Description

Technical Field

[0001] The invention belongs to the technical field of petroleum transportation, in particular to an automatic ball throwing device. Background Art

[0002] Oilfield pipelines are a vital component of the oil and gas industry. They play a key role in the production, transportation and distribution of oilfields. The oilfield pipeline system includes many types of pipelines, such as oil and gas gathering pipelines, oil and gas purification pipelines, water supply pipelines, sewage pipelines and water injection pipelines.

[0003] The automatic ball throwing device is a device used for wax removal in oil field pipelines. Its main function is to remove wax deposits on the wall of the oil pipeline by automatically throwing balls at a fixed time, thereby ensuring the normal flow and transportation efficiency of crude oil. This device has important application value in oil field production.

[0004] In the current prior art, when wax cleaning balls are dropped into oil field pipelines, since the diameter of the ball loading barrel is not much different from that of the wax cleaning balls, crude oil is easily brought into the ball loading barrel when the ball valve rotates, causing scaling of the barrel wall, and the balls sticking to each other and swelling, so that the wax cleaning balls are stuck in the loading barrel and cannot fall into the ball valve, affecting the effect of dropping the balls.

[0005] For this reason, the present invention provides a kind of automatic pitching device. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: an automatic ball-dropping device described in the present invention comprises a pump body, a support plate is fixedly installed at the bottom of the pump body, a ball-dropping cylinder is fixedly installed at the bottom of the support plate, the pump body is fixedly connected to the top of the ball-dropping cylinder through the support plate, a box body is fixedly installed on the top of the pump body, a ball storage box is fixedly installed at the middle position of the top of the box body, a placing funnel is fixedly installed on the top of the ball storage box, a ball-dropping assembly is arranged inside the pump body, the ball-dropping assembly comprises a plunger, the ball-dropping assembly is used to drive the wax-cleaning balls to be dropped through the plunger, an opening and closing assembly is arranged inside the box body, the opening and closing assembly is used to drive the wax-cleaning balls from the ball storage box to move into the pump body, a ball-lifting assembly is arranged inside the ball storage box, the ball-lifting assembly is used to lift the remaining wax-cleaning balls when one of the wax-cleaning balls moves from the ball storage box into the pump body, and a co-driving assembly is arranged inside the box body, the co-driving assembly is used to drive the ball-lifting assembly and the ball-dropping assembly to move synchronously; Before use, multiple wax cleaning balls are placed into the ball storage box in sequence through the placement funnel. When multiple wax cleaning balls are placed in the ball storage box, the installation of the wax cleaning balls is completed. When it is necessary to throw balls into the oil field pipeline, the plunger is driven by the ball throwing component to operate and the wax cleaning balls are dropped into the pipeline. When the ball throwing component is working, the ball throwing component drives the ball lifting component to work through the same driving component, so that when the ball throwing component is working, the ball lifting component scoops up the multiple wax cleaning balls in the ball storage box and lifts them upward to separate the multiple wax cleaning balls, so as to prevent the wax cleaning balls from stacking and causing the ball jam when the ball lifting component is performing the ball throwing operation. At the same time, by Multiple wax cleaning balls are scooped up and separated, and the wax cleaning balls can also be prevented from sticking to each other. When the ball lifting assembly scoops up and lifts multiple wax cleaning balls upward, the ball lifting assembly drives the opening and closing assembly to open, and a wax cleaning ball located at the bottom of the ball storage box will fall into the pump body for ball throwing assembly. When the ball throwing assembly drops the wax cleaning ball into the oil field pipeline through the ball dropping tube for reset, the ball throwing assembly drives the ball lifting assembly to reset, and the ball lifting assembly drives the opening and closing assembly to close while resetting, preventing the ball throwing assembly from driving crude oil into the ball storage box when resetting and throwing the ball, causing contamination in the ball storage box and affecting the throwing effect.

