob is fixedly installed on the other end of the screw located outside the cylinder body, and an arc-shaped groove is provided on the cylinder body to cooperate with the knob.

[0011] In the aforementioned half-drum for mining machinery, the connecting column, positioning rod, and push rod are all made of hard metal materials.

[0012] Compared with existing technologies, the advantages of this invention are: 1. By using the connecting column, connecting groove, positioning groove and positioning rod, the fixed connection between the two cylinders can be achieved without the use of bolts. The installation method is relatively simple, which can save a lot of time required to install the half roller and improve the work efficiency during installation.

[0013] 2: Through the cooperation of the control mechanism and the drive mechanism, when the two cylinders are aligned, the positioning rod can be automatically inserted into the positioning groove to achieve self-locking of the two cylinders, which can effectively ensure the firmness and requires no additional operation, making it easy to use.

[0014] 3: By cooperating with the screw, connecting rod and pull rod, the positioning rod can be separated from the positioning groove when the knob is turned. At this time, the two cylinders can be easily separated. The operation is simple and does not require a lot of time, which can effectively improve the work efficiency during disassembly.

[0015] 4: By designing the dimensions of the drive gear and the connecting gear, the rotating rod only needs to rotate a few times to make the bidirectional lead screw rotate a lot. Therefore, the depth of the receiving groove does not need to be set too large so that the positioning rod can be smoothly inserted from the moving groove into the positioning groove. Thus, the size of the positioning groove on the connecting column does not need to be set too large, which can improve the connection stability between it and the positioning rod.

[0016] In summary, this invention achieves a fixed connection between two cylinders without the need for bolts through the cooperation of connecting columns, connecting grooves, positioning grooves, and positioning rods. Furthermore, with the cooperation of the control mechanism and the drive mechanism, when the two cylinders are aligned, the positioning rod automatically inserts into the positioning groove, achieving self-locking of the two cylinders. The disassembly and assembly of this half-roller is simple, does not require a lot of time, effectively improves work efficiency, and effectively ensures a high degree of security.

[0019] 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.

[0020] Reference Figure 1-5 A semi-drum for mining machinery includes two cylinders 1. Grooves 2 are provided at both the upper and lower ends of the two cylinders 1. Two connecting columns 3 are fixedly installed on the side walls of the two cylinders 1. Two connecting grooves 4 are provided on the side walls of the two cylinders 1, and each connecting groove 4 is respectively matched with the corresponding connecting column 3. It is worth noting the above: 1. From Figure 1 As can be clearly seen, the cylinder 1 on the left has two connecting columns 3 installed at its front end, and the cylinder 1 on the right has two connecting columns 3 installed at its rear end. The purpose of the staggered installation positions of the multiple connecting columns 3 is to ensure that the stress points of the two cylinders 1 after connection are not in the same direction, thereby improving the stability of the two cylinders 1 after connection.

[0021] 2. Each connecting post 3 is provided with a positioning groove 5, and each connecting groove 4 is provided with a moving groove 7 on its side wall. Each moving groove 7 is slidably connected with a positioning rod 6, and each positioning rod 6 cooperates with the corresponding positioning groove 5. When the connecting post 3 is inserted into the connecting groove 4, the positioning rod 6 is inserted into the positioning groove 5, which can fix the two cylinders 1. At this time, there is a lateral and longitudinal connecting force between the two cylinders 1, and the fixing effect can be effectively ensured.

[0022] 3. Both cylinders 1 are equipped with control mechanisms, and each control mechanism is engaged with a corresponding positioning rod 6. The control mechanism consists of a rotating hole 8 and a double-acting screw 9. The rotating hole 8 is located between two moving slots 7. The double-acting screw 9 is rotatably connected to the rotating hole 8, and both ends of the double-acting screw 9 are threadedly connected to the two positioning rods 6. When the double-acting screw 9 rotates, the two positioning rods 6 can move closer or further away from each other, thereby controlling whether the connecting column 3 and the connecting slot 4 are fixed.

[0023] 4. Each of the two connecting grooves 4 has a receiving groove 10 on its side wall, and each of the two receiving grooves 10 is slidably connected with a push rod 11. A spring 12 is installed between each of the two push rods 11 and the two receiving grooves 10. When the connecting post 3 is inserted into the connecting groove 4, it will apply a pushing force to the push rod 11, so that it overcomes the elastic force of the spring 12 and enters the receiving groove 10.

