Description
Technical Field
[0001] This utility model relates to the technical field of three-way unloading valves, specifically a structure for a bearing seat of a three-way valve shaft of a belt unloading trolley. Background Technology
[0002] In modern industrial production, the three-way unloading valve of the belt unloading trolley plays a key role in material diversion and is widely used in many industries such as mining, chemical, and metallurgy. It can accurately allocate materials to different conveying paths according to production needs, greatly improving production efficiency and logistics rationality. In the process of ore mining and transportation, the three-way unloading valve of the belt unloading trolley can transport the mined ore to different processing production lines or storage areas according to factors such as ore grade and type, ensuring the efficient operation of subsequent processing procedures.
[0003] However, in the existing conventional batching trolley three-way unloading valve structure, the horizontal bearing seat of the three-way unloading valve flap shaft is usually designed to be embedded in the housing. In actual use, this structure generates a lot of dust during the batching process of the three-way unloading valve. The raw material dust can easily enter the horizontal bearing seat, resulting in poor bearing lubrication and low lubricating grease storage, which seriously affects the service life of the three-way unloading valve shaft bearing. Moreover, the existing horizontal bearing housing of this type has a compact structure. When it is necessary to replace, maintain or lubricate the horizontal bearing housing, due to its small structural space, it is necessary to open the three-way unloading valve body to carry out the operation. The process of replacing the horizontal bearing housing is cumbersome and complicated, which not only consumes a lot of time and labor costs, but also affects the working efficiency of the unloading trolley. Utility Model Content
[0004] The purpose of this utility model is to provide a bearing housing structure for the three-way valve shaft of a belt unloading trolley, which improves the lubrication efficiency of the device and ensures good bearing operation through the cooperation of auxiliary mechanisms. By modifying the position of the internal components of the drive mechanism, the operating space for workers can be increased, thereby improving maintenance efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a bearing housing structure for a three-way valve shaft of a belt unloading trolley, comprising a three-way unloading valve, and further comprising: A first bracket is fixedly connected to the surface of the three-way unloading valve, and a second bracket is fixedly connected to the surface of the three-way unloading valve; A drive mechanism for providing power is mounted on the surface of the first bracket, and an auxiliary mechanism is mounted on the surface of the drive mechanism.
[0006] Preferably, the driving mechanism includes an electro-hydraulic actuator rotatably connected to the surface of the first bracket, a horizontal bearing seat fixedly connected to the surface of the second bracket, a main shaft rotatably connected to the inner wall of the horizontal bearing seat, a first connecting rod fixedly connected to the surface of the main shaft, and a flap fixedly connected to the inner wall of the main shaft.
[0007] Preferably, the auxiliary mechanism includes a lubrication hole opened inside the horizontal bearing housing, a lubrication cylinder sleeved on the inner wall of the lubrication hole, a pressure rod fixedly connected to the surface of the main shaft, a blocking block fixedly connected to the top of the horizontal bearing housing, and a cleaning mechanism installed at the bottom of the pressure rod.
[0008] Preferably, the cleaning mechanism includes a second connecting rod fixedly connected to the bottom of the pressure rod, and a scraper is inserted into one end of the second connecting rod.
[0009] Preferably, the upper part of the lubrication cylinder is made of silicone, and the connection between the lubrication cylinder and the lubrication hole is made of polypropylene.
[0010] Preferably, the horizontal bearing housing is located outside the three-way discharge valve, and a sealing device is also provided at the connection between the three-way discharge valve and the main shaft.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, by modifying the position of the internal components of the drive mechanism, fundamentally avoids the impact of dust generated inside the three-way unloading valve on the lubrication of the device during use. At the same time, this adjustment increases the operating space for operators, improves maintenance efficiency, and with the cooperation of the auxiliary mechanism, when the three-way unloading valve is diverting material, the components inside the auxiliary mechanism can lubricate and clean the device, thereby eliminating the need for manual lubrication, improving the lubrication efficiency of the device, ensuring the good operation of the bearings, and extending the service life of the device. This solves the problems of difficult disassembly and assembly and poor lubrication caused by the installation location and structural form of existing devices. Attached Figure Description

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0015] Please see Figure 1-5 As shown, a three-way valve shaft bearing housing structure for a belt unloading trolley includes a three-way unloading valve 1. The three-way unloading valve 1 is installed at the unloading point of the belt trolley and has two independent material flow channels inside for diverting materials.
[0016] The surface of the three-way unloading valve 1 is fixedly connected to a first bracket 2, and the surface of the three-way unloading valve 1 is fixedly connected to a second bracket 3. There are two second supports 3, which are symmetrically distributed on both sides of the three-way unloading valve 1.
