Description

Technical Field

[0001] The invention relates to the technical field of concrete mixing, and in particular to a high-precision concrete proportioning mixing device. Background Art

[0002] When producing concrete, a mixing device is needed to replace manual work to mix cement, river sand, gravel and water according to a certain mix ratio. When the mixing device mixes cement, river sand, gravel and water, it is necessary to add clean water according to the required concentration of the concrete. Therefore, after the concrete is mixed, clean water needs to be added according to the concentration of the concrete. Technical inspiration for the mixing device;

[0003] Research on mixing devices has revealed the following problems:

[0004] During the mixing process of concrete, the mixing device needs to add clean water into the concrete according to the mixing conditions of the concrete. However, the mixing device usually adds water manually, which is prone to deviations during the manual addition process, resulting in deviations in the overall hardness of the concrete after mixing, making it impossible for the mixing device to add clean water with high precision.

[0005] At present, CN202111385446.7 in the prior art discloses a premixing device for concrete production and processing. The collecting box of the invention is slidably arranged on the inner side of the hopper in the vertical direction, the filter disc is connected to the flushing mechanism, and the height of the upper surface of the filter disc decreases from the center of the filter disc to the edge of the filter disc; the lower opening of the soft cover corresponds to the inner side of the collecting box, and the upper opening of the soft cover corresponds to the inner side of the hopper. The inner diameter and outer diameter of the soft cover gradually increase from bottom to top. This application can facilitate the cleaning of concrete attached to the inner wall of the hopper;

[0009] Furthermore, the motor is electrically connected to the power supply through a power cord, and the motor drives the stirring bracket to rotate 360° through a belt. The belt and the stirring bracket are both arranged inside the hopper, and the hopper is concavely arranged, and a transmission mechanism is provided inside the hopper for adding clean water to the concrete.

[0010] Furthermore, a groove is provided on the outer side of the stirring bracket, and 2-5 stirring brackets are distributed inside the hopper.

[0012] Furthermore, the blades are matched with the rotating shaft, and there are more than 6 groups of blades and the rotating shaft. The blades rotate 360 ​​degrees on the inner side of the stirring bracket through the rotating shaft. The blades in each group are horizontally slidably fitted, and the fitting length between each group of blades is less than 3 cm.

[0013] Furthermore, the water tank is filled with clean water, the clean water is below the side of the water outlet pipe, the lower end of the water outlet pipe is 1-3 cm away from the clean water level line, and the water outlet pipe is connected to the inside of the hopper.

[0014] Furthermore, the interior of the sleeve is hollow and divided into two sections. The deformation layer and the sliding frame are respectively located in the two sections of the sleeve. The section where the sliding frame is located is arranged in a transverse "T" shape, and the two sections of the sleeve are connected.

[0015] Furthermore, the upper end of the sliding frame is horizontally slidably fitted with the inner wall of the sleeve, the sliding frame is made of rubber, and the sliding frame is matched with a heavy object, and the heavy object is a weight of 100-200g.

[0016] Furthermore, the deformation layer is arranged in an overall shape, the deformation layer is in the sliding state of the water tank, the deformation layer is made of rubber material, the lower end of the deformation layer and the upper end of the stirring bracket are vertically slid and squeezed, and both sides of the deformation layer are slidably nested in the interior of the sleeve.

[0018] Furthermore, the upper end of the lower push rod slides inside the slide rail, and the slide rail is vertically arranged. When the lower push rod slides upward, the upper push rod swings at an inclined angle.

[0019] Furthermore, one end of the upper push rod is located on the side of the rotating bearing, and the upper push rod is 2-5 cm away from the center position of the rotating bearing. When the upper push rod swings at an inclined angle, the rotating bearing swings at an angle.

[0020] Furthermore, the second swing arm is spaced 2-3 cm from the water outlet pipe, and the second swing arm and the first swing arm are both arranged in a transverse "V" shape. A groove is provided on the inner side of the second swing arm, and the groove runs through the interior of the second swing arm, and the slide slides inside the groove.

