Description

Technical Field

[0001] This invention belongs to the field of general equipment manufacturing technology, specifically an automatic sand conveying machine for oil drilling. Background Technology

[0002] Drilling fluid carrying rock cuttings passes through a mud and sand vibrating screen, where solid-liquid separation is achieved through vibration. The sand falls into a receiving funnel, and the sand in the receiving funnel enters a sand conveying device through a discharge pipe. It is then transported to a designated location by a conveyor belt.

[0003] Rock chips processed by the vibrating screen are still wet. The vibrating screen can only achieve primary solid-liquid separation. The processed rock chips contain water. After these wet solid materials are conveyed out of the automatic sand conveyor, some sand tends to stick to the conveyor belt, resulting in some sand remaining on the conveyor belt, which makes it inconvenient to clean the conveyor belt. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention is: an automatic sand conveying machine for oil drilling, including support legs, and further comprising: The transmission mechanism is set above the support leg, the conveyor belt is sleeved on the transmission mechanism, the unloading mechanism is set at one end of the transmission mechanism, and the cleaning mechanism is installed at the other end of the transmission mechanism. The cleaning mechanism includes a first scraper disposed inside the transmission mechanism, the end of which contacts the surface of the transmission belt to perform preliminary cleaning of residual sand and gravel; an air removal component disposed below the first scraper; and a scraping component installed at one end of the transmission mechanism.

[0005] Furthermore, the cleaning mechanism also includes: A driver, which is symmetrically arranged at one end of the transmission mechanism; The first baffle is rotatably connected to the driver, and the top of the first baffle is connected to the bottom of the air removal assembly. The first baffle is used to adjust the angle of the air removal assembly. A support rod, which is installed above the first baffle; The second baffle is installed above the support rod, and its top is connected to the bottom of the first scraper. The second baffle is used to adjust the angle of the first scraper.

[0006] Furthermore, the transmission mechanism includes: The frame has an adjustment rod at its bottom, and the surface of the adjustment rod is evenly provided with movable grooves. A connecting rod is provided, which passes through a movable groove, and its two ends are connected to the support leg.

[0007] Furthermore, the transmission mechanism also includes: A transmission shaft is evenly arranged inside the frame, and the conveyor belt is sleeved on the transmission shaft; The bumps are located at both ends of the transmission shaft. The bumps and the transmission shaft cause the conveyor belt to be in a state where the two ends are raised and the middle is low, so that the sand and gravel can be reduced from spilling.

[0008] Furthermore, the feeding mechanism includes: A feeding hopper is installed above the machine frame; Inclined plates, which are symmetrically arranged inside the hopper; A water filtration assembly is installed inside the feed hopper; Water guide pipes are symmetrically arranged outside the feed hopper, and the positions of the water guide pipes correspond to the positions of the green water components. A rotating plate is rotatably connected inside the hopper and is positioned on the corresponding surface of the conveyor belt, allowing sand and gravel to move along the plate and preventing them from spilling from the beginning of the conveyor belt.

[0009] Furthermore, the water filtration assembly includes: The guide plate is symmetrically arranged inside the hopper. The two ends of the guide plate are rotatably connected to the outside of the inclined plate. The surface of the guide plate is provided with a water guide groove. The water on the sand and gravel is guided by the inclined guide plate and can be deposited at both ends of the guide plate and flow out through the water guide groove. Holes corresponding to the positions of the water guide grooves are opened on the hopper. The opening and closing rods are evenly arranged inside the hopper. The two ends of the opening and closing rods pass through the inclined plates and are rotatably connected to the inside of the hopper. The two ends of the opening and closing rods are connected to the bottom of the guide plates. The opening and closing rods drive the upper part of the guide plates to remain stationary while the lower part moves closer to each other, so that the sand and gravel fall from the gap between the two guide plates and the hopper onto the conveyor belt.

[0010] Furthermore, the water filtration assembly also includes: The filter plates are symmetrically arranged inside the hopper and their positions correspond to the water guide channel. The filter plates can prevent sand and gravel from flowing out with the water. An elastic sheet is mounted above the guide plate; The first slider is installed on the outside of the filter plate and is slidably connected to the outside of the hopper.