[0008] Preferably, the pitching assembly also includes a control actuator, which is fixedly installed on the top of the support plate, a support seat is fixedly installed on the top of the support plate, a motor is fixedly installed on the top of the support seat, one end of the control actuator is fixedly connected to one side of the motor, a rotating rod is fixedly installed on the output end of the motor, the inner wall of the pump body is symmetrically rotatably connected with an arc surface block, the plunger is placed between the two arc surface blocks, the outer wall of the plunger is symmetrically fixedly installed with connecting pieces, one end of the two connecting pieces is respectively slidably connected to the inner walls of the two arc surface blocks, a transmission wheel is fixedly installed on the outer wall of the rotating rod, a toothed plate is fixedly installed on the inner wall of the plunger, the teeth on the transmission wheel are connected to the teeth on the toothed plate The teeth are engaged, a groove block is fixedly installed on one side of the two arc surface blocks, a telescopic cylinder is fixedly installed on one end of the rotating rod, and moment rods are fixedly installed on both output ends of the telescopic cylinder. When throwing the ball, the telescopic cylinder first drives the two moment rods to be respectively inserted into the interior of the two groove blocks, so that the two arc surface blocks are integrated with the rotating rod through the two moment rods, and then the actuator is controlled to control the motor to rotate. When the motor rotates, it can drive the plunger and the arc surface block to rotate in the box body, so that the top end of the plunger rotates to the top of the ball drop barrel, so that the wax cleaning ball placed on the top of the plunger is dropped into the oil field pipeline through the ball drop barrel, which plays the role of throwing the ball.

[0009] Preferably, both ends of the plunger are fixedly mounted with ball pushing moment plates, and the outer walls of the two ball pushing moment plates can be slidably connected to the inner sides of the two arc surface blocks. When the motor drives the plunger to rotate to just above the ball dropping barrel, the motor drives the rotating rod to rotate, and the rotating rod drives the transmission wheel to rotate when it rotates. Since the transmission wheel and the toothed plate are in a meshing relationship, when the transmission wheel rotates, the transmission wheel drives the toothed plate to move, and the toothed plate will slide downward between the two arc surface blocks, and the ball pushing moment plate will slide against the inner walls of the two arc surface blocks to prevent the wax cleaning ball from being unable to be thrown out between the two arc surface blocks, thereby playing a role in assisting the ball throwing. At the same time, the ball pushing moment plate slides between the two arc surface blocks to prevent the oil in the oil pipeline from entering between the two arc surface blocks when the wax cleaning ball is thrown, causing scaling and blockage. The two ends of the plunger are symmetrically arranged. When one end of the plunger is placed just above the ball dropping barrel, the other end of the plunger will be placed just below the ball storage box.

[0010] Preferably, the ball lifting assembly includes a ball receiving rack, and there are two ball receiving racks. The two ball receiving racks are symmetrically arranged inside the ball storage box, and the space between the two ball receiving racks is used to place wax cleaning balls. The interior of the ball storage box is symmetrically provided with moving rack rods, and a plurality of ball lifting blocks are fixedly installed on the inner sides of the two moving rack rods. A pressure block is fixedly installed on one end of the two moving rack rods. The inner walls of the two ball receiving racks are provided with a plurality of through holes, and the outer walls of the plurality of ball lifting blocks are respectively slidably connected with the inner walls of the plurality of through holes, and one end of the two pressure blocks is an inclined sliding surface. When the motor drives the plunger to move between the two arc surface blocks, the motor pushes the two pressure blocks inward through the same drive assembly. When the two pressure blocks move inward, the pressure blocks It drives multiple ball lifting blocks to move into the ball receiving rack. When the motor drives the ball pushing moment plate to move to the bottom end between the two arc blocks, the multiple ball lifting blocks lift the multiple wax cleaning balls in the ball receiving rack through the through-holes to separate the multiple wax cleaning balls, thereby preventing the wax cleaning balls from stacking and jamming when loading the balls. At the same time, by scooping up and separating the multiple wax cleaning balls, it can also prevent the multiple wax cleaning balls from sticking to each other. Since the ball lifting block at the bottom is set at a distance from the bottom end of the ball receiving rack, when the multiple wax cleaning balls in the ball receiving rack are scooped up, the wax cleaning balls placed at the bottom end of the ball receiving rack cannot be scooped up, and the balls can be replenished for the next ball loading operation.

[0011] Preferably, a round rod is fixedly installed on the outer wall of the telescopic cylinder, and an electronic telescopic rod is slidably connected to the inner wall of one end of the round rod, and a rotating disk is fixedly installed on one end of the electronic telescopic rod. When the control actuator drives the top of the plunger to rotate to just above the ball falling cylinder, the telescopic cylinder drives the two torque rods to move out from the inside of the two slot blocks, and then controls the electronic telescopic rod to be inserted into the round rod, so that when the motor rotates, the motor can drive the rotating disk to rotate through the electronic telescopic rod, thereby playing the role of assembly transmission.

