Description

Technical Field

[0001] This utility model relates to the field of concrete mixing technology, and in particular to a concrete mixing device that prevents clogging. Background Technology

[0002] A mixing device is a device that mixes raw materials such as lime powder, stones, and water into concrete. When using a mixing device, lime powder, stones, and water are placed inside the mixing device by hand, and then the first motor drives the mixing rod to rotate, which mixes the raw materials evenly, thus facilitating the formation of concrete.

[0003] The inventors discovered in their daily work that the mixing device still has at least the following problems: When using the mixing device, lime powder, stones and water are manually placed inside the mixing device, and then the first motor drives the mixing rod to rotate, and the mixing rod mixes the raw materials evenly to form concrete. However, in actual use, because the raw materials are placed inside the mixing device at once, the stones may accumulate together, which may block the mixing device, thus affecting the formation of concrete to a certain extent. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-clogging concrete mixing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a clog-resistant concrete mixing device, comprising a mixing device body, a first motor fixedly connected to the top of the mixing device body, a mixing rod fixedly connected to the output end of the first motor, a discharge pipe provided at the bottom of the mixing device body, a solenoid valve provided inside the discharge pipe, a feed pipe provided at the top of the mixing device body, a feeding device provided at the top of the mixing device body, a limit device provided on one side of the feed pipe, and the feeding device including a storage tank, the storage tank being fixed to the top of the mixing device body. The storage box has a discharge hole at its bottom, a groove on its inner wall, a baffle slidably connected to the inner wall of the groove, a connecting plate fixedly connected to the end of the baffle away from the discharge hole, a rubber ball fixedly connected to the bottom of the connecting plate, a first damping rod fixedly connected to the side of the connecting plate near the baffle, the end of the first damping rod away from the connecting plate fixedly connected to the side of the discharge hole, a first spring sleeved on the surface of the first damping rod, one end of the first spring fixedly connected to the side of the discharge hole, and the end of the first spring near the first damping rod fixedly connected to the side of the connecting plate.

[0006] The effect achieved by the above components is as follows: When using the feeding device, the stones are placed inside the storage tank, and other raw materials are placed inside the main body of the mixing device. Then, the first motor is started, which drives the mixing rod to rotate. When the mixing rod squeezes the rubber ball, the first spring is stretched, which causes the baffle to slide on the inner wall of the chute, thus exposing the discharge hole. When the mixing rod moves away from the rubber ball, the first spring returns to its original state, which causes the baffle to return to its original position. This allows stones to be added slowly as the mixing rod stirs, thus preventing the stones from piling up to a certain extent.

[0007] Preferably, the inner wall of the storage box is provided with an inclined surface, and a rotating roller is uniformly inserted into the inner wall of the storage box, with the rotating roller located at the top of the inclined surface.

[0008] The effect achieved by the above components is that, because the inner wall of the storage box is provided with symmetrical inclined surfaces, the rotation of the rotating roller can be controlled, which can prevent stones from getting stuck inside the storage box to a certain extent.

[0009] Preferably, a protective sleeve is fixedly connected to one side of the discharge hole. The protective sleeve is fitted onto the surface of the first damping rod and the first spring, and the end of the protective sleeve away from the discharge hole is slidably inserted through and inserted into one side of the connecting plate.

[0010] The effect achieved by the above components is as follows: the protective sleeve prevents the concrete material from coming into contact with the first damping rod and the first spring, thus preventing the material from affecting the stretching and contraction of the first spring to a certain extent.

[0011] Preferably, a connecting frame is fixedly connected to one side of the storage box, a second motor is fixedly connected to one side of the connecting frame, a first pulley is fixedly connected to the output end of the second motor, one side of the first pulley and the end of the rotating roller away from the storage box are fixedly connected, gears are evenly inserted on one side of the storage box, two gears mesh with each other, a second pulley is fixedly attached to the side of the gear away from the storage box, and a connecting belt is sleeved on the surface of the first pulley and the second pulley.

