Description

Technical Field

[0001] The utility model relates to the technical field of sand screening equipment, in particular to a drum type classification sand screening equipment for construction engineering. Background Art

[0002] The drum sand screen is a device commonly used for screening and grading granular materials such as sand. In construction, a large amount of sand is needed as a building material. By screening the sand, the sand can be graded and classified according to different particle sizes according to usage requirements.

[0003] Chinese patent "A sand screening device for construction engineering" authorization announcement number "CN 218691303U" This sand screening device for construction engineering construction starts the rotating motor to pour the sand raw material into the hopper. The rotating motor drives the rotating shaft to rotate, so that the spiral blade drives the sand raw material to move quickly to the left, and then the sand raw material enters the filter screen for screening to avoid sand accumulation at the feed inlet and cause blockage.

[0004] Although the above scheme can prevent the feed port from being blocked, some sand will contain a certain amount of moisture. When the sand is screened using a filter, some sand will adhere to the mesh of the filter, causing the diameter of the filter mesh to become smaller or blocked, thereby affecting the screening efficiency.

[0005] Therefore, a drum type classification and screening sand equipment for construction engineering is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a drum-type sand classification and screening equipment for construction projects in order to solve the above-mentioned problem, which improves the problem that some sand contains a certain amount of moisture. When the sand is screened by a filter, some sand will adhere to the mesh of the filter, causing the diameter of the filter mesh to become smaller or blocked, thereby affecting the screening efficiency.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: a drum-type classification and screening sand equipment for construction engineering, comprising: a mounting frame, a fixed frame is fixedly connected to the inner side of the mounting frame, a feed hopper is installed on one side of the mounting frame, a screening drum is rotatably connected to the inner wall of the fixed frame, a mounting plate is fixedly connected to one side of the top of the mounting frame, a motor is fixedly connected to one side of the mounting plate, the output shaft of the motor passes through the mounting plate and is fixedly connected to the rotating shaft of the screening drum, and a cleaning mechanism is provided on the surface of the screening drum; wherein, the cleaning mechanism comprises a cam fixedly connected to the surface of the motor output shaft, a moving plate is slidably connected to the other side of the mounting plate, one end of the moving plate passes through the mounting plate and is fixedly connected to the trigger rod, and the bottom end of the moving plate is fixedly connected to slapping plates distributed in equal rows, and a cleaning component is provided on the surface of the screening drum.

[0008] Preferably, the cleaning assembly includes a cleaning brush, the other side of the mounting plate is rotatably connected to a rotating rod, the lower end of the surface of the rotating rod is fixedly connected to the top of the cleaning brush, one end of the rotating rod passes through the mounting plate and is fixedly connected to a fixed block, the bottom end of the fixed block is slidably connected to a slider, the bottom end of the slider is hinged to a connecting rod, and the other end of the connecting rod is fixedly connected to the surface of the trigger rod. When the moving plate reciprocates up and down, under the action of the connecting rod, the slider and the fixed block, it is conducive to the rotating rod driving the cleaning brush to reciprocate to clean the sieving drum after the beating, so that the sand in the mesh falls off, thereby avoiding the clogging of the mesh of the sieving drum and ensuring the screening effect of the sieving drum.

[0009] Preferably, a U-shaped rod is fixedly connected to the other side of the top of the mounting frame, a fixed rod is fixedly connected to the bottom of the U-shaped rod, and cleaning rods distributed in equal rows are fixedly connected to one side of the fixed rod. When the cleaning brush reciprocates, the cleaning rod collides with the cleaning brush to deform the bristles of the cleaning brush, which is conducive to dropping the sand adhered to the bristles when the cleaning brush is cleaning, thereby ensuring the cleaning effect of the cleaning brush on the screening cylinder.

[0010] Preferably, a slide groove is provided on the surface of the mounting plate, the surface of the movable plate is slidably connected to the inner wall of the slide groove, and a spring is fixedly connected between the bottom end of the movable plate and the inner wall of the slide groove, which is conducive to ensuring that the bottom end of the movable plate is in better contact with the surface of the cam and ensuring the stability of the device during operation.