When the rotating disk rotates, the rotating disk drives the two axle rods to rotate through the transmission shaft and the belt. When the two axle rods rotate, the axle rods will drive the two push blocks to move on the threaded openings on the axle rods through threaded transmission, and the two push blocks will squeeze and push the two pressure blocks, thereby making the two moving rack rods move inward. While moving, multiple ball lifting blocks will shovel up the wax cleaning balls placed in the ball storage box, thereby playing a role of synchronous driving.

Two sets of return springs are symmetrically arranged between the inner wall of the box body and the outer walls of the two frame moving rods. The two sets of return springs are respectively placed on the outside of the two sets of sliding limit rods. When the push block moves from one end of the shaft rod to the other end, the pressure block will lose the limiting thrust, and the frame moving rod will return to its position driven by the elastic return force of the return spring, so that one end of the pressure block is returned to one side of the push block, which is convenient for the next scooping operation.

When multiple ball lifting blocks scoop up the wax cleaning balls, the two ball blocking blocks are fully opened at this time, and the wax cleaning balls at the bottom of the ball receiving rack will lose the limit of the ball blocking blocks, causing them to fall from the bottom of the ball receiving rack between the two arc blocks, thereby completing the ball loading operation. When the rack moving rod returns to its original position driven by the elastic reset force of the reset spring, the rack moving rod will push the gear to reverse, and the two ball blocking blocks will slide and close on the top of the pump body to prevent the arc blocks from bringing crude oil into the ball storage box when the control actuator drives the arc blocks to rotate, thereby avoiding scaling in the ball receiving rack and the wax cleaning balls from being unable to fall, thereby playing an oil blocking role.

[0015] Preferably, a controller is fixedly installed on one side of the ball storage box. Before work, by inputting the release time of the wax-removing balls into the system in the controller, the controller will control the device to release the wax-removing balls at a fixed time.

When multiple wax cleaning balls are placed in the ball storage box 3, the installation of the wax cleaning balls is completed. When it is necessary to throw balls into the oil field pipeline, the plunger 202 is driven by the ball throwing component to operate and the wax cleaning balls are thrown into the pipeline. When the ball throwing component is working, the ball throwing component drives the ball lifting component to work through the same driving component, so that when the ball throwing component is working, the ball lifting component scoops up the multiple wax cleaning balls in the ball storage box 3 and lifts them upward to separate the multiple wax cleaning balls, so as to prevent the wax cleaning balls from stacking and jamming when the ball lifting component is performing the ball throwing operation. At the same time, multiple wax cleaning balls are scooped up and separated. It can also prevent multiple wax cleaning balls from sticking to each other. When the ball lifting assembly scoops up multiple wax cleaning balls and lifts them upward, the ball lifting assembly drives the opening and closing assembly to open, and a wax cleaning ball located at the bottom end of the ball storage box 3 will fall into the pump body 2 for ball throwing assembly. When the ball throwing assembly drops the wax cleaning ball into the oil field pipeline through the ball dropping tube 7 for reset, the ball throwing assembly drives the ball lifting assembly to reset, and while the ball lifting assembly is reset, it drives the opening and closing assembly to close, preventing the ball throwing assembly from driving crude oil into the ball storage box 3 when resetting and throwing the ball, causing contamination in the ball storage box 3, affecting the throwing effect.

When the motor 6 rotates, it can drive the plunger 202 and the arc block 201 to rotate in the box body 1, so that the top end of the plunger 202 rotates to the top of the ball drop tube 7, so that the wax cleaning ball placed on the top end of the plunger 202 is dropped into the oil field pipeline through the ball drop tube 7, which plays the role of throwing the ball.

[0028] like Figure 6 to Figure 7 As shown, both ends of the plunger 202 are fixedly mounted with a ball push moment plate 203, and the outer walls of the two ball push moment plates 203 can be slidably connected with the inner sides of the two arc surface blocks 201; When the motor 6 drives the plunger 202 to rotate to the top of the ball-dropping cylinder 7, the motor 6 drives the rotating rod 601 to rotate, and the rotating rod 601 drives the transmission wheel 204 to rotate. Since the transmission wheel 204 and the tooth plate 205 are in meshing relationship, when the transmission wheel 204 rotates, the transmission wheel 204 drives the tooth plate 205 to move, and the tooth plate 205 will slide downward between the two arc blocks 201, and the ball-pushing moment plate 203 will slide against the inner wall of the two arc blocks 201. The two ends of the plunger 202 are symmetrically arranged. When one end of the plunger 202 is placed directly above the ball dropping tube 7, the other end of the plunger 202 will be placed directly below the ball storage box 3.