[0021] Beneficial effects:

[0022] 1. The motor drives the mixing bracket to rotate through the belt. When the mixing bracket rotates, the concrete impacts the outside of the blades. Due to the impact of the concrete, the blades rotate 360° through the rotating shaft. Since each group of blades is horizontally sliding and fitting, when one of the blades rotates, the blades fit each other and drive each other, so that the inner blades of the mixing bracket rotate 360°. When the blades rotate, they can assist the mixing bracket to further mix the concrete. At the same time, the blades and the mixing bracket form a cross-staggered mixing as a whole, which improves the mixing efficiency of the concrete;

[0023] 2. When the concrete sand and gravel content inside the hopper is large, the concrete texture is relatively hard at this time. During the mixing process of the concrete, the concrete creeps upwards by the mixing bracket, and the upper end of the concrete is squeezed to the upper end of the weight. The weight drives the sliding bracket to slide upwards. When the upper end of the sliding bracket slides toward the side of the deformation layer inside the casing, the pressure inside the casing is large, while the pressure outside the casing is small. Therefore, the sliding bracket can assist the deformation layer to slide toward the outside of the casing. At the same time, the deformation layer is bent as a whole at this time, and the bending angle is more than 35°. When the mixing bracket rotates to the lower end of the deformation layer, the upper end of the mixing bracket can be squeezed to the lower end of the deformation layer, and the deformation layer slides upward as a whole. At this time, the clean water inside the water tank cannot be discharged through the outlet pipe;

[0024] 3. When the concrete inside the hopper is soft, the concrete cannot be squeezed to the lower end of the weight when it creeps upward. Therefore, the weight drives the sliding frame to slide downward from the inside of the casing by using the gravity of the weight. The external force forces the air volume inside the casing to increase, so that the casing pressure becomes smaller, and a pressure difference is formed between the casing and the external atmospheric pressure. The pressure difference acts on the liquid surface to form a pressure difference. At this time, the pressure difference can assist the two sides of the deformation layer to slide toward the inside of the casing, so that the deformation layer is horizontally straightened as a whole, and the deformation layer is in a "one" state. At this time, the deformation layer is 1-3cm away from the lower end of the stirring bracket;

[0025] 4. The upper end of the stirring bracket can be squeezed to the lower end of the deformation layer, and the deformation layer slides upward as a whole. The lower push rod slides upward synchronously inside the slide rail, and the lower push rod drives the upper push rod to swing upward. The upper push rod drives the rotating bearing to swing at an angle. Since there is a gap between the stirring brackets, there is a gap in the squeezing of the stirring bracket on the lower end of the deformation layer. When the lower end of the deformation layer loses the squeezing of the stirring bracket, the water pressure inside the water tank returns to its original position as a whole. At this time, the lower push rod and the lower push rod slide vertically downward, and the rotating bearing swings back and forth as a whole;

[0026] 5. The rotating bearing can drive the second swing arm and the first swing arm to swing vertically back and forth. During the swinging process of the second swing arm, the inner slide of the second swing arm slides on the inner side of the second swing arm, and the second swing arm can drive the clean water to flow upward, thereby assisting the clean water inside the water tank to enter the inside of the water outlet pipe, and the clean water enters the inside of the hopper through the water outlet pipe, so that the mixing device can add clean water when the concrete texture is harder.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] Example:

[0039] As attached Figure 1 To Attachment Figure 8 As shown:

[0040] Embodiment 1: A high-precision concrete mixing device comprises a mixer 1, wherein a motor 101 and a hopper 102 are provided at the end of the mixer 1, a belt 103 is rotatably wrapped around the driving end of the motor 101, and a mixing bracket 2 is rotatably disposed inside the belt 103;

[0041] Wherein: the motor 101 is electrically connected to the power supply through a power line, and the motor 101 drives the stirring bracket 2 to rotate 360 ​​degrees through a belt 103;

[0042] The hopper 102, the belt 103 and the stirring support 2 are all arranged inside the hopper 102. The hopper 102 is arranged in a concave shape, and a transmission mechanism for adding clean water to the concrete is arranged inside the hopper 102.

[0043] A stirring bracket 2, the outer side of the stirring bracket 2 is provided with a groove, and 2-5 stirring brackets 2 are distributed inside the hopper 102;

[0044] Example 2: Refer to the attached manual Figure 1-5It can be known that the difference between Example 2 and Example 1 is that the transmission mechanism includes a rotating shaft 201, blades 202, a water tank 3, a water outlet pipe 301, a sleeve 302, a sliding frame 303, a weight 304 and a deformation layer 4, the rotating shaft 201 is hinged to the inner side of the stirring bracket 2, the blade 202 swings on the outer side of the rotating shaft 201, the water tank 3 is installed at the upper end inside the hopper 102, the water outlet pipe 301 runs through the side above the water tank 3, the sleeve 302 is installed on both sides of the lower end of the water tank 3, the sliding frame 303 slides and extends to the bottom of the sleeve 302, the weight 304 is suspended at the lower end of the sliding frame 303, and the deformation layer 4 is slidably nested in the inner side of the sleeve 302;