[0012] The effect achieved by the above components is as follows: starting the second motor drives the first pulley and the rotating roller fixedly connected to the output end to rotate. The connecting belt drives the gear to rotate through the second pulley. Because the two gears mesh with each other, the connecting belt can drive another first pulley to rotate relative to the first pulley fixedly connected to the output end of the second motor. This allows the two rotating rollers to rotate relative to each other inside the storage box.

[0013] Preferably, the limiting device includes a rubber belt, which is slidably inserted through one side of the feed pipe, and rubber blocks are uniformly fixedly connected to the rubber belt near the inner wall of the feed pipe.

[0014] The effect achieved by the above components is as follows: When using the limiting device, one end of the water pipe outlet is inserted into the inner wall of the rubber belt set inside the feed pipe, so that the rubber block on the inner wall of the rubber belt is pressed against the surface of the water pipe. This increases the friction between the water pipe and the rubber belt to a certain extent, so that the water pipe can be effectively restricted to one end of the feed pipe, thus avoiding the need for manual holding of the water pipe when water is being fed in.

[0015] Preferably, a support plate is fixedly connected to the inner wall of the end of the rubber belt away from the feed pipe, and a second damping rod is fixedly connected to one side of the support plate. The end of the second damping rod near the rubber belt is fixedly connected to one side of the feed pipe. A second spring is sleeved on the surface of the second damping rod. One end of the second spring is fixedly connected to one side of the support plate, and the end of the second spring near the second damping rod is fixedly connected to one side of the feed pipe.

[0016] The effect achieved by the above components is that the rubber belt is squeezed away from the feed pipe by the second spring, thereby causing the rubber blocks evenly arranged on the inner wall of the rubber belt to be squeezed onto the surface of the water pipe.

[0017] Preferably, a support block is fixedly connected to the side of the support plate away from the rubber belt, a bolt is threaded through the top of the support block, a rubber plate is provided at the bottom of the bolt, and the bottom of the rubber plate is fixedly connected to the bottom of the main body of the stirring device.

[0018] The effect achieved by the above components is that when the rubber block is pressed against the surface of the water pipe, the bolt is manually controlled to rotate, and the bolt is pressed against the top of the rubber plate, which can restrict the rubber block to the surface of the water pipe.

[0019] Preferably, a circular plate is rotatably fitted onto the bottom of the bolt, and protrusions are uniformly fixedly connected to the bottom of the circular plate.

[0020] The effect achieved by the above components is that when the bottom of the bolt is close to the rubber plate, the protrusion fixedly connected to the bottom of the circular plate presses against the top of the rubber plate, which causes the rubber to be squeezed and deformed, thereby allowing the bolt to be properly positioned on one side of the rubber plate.

[0021] In this invention, by setting up a feeding device, when using the feeding device, stones are placed inside the storage box, and other raw materials are placed inside the main body of the mixing device. Then, the first motor is started, which drives the mixing rod to rotate. When the mixing rod squeezes the rubber ball, the first spring is stretched, which causes the baffle to slide on the inner wall of the chute, thus exposing the discharge hole. When the mixing rod moves away from the rubber ball, the first spring returns to its original state, which causes the baffle to return to its original position. In this way, stones can be added slowly as the mixing rod stirs, which to a certain extent avoids the stones from piling up. Attached Figure Description

[0027] Example 1, as Figure 1-4As shown, a clog-resistant concrete mixing device is provided. A first motor 2 is fixedly connected to the top of the mixing device body 1, and a mixing rod 3 is fixedly connected to the output end of the first motor 2. A discharge pipe 4 is provided at the bottom of the mixing device body 1, and a solenoid valve 5 is provided inside the discharge pipe 4. A feed pipe 6 is provided at the top of the mixing device body 1, and a feeding device 7 is provided at the top of the mixing device body 1. A limit device 8 is provided on one side of the feed pipe 6. When using the mixing device, lime powder, stones and water are placed into the mixing device by hand, and then the first motor 2 drives the mixing rod 3 to rotate. The mixing rod 3 mixes the raw materials evenly, which facilitates the formation of concrete.