When the motor 6 drives the plunger 202 to move between the two arc blocks 201, the motor 6 pushes the two pressure blocks 305 to move inward through the same drive assembly. When the two pressure blocks 305 move inward, the pressure blocks 305 drive the multiple ball lifting blocks 307 to move into the ball receiving rack 301. When the motor 6 drives the ball pushing moment plate 203 to move to the bottom end between the two arc blocks 201, at this time, the multiple ball lifting blocks 307 lift the multiple wax cleaning balls in the ball receiving rack 301 through the through opening 309, so that Multiple wax cleaning balls are separated to prevent them from stacking and jamming when loading balls. At the same time, multiple wax cleaning balls are scooped up and separated to prevent them from sticking to each other. Since the ball lifting block 307 at the bottom is located at a distance from the bottom end of the ball receiving rack 301, when the multiple wax cleaning balls in the ball receiving rack 301 are scooped up, the wax cleaning balls placed at the bottom end of the ball receiving rack 301 cannot be scooped up, and balls can be replenished for the next ball loading operation.

[0031] like Figure 5 to Figure 6 As shown, the same drive assembly includes a shaft rod 101, the number of shaft rods 101 is two, both ends of the two shaft rods 101 are rotatably connected to the inner wall of the box body 1, the middle position of the two shaft rods 101 is provided with a threaded opening 102, the outer walls of the two threaded openings 102 are threadedly connected with push blocks 103, one end of the two push blocks 103 is an inclined sliding surface, one end of the two push blocks 103 can be slidably connected to one end of the two pressure blocks 305 respectively, one end of the two shaft rods 101 and one end of the indexing disk 106 are fixedly installed with a transmission shaft 105, and the inner walls of the three transmission shafts 105 are rotatably connected with a belt 104; When the rotating disk 106 rotates, the rotating disk 106 drives the two shafts 101 to rotate through the transmission shaft 105 and the belt 104. When the two shafts 101 rotate, through the threaded transmission, the shaft 101 will drive the two push blocks 103 to move on the threaded openings 102 on the shafts 101, and the two push blocks 103 will squeeze and push the two pressure blocks 305, thereby moving the two rack rods 304 inward. While moving, multiple ball lifting blocks 307 will scoop up the wax cleaning balls placed in the ball storage box 3, playing a role of synchronous driving. It should be noted here that the number of circles opened by the threaded opening 102 is the same as the number of circles rotated by the transmission wheel 204, and the number of circles rotated by the transmission wheel 204 and the number of teeth on the toothed plate 205 need to be obtained based on actual measurements.

[0032] like Figures 4 to 5 As shown, two groups of sliding limit rods 308 are fixedly installed on the inner wall of the ball storage box 3, and the inner walls of the two rack moving rods 304 are respectively slidably connected with the outer walls of the two groups of sliding limit rods 308. Two groups of return springs 306 are symmetrically arranged between the inner wall of the box body 1 and the outer walls of the two rack moving rods 304, and the two groups of return springs 306 are respectively placed outside the two groups of sliding limit rods 308; When the push block 103 moves from one end of the shaft 101 to the other end, the pressure block 305 will lose its limiting thrust, and the rack moving rod 304 will return to its original position under the drive of the elastic restoring force of the restoring spring 306, so that one end of the pressure block 305 is returned to one side of the push block 103, facilitating the next scooping operation.

[0033] like Figures 4 to 5 As shown, the opening and closing assembly includes a gear rod 303, and there are two gear rods 303. Ball-blocking blocks 302 are symmetrically arranged between the top of the pump body 2 and the inner wall of the box body 1. The outer walls of the two ball-blocking blocks 302 are slidably connected to the top inner wall of the pump body 2. One end of the two gear rods 303 is fixedly connected to the outer walls of the two ball-blocking blocks 302 respectively. Gears 3010 are symmetrically arranged on the inner wall of the box body 1. The teeth of the two gears 3010 are respectively meshed with the teeth on the two moving rack rods 304 and the gear rods 303. The outer walls of the two arc blocks 201 can be slidably connected to the bottoms of the two ball-blocking blocks 302. When the two pressure blocks 305 move inward, the rack moving rod 304 drives the gear rod 303 to move through the gear 3010, and the two gear rods 303 will move and open on the top inner wall of the pump body 2. When the multiple ball lifting blocks 307 scoop up the wax cleaning balls, the two ball blocking blocks 302 are fully opened, and the wax cleaning balls located at the bottom of the ball receiving rack 301 will lose the limit of the ball blocking block 302, causing them to fall from the bottom of the ball receiving rack 301 between the two arc blocks 201, thereby completing During the ball loading operation, when the rack moving rod 304 returns to its original position driven by the elastic restoring force of the restoring spring 306, the rack moving rod 304 will push the gear 3010 to reverse, and the two ball blocking blocks 302 will slide and close on the top of the pump body 2 to prevent the arc surface block 201 from bringing crude oil into the ball storage box 3 when the control actuator 5 drives the arc surface block 201 to rotate, thereby avoiding scaling in the ball receiving rack 301 and the phenomenon that the wax cleaning balls cannot fall off, thereby playing the role of blocking oil.

