[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, the power component drives two pressing rollers to rotate eccentrically to crush the oil well cement material, and the rotation of the two internally threaded barrels and the thread thrust generated by the two threaded columns cause the internally threaded barrels to move along the axial direction of the threaded column, resulting in the axis of the pressing roller and the axis of the connecting shaft being not concentric, that is, the pressing roller rotates eccentrically along the axial direction of the connecting shaft, thereby adjusting the minimum distance between the two pressing rollers when rotating, which is convenient for crushing different particles of the oil well cement material, and the crushing is stable, and the adjusted crushing distance is not easy to change.

[0019] 2. In the present invention, the rotation of the pressure roller also drives the receiving plate and the elastic sheet to rotate together through the telescopic groove, and when the two pressure rollers rotate eccentrically and approach each other, the adjacent surfaces of the two adjacent receiving plates on the left and right will contact first, and as the pressure roller continues to rotate, the receiving plate slides toward the inside of the telescopic groove until the ends of the two receiving plates abut against each other, so that the dropped oil well cement material can be received, thereby preventing the dropped oil well cement material from passing directly between the two pressure rollers, thereby ensuring the fineness of the rolling of the oil well cement material, and as the two pressure rollers continue to rotate, the center of gravity moves away from each other from the closest position, and the left and right receiving plates that were previously in abutment gradually slide toward the periphery of the telescopic groove under the action of the rebound force of the elastic sheet until the ends of the receiving plates contact the inner wall of the rolling outer frame, and as the pressure roller rotates in the following process, the oil well cement material attached to the inner wall of the rolling outer frame is scraped off, thereby achieving the dual functions of receiving the material and cleaning the inner wall of the rolling outer frame.

[0020] 3. In the present invention, when the two pressure rollers rotate eccentrically to approach each other, the two feeding flaps of the feeding component flip downward to release the material, which is then crushed by the two pressure rollers approaching each other. In addition, when the two feeding flaps flip downward, the rotation of the wave cam and the rebound force of the oscillation spring cause the movable block to swing left and right along the inside of the slide slot to produce an oscillation effect, and the feeding flap is driven to oscillate together through the hinge shaft. The oscillation effect ensures that the oil well cement material on the feeding flap is released more thoroughly and cleanly.

[0021] 4. In the present invention, when the two pressure rollers rotate eccentrically away from each other, the first cam just ends the upward push on the guide wheel, the slide bar slides downward, and ends the upward push on the rocker arm through the connecting rod, and the resilience of the torsion spring pushes the hinge shaft and the feeding flap to rotate. After the two feeding flaps rotate, the adjacent surfaces contact each other, thereby interrupting the feeding. Therefore, when the two pressure rollers rotate eccentrically away from each other, no oil well cement material will pass through, avoiding the problem of insufficient crushing of the oil well cement material.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1 - Fig.11 The technical solution provided by the present invention specifically includes the following embodiments:

[0036] Embodiment 1: An oil well cement roller press comprises a fixed end plate 1, the number of the fixed end plates 1 is two, and the two fixed end plates 1 are distributed front and back, a rolling component 2 is fixedly arranged between the two fixed end plates 1, a feeding component 3 is arranged between the two fixed end plates 1, and the feeding component 3 is located on the top of the rolling component 2, wherein a power component 4 is fixedly arranged on the front side of a fixed end plate 1 located at the front, and two guide plates 5 symmetrically distributed on the left and right are fixedly installed between the two fixed end plates 1;

[0037] The rolling component 2 includes a rolling outer frame 201 fixedly installed between two front and rear fixed end plates 1, and two left and right distributed pressing rollers 202 are rotatably arranged inside the rolling outer frame 201, and the front sides of the pressing rollers 202 are penetrated with adjustment grooves 203, and the insides of the adjustment grooves 203 are slidably installed with adjustment blocks 204, and the front and back sides of the adjustment blocks 204 are fixedly installed with connecting shafts 205, and the connecting shafts 205 are rotatably connected with the two fixed end plates 1 respectively, and the inside of the adjustment block 204 is provided with two front and rear distributed transfer grooves 206, and the inside of the transfer groove 206 is rotatably installed with an internal threaded cylinder 207, and the internal thread of the internal threaded cylinder 207 is connected with a threaded column 208, and the threaded column 208 is fixedly installed between the top wall and the bottom wall of the adjustment groove 203;