[0045] Among them: the rotating shaft 201 and the blades 202, the blades 202 and the rotating shaft 201 are matched, the blades 202 and the rotating shaft 201 are provided with more than 6 groups, the blades 202 rotate 360 ​​degrees on the inner side of the stirring bracket 2 through the rotating shaft 201, and the blades 202 are horizontally slidably fitted between each group, and the fitting length between each group of blades 202 is less than 3cm, as shown in the attached manual Figure 4 As shown;

[0046] When the mixing bracket 2 rotates, the concrete impacts the outer side of the blades 202, and the blades 202 rotate 360° through the rotating shaft 201. Since each group of blades 202 is horizontally slidably fitted, the inner blades 202 of the mixing bracket 2 all rotate 360°.

[0047] The water tank 3 and the water outlet pipe 301, the water tank 3 is filled with clean water, the clean water is below the side of the water outlet pipe 301, the lower end of the water outlet pipe 301 is 1-3 cm away from the clean water level line, and the water outlet pipe 301 is connected to the inside of the hopper 102;

[0048] The sleeve 302 is hollow inside and is divided into two sections. The deformation layer 4 and the sliding frame 303 are located in the two sections of the sleeve 302 respectively. The section where the sliding frame 303 is located is arranged in a transverse "T" shape. The two sections of the sleeve 302 are connected.

[0049] The sliding frame 303 and the weight 304, the upper end of the sliding frame 303 is horizontally slidably fitted with the inner wall of the sleeve 302, the sliding frame 303 is made of rubber, the sliding frame 303 and the weight 304 are matched, and the weight 304 is a weight of 100-200g;

[0050] When the sliding frame 303 slides downward from the inside of the sleeve 302, the external force forces the air volume inside the sleeve 302 to increase, so that the pressure of the sleeve 302 decreases, and a pressure difference is formed between the sleeve 302 and the external atmospheric pressure. The pressure difference acts on the liquid surface to form a pressure difference. At this time, the pressure difference can assist the two sides of the deformable layer 4 to slide toward the inside of the sleeve 302. The principle of extracting liquid medicine with a syringe can be referred to;

[0051] When the upper end of the sliding frame 303 slides inside the sleeve 302 toward one side of the deformable layer 4, the pressure inside the sleeve 302 is high, while the pressure outside the sleeve 302 is low. Thus, the sliding frame 303 can assist the deformable layer 4 to slide toward the outside of the sleeve 302, which can be referred to the principle of injecting liquid medicine with a syringe.

[0052] The deformation layer 4 is arranged in a shape of a workpiece as a whole, and the deformation layer 4 is in the sliding state of the water tank 3. The deformation layer 4 is made of rubber. The lower end of the deformation layer 4 is vertically slid and squeezed with the upper end of the stirring bracket 2, and the two sides of the deformation layer 4 are slidably nested in the interior of the sleeve 302;

[0053] Wherein: the motor 101 drives the mixing bracket 2 to rotate through the belt 103. When the mixing bracket 2 rotates, the concrete impacts the outer side of the blade 202. Due to the impact force of the concrete, the blade 202 rotates 360° through the rotating shaft 201. Since each group of blades 202 is horizontally slidably fitted, when one of the blades 202 rotates, the blades 202 are fitted and driven to each other, so that the inner blades 202 of the mixing bracket 2 rotate 360°. When the blades 202 rotate, they can assist the mixing bracket 2 to further mix and stir the concrete. At the same time, the blades 202 and the mixing bracket 2 form a cross-staggered mixing as a whole, thereby improving the concrete mixing efficiency.

[0054] When the concrete sand and gravel content inside the hopper 102 is relatively large, the concrete texture is relatively hard at this time. During the mixing process of the concrete, the concrete creeps upward by the mixing bracket 2, and the upper end of the concrete is squeezed to the upper end of the weight 304. The weight 304 drives the sliding frame 303 to slide upward. When the upper end of the sliding frame 303 slides toward the side of the deformation layer 4 inside the sleeve 302, the pressure inside the sleeve 302 is large, while the pressure outside the sleeve 302 is small. Therefore, the sliding frame 303 can assist the deformation layer 4 to slide toward the outside of the sleeve 302. At the same time, the deformation layer 4 is in a bent state as a whole at this time, and the bending angle is more than 35°, so that when the mixing bracket 2 rotates to the lower end of the deformation layer 4, the upper end of the mixing bracket 2 can be squeezed to the lower end of the deformation layer 4, and the deformation layer 4 slides upward as a whole.