[0011] Furthermore, the air removal assembly includes: The second scraper has two ends that are rotatably connected to the inside of the frame, and the surface of the second scraper has an opening. The ends of both the first scraper and the second scraper are rotatably connected to the inside of the frame. An extrusion bar, disposed inside the opening, is made of an elastic material such as a spring, and supports the rubber scraper to keep it in contact with the surface of the conveyor belt; A rubber scraper, wherein the rubber scraper is disposed at the other end of the extrusion rod; A high-pressure nozzle is installed inside the second scraper.

[0012] Further, the scraping assembly includes: An arc-shaped rod is installed inside the frame, and the arc of the rod is similar to the surface arc of the conveyor belt. The second slider is slidably connected to the outside of the frame; The connector is mounted above the second slider and is an elastic connection, allowing the moving ring to reciprocate on the arc-shaped rod.

[0013] Furthermore, the scraping assembly also includes: A movable ring, which is sleeved on the outside of the arc-shaped rod, and the outside of the movable ring is connected to the connector; The scraper blades are evenly distributed on the outside of the moving ring and are sleeved on the outside of the moving ring. The scraper blades are made of rubber and are elastic, which can compensate for the deformation of the conveyor belt. The scraper blades maintain contact with the conveyor belt and scrape and clean it back and forth.

[0014] The beneficial effects of this invention are as follows: 1. This invention, through the setting of a cleaning mechanism, firstly scrapes the conveyor belt to initially clean it, removing and transferring most of the sand and gravel. Subsequently, the air removal component blows air onto the surface of the conveyor belt using high-pressure airflow, thereby removing the remaining sand and gravel from the conveyor belt and drying the conveyor belt, further reducing the amount of sand and gravel adhering to the conveyor belt. The scraping component continues to scrape the conveyor belt from the bottom. Through multiple cleaning processes, the conveyor belt is kept clean, reducing sand and gravel adhesion and preventing sand and gravel from entering between the conveyor belt and the transmission shaft, thereby increasing the friction between the conveyor belt and the transmission shaft and causing severe wear on the conveyor belt. Reducing sand and gravel adhesion also reduces sand and gravel loss.

[0015] 2. This invention, by setting up a water filtration assembly, has an opening and closing rod that drives both ends of the guide plate to be in an open state, contacting the inner wall of the hopper. This intercepts the sand and gravel above the guide plate, and airflow draws out the moisture inside the sand and gravel, causing the moisture to flow out along the water guide channel. During this process, the water filtration plate blocks the holes in the hopper to prevent the sand and gravel from flowing out of the holes. After the sand and gravel in the batch are drained of moisture, the opening and closing rod drives the bottom of the guide plate to close, causing the sand and gravel to fall from the surface of the guide plate onto the conveyor belt. Airflow then carries the moisture contained in the sand and gravel out along the guide plate, further reducing the moisture content of the sand and gravel, and also reducing its adhesion to the conveyor belt.

[0016] 3. This invention, by setting up an air removal component, brings the conveyor belt into contact with the second scraper, allowing the rubber scraper on the extrusion rod to further scrape the conveyor belt. Since the surface of the conveyor belt is not flat but has a concave arc surface, the rubber scraper, driven by the extrusion rod, can adjust according to the current state of the conveyor belt, keeping it in contact with the surface and further cleaning surfaces that the first scraper cannot reach. At the same time, the high-pressure nozzle connected to an external air blower can blow air onto the surface of the conveyor belt, causing the blown-down sand and gravel to fall from the opening of the second scraper. The first scraper blocks the blown-down sand and gravel, preventing it from flying upwards and affecting the construction site environment.

[0017] 4. By setting up a scraping component, the present invention reduces the amount of sand and gravel residue on the conveyor belt surface after two cleaning cycles. At this point, the second slider drives the moving ring to move back and forth along the arc-shaped rod, causing the scraper on the moving ring to contact the conveyor belt surface and perform scraping cleaning. When wet sand and gravel adhere to the conveyor belt surface, it is difficult to completely scrape them off in one go. However, after the air removal component dries the conveyor belt surface, the small amount of sand and gravel remaining on the conveyor belt surface can be more easily cleaned. The sand and gravel can be removed by the contact between the scraper and the conveyor belt. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] Example 1, please refer to Figures 1-5 The present invention provides a technical solution: an automatic sand conveying machine for oil drilling, which is described as follows.

