Description
Technical Field
[0001] This utility model relates to the technical field of screening devices for mortar production, and in particular to a screening device for mortar production. Background Technology
[0002] Screening devices for mortar production are indispensable key equipment in the mortar production process. They are used to classify the mixed mortar according to particle size or remove impurities, ensuring the quality and performance of the final product. The efficiency and precision of the screening device directly affect the uniformity and applicability of the mortar, and have a direct impact on the construction efficiency and project quality in the construction industry.
[0003] During the use of current mortar production screening equipment, staff often find that fine particles of mortar raw materials clump together during storage. As a result, during the screening process, the clumps are screened out as coarse materials, and the fine materials are used as coarse materials, leading to a waste of raw materials. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a screening device for mortar production.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a screening device for mortar production, comprising a screening box, a feeding hopper fixedly connected to the screening box, two screening plates disposed in the screening box, two receiving boxes detachably installed on the screening box, the receiving boxes being slidably inserted into the screening box, a dispersing structure disposed in the screening box, the dispersing structure mainly consisting of two rotating shafts, both of which are rotatably connected in the screening box, five dispersing rollers fixedly connected to the rotating shafts, three round rollers fixedly connected to the dispersing rollers, a first motor fixedly connected to the screening box, the first motor being fixedly connected to one rotating shaft, and gears fixedly connected to one end of each of the two rotating shafts, the two gears meshing with each other.
[0006] The effect achieved by the above components is as follows: raw materials are fed into the screening box through the feed hopper. The first motor is started, and the output shaft of the first motor drives a rotating shaft and a gear to rotate. This drives two gears to rotate synchronously in opposite directions, which in turn causes the two rotating shafts to rotate synchronously in opposite directions. Furthermore, several dispersing rollers on the rotating shafts disperse the clumps of raw materials. The round rollers can improve the dispersing effect. The dispersed raw materials fall onto two screening plates for screening. The screen holes of the upper screening plate are larger than those of the lower screening plate, thus avoiding the situation where fine particles of mortar raw materials clump together during storage. Therefore, during the screening process, the clumps of raw materials will be screened out as coarse materials, and the original fine materials will be used as coarse materials, resulting in the waste of raw materials.
[0007] Preferably, the screening box has two rotating rods rotatably connected, and a baffle is fixedly connected to each rotating rod.
[0008] The effect achieved by the above components is that the two baffles can limit the material and prevent it from falling directly from both sides of the two rotating shafts, so as to prevent it from being dispersed by the dispersing roller and the round roller.
[0009] Preferably, two first springs are sleeved on the rotating rod, one end of the first spring is fixedly connected to the baffle, and the other end of the first spring is fixedly connected to the inner wall of the screening box.
[0010] The effect achieved by the above components is as follows: when the raw material falls onto the baffle, it will press the rotating rod to rotate, causing the first spring to twist. The spring then rebounds and resets, moving the raw material closer to the dispersing rod, thus improving the dispersing effect.
[0011] Preferably, a second spring is fixedly connected to the baffle, and one end of the second spring is fixedly connected to the inner wall of the screening box.
[0012] The effect achieved by the above components is that the rebound force of the second spring further supports the baffle, increasing the frequency and effect of the baffle's reciprocating vibration.
[0013] Preferably, the screening box is provided with a vibration structure, which mainly consists of two sliding grooves. Both sliding grooves are opened on one inner wall of the screening box, and a slider is slidably connected in the sliding groove. The slider is fixedly connected to the screening plate.
[0014] The effect achieved by the above components is that the screening plate can be moved up and down by sliding the slider, thereby improving the screening effect.
[0015] Preferably, a third spring is fixedly connected in the groove, and one end of the third spring is fixedly connected to the slider.
[0016] The effect achieved by the above components is as follows: when the slider is slid upward, it will compress the third spring and contract. Therefore, when you release the hand at this time, the rebound force of the third spring will act on the slider, causing the screening plate to oscillate continuously, thereby further improving the screening effect.