[0034] like Figure 1 to Figure 2 As shown, a controller 10 is fixedly mounted on one side of the ball storage box 3; Before operation, by inputting the time for releasing the wax-removing balls into the system of the controller 10, the controller 10 will control the device to release the wax-removing balls at a fixed time. The setting of the controller 10 plays the role of remote control of the timed release.

[0035] like Figures 5 to 8 As shown, a hydraulic cylinder 8 is fixedly installed on the other side of the ball storage box 3, and a strip board 801 is fixedly installed on the output end of the hydraulic cylinder 8. Connecting rods 802 are symmetrically fixedly installed on the outer walls of the two ball receiving racks 301. One end of the four connecting rods 802 is connected to the inner walls of the two strip boards 801 in pairs, and the bottom ends of the two ball receiving racks 301 are respectively slidably connected to the inner walls of the two ball blocking blocks 302; Before use, the hydraulic cylinder 8 is controlled to drive the strip plate 801 to move, so that the strip plate 801 drives the ball receiving rack 301 to move in the ball storage box 3 through the connecting rod 802, thereby adjusting the distance between the two ball receiving racks 301, and wax cleaning balls of different sizes can be placed between the two ball receiving racks 301, so that the device is suitable for placing wax cleaning balls on oil field pipelines of different sizes.