[0011] Preferably, a contact pad is fixedly connected to the bottom end of the slapping plate, and the contact pad is a rubber component, which is beneficial for protecting the screening cylinder and avoiding damage caused by slapping.

[0012] Preferably, the other end of the cleaning rod is in the shape of a flat-topped cone, which is conducive to better deformation of the bristles of the cleaning brush.

[0013] Preferably, the top end of the U-shaped rod is fixedly connected to a limiting rod, and the top end of the limiting rod passes through the moving plate, which is conducive to limiting the movement of the moving plate and ensuring the stability of the moving plate when driving the flapping plate to move.

[0015] The beneficial effects of the utility model are:

[0016] 1. When the screening drum classifies and screens the sand, the setting of the cleaning mechanism, under the action of the cam, enables the moving plate to drive the slapping plate to continuously move up and down to slap the screening drum, which is conducive to vibrating the screening drum, so that the sand in the mesh is loosened and falls. At the same time, the setting of the cleaning component, when the moving plate moves up and down, under the action of the connecting rod, the slider and the fixed block, is conducive to the rotating rod driving the cleaning brush to reciprocate to clean the slapped screening drum, so that the sand in the mesh falls, thereby avoiding the clogging of the screening drum mesh and ensuring the screening effect of the screening drum;

[0017] 2. When the cleaning brush reciprocates, the cleaning rod collides with the cleaning brush to deform the bristles of the cleaning brush, which is conducive to the fall of sand adhering to the bristles of the cleaning brush when cleaning, ensuring the cleaning effect of the cleaning brush on the screening cylinder.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-5 As shown, a drum-type classification and screening sand equipment for construction engineering comprises: a mounting frame 1, a fixed frame 2 is fixedly connected to the inner side of the mounting frame 1, a feed hopper 3 is installed on one side of the mounting frame 1, a screening drum 4 is rotatably connected to the inner wall of the fixed frame 2, a mounting plate 5 is fixedly connected to one side of the top of the mounting frame 1, a motor 6 is fixedly connected to one side of the mounting plate 5, an output shaft of the motor 6 passes through the mounting plate 5 and is fixedly connected to the rotating shaft of the screening drum 4, and a cleaning mechanism 7 is arranged on the surface of the screening drum 4; wherein, the cleaning mechanism 7 comprises a cam 701 fixedly connected to the surface of the output shaft of the motor 6, a moving plate 702 is slidably connected to the other side of the mounting plate 5, one end of the moving plate 702 passes through the mounting plate 5 and is fixedly connected to the trigger rod 703, and a beating plate 704 distributed in equal rows is fixedly connected to the bottom end of the moving plate 702, and a cleaning assembly 705 is arranged on the surface of the screening drum 4.

[0026] When screening the sand, pour the sand from the feed hopper 3 into the screening drum 4, start the motor 6 through the controller, so that the output shaft of the motor 6 drives the screening drum 4 to rotate counterclockwise to screen the sand, and the sand smaller than the mesh diameter of the screening drum 4 will fall into the fixed frame 2 and be discharged through the fixed frame 2, and the sand larger than the diameter of the screening drum 4 will be discharged through the screening drum 4. At this time, the sand classification is completed, and the cleaning component 705 runs synchronously while the sand is being screened.

[0027] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the cleaning assembly 705 includes a cleaning brush 7052, and the other side of the mounting plate 5 is rotatably connected to a rotating rod 7051, the lower end of the surface of the rotating rod 7051 is fixedly connected to the top of the cleaning brush 7052, one end of the rotating rod 7051 passes through the mounting plate 5 and is fixedly connected to a fixed block 7053, the bottom end of the fixed block 7053 is slidably connected to a slider 7054, the bottom end of the slider 7054 is hinged to a connecting rod 7055, and the other end of the connecting rod 7055 is fixedly connected to the surface of the trigger rod 703.