[0017] Preferably, a connecting rod is fixedly connected to the screening plate, and a connecting block is fixedly connected to both connecting rods.
[0018] The effect achieved by the above components is that the two connecting rods can be moved synchronously by moving the connecting block up and down, thereby enabling the two screening plates to screen synchronously.
[0019] Preferably, a third motor is fixedly connected to the screening box, a round shaft is fixedly connected to the output shaft of the third motor, a turntable is fixedly connected to one end of the round shaft, a round rod is fixedly connected to the turntable, and the round rod is slidably connected to the connecting block.
[0020] The effect achieved by the above components is as follows: when the third motor is started, the output shaft of the third motor drives the round shaft to rotate, which in turn drives the turntable to rotate, causing the round rod to make circular motion, which in turn drives the connecting block to move up and down, making the operation more convenient.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting a dispersing structure, the raw materials are fed into the screening box through the feed hopper. The first motor is started, and the output shaft of the first motor drives a rotating shaft and a gear to rotate. Therefore, the two gears will rotate synchronously in opposite directions, which in turn causes the two rotating shafts to rotate synchronously in opposite directions. Furthermore, several dispersing rollers on the rotating shafts disperse the lumpy raw materials. The round rollers can improve the dispersing effect. The dispersed raw materials fall onto two screening plates for screening at once. The screen holes of the upper screening plate are larger than those of the lower screening plate, thereby avoiding the situation where fine particles of mortar raw materials clump together during storage. Therefore, during the screening process, the lumpy raw materials will be screened out as coarse materials, and the original fine materials will be used as coarse materials, resulting in the waste of raw materials.

[0027] Example 1, such as Figure 1 and Figure 2 As shown, a screening device for mortar production includes a screening box 1, a feed hopper 2 fixedly connected to the screening box 1, two screening plates 3 arranged in the screening box 1, two receiving boxes 4 detachably installed on the screening box 1, and a receiving box 5 slidably inserted on the screening box 1.
[0028] Reference Figure 3 The screening box 1 is equipped with a dispersing structure 6, which mainly consists of two rotating shafts 61. Both rotating shafts 61 are rotatably connected to the screening box 1. Five dispersing rollers 62 are fixedly connected to the rotating shafts 61, and three round rollers 63 are fixedly connected to the dispersing rollers 62. A first motor 65 is fixedly connected to the screening box 1 and is fixedly connected to one of the rotating shafts 61. Gears 64 are fixedly connected to one end of each of the two rotating shafts 61. The two gears 64 mesh with each other. The raw material is fed into the screening box 1 through the feed hopper 2. The first motor is started. The output shaft of the first motor 65 drives a rotating shaft 61 and a gear 64 to rotate, thus causing the two gears 64 to rotate synchronously in opposite directions. This, in turn, causes the two rotating shafts 61 to rotate synchronously in opposite directions. Furthermore, several dispersing rollers 62 on the rotating shafts 61 disperse the clumps of raw materials. The round rollers 63 can improve the dispersing effect. The dispersed raw materials fall onto two screening plates 3 for screening. The sieve holes of the upper screening plate 3 are larger than those of the lower screening plate, thereby avoiding the clumping of fine particles in the mortar raw materials during storage. Therefore, during the screening process, agglomerated raw materials will be screened out as coarse materials, thus wasting the original fine materials. The screening box 1 contains two rotating rods 66, each with a baffle 67 fixedly connected to it. The baffles 67 limit the material's movement, preventing it from falling directly from the sides of the two rotating shafts 61. To prevent the material from being dispersed by the dispersing rollers 62 and 63, two first springs 68 are fitted onto the rotating rods 66, with one end of each spring fixedly connected to the baffle 67. On screen 7, the other end of the first spring 68 is fixedly connected to the inner wall of the screening box 1. When the raw material falls onto the baffle 67, it will press the rotating rod 66 to rotate, causing the first spring 68 to twist. It then rebounds and resets, driving the raw material closer to the dispersing rod 62, thus improving the dispersing effect. A second spring 69 is fixedly connected to the baffle 67. One end of the second spring 69 is fixedly connected to the inner wall of the screening box 1. The rebound force of the second spring 69 further supports the baffle 67, increasing the frequency and effect of the reciprocating vibration of the baffle 67.
