Description

Technical Field

[0001] This invention relates to the field of concrete technology, and more specifically, to a concrete aggregate conveying and pre-wetting device. Background Technology

[0002] Concrete aggregate pre-wetting devices are commonly used to pre-wet concrete. Their main function is to pre-wet the aggregates during concrete production to improve the uniformity and quality stability of the concrete. Therefore, the use of pre-wetting devices is a crucial step in concrete production. A search revealed that utility model patent CN210589933U discloses a concrete aggregate conveying pre-wetting system. The key technical features include a frame with a first conveyor belt mounted on it. A first spraying device is positioned above the first conveyor belt and connected to a first water supply device. A first driving component is mounted on the frame to drive the first conveyor belt to rotate. The first conveyor belt has a loading end and a unloading end. A second conveyor belt is positioned at the unloading end of the first conveyor belt. A second spraying device is positioned above the second conveyor belt and connected to a second water supply device. A temporary storage box is positioned between the first and second conveyor belts, containing a mixing device. A discharge port is located on the side of the temporary storage box near the second conveyor belt, with a discharge plate at the discharge port. An opening / closing driving component is positioned between the discharge plate and the temporary storage box, driving the discharge plate to open or close the discharge port, thereby improving the uniformity of pre-wetting. However, in the existing technology, the device lacks a splash-proof mechanism, allowing water to easily splash onto the ground, making the device inconvenient to use. Furthermore, when the device is in use, there is no recycling mechanism, making it difficult to collect and reuse the wastewater. Therefore, improvements are needed. Summary of the Invention

[0003] In view of the problems existing in the prior art, the purpose of the present invention is to provide a concrete aggregate conveying pre-wetting device that can prevent water from splashing onto the ground and allow wastewater on the device to be reused.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] A concrete aggregate conveying and pre-wetting device includes a conveyor belt, a support column fixedly connected to the lower end of the conveyor belt, a fixed column fixedly connected to the upper end of the conveyor belt, a top plate fixedly connected to the upper end of the fixed column, a water tank fixedly installed on the upper end of the top plate, a water inlet provided inside the water tank, a connecting cover threadedly connected inside the water inlet, a first water pump fixedly installed inside the top plate and in contact with the water tank, a water collection shell fixedly connected to the lower end of the top plate and in contact with the first water pump, a nozzle fixedly connected inside the water collection shell, a splash-proof mechanism provided on the conveyor belt, and a recycling mechanism provided on the support column.

[0006] In a preferred embodiment of the present invention, the splash-proof mechanism includes a mounting rod, with the outer side of the support column contacting the mounting rod. A mounting block is fixedly connected to the outer side of the mounting rod, and the mounting block contacts the support column. A bolt is threadedly connected to the inside of the support column, and the bolt contacts the mounting block.

A baffle is fixedly connected to the upper end of the cylinder rod, and a sliding rod is fixedly connected to the outer side of the baffle. The sliding rod is slidably connected to the conveyor belt, and a guide block is slidably connected inside the sliding rod. The guide block is fixedly connected to the conveyor belt, and the baffle is slidably connected to the conveyor belt. By opening the cover and pouring lubricating oil into the sliding rod through the oil inlet, the guide block and guide rod are lubricated. Then, the cylinder is activated, driving the baffle and other components upward to a designated position, thereby preventing water from splashing onto the ground and making the device easy to use.

[0007] As a preferred embodiment of the present invention, the sliding rod is provided with a telescopic sleeve inside, and the telescopic sleeve is provided with a guide block inside. By designing the telescopic sleeve, the interior of the sliding rod can be sealed.

Then the cylinder is started, and the cylinder drives the baffle and other components to move upward to the designated position, so that the baffle can prevent water from splashing onto the ground, making the device easy to use.

[0015] (2) In this invention, by designing components such as a collection shell, a filter screen, a motor, a screw, a bearing, and a threaded block, the collection shell can collect wastewater on the conveyor belt, the filter screen can filter the wastewater, and then the second water pump is started to pump the water in the collection shell into the water tank, thereby recycling the wastewater and reusing the wastewater on the device. The motor is started, and the motor drives the screw and the threaded block to move in a threaded motion. The movement of the threaded block drives the impact block and the rubber pad to move. The movement of the rubber pad impacts the elastic block and vibrates. The vibration of the elastic block drives the filter screen to vibrate, thereby allowing the water to be filtered quickly from the filter screen and improving the working efficiency of the filter screen.

[0030] In this embodiment, by opening the cover 1112, lubricating oil is poured into the sliding rod 117 through the oil inlet 1111, thereby lubricating the guide block 118 and guide rod 1110 and other components. Then, the cylinder 114 is activated, and the cylinder 114 drives the baffle 116 and other components to move upward to the designated position, thereby preventing water from splashing onto the ground and making the device easy to use.

[0031] For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The sliding rod 117 is provided with a telescopic sleeve 119 inside, and the telescopic sleeve 119 is provided with a guide block 118 inside.

[0032] In this embodiment, the interior of the sliding rod 117 can be sealed by designing a telescopic sleeve 119.

[0033] For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The guide block 118 has a guide rod 1110 slidably connected inside, and the two ends of the guide rod 1110 are fixedly connected to the sliding rod 117.

[0034] In this embodiment, the guide rod 1110 is designed to connect to the guide block 118.