[0028] Reference Figure 2 and Figure 3The feeding device 7 includes a storage tank 701, which is fixedly connected to the top of the mixing device body 1. A discharge hole 703 is provided at the bottom of the storage tank 701. A groove 704 is provided on the inner wall of the discharge hole 703. A baffle 705 is slidably connected to the inner wall of the groove 704. A connecting plate 706 is fixedly connected to the end of the baffle 705 away from the discharge hole 703. A rubber ball 707 is fixedly connected to the bottom of the connecting plate 706. A first damping rod 708 is fixedly connected to the side of the connecting plate 706 near the baffle 705. The end of the first damping rod 708 away from the connecting plate 706 is fixedly connected to the side of the discharge hole 703. A first spring 709 is sleeved on the surface of the first damping rod 708. One end of the first spring 709 is connected to the discharge hole 703. One side is fixedly connected, and the end of the first spring 709 near the first damping rod 708 is fixedly connected to one side of the connecting plate 706. When using the feeding device 7, stones are placed inside the storage box 701, and other raw materials are placed inside the mixing device body 1. Then, the first motor 2 is started, which drives the mixing rod 3 to rotate. When the mixing rod 3 squeezes the rubber ball 707, the first spring 709 is stretched, which causes the baffle 705 to slide on the inner wall of the chute 704, thus exposing the discharge hole 703. When the mixing rod 3 moves away from the rubber ball 707, the first spring 709 returns to its original shape, which causes the baffle 705 to return to its original position. This allows stones to be added slowly as the mixing rod 3 stirs. To prevent stones from accumulating, the inner wall of the storage box 701 has an inclined surface 702. A rotating roller 711 is evenly inserted into the inner wall of the storage box 701, positioned at the top of the inclined surface 702. Because the inner wall of the storage box 701 has symmetrical inclined surfaces 702, controlling the rotation of the rotating roller 711 helps prevent stones from getting stuck inside the storage box 701. A protective sleeve 710 is fixedly connected to one side of the discharge hole 703. The protective sleeve 710 is fitted onto the surface of the first damping rod 708 and the first spring 709. The end of the protective sleeve 710 away from the discharge hole 703 is slidably inserted into one side of the connecting plate 706. The function of the protective sleeve 710 is to prevent concrete raw materials from contacting the first damping rod. 708 and the first spring 709 are arranged to prevent the raw materials from affecting the stretching and contraction of the first spring 709 to a certain extent. A connecting frame 713 is fixedly connected to one side of the storage box 701, and a second motor 714 is fixedly connected to one side of the connecting frame 713. A first pulley 712 is fixedly connected to the output end of the second motor 714. One side of the first pulley 712 is fixedly connected to the end of the rotating roller 711 away from the storage box 701. Gears 715 are evenly inserted on one side of the storage box 701, and two gears 715 mesh with each other. A second pulley 716 is fixedly attached to the side of the gears 715 away from the storage box 701. A connecting belt 717 is fitted on the surface of the first pulley 712 and the second pulley 716. The second motor 714 is started.The second motor 714 drives the first pulley 712 and the rotating roller 711 fixedly connected to the output end to rotate. The connecting belt 717 drives the second pulley 716 to rotate the gear 715. Because the two gears 715 mesh with each other, the connecting belt 717 can then drive another first pulley 712, which is fixedly connected to the output end of the second motor 714, to rotate relative to it. This allows the two rotating rollers 711 to rotate relative to each other inside the storage box 701.