[0017] The surface of the first bracket 2 is equipped with a drive mechanism 4 for providing power. The drive mechanism 4 includes an electro-hydraulic actuator 41 rotatably connected to the surface of the first bracket 2. The surface of the second bracket 3 is fixedly connected to a horizontal bearing seat 42. The inner wall of the horizontal bearing seat 42 is rotatably connected to a main shaft 43. The surface of the main shaft 43 is fixedly connected to a first connecting rod 44. The other end of the first connecting rod 44 is rotatably connected to the electro-hydraulic actuator 41. The inner wall of the main shaft 43 is fixedly connected to a flap 45. The horizontal bearing housing 42 is located outside the three-way discharge valve 1 to prevent dust generated during the discharge process from corroding the horizontal bearing housing 42 and affecting the lubrication and service life of the internal bearing. At the same time, a sealing device is also provided at the connection between the three-way discharge valve 1 and the main shaft 43 to prevent material from leaking out from the connection gap between the two, thereby isolating dust. Material diversion is achieved through the cooperation of electro-hydraulic actuator 41 and first connecting rod 44. When the electro-hydraulic actuator 41 is activated, it pushes the first connecting rod 44 to rotate along the axis of the main shaft 43. During this process, the main shaft 43 drives the flap 45 on its surface to rotate. At this time, the flap 45 blocks the two flow channels of the three-way discharge valve 1 according to the direction of rotation, so that the material inside the three-way discharge valve 1 flows into the designated flow channel as required. An auxiliary mechanism 5 is mounted on the surface of the drive mechanism 4. The auxiliary mechanism 5 includes four lubrication holes 51 opened inside the horizontal bearing housing 42, which are evenly and symmetrically distributed inside the two horizontal bearing housings 42. A lubrication cylinder 52 is sleeved on the inner wall of the lubrication hole 51, and the lubrication cylinder 52 stores lubricating oil. Two pressure rods 53 are fixedly connected to the surface of the main shaft 43, which are distributed on both sides of the main shaft 43. Four blocking blocks 54 are fixedly connected to the top of the horizontal bearing housing 42, which are distributed on the top of the horizontal bearing housing 42 respectively. A cleaning mechanism 55 is installed at the bottom of the pressure rod 53. The cleaning mechanism 55 includes a second connecting rod 551 fixedly connected to the bottom of the pressure rod 53. One end of the second connecting rod 551 is inserted with a scraper 552 for scraping off the lubricating oil remaining at the bottom of the horizontal bearing seat 42.
[0018] The upper part of the lubrication cylinder 52 is made of silicone, which has good compressibility. The connection between the lubrication cylinder 52 and the lubrication hole 51 is made of polypropylene and is connected by injection molding. This ensures the sealing of the lubrication cylinder 52 to prevent lubricating oil leakage, and also ensures that it has sufficient compressibility to facilitate subsequent extrusion and oil injection. The scraper 552 adopts a V-shaped structure design, and its length is slightly longer than the thickness of the bottom of the horizontal bearing housing 42. This design can guide the lubricating oil remaining on the bottom surface of the horizontal bearing housing 42, making it convenient for subsequent collection. With the cooperation of the pressure rod 53 and the blocking block 54, when the main shaft 43 rotates, the pressure rod 53 rotates synchronously. When the pressure rod 53 rotates to contact the lubrication cylinder 52, the lubricating oil inside the lubrication cylinder 52 is squeezed into the bearing inside the horizontal bearing seat 42 under the cooperation of the pressure rod 53 and the blocking block 54, thereby realizing automatic lubrication of the bearing. At the same time, the scraper 552 at the bottom of the pressure rod 53 and the second connecting rod 551 rotate synchronously with the pressure rod 53. At this time, the top of the scraper 552 slides along the bottom of the horizontal bearing seat 42 to scrape off the residual lubricating oil at the bottom of the horizontal bearing seat 42, thereby preventing the residual lubricating oil from deteriorating due to long-term storage and causing failure of the horizontal bearing seat 42. Under the action of the V-shaped structure of the scraper 552, the scraped lubricating oil is guided into the collection bucket at its bottom.
[0019] It is worth noting that the technical features such as the electro-hydraulic actuator 41 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.
[0020] Working principle: First, the electro-hydraulic actuator 41 rotating on the surface of the first support 2 is activated, thereby pushing the first connecting rod 44 to rotate along the axis of the main shaft 43. This, in turn, drives the main shaft 43 and the flap 45 to rotate synchronously. The flap 45 blocks a flow channel inside the three-way unloading valve 1 according to the direction of rotation, thereby diverting the material to the designated flow channel as required. At the same time, the main shaft 43 drives the pressure rod 53 to rotate synchronously during rotation. When the pressure rod 53 rotates to contact the lubrication cylinder 52, it squeezes the lubrication cylinder 52 with the cooperation of the blocking block 54. The lubricating oil is squeezed into the interior of the horizontal bearing seat 42, thereby achieving automatic lubrication. At the same time, the second connecting rod 551 and the scraper 552 rotate synchronously with the pressure rod 53. The top of the scraper 552 slides along the bottom of the horizontal bearing seat 42 and scrapes off the residual lubricating oil. Under the action of the V-shaped structure, the scraped lubricating oil is guided to the collection bucket to prevent the residual lubricating oil from deteriorating and causing the horizontal bearing seat 42 to malfunction. Finally, if it is necessary to change the direction of the flap 45 to change the material flow direction inside the three-way discharge valve 1, simply reset the push rod of the three-way discharge valve 1.
[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