[0055] When the concrete inside the hopper 102 is soft, the concrete cannot be squeezed to the lower end of the weight 304 when it creeps upward. Therefore, the weight 304 is used to drive the sliding frame 303 to slide downward from the inside of the sleeve 302. The external force forces the air volume inside the sleeve 302 to increase, so that the pressure of the sleeve 302 becomes smaller, and a pressure difference is formed between the sleeve 302 and the external atmospheric pressure. The pressure difference acts on the liquid surface to form a pressure difference. At this time, the pressure difference can assist the two sides of the deformation layer 4 to slide toward the inside of the sleeve 302, so that the deformation layer 4 is horizontally straightened as a whole, and the deformation layer 4 is in a "one" state. At this time, the deformation layer 4 is 1-3 cm away from the lower end of the stirring bracket 2. At this time, the clean water inside the water tank 3 cannot be discharged through the outlet pipe;

[0056] Example 3: Refer to the attached manual Figure 5-8 It can be known that the difference between Example 3 and Examples 1 and 2 is that the transmission mechanism includes a lower push rod 401, a slide rail 402, an upper push rod 402, a rotary bearing 5, a first swing arm 501, a second swing arm 502 and a slide plate 503, the lower push rod 401 is embedded in the upper end of the deformation layer 4, the slide rail 402 is installed inside the water tank 3, the upper push rod 403 slides on the upper end of the lower push rod 401, the rotary bearing 5 swings at the middle position inside the water tank 3, the first swing arm 501 and the second swing arm 502 swing on the left and right sides of the rotary bearing 5 respectively, and the slide plate 503 slides on the inner side of the second swing arm 502;

[0057] Among them: a lower push rod 401 and a slide rail 402, the upper end of the lower push rod 401 slides inside the slide rail 402, the slide rail 402 is vertically arranged, when the lower push rod 401 slides upward, the upper push rod 403 swings at an inclined angle;

[0058] The slide rail 402 is arranged vertically, and can limit the sliding direction of the lower push rod 401, so as to prevent the lower push rod 401 from driving the upper push rod 403 to slide left and right;

[0059] The upper push rod 403 has one end located on the side of the rotating bearing 5, and the upper push rod 403 is 2-5 cm away from the center of the rotating bearing 5. When the upper push rod 403 swings at an inclined angle, the rotating bearing 5 swings at an angle, as shown in the attached manual. Figure 8 As shown;

[0060] A first swing arm 501 and a second swing arm 502, the second swing arm 502 is 2-3 cm away from the water outlet pipe 301, the second swing arm 502 and the first swing arm 501 are both arranged in a transverse "V" shape, a groove is provided on the inner side of the second swing arm 502, the groove runs through the interior of the second swing arm 502, and the slide plate 503 slides inside the groove;

[0061] Among them: the upper end of the stirring bracket 2 can be squeezed to the lower end of the deformation layer 4, the deformation layer 4 slides upward as a whole, the lower push rod 401 slides upward synchronously inside the slide rail 402, the lower push rod 401 drives the upper push rod 403 to swing upward, and the upper push rod 403 drives the rotating bearing 5 to swing at an angle. Since there is a gap between the stirring brackets 2, there is a gap between the stirring brackets 2 and the lower end of the deformation layer 4. When the lower end of the deformation layer 4 loses the squeezing of the stirring bracket 2, the water pressure of the clean water inside the water tank 3 returns to its original position as a whole. At this time, the lower push rod 401 and the lower push rod 403 slide vertically downward, and the rotating bearing 5 swings back and forth as a whole;

[0062] The rotating bearing 5 can drive the second swing arm 502 and the first swing arm 501 to swing vertically back and forth. During the swinging process of the second swing arm 502, the inner slide plate 503 of the second swing arm 502 slides on the inner side of the second swing arm 502, and the second swing arm 502 can drive the clean water to flow upward, thereby assisting the clean water in the water tank 3 to enter the inside of the water outlet pipe 301. The clean water enters the inside of the hopper 102 through the water outlet pipe 301, so that this mixing device can add clean water when the concrete texture is harder.