[0035] For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The sliding rod 117 has an oil inlet 1111 inside, and the oil inlet 1111 is connected to a cover 1112 by a thread.

[0036] In this embodiment, the oil filling port 1111 can be sealed by designing a cover 1112.

[0037] For details, please refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 The recycling mechanism 12 includes a collection shell 121. The collection shell 121 is fixedly installed on the outside of the support column 2. A filter screen 122 is fixedly connected inside the collection shell 121. A motor 123 is fixedly installed on the outside of the collection shell 121. The rotating shaft of the motor 123 is rotatably connected to the collection shell 121. A screw 124 is fixedly connected to the right end of the rotating shaft of the motor 123. The screw 124 is rotatably connected to the collection shell 121. A threaded block 126 is threadedly connected to the outside of the screw 124. A moving block 127 is fixedly connected to the lower end of the threaded block 126. A wear-resistant sleeve 128 is fixedly connected inside the moving block 127. A guide rod 129 is slidably connected inside the sleeve 128. Both ends of the guide rod 129 are fixedly connected to the collection shell 121. A groove 1210 is opened inside the wear-resistant sleeve 128. An impact block 1212 is fixedly connected to the upper end of the threaded block 126. A rubber pad 1213 is fixedly connected to the outer side of the impact block 1212. An elastic block 1214 is fixedly connected to the lower end of the filter screen 122. A water outlet pipe 1215 is fixedly connected inside the collection shell 121. A connecting pipe 1216 is fixedly connected inside the water outlet pipe 1215. A second water pump 1217 is installed on the connecting pipe 1216. A second water pump 1217 is installed on the outer side of the water tank 5.

[0038] In this embodiment, wastewater on the conveyor belt 1 can be collected by the collection shell 121, and the wastewater can be filtered by the filter screen 122. Then, the second water pump 1217 is started to pump the water in the collection shell 121 into the water tank 5, thereby recycling the wastewater and reusing the wastewater on the device. The motor 123 is started, and the motor 123 drives the screw 124 and the threaded block 126 to move in a threaded motion. The movement of the threaded block 126 causes the impact block 1212 and the rubber pad 1213 to move. The movement of the rubber pad 1213 impacts the elastic block 1214 and causes it to vibrate. The vibration of the elastic block 1214 causes the filter screen 122 to vibrate, thereby allowing the water to be filtered quickly from the filter screen 122, which improves the working efficiency of the filter screen 122.

[0039] For details, please refer to Figure 2 , Figure 3 , Figure 6 The inside of the collecting shell 121 is fixedly fitted with a bearing 125, and the inner ring of the bearing 125 is fixedly fitted with a screw 124.

[0040] In this embodiment, the bearing 125 is designed to support the rotation of the screw 124.

[0041] For details, please refer to Figure 7 The groove 1210 is provided with a ball bearing 1211 inside, and the ball bearing 1211 contacts the guide rod 129.

[0042] In this embodiment, by designing the ball bearing 1211, the friction between the wear-resistant sleeve 128 and the guide rod 129 can be reduced.

[0043] Working principle: Before using the device, rotate the cover 1112. The rotation of the cover 1112 causes a threaded movement with the oil inlet 1111, resulting in relative displacement of the cover 1112. The cover 1112 then separates from the oil inlet 1111, allowing lubricating oil to be poured from the oil inlet 1111 into the sliding rod 117. Then, the cover 1112 is installed back into the oil inlet 1111, thus lubricating components such as the guide block 118 and the guide rod 1110. Then, the cylinder 114 is activated. The cylinder rod 115 moves upward, which in turn moves the baffle 116 upward. The baffle 116 moves upward, which in turn moves the sliding rod 117 upward. The sliding rod 117 moves upward, which in turn moves the guide rod 1110, the oil inlet 1111, and the cover 1112 upward. As the sliding rod 117 moves upward, the telescopic sleeve 119 extends and retracts. After the baffle 116 and other components move upward to the designated position, the baffle 116 can prevent water from splashing onto the ground, making the device easy to use.

[0044] When the device is in use, concrete aggregate is placed on conveyor belt 1, and then the first water pump 8 is started. The first water pump 8 pumps water from water tank 5 into water collection shell 9. The water in water collection shell 9 flows into nozzle 10, and nozzle 10 sprays water onto the concrete aggregate. Collection shell 121 can collect wastewater on conveyor belt 1, and filter screen 122 can filter the wastewater. Then, the second water pump 1217 is started to pump water from collection shell 121 into water tank 5, thereby recycling the wastewater and reusing it. When wastewater needs to be filtered quickly from filter screen 122, motor 123 is started. Motor 123 drives screw 124 to rotate, and screw 124 rotates with the thread. The threaded block 126 undergoes a threaded motion, which in turn causes the threaded block 126 to undergo relative displacement. The movement of the threaded block 126 drives the moving block 127 and the impact block 1212 to move. The movement of the moving block 127 drives the wear-resistant sleeve 128 to move. The movement of the wear-resistant sleeve 128 drives the groove 1210 to move. The movement of the groove 1210 drives the ball 1211 to move. The movement of the impact block 1212 drives the rubber pad 1213 to move. The movement of the rubber pad 1213 impacts the elastic block 1214, which in turn causes the elastic block 1214 to vibrate. The vibration of the elastic block 1214 causes the filter screen 122 to vibrate, which in turn allows water to be filtered quickly from the filter screen 122, thereby improving the working efficiency of the filter screen 122.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