[0029] Reference Figure 1 and Figure 4The screening box 1 is equipped with a vibration structure 7, which mainly consists of two sliding grooves 71. Both grooves 71 are located on one inner wall of the screening box 1. A slider 72 is slidably connected to each groove 71, and the slider 72 is fixedly connected to the screening plate 3. The sliding slider 72 can move the screening plate 3 up and down by sliding the slider 72, thereby improving the screening effect. A third spring 73 is fixedly connected to each groove 71, with one end of the third spring 73 fixedly connected to the slider 72. When the slider 72 is slid upwards, it compresses the third spring 73. When the slider 72 is released, the rebound force of the third spring 73 acts on the slider 72, causing the screening plate 3 to vibrate continuously, further improving the screening effect. The screening plate 3 is fixedly connected to... There are two connecting rods 75, and two connecting blocks 74 are fixedly connected to the connecting rods 75. The two connecting rods 75 can be moved synchronously by moving the connecting blocks 74 up and down, thereby causing the two screening plates 3 to screen synchronously. A third motor 78 is fixedly connected to the screening box 1. A round shaft 76 is fixedly connected to the output shaft of the third motor 78. A turntable 77 is fixedly connected to one end of the round shaft 76. A round rod 79 is fixedly connected to the turntable 77. The round rod 79 is slidably connected to the connecting block 74. When the third motor 78 is started, the output shaft of the third motor 78 drives the round shaft 76 to rotate, which in turn drives the turntable 77 to rotate, causing the round rod 79 to make circular motion, which in turn drives the connecting block 74 to move up and down, making the operation more convenient.
[0030] Working principle: Raw materials are fed into screening box 1 through hopper 2. The first motor 65 is started, and its output shaft drives a rotating shaft 61 and a gear 64 to rotate. This causes the two gears 64 to rotate synchronously in opposite directions, which in turn causes the two rotating shafts 61 to rotate synchronously in opposite directions. Furthermore, several dispersing rollers 62 on the rotating shafts 61 disperse any clumps of raw materials. The round rollers 63 enhance the dispersing effect. The dispersed raw materials fall onto two screening plates 3 for screening. The upper screening plate 3 has larger sieve holes than the lower one, thus preventing the mortar raw materials from clumping together due to fine particles during storage. During screening, clumps of raw materials are treated as coarse particles, resulting in waste. Two baffles 67 limit the flow of raw materials, preventing them from falling directly from the sides of the two rotating shafts 61. Instead, the raw materials are dispersed by the dispersing rollers 62 and the round rollers 63, and fall onto the baffles 67. When the rotating rod 66 is pressed, it rotates, causing the first spring 68 to twist. The spring then rebounds and moves the raw material closer to the dispersing roller 62, improving the dispersing effect. The rebound force of the second spring 69 further supports the baffle 67, increasing the frequency and effect of its reciprocating vibration. The sliding block 72 can be used to move the screening plate 3 up and down to improve the screening effect. When the sliding block 72 is moved upwards, it compresses the third spring 73, causing it to contract. Releasing the hand at this point causes the rebound force of the third spring 73 to act on the sliding block 72, causing the screening plate 3 to oscillate continuously, further improving the screening effect. The connecting block 74 can be moved up and down to move the two connecting rods 75 synchronously, thus causing the two screening plates 3 to screen synchronously. The third motor 78 is started, and its output shaft drives the round shaft 76 to rotate, which in turn drives the turntable 77 to rotate, causing the round rod 79 to move in a circular motion, which in turn drives the connecting block 74 to reciprocate up and down, making operation more convenient.