[0038] The adjusting block 204 has two front-to-back placement grooves 209 disposed inside, and the placement grooves 209 are located outside the adapter groove 206. The adjusting block 204 has a first shaft hole 2011 disposed inside, and the first shaft hole 2011 is located between the front and back placement grooves 209. The lower part of the outer wall of the two internally threaded cylinders 207 is fixedly mounted with a first driven bevel gear 2010. A transmission shaft 2016 is rotatably mounted inside the first shaft hole 2011, and transmission bevel gears 2015 are fixedly mounted at both ends of the transmission shaft 2016. The transmission bevel gear 2015 and the first driven bevel gear 2010 are connected to each other. The first driven bevel gear 2010 at the rear is meshed with the first active bevel gear 2014 at one side away from the transmission bevel gear 2015, and an adjusting shaft 2013 is fixedly installed on the inner wall of the first active bevel gear 2014. A second shaft hole 2012 is opened on the back of the adjusting block 204, and the adjusting shaft 2013 is rotatably installed inside the second shaft hole 2012, and the adjusting shaft 2013 movably passes through the inside of a connecting shaft 205 at the rear, and a handle 2020 is fixedly installed on one end of the adjusting shaft 2013 away from the first active bevel gear 2014;

[0039] In this embodiment, the power component 4 drives the two connecting shafts 205 together with the two adjusting blocks 204 to rotate in opposite directions, and further drives the two pressing rollers 202 to rotate in opposite directions through the two rotating adjusting blocks 204 to crush the oil well cement material. It should be noted that in this device, the adjusting shaft 2013 can be driven to rotate synchronously by manually rotating the handle 2020, and the rotation of the adjusting shaft 2013 further drives the first active bevel gear 2014 to rotate together, and the rotation of the first active bevel gear 2014 drives the transmission bevel gear 2015 to rotate through the first driven bevel gear 2010, and further in the transmission shaft 2016 Under the action of the connection, the two transmission bevel gears 2015 rotate together, further driving another first driven bevel gear 2010 to rotate, thereby rotating the two internally threaded cylinders 207. The rotation of the two internally threaded cylinders 207 and the thread thrust generated by the two threaded columns 208 cause the internally threaded cylinders 207 to move along the axial direction of the threaded columns 208, causing the axis of the pressure roller 202 to be non-concentric with the axis of the connecting shaft 205, that is, the pressure roller 202 rotates eccentrically with the axial direction of the connecting shaft 205, thereby adjusting the minimum distance between the two pressure rollers 202 when rotating, which is convenient for crushing different particles of oil well cement materials.

[0040] Embodiment 2: The rolling component 2 also includes a telescopic groove 2017 provided on the outer wall of the pressure roller 202, a receiving plate 2018 is slidably installed inside the telescopic groove 2017, a side of the receiving plate 2018 located inside the telescopic groove 2017 is fixedly installed with a plurality of elastic sheets 2019 distributed front and back, and one end of the elastic sheet 2019 away from the telescopic groove 2017 is fixedly connected to the inner wall of the telescopic groove 2017 facing the receiving plate 2018;

[0041] Specifically, in this embodiment, the rotation of the pressure roller 202 also drives the receiving plate 2018 and the elastic sheet 2019 to rotate together through the telescopic groove 2017, and when the two pressure rollers 202 rotate eccentrically and approach each other, the adjacent surfaces of the two adjacent receiving plates 2018 on the left and right will first contact, and as the pressure roller 202 continues to rotate, the receiving plate 2018 slides toward the inside of the telescopic groove 2017 to compress the elastic sheet 2019, and when the two pressure rollers 202 rotate to the minimum spacing, the sliding distance of the receiving plate 2018 reaches the maximum, and the compression amount of the elastic sheet 2019 reaches the maximum. At this time, the ends of the two adjacent receiving plates 2018 on the left and right abut against each other, which can be used to press the dropped oil well cement material. The two rollers 202 are used to receive the dropped oil well cement materials, thereby preventing them from passing directly between the two pressure rollers 202, thereby ensuring the fineness of the rolling of the oil well cement materials. As the two pressure rollers 202 continue to rotate, the center of gravity moves away from each other from the closest position, and the left and right receiving plates 2018 that were previously in abutment gradually slide toward the periphery of the telescopic groove 2017 under the action of the rebound force of the elastic sheet 2019 until the end of the receiving plate 2018 contacts the inner wall of the rolling outer frame 201. As the pressure roller 202 rotates next, the oil well cement materials attached to the inner wall of the rolling outer frame 201 are scraped off, thereby achieving the dual functions of receiving the materials and cleaning the inner wall of the rolling outer frame 201.