[0024] 5. A drive mechanism is installed between the bidirectional lead screw 9 and the two push rods 11. The drive mechanism consists of a rotating rod 15, a connecting hole 17, a connecting groove 18, a drive gear 19, a connecting gear 20, two fixed racks 13, two mounting holes 14, and two fixed gears 16.

[0025] 6. Two fixed racks 13 are respectively fixedly installed on the side walls of two push rods 11. Two mounting holes 14 are respectively opened on the side walls of two receiving grooves 10. A connecting hole 17 is opened between the two mounting holes 14. A rotating rod 15 is rotatably connected to the connecting hole 17. Two fixed gears 16 are respectively fixedly installed on one end of the rotating rod 15 located in the two mounting holes 14, and the two fixed gears 16 respectively mesh with the corresponding fixed racks 13. A connecting groove 18 is opened between the connecting hole 17 and the rotating hole 8. A drive gear 19 is fixedly installed on one end of the rotating rod 15 located in the connecting groove 18. A connecting gear 20 is fixedly installed on the bidirectional lead screw 9 located in the connecting groove 18. One end is connected to the connecting gear 20, which meshes with the drive gear 19. When the connecting pin 3 is inserted into the connecting groove 4, causing the push rod 11 to move to the receiving groove 10, the fixed rack 13 on the push rod 11 will drive the fixed gear 16 meshing with it to rotate. At this time, the rotating rod 15 will rotate at the same time. Then, with the cooperation of the drive gear 19 and the connecting gear 20, the bidirectional lead screw 9 can rotate at the same time, so that the two positioning rods 6 move away from each other and are inserted into the two positioning grooves 5 respectively. Therefore, the connection and fixation between the two cylinders 1 does not require additional operation. It is only necessary to align the two cylinders 1. After alignment, the two cylinders 1 achieve self-locking, which can effectively ensure the firmness.

[0026] 7. The connecting column 3, positioning rod 6 and push rod 11 are all made of hard metal material (hard metal material can be alloy steel material). The use of hard metal material can effectively ensure the strength of each connection and drive component on the half roller and ensure the stability of the connection.

[0027] 8. The tooth pitch of the connecting gear 20 is equal to the tooth pitch of the driving gear 19. The diameter of the connecting gear 20 is smaller than the diameter of the driving gear 19, and the number of teeth of the connecting gear 20 is smaller than the number of teeth of the driving gear 19. The advantage of this size design is that the rotating rod 15 only needs to rotate a few times to make the bidirectional lead screw 9 rotate a lot. Therefore, the depth of the receiving groove 10 does not need to be set too large so that the positioning rod 6 can be smoothly inserted from the moving groove 7 into the positioning groove 5. Therefore, the size of the positioning groove 5 on the connecting column 3 does not need to be set too large, which can improve the connection stability between it and the positioning rod 6.

[0028] 9. A pull rod 21 is fixedly installed on the side wall of the two push rods 11 away from the connecting column 3. A moving hole 22 is provided on the side wall of each of the two receiving grooves 10, and the two moving holes 22 respectively cooperate with the two pull rods 21. A connecting rod 23 is fixedly installed between the two pull rods 21. A control groove 24 is provided between the two moving holes 22, and the control groove 24 cooperates with the connecting rod 23. A screw 25 is rotatably connected to the cylinder 1, and one end of the screw 25 located in the control groove 24 is threadedly connected to the connecting rod 23. The other end of the screw 25 located outside the cylinder 1 is fixedly installed with a screw... The knob 26 has an arc-shaped groove 27 on the cylinder 1 that matches the knob 26. When the two cylinders 1 need to be removed, rotating the knob 26 causes the screw 25 to drive the connecting rod 23 to move into the control groove 24. At this time, the two pull rods 21 will exert a force on the two push rods 11 to move out of the connecting groove 4. Therefore, under the operation of the drive mechanism, the bidirectional lead screw 9 can drive the two positioning rods 6 to move closer to each other, realizing the separation from the two connecting columns 3. At this time, the two cylinders 1 can be easily separated. The operation is simple and does not require a lot of time, which can effectively improve work efficiency.

[0029] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0030] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0031] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