[0036] Working principle: Before use, multiple wax cleaning balls are placed in turn into the ball storage box 3 through the placement funnel 4. When multiple wax cleaning balls are placed in the ball storage box 3, the installation of the wax cleaning balls is completed. When it is necessary to throw balls into the oil field pipeline, the plunger 202 is driven by the ball throwing component to operate and the wax cleaning balls are thrown into the pipeline. When the ball throwing component is working, the ball throwing component drives the ball lifting component to work through the same driving component, so that when the ball throwing component is working, the ball lifting component scoops up the multiple wax cleaning balls in the ball storage box 3 and lifts them upward to separate the multiple wax cleaning balls, so as to prevent the wax cleaning balls from stacking and causing the ball jam when the ball lifting component is performing the ball throwing operation. By scooping up and separating the multiple wax cleaning balls, it is also possible to prevent the multiple wax cleaning balls from sticking to each other. When the ball lifting assembly scoops up the multiple wax cleaning balls and lifts them upward, the ball lifting assembly drives the opening and closing assembly to open, and a wax cleaning ball located at the bottom end of the ball storage box 3 falls into the pump body 2 for ball throwing. When the ball throwing assembly drops the wax cleaning ball into the oil field pipeline through the ball dropping tube 7 for reset, the ball throwing assembly drives the ball lifting assembly to reset, and the ball lifting assembly drives the opening and closing assembly to close while resetting, preventing the ball throwing assembly from driving the crude oil into the ball storage box 3 when resetting and throwing the ball, causing contamination in the ball storage box 3 and affecting the throwing effect. When throwing the ball, first, the telescopic cylinder 11 drives the two moment rods 13 to be respectively inserted into the interior of the two slot blocks 12, so that the two arc surface blocks 201 are integrated with the rotating rod 601 through the two moment rods 13, and then the actuator 5 is controlled to control the motor 6 to rotate. When the motor 6 rotates, it can drive the plunger 202 and the arc surface block 201 to rotate in the box body 1, so that the top of the plunger 202 rotates to the top of the ball drop tube 7, so that the wax cleaning ball placed on the top of the plunger 202 is dropped into the oil field pipeline through the ball drop tube 7, which plays the role of throwing the ball; When the motor 6 drives the plunger 202 to rotate to the top of the ball-dropping cylinder 7, the motor 6 drives the rotating rod 601 to rotate, and the rotating rod 601 drives the transmission wheel 204 to rotate. Since the transmission wheel 204 and the tooth plate 205 are in meshing relationship, when the transmission wheel 204 rotates, the transmission wheel 204 drives the tooth plate 205 to move, and the tooth plate 205 will slide downward between the two arc blocks 201, and the ball-pushing moment plate 203 will slide against the inner wall of the two arc blocks 201. The two ends of the plunger 202 are symmetrically arranged. When one end of the plunger 202 is placed directly above the ball drop tube 7, the other end of the plunger 202 is placed directly below the ball storage box 3. When the motor 6 drives the plunger 202 to move between the two arc blocks 201, the motor 6 pushes the two pressure blocks 305 to move inward through the same drive assembly. When the two pressure blocks 305 move inward, the pressure blocks 305 drive the multiple ball lifting blocks 307 to move into the ball receiving rack 301. When the motor 6 drives the ball pushing moment plate 203 to move to the bottom end between the two arc blocks 201, at this time, the multiple ball lifting blocks 307 lift the multiple wax cleaning balls in the ball receiving rack 301 through the through opening 309, so that The plurality of wax cleaning balls are separated to prevent the wax cleaning balls from stacking and jamming when loading the balls. At the same time, by shoveling up and separating the plurality of wax cleaning balls, it is also possible to prevent the plurality of wax cleaning balls from sticking to each other. Since the ball lifting block 307 at the bottom is disposed at a distance from the bottom end of the ball receiving rack 301, when the plurality of wax cleaning balls in the ball receiving rack 301 are shoveled up, the wax cleaning ball at the bottom end of the ball receiving rack 301 cannot be shoveled up, and the balls can be replenished for the next loading operation. When the actuator 5 is controlled to drive the top of the plunger 202 to rotate to the top of the ball-dropping cylinder 7, the telescopic cylinder 11 drives the two moment rods 13 to move out from the two slot blocks 12, and then the electronic telescopic rod 107 is controlled to be inserted into the round rod 14, so that when the motor 6 rotates, the motor 6 can drive the indexing plate 106 to rotate through the electronic telescopic rod 107, which plays the role of assembly transmission; When the rotating disk 106 rotates, the rotating disk 106 drives the two shafts 101 to rotate through the transmission shaft 105 and the belt 104. When the two shafts 101 rotate, the shafts 101 will drive the two push blocks 103 to move on the threaded openings 102 on the shafts 101 through thread transmission. The two push blocks 103 will squeeze and push the two pressure blocks 305, so that the two moving rack rods 304 move inward. While moving, multiple ball lifting blocks 307 will scoop up the wax cleaning balls placed in the ball storage box 3, playing a role of synchronous driving; When the push block 103 moves from one end of the shaft 101 to the other end, the pressure block 305 loses the limiting thrust, and the rack moving rod 304 returns to its original position under the elastic restoring force of the restoring spring 306, so that one end of the pressure block 305 is placed back to one side of the push block 103, which is convenient for the next scooping operation. When the two pressure blocks 305 move inward, the rack moving rod 304 drives the gear rod 303 to move through the gear 3010, and the two gear rods 303 will move and open on the top inner wall of the pump body 2. When the multiple ball lifting blocks 307 scoop up the wax cleaning balls, the two ball blocking blocks 302 are fully opened, and the wax cleaning balls located at the bottom of the ball receiving rack 301 will lose the limit of the ball blocking block 302, causing them to fall from the bottom of the ball receiving rack 301 between the two arc blocks 201, thereby completing During the ball loading operation, when the rack moving rod 304 returns to its original position driven by the elastic restoring force of the restoring spring 306, the rack moving rod 304 will push the gear 3010 to reverse, and the two ball blocking blocks 302 will slide and close on the top of the pump body 2 to prevent the arc surface block 201 from bringing crude oil into the ball storage box 3 when the control actuator 5 drives the arc surface block 201 to rotate, thereby avoiding scaling in the ball receiving rack 301 and the phenomenon that the wax cleaning balls cannot fall, thereby playing the role of oil blocking; Before working, by inputting the time of placing the wax-removing balls into the controller 10 system, the controller 10 will control the device to place the wax-removing balls at a fixed time. The setting of the controller 10 plays the role of remote control of the timed placement; By controlling the hydraulic cylinder 8 to drive the strip plate 801 to move, the strip plate 801 drives the ball receiving rack 301 to move in the ball storage box 3 through the connecting rod 802, thereby adjusting the distance between the two ball receiving racks 301, and different sizes of wax cleaning balls can be placed between the two ball receiving racks 301, making the device suitable for placing wax cleaning balls on oil field pipelines of different sizes.