[0042] Furthermore, a feeding port 2021 is provided through the top of the roller-pressed outer frame 201, and a discharging port 2022 is provided through the bottom of the roller-pressed outer frame 201, and the discharging port 2022 is located directly below the feeding port 2021. A material trough 2023 is fixedly installed at the bottom of the roller-pressed outer frame 201, and the material trough 2023 is located at the periphery of the bottom opening of the discharging port 2022, and the material trough 2023 penetrates a fixed end plate 1 located at the rear and extends to the periphery of its back side. The feeding port 2021 can facilitate the feeding component 3 to put oil well cement materials into the interior of the roller-pressed outer frame 201, so that they are rolled and crushed by two eccentrically rotating rollers 202, and discharged through the discharging port 2022 provided at the bottom of the roller-pressed outer frame 201, and then discharged into the external collection bag through the material trough 2023.

[0043] Embodiment 3: The feeding component 3 includes two feeding flaps 301 located between two fixed end plates 1, the two feeding flaps 301 are symmetrically distributed on the left and right, and the front and back sides of the two feeding flaps 301 are fixedly installed with hinge shafts 302, and the periphery of the hinge shafts 302 is installed with movable blocks 303 through bearings. Two left-right distributed positioning blocks 304 are fixedly installed on the side surfaces close to the two fixed end plates 1, and the positions of the positioning blocks 304 correspond to the positions of the movable blocks 303 one by one, and the interior of the positioning blocks 304 is provided with a slide groove 305, and the movable block 303 is slidably installed in the interior of the slide groove 305, and a rocker arm 306 is fixedly installed on the end of the hinge shaft 302 away from the feeding flap 301, and the two fixed end plates 1 are away from each other. Two sliding seats 307 distributed on the left and right are fixedly installed on one side of the sliding seat 307, and a slide bar 308 is slidably installed inside the sliding seat 307. The slide bar 308 movably runs through the top and bottom of the sliding seat 307, and the slide bar 308 is located at the bottom of the rocker arm 306. A connecting rod 309 is hinged between the top of the slide bar 308 and the end of the rocker arm 306 away from the hinge shaft 302. The sliding seat 307 is located at the top of the connecting shaft 205, and a guide wheel 3010 is rotatably installed at the lower front part of the slide bar 308. A first cam 3011 is fixedly installed on the outer wall of the connecting shaft 205, and the outer wall of the first cam 3011 abuts against the outer wall of the guide wheel 3010. The guide plate 5 is located at the top of the feeding flap 301, and the two guide plates 5 are arranged in a funnel shape;

[0044] The left and right sides of the movable block 303 are fixedly installed with an oscillation spring 3012, and one end of the oscillation spring 3012 away from the movable block 303 is fixedly connected to the side wall of the slide slot 305, and the outer wall of the hinge shaft 302 is fixedly installed with a wave cam 3013, and a positioning plate 3014 is fixedly installed on one side of the positioning block 304 close to the wave cam 3013, and the positioning plate 3014 is located at one end of the positioning block 304, the positioning plate 3014 is located on one side of the wave cam 3013, and a positioning pin 3015 is rotatably installed on one side of the positioning plate 3014 away from the positioning block 304, and the positioning pin 3015 is located at one end of the positioning plate 3014 close to the wave cam 3013, and the outer wall of the positioning pin 3015 abuts against the outer wall of the wave cam 3013;

[0045] Specifically, the first cam 3011 is driven to rotate together through the connecting shaft 205, and the first cam 3011 pushes the guide wheel 3010 and the slide bar 308 to move back and forth up and down along the inside of the sliding seat 307, and further drives the rocking arm 306 to rotate up and down under the connection action of the connecting rod 309. The rocking arm 306 rotates up and down and drives the feeding flap 301 to rotate up and down through the hinge shaft 302. It should be noted that the installation angle of the first cam 3011 and the connecting shaft 205 of the device is adaptively set, so that when the two pressure rollers 202 rotate eccentrically, when the center of gravity position of the pressure roller 202 rotates from the top position to approach each other, that is, when the two pressure rollers 202 rotate eccentrically and gradually approach each other, the first cam 3011 just pushes the guide wheel 3010 and the slide bar 308, causing the left and right feeding flaps 301 to flip downward around the connection position between the hinge shaft 302 and the movable block 303, so that the oil well cement material is dropped downward, and the dropped oil well cement material is passed through The movable block 303 is moved along the inner wall of the chute 305 by the movement of the hinge shaft 302, so that the two oscillation springs 3012 on the left and right of the movable block 303 generate a rebound force. Further, with the continued rotation of the wave cam 3013 and the rebound force of the oscillation spring 3012, the movable block 303 is swung left and right along the inside of the chute 305 to generate an oscillation effect, and the feeding flap 301 is driven to oscillate together through the hinge shaft 302. Under the oscillation effect, the oil well cement material on the feeding flap 301 can be placed more thoroughly and cleanly.