[0029] Reference Figure 4 The limiting device 8 includes a rubber belt 801, which is slidably inserted into one side of the feed pipe 6. Rubber blocks 802 are evenly fixedly connected to the inner wall of the rubber belt 801 near the feed pipe 6. When using the limiting device 8, one end of the water pipe outlet is inserted into the inner wall of the rubber belt 801 located inside the feed pipe 6, causing the rubber blocks 802 on the inner wall of the rubber belt 801 to press against the surface of the water pipe. This increases the friction between the water pipe and the rubber belt 801 to a certain extent, effectively limiting the water pipe to one end of the feed pipe 6. To avoid the need for manual hand-holding of the water hose during water intake, a support plate 805 is fixedly connected to the inner wall of the end of the rubber belt 801 furthest from the feed pipe 6. A second damping rod 803 is fixedly connected to one side of the support plate 805. The end of the second damping rod 803 near the rubber belt 801 is fixedly connected to one side of the feed pipe 6. A second spring 804 is sleeved on the surface of the second damping rod 803. One end of the second spring 804 is fixedly connected to one side of the support plate 805, and the end of the second spring 804 near the second damping rod 803 is fixedly connected to one side of the feed pipe 6. A fixed connection is established. A second spring 804 presses the rubber belt 801 away from the feed pipe 6, causing the rubber blocks 802 evenly distributed on the inner wall of the rubber belt 801 to press against the surface of the water pipe. A support block 806 is fixedly connected to the side of the support plate 805 away from the rubber belt 801. A bolt 807 is threaded through the top of the support block 806, and a rubber plate 808 is provided at the bottom of the bolt 807. The bottom of the rubber plate 808 is fixedly connected to the bottom of the mixing device body 1. When the rubber blocks 802 press against the surface of the water pipe, manual... The bolt 807 is rotated and pressed against the top of the rubber plate 808, thus restricting the rubber block 802 to the surface of the water pipe. A circular plate 809 is rotatably fitted onto the bottom of the bolt 807. Protrusions 810 are evenly fixedly connected to the bottom of the circular plate 809. When the bottom of the bolt 807 approaches the rubber plate 808, the protrusions 810 fixedly connected to the bottom of the circular plate 809 press against the top of the rubber plate 808, thus deforming the rubber and allowing the bolt 807 to be properly positioned on one side of the rubber plate 808.

[0030] Working principle: When using the mixing device, lime powder, stones, and water are manually placed inside. The first motor 2 then drives the mixing rod 3 to rotate, mixing the raw materials evenly to facilitate concrete formation. When using the feeding device 7, stones are placed inside the storage tank 701, and other raw materials are placed inside the main body 1 of the mixing device. The first motor 2 is then started, driving the mixing rod 3 to rotate. When the mixing rod 3 squeezes the rubber ball 707, the first spring 709 is stretched, causing the baffle 705 to slide against the inner wall of the chute 704, thus exposing the discharge hole 703. When the mixing rod 3 moves away from the rubber ball... When ball 707 is stirred, the first spring 709 returns to its original state, causing the baffle 705 to return to its original position. This allows for the slow addition of pebbles as the stirring rod 3 stirs, preventing pebbles from piling up to some extent. Because the inner wall of the storage tank 701 has symmetrical inclined surfaces 702, the second motor 714 is started. The second motor 714 drives the first pulley 712 and the rotating roller 711 fixedly connected to the output end to rotate. Through the connecting belt 717, the second pulley 716 drives the gear 715 to rotate. Because the two gears 715 mesh, another connecting belt 717 can drive another first pulley 712 and the second motor 714 to output. The first pulley 712, which is fixedly connected to the end, rotates relative to each other, allowing the two rotating rollers 711 to rotate relative to each other inside the storage box 701. This can, to some extent, prevent stones from getting stuck inside the storage box 701. The protective sleeve 710 prevents concrete raw materials from contacting the first damping rod 708 and the first spring 709, thus preventing the raw materials from affecting the tension and contraction of the first spring 709. When using the limiting device 8, one end of the water pipe outlet is inserted into the inner wall of the rubber belt 801 located inside the feed pipe 6. The second spring 804 squeezes the rubber belt 801 away from the feed pipe 6, thereby causing the inner wall of the rubber belt 801 to... The evenly spaced rubber blocks 802 are pressed against the surface of the water pipe, which increases the friction between the water pipe and the rubber strip 801 to a certain extent. When the rubber blocks 802 are pressed against the surface of the water pipe, the bolt 807 is manually rotated. When the bottom of the bolt 807 is close to the rubber plate 808, the protrusion 810 fixedly connected to the bottom of the round plate 809 is pressed against the top of the rubber plate 808, which causes the rubber to be deformed. This allows the bolt 807 to be properly positioned on one side of the rubber plate 808, thus restricting the rubber blocks 802 to the surface of the water pipe and effectively confining the water pipe to one end of the feed pipe 6. This avoids the need for manual handling of the water pipe during water intake.

[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