[0022] Including support leg 1, it also includes: The transmission mechanism 2 is set above the support leg 1, the conveyor belt 3 is sleeved on the transmission mechanism 2, the unloading mechanism 4 is set at one end of the transmission mechanism 2, and the cleaning mechanism 5 is installed at the other end of the transmission mechanism 2. Transmission mechanism 2 includes: The frame 201 has an adjusting rod 202 at its bottom, and the surface of the adjusting rod 202 is evenly provided with movable grooves 203. The connecting rod 204 passes through the movable groove 203 and its two ends are connected to the support leg 1.

[0023] Transmission mechanism 2 also includes: Transmission shaft 205 is evenly arranged inside frame 201, and conveyor belt 3 is sleeved on transmission shaft 205; The protrusions 206 are located at both ends of the transmission shaft 205. The protrusions 206 and the transmission shaft 205 cause the conveyor belt 3 to be in a state where the two ends are raised and the middle is low, so that the sand and gravel can be reduced from spilling.

[0024] During use, the angle of the frame 201 can be adjusted according to the site environment, the support leg 1 can be adjusted to different heights, the connecting rod 204 moves in the movable groove 203 to adjust the overall angle of the frame 201, and then the support leg 1 is fixed on the adjusting rod 202 to realize the angle change of the frame 201.

[0025] During operation, the sand and gravel dewatered by the vibrating screen are injected into the feeding mechanism 4. After the feeding mechanism 4 further absorbs a certain amount of water, the conveying mechanism 2 conveys the sand and gravel. After the conveying is completed, the cleaning mechanism 5 cleans the residual sand and gravel on the conveyor belt 3.

[0026] The cleaning mechanism 5 includes a first scraper 501 disposed inside the transmission mechanism 2, the end of the first scraper 501 being in contact with the surface of the transmission belt to perform preliminary cleaning of residual sand and gravel, an air removal component 506 disposed below the first scraper 501, and a scraping component 507 installed at one end of the transmission mechanism 2.

[0027] Cleaning agency 5 also includes: Driver 502 is symmetrically arranged at one end of transmission mechanism 2; The first baffle 503 is rotatably connected to the driver 502. The top of the first baffle 503 is connected to the bottom of the air removal assembly 506. The first baffle 503 is used to adjust the angle of the air removal assembly 506. Support rod 504 is installed above the first baffle 503; The second baffle 505 is installed above the support rod 504. The top of the second baffle 505 is connected to the bottom of the first scraper 501. The second baffle 505 is used to adjust the angle of the first scraper 501.

[0028] After the sand and gravel are removed from the conveyor belt 3, residual sand and gravel still adhere to the surface of the conveyor belt 3. At this time, the first scraper 501 performs preliminary cleaning of the conveyor belt 3, scraping off and transferring most of the sand and gravel. Subsequently, the air removal component 506 blows air onto the surface of the conveyor belt 3 through high-pressure airflow, so that the remaining sand and gravel on the surface of the conveyor belt 3 can be removed from the conveyor belt 3 and the conveyor belt 3 is dried, further reducing the amount of sand and gravel adhering to the conveyor belt 3. The scraping component 507 continues to scrape the conveyor belt 3 from the bottom. Through multiple cleaning, the conveyor belt 3 is kept clean, reducing the adhesion of sand and gravel and preventing sand and gravel from entering between the conveyor belt 3 and the transmission shaft 205, thereby increasing the friction between the conveyor belt 3 and the transmission shaft 205, causing serious wear on the conveyor belt 3, reducing the adhesion of sand and gravel, and also reducing the loss of sand and gravel.

[0029] The feeding mechanism 4 includes: The feeding hopper 401 is installed above the frame 201; Inclined plate 402 is symmetrically arranged inside the feed hopper 401; Water filtration assembly 404 is installed inside the feed hopper 401; Water guide pipe 403 is symmetrically arranged outside the feed hopper 401. The position of water guide pipe 403 corresponds to the position of green water component. Water guide pipe 403 is connected to a water pumping device. By increasing the airflow between sand and gravel, water can flow out faster. The rotating plate 405 is rotatably connected to the inside of the hopper 401. The rotating plate 405 is set on the corresponding surface of the conveyor belt 3 so that the sand and gravel can move along the rotating plate 405 and avoid spilling from the beginning of the conveyor belt 3.