[0046] Furthermore, a torsion spring 3016 is provided on the outer periphery of the hinge shaft 302, and the torsion spring 3016 is fixedly installed between the feeding flap 301 and the movable block 303. When the hinge shaft 302 drives the feeding flap 301 to flip downward, the torsion spring 3016 is twisted to generate a rebound force. Therefore, when the two pressure rollers 202 rotate eccentrically to move away from each other, the first cam 3011 just ends the upward push on the guide wheel 3010, the slide bar 308 slides downward, and ends the upward push on the rocker arm 306 through the connecting rod 309, and the rebound force of the torsion spring 3016 will push the hinge shaft 302 and the feeding flap 301 to rotate. After the two feeding flaps 301 rotate, the adjacent surfaces contact each other, thereby interrupting the feeding. Therefore, when the two pressure rollers 202 rotate eccentrically to move away from each other, no oil well cement material will pass through, thereby avoiding the problem of insufficient crushing of the oil well cement material.

The number of the secondary driven bevel gears 404 is two, and the two secondary driven bevel gears 404 are respectively fixedly mounted on the outer walls of the left and right connecting shafts 205.

[0048] Specifically, the output shaft of the power motor 409 drives the primary active bevel gear 406 to rotate through the driving shaft 407, and the driving shaft 407 can rotate more stably through the limiting effect of the shaft frame 408. The primary active bevel gear 406 rotates and then drives the transfer shaft 402 to rotate around the left and right adapters 401 through the meshing effect with the primary driven bevel gear 405. The rotation of the transfer shaft 402 further drives the secondary active bevel gears 403 at both ends to rotate together. The two secondary active bevel gears 403 rotate through the two secondary driven bevel gears 404 to drive the two connecting shafts 205 together with the two adjusting blocks 204 to rotate in opposite directions, thereby realizing the operation of the rolling component 2.

[0049] When the oil well cement roller press of the present scheme is working, the oil well cement material is put into the top of the two guide plates 5 through the material conveyor. Because the two guide plates 5 are arranged in a funnel shape, the put oil well cement material flows along the top of the two guide plates 5 to the middle, and is put into the top of the two feeding flaps 301 from the middle of the two guide plates 5. At the same time, the output shaft of the power motor 409 drives the primary active bevel gear 406 to rotate through the driving shaft 407, and the driving shaft 407 can rotate more stably through the limiting effect of the shaft frame 408. The primary active bevel gear 406 rotates and then drives the transfer shaft 402 to rotate around the left and right adapter seats 401 through the meshing action with the primary driven bevel gear 405. The rotation of the transfer shaft 402 further drives the secondary active bevel gears 403 at both ends to rotate together. The two secondary active bevel gears 403 rotate through the two secondary driven bevel gears 404 to drive the two connecting shafts 205 together with the two adjusting blocks 204 to rotate in the opposite direction, and further through the two rotating adjusting blocks 20 4 drives the two pressing rollers 202 to rotate in opposite directions. It should be noted that in this device, the adjusting shaft 2013 can be driven to rotate synchronously by manually rotating the handle 2020. The rotation of the adjusting shaft 2013 further drives the first active bevel gear 2014 to rotate together. The rotation of the first active bevel gear 2014 drives the transmission bevel gear 2015 to rotate through the first driven bevel gear 2010. Further, under the connection of the transmission shaft 2016, the two transmission bevel gears 2015 rotate together, further driving another first driven bevel gear 2010 to rotate, thereby rotating the two internally threaded cylinders 207. The rotation of the two internally threaded cylinders 207 and the thread thrust generated by the two threaded columns 208 cause the internally threaded cylinders 207 to move along the axial direction of the threaded columns 208, causing the axis of the pressing roller 202 to be non-concentric with the axis of the connecting shaft 205, that is, the pressing roller 202 rotates eccentrically with the axial direction of the connecting shaft 205, thereby adjusting the minimum distance between the two pressing rollers 202 when rotating, which is convenient for crushing different particles of oil well cement.