[0028] When the output shaft of the motor 6 rotates, the cam 701 is driven to rotate synchronously. When the cam 701 rotates to the highest point and contacts the bottom end of the movable plate 702, the movable plate 702 moves upward to the highest point. When the cam 701 rotates to the lowest point and contacts the bottom end of the movable plate 702, the movable plate 702 drives the trigger rod 703 to move downward under the action of its own gravity. Therefore, when the cam 701 rotates, the trigger rod 703 will drive the movable plate 702 and the slapping plate 704 to move up and down. When the slapping plate 704 moves downward, it will slap the screening drum 4, causing the screening drum 4 to vibrate, thereby loosening the sand in the mesh and falling off.

[0029] At the same time, when the trigger rod 703 moves up and down, it will drive the connecting rod 7055 to move up and down synchronously, and under the action of the slider 7054 and the fixed block 7053, the up and down movement of the connecting rod 7055 will drive the rotating rod 7051 to rotate back and forth, thereby driving the cleaning brush 7052 to rotate back and forth to clean the screening cylinder 4 after being tapped. The bristles of the cleaning brush 7052 have a certain flexibility and can be deformed. The cleaning brush 7052 cleans the sand in the mesh to fall off, thereby avoiding clogging of the mesh of the screening cylinder 4.

[0030] like Figure 3 , Figure 4 and Figure 5 As shown, a U-shaped rod 7056 is fixedly connected to the other side of the top of the mounting frame 1, a fixing rod 7057 is fixedly connected to the bottom end of the U-shaped rod 7056, and cleaning rods 7058 distributed in equal rows are fixedly connected to one side of the fixing rod 7057. The other end of the cleaning rod 7058 is in the shape of a flat-top cone. The cleaning rod 7058 is arranged obliquely.

[0031] When the cleaning brush 7052 rotates back and forth, the bristles of the cleaning brush 7052 will constantly collide with the cleaning rod 7058. At this time, the cleaning brush 7052 will be deformed and the sand on the bristles will fall off.

[0032] like Figure 2 As shown, a slide groove 501 is provided on the surface of the mounting plate 5, the surface of the movable plate 702 is slidably connected to the inner wall of the slide groove 501, and a spring 709 is fixedly connected between the bottom end of the movable plate 702 and the inner wall of the slide groove 501. When the movable plate 702 is squeezed and moved upward, the spring 709 is compressed, and when the cam 701 releases the squeeze on the movable plate 702, the spring 709 automatically resets.

[0033] like Figure 4 and Figure 5 As shown, the bottom end of the slapping plate 704 is fixedly connected with a contact pad 7041, which is a rubber member. When the slapping plate 704 slaps the screening drum 4, the contact pad 7041 contacts the screening drum 4 to protect the screening drum 4.

[0034] like Figure 5 As shown, the top of the U-shaped rod 7056 is fixedly connected to the limiting rod 7059, and the top of the limiting rod 7059 passes through the moving plate 702. The inner wall of the moving plate 702 is slidably connected to the surface of the limiting rod 7059.

[0035] When the utility model is used, when screening sand, the sand is poured from the feed hopper 3 into the screening drum 4, and the motor 6 is started by the controller, so that the output shaft of the motor 6 drives the screening drum 4 to rotate counterclockwise to screen the sand, and the sand smaller than the mesh diameter of the screening drum 4 will fall into the fixed frame 2 and be discharged through the fixed frame 2, and the sand larger than the diameter of the screening drum 4 will be discharged through the screening drum 4. At this time, the sand classification is completed. At the same time, when the output shaft of the motor 6 rotates, the cam 701 is driven to rotate synchronously, and under the action of the spring 709 and the self-gravity of the moving plate 702, the trigger rod 703 drives the moving plate 702 and the beating plate 704 move up and down reciprocatingly. When the beating plate 704 moves downward, it will beat the screening cylinder 4, causing the screening cylinder 4 to vibrate, thereby loosening the sand in the mesh and falling off. At the same time, when the trigger rod 703 moves up and down, it will drive the connecting rod 7055 to move up and down synchronously, and under the action of the slider 7054 and the fixed block 7053, the up and down movement of the connecting rod 7055 will drive the rotating rod 7051 to rotate back and forth, thereby driving the cleaning brush 7052 to rotate back and forth, cleaning the screening cylinder 4 after beating, causing the sand in the mesh to fall off, and avoiding clogging of the mesh of the screening cylinder 4.

[0036] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