[0030] Initially, the water filter assembly 404 remains open, allowing the sand and gravel to absorb moisture before falling onto the conveyor belt 3 from both sides of the water filter assembly 404. The rotating plate 405 and the inclined plate 402 are placed at an angle to adjust the bottom space of the hopper 401. The tilt angle of the rotating plate 405 and the inclined plate 402 is adjusted according to the width of the conveyor belt 3 to ensure that the sand and gravel are located in the middle of the conveyor belt 3 during feeding, avoiding spillage from the beginning and reducing the moisture in the sand and gravel, further reducing the adhesion of sand and gravel on the conveyor belt 3. The water guide pipe 403 is connected to an external water pumping device, which increases the airflow between the sand and gravel to make the moisture flow out faster.

[0031] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: based on embodiment 1, the water filtration assembly 404 includes: Guide plates 4042 are symmetrically arranged inside the hopper 401. The two ends of the guide plates 4042 are rotatably connected to the outside of the inclined plate 402. Water guide grooves 4043 are opened on the surface of the guide plates 4042. Water on the sand and gravel is guided by the inclined guide plates 4042 and can be deposited at both ends of the guide plates 4042 and flow out through the water guide grooves 4043. Holes corresponding to the positions of the water guide grooves 4043 are opened on the hopper. The opening and closing rods 4041 are evenly arranged inside the hopper 401. The two ends of the opening and closing rods 4041 pass through the inclined plate 402 and are rotatably connected to the inside of the hopper 401. The two ends of the opening and closing rods 4041 are connected to the bottom of the guide plate 4042. The opening and closing rods 4041 drive the guide plate 4042 to move closer together from the bottom while the top remains stationary, so that the sand and gravel fall from the gap between the guide plates 4042 and the hopper 401 onto the conveyor belt 3.

[0032] The water filtration assembly 404 also includes: The filter plate 4044 is symmetrically arranged inside the feed hopper 401. The position of the filter plate 4044 corresponds to that of the water guide channel 4043. The filter plate 4044 can prevent sand and gravel from flowing out with the water. Elastic sheet 4045 is installed above guide plate 4042, and elastic sheet 4045 keeps the upper parts of the two guide plates 4042 connected. The first slider 4046 is installed on the outside of the filter plate 4044 and is slidably connected to the outside of the hopper 401.

[0033] Initially, the opening and closing rod 4041 drives the two ends of the guide plate 4042 to be in an open state, contacting the inner wall of the hopper 401, intercepting the sand and gravel above the guide plate 4042. The airflow draws out the moisture inside the sand and gravel, allowing the moisture to flow out along the water guide groove 4043. During this process, the filter plate 4044 blocks the hole in the hopper 401 to prevent the sand and gravel from flowing out of the hole. After the moisture is drawn out from the batch of sand and gravel put into the hopper 401, the opening and closing rod 4041 drives the bottom of the guide plate 4042 to close, allowing the sand and gravel to fall from the surface of the guide plate 4042 onto the conveyor belt 3. The airflow carries the moisture contained in the sand and gravel out along the guide plate 4042, further reducing the moisture content of the sand and gravel, and also reducing its adhesion to the conveyor belt 3.

[0034] The air evacuation assembly 506 includes: The second scraper 5061 has two ends that are rotatably connected to the inside of the frame 201. The surface of the second scraper 5061 has an opening 5062. The ends of both the first scraper 501 and the second scraper 5061 are rotatably connected to the inside of the frame 201. The extrusion bar 5063 is disposed inside the opening 5062. The extrusion bar 5063 is made of an elastic material such as a spring and supports the rubber scraper 5064 so that it remains in contact with the surface of the conveyor belt 3. Rubber scraper 5064 is disposed at the other end of extrusion rod 5063; High-pressure nozzle 5065 is installed inside the second scraper 5061.