[0050] At the same time, the connecting shaft 205 also drives the first cam 3011 to rotate together, and the first cam 3011 pushes the guide wheel 3010 and the slide bar 308 to move back and forth up and down along the inside of the sliding seat 307, and further drives the rocker arm 306 to rotate up and down under the connection action of the connecting rod 309. The rocker arm 306 rotates up and down and drives the feeding flap 301 to rotate up and down through the hinge shaft 302. It should be noted that the installation angle of the first cam 3011 and the connecting shaft 205 of the device is adaptively set, so that when the two pressure rollers 202 rotate eccentrically, when the center of gravity position of the pressure roller 202 rotates from the top position to approach each other, that is, when the two pressure rollers 202 rotate eccentrically and gradually approach each other, the first cam 3011 just pushes the guide wheel 3010 and the slide bar 308, causing the two left and right feeding flaps 301 to flip downward around the connection position between the hinge shaft 302 and the movable block 303, and the oil well cement material is dropped downward. The feeding port 2021 falls between the two eccentrically rotating and mutually approaching rollers 202, thereby rolling and crushing the oil well cement material. During the period when the articulated shaft 302 drives the feeding flap 301 to flip downward, it also drives the wave cam 3013 to rotate together. The rotation of the wave cam 3013 and the positioning pin 3015 generate a cam thrust, causing the articulated shaft 302 and the wave cam 3013 to move away from the positioning pin 3015. The movement of the articulated shaft 302 drives the movable block 303 to slide along the inner wall of the slide groove 305, so that the two oscillation springs 3012 on the left and right of the movable block 303 generate a rebound force. Further, under the continued rotation of the wave cam 3013 and the rebound force of the oscillation spring 3012, the movable block 303 swings left and right along the inside of the slide groove 305 to generate an oscillation effect, and drives the feeding flap 301 to oscillate together through the articulated shaft 302. Under the oscillation effect, the oil well cement material on the feeding flap 301 can be placed more thoroughly and cleanly.

[0051] The rotation of the pressure roller 202 also drives the receiving plate 2018 and the elastic sheet 2019 to rotate together through the telescopic groove 2017, and when the two pressure rollers 202 rotate eccentrically and approach each other, the adjacent surfaces of the two adjacent receiving plates 2018 on the left and right will first contact, and as the pressure roller 202 continues to rotate, the receiving plate 2018 slides toward the inside of the telescopic groove 2017, compressing the elastic sheet 2019, and when the two pressure rollers 202 rotate to the minimum spacing, the sliding distance of the receiving plate 2018 reaches the maximum, and the compression amount of the elastic sheet 2019 reaches the maximum. At this time, the ends of the two adjacent receiving plates 2018 on the left and right abut against each other, so that the dropped oil well cement material can be received. , preventing the dropped oil well cement material from passing directly between the two pressing rollers 202, ensuring the fineness of the rolling of the oil well cement material, and as the two pressing rollers 202 continue to rotate, the center of gravity moves away from each other from the closest position, and the left and right receiving plates 2018 that were previously in abutment state gradually slide toward the periphery of the telescopic groove 2017 under the action of the rebound force of the elastic sheet 2019, until the end of the receiving plate 2018 contacts the inner wall of the rolling outer frame 201, and as the pressing roller 202 rotates in the following process, the oil well cement material attached to the inner wall of the rolling outer frame 201 is scraped off, achieving the dual functions of receiving the material and cleaning the inner wall of the rolling outer frame 201;

[0052] When the two pressure rollers 202 rotate eccentrically away from each other, the first cam 3011 just ends the upward pushing action on the guide wheel 3010, the slide bar 308 slides downward, and ends the upward pushing action on the rocker arm 306 through the connecting rod 309, and the resilience of the torsion spring 3016 pushes the hinge shaft 302 and the feeding flap 301 to rotate. After the two feeding flaps 301 rotate, the adjacent surfaces contact each other, thereby interrupting the feeding. Therefore, when the two pressure rollers 202 rotate eccentrically away from each other, no oil well cement material will pass through, thereby avoiding the problem of insufficient crushing of the oil well cement material.

[0053] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention.
