[0002] Mining machinery is machinery directly used for mineral mining and enrichment, including mining machinery and mineral processing machinery. When the existing mining machinery cylinders are working, sometimes the top force of one cylinder is not enough and multiple cylinders are needed to work. In addition, there is no connecting and fixing structure between the existing multiple cylinders, and the connection between the multiple cylinders is not strong enough.

[0003] As disclosed in Chinese patent announcement No. CN212899230U, a cylinder body for mining machinery is disclosed. When in use, the second connecting block is removed from the fixed block by removing the first bolt, the telescopic rod is placed in the inner groove, and oil is added to the inner groove. Then, the second connecting block is placed on the fixed block, and the first bolt is passed through the fourth threaded hole and inserted into the third threaded hole to fix the second connecting block to the rod and the fixed block. When two cylinders need to be connected together, the slider of one of the cylinder bodies is slid into the slide groove of the other cylinder body, and the second bolt is passed through the first threaded hole and the second threaded hole to fix the two cylinder bodies. If more cylinders are needed, the other cylinder is connected in the same way, which effectively realizes that the existing multiple cylinder bodies have a connection and fixing structure, and the multiple cylinder bodies can be fixedly spliced ​​to enhance the functionality of the cylinder body and increase the usability of the cylinder body. At the same time, the splicing method is simple, easy to operate, and saves time and effort.

[0004] However, the cylinder bodies for mining machinery in the above-mentioned applications are various, and the mining cylinders have different sizes and diameters, and the device can only splice cylinders of a specific size, and its scope of application is limited. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a kind of oil cylinder body for mining machinery. Utility Model Content

[0006] The purpose of the utility model is to provide a cylinder body for mining machinery to solve the problem of the cylinder body for mining machinery proposed in the above background technology, that there are many kinds of mining cylinders, and the sizes and diameters are also different, and the device can only splice cylinders of specific sizes, and the scope of application is limited.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cylinder body for mining machinery, comprising a splicing box and a cylinder body, a placement bin is provided inside the splicing box, the cylinder body is placed in the placement bin inside the splicing box, a plurality of groups of clamping devices are symmetrically arranged inside the splicing box, a splicing device is provided on one side of the splicing box, and a heat dissipation device is provided on the front of the splicing box.

The sliding cavity is opened on one side of the prevention bin inside the splicing box, the electromagnet is installed on the inner wall of the sliding cavity, the elastic rope is installed on one side of the electromagnet, the sliding rod is fixedly connected to the outer end of the elastic rope and is slidably connected to the inside of the sliding cavity, and the clamping block is fixedly connected to the outer end of the sliding rod.

[0009] A further improvement is that the slide rod is made of magnetic material. After the cylinder body is inserted into the placement bin in the splicing box, the splicing box is connected to an external power supply, and the electromagnet is energized. A repulsive force is generated between the electromagnet and the slide rod, thereby pushing the slide rod to slide out of the sliding cavity and clamping and fixing the cylinder body through the clamping block at its right end to adapt to cylinder bodies of different diameters, thereby improving the applicability of the device. A non-slip rubber pad is adhered to the outer surface of the clamping block. The provision of the non-slip rubber pad increases the friction between the clamping block and the cylinder body and improves the stability of the clamping.

[0010] A further improvement is that the splicing device includes a splicing block, a splicing groove, a through hole, a fixing rod, and a fastening spring, the splicing block is fixedly connected to the right outer surface of the splicing box, the splicing groove is opened on the left outer surface of the splicing box, the through hole is opened at the top left side of the front of the splicing box and is communicated with the splicing groove, the fixing rod is inserted into the inside of the through hole, and the fastening spring is installed around the outer surface of the fixing rod.

Subsequently, the splicing block on the right side of another splicing box is inserted into the splicing groove on the left side of the first splicing box. The fixing rod is then released, and the fastening spring is reset under the action of its own elasticity, thereby pushing the fixing rod to insert into the inside of the through hole on the splicing block, thereby splicing and fixing the two splicing boxes, and then splicing and fixing multiple cylinder bodies, thereby enhancing the functionality of the cylinder bodies.

[0012] A further improvement is that the front and rear ends of the splicing box are respectively fixedly connected with fixed ear plates, and a threaded hole is opened through the center of the upper surface of the fixed ear plate. The internal thread of the threaded hole is connected with a ground drilling screw. Because most mines are mountainous and the use environment of the cylinder body may not be flat, when the cylinder body is placed, the ground drilling screw is screwed to drill into the ground along the threaded hole on the fixed ear plate, thereby fixing the splicing box and the cylinder body inside it to prevent it from tipping over and being damaged.

[0013] A further improvement is that the heat dissipation device includes a heat dissipation port, a breathable net, and a magnet block, the heat dissipation port is opened at the front center of the splicing box, the breathable net is installed inside the heat dissipation port, and the magnet block is fixedly connected to the bottom of the breathable net.

[0014] A further improvement is that a plug-in slot is provided at the front end of the upper surface of the splicing box, which is communicated with the heat dissipation port and extends to the inside of its bottom. A magnet block is also installed at the inner bottom of the plug-in slot. The breathable net is plugged into the inside of the plug-in slot. When the cylinder body is in use, a certain amount of heat is generated, and the cylinder body is cooled through the heat dissipation port. The breathable net is set to prevent small animals from drilling into the inside of the splicing box along the heat dissipation port, and will not affect the ventilation and heat dissipation. After long-term use, the breathable net can be pulled out from the inside of the plug-in slot for cleaning. After cleaning, the breathable net is inserted into the inside of the plug-in slot. The magnet block at the bottom of the breathable net and the magnet block at the bottom of the plug-in slot attract each other, thereby fixing the breathable net to prevent the breathable net from falling easily.

[0016] 1. The oil cylinder body for mining machinery, after the oil cylinder body is inserted into the placement bin in the splicing box, the splicing box is connected to an external power supply, and the electromagnet is energized, a repulsive force is generated between the electromagnet and the slide bar, thereby pushing the slide bar to slide out from the inside of the sliding cavity and clamping and fixing the oil cylinder body through the clamping block at its right end, so as to adapt to oil cylinder bodies of different diameters, thereby improving the application range of the device.

[0017] 2. When multiple cylinder bodies of the mining machinery cylinder need to be spliced ​​together for use, pull the fixing rod to slide it from the inside of the through hole to the outside and squeeze the fastening spring, then insert the splicing block on the right side of another splicing box into the splicing groove on the left side of the first splicing box, and then release the fixing rod.