[0035] After the residual sand and gravel on the conveyor belt 3 is initially cleaned by the first scraper 501, the conveyor belt 3 continues to move and comes into contact with the second scraper 5061. This causes the rubber scraper 5064 on the extrusion rod 5063 to further scrape the conveyor belt 3. Since the surface of the conveyor belt 3 is not flat but has a concave arc surface, the rubber scraper 5064 can be adjusted according to the current state of the conveyor belt 3 under the action of the extrusion rod 5063, so that the rubber scraper 5064 keeps in contact with the surface of the conveyor belt 3, and the surface that the first scraper 501 cannot clean is further cleaned. At the same time, the high-pressure nozzle 5065 is connected to an external air blower to blow air onto the surface of the conveyor belt 3, causing the blown-down sand and gravel to fall from the opening 5062 of the second scraper 5061. The first scraper 501 blocks the blown-down sand and gravel, preventing the sand and gravel from flying up from the bottom and affecting the construction site environment.

[0036] Scraping component 507 includes: Arc rod 5075 is installed inside the frame 201, and the arc of arc rod 5075 is similar to the surface arc of conveyor belt 3; The second slider 5071 is slidably connected to the outside of the frame 201; Connector 5072 is installed above the second slider 5071. Connector 5072 is an elastic connection, which allows the moving ring 5073 to reciprocate on the arc rod 5075.

[0037] The scraping assembly 507 also includes: The movable ring 5073 is sleeved on the outside of the arc-shaped rod 5075, and the outside of the movable ring 5073 is connected to the connector 5072. Scraper 5074 is evenly distributed on the outside of the moving ring 5073. The scraper 5074 is sleeved on the outside of the moving ring 5073. The scraper 5074 is made of rubber and has elasticity. It can compensate for the deformation of the conveyor belt 3. The scraper 5074 keeps in contact with it and scrapes and cleans it back and forth.

[0038] After two cleaning cycles, there is less sand and gravel residue on the surface of conveyor belt 3. At this time, the second slider 5071 drives the moving ring 5073 to move back and forth along the arc rod 5075, so that the scraper 5074 on the moving ring 5073 contacts the surface of conveyor belt 3 and performs scraping cleaning. When wet sand and gravel adhere to the surface of conveyor belt 3, it is difficult to completely remove them in one go. However, after the air removal component 506 dries the surface of conveyor belt 3, the small amount of sand and gravel remaining on the surface of conveyor belt 3 can be more easily cleaned. The sand and gravel can be removed by the contact between the scraper 5074 and the conveyor belt 3.

[0039] The specific workflow is as follows: During use, the angle of the frame 201 can be adjusted according to the site environment, the support leg 1 can be adjusted to different heights, the connecting rod 204 moves in the movable groove 203 to adjust the overall angle of the frame 201, and then the support leg 1 is fixed on the adjusting rod 202 to realize the angle change of the frame 201.

[0040] During operation, the sand and gravel dewatered by the vibrating screen are injected into the feeding mechanism 4. The water filter component 404 is kept open so that the sand and gravel absorb water through the water filter component 404 and then fall onto the conveyor belt 3 from both sides of the water filter component 404. The rotating plate 405 and the inclined plate 402 are placed at an angle to adjust the bottom space of the feeding hopper 401. The tilt angle of the rotating plate 405 and the inclined plate 402 is adjusted according to the width of the conveyor belt 3 to ensure that the sand and gravel are located in the middle of the conveyor belt 3 during feeding, avoiding spillage from the beginning and reducing the moisture in the sand and gravel, further reducing the adhesion of sand and gravel on the conveyor belt 3. The water pipe 403 is connected to an external water pumping device to increase the airflow between the sand and gravel, so that the water flows out faster. After the sand and gravel are removed from the conveyor belt 3, residual sand and gravel still adhere to the surface of the conveyor belt 3. At this time, the first scraper 501 performs preliminary cleaning of the conveyor belt 3, scraping away and transferring most of the sand and gravel. Subsequently, the air removal component 506 blows air onto the surface of the conveyor belt 3 through high-pressure airflow, so that the remaining sand and gravel on the surface of the conveyor belt 3 can be removed from the conveyor belt 3 and the conveyor belt 3 is dried, further reducing the amount of sand and gravel adhering to the conveyor belt 3. The scraping component 507 continues to scrape the conveyor belt 3 from the bottom. Through multiple cleaning processes, the conveyor belt 3 is kept clean, and the adhesion of sand and gravel is reduced.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
