Description

Technical Field

[0001] The invention relates to the technical field of double-blade cutting equipment, in particular to a double-blade cutting pump with a crushing mechanism. Background Art

[0002] With the development of society, the urban population is increasing, and the number of factories and enterprises is also increasing. The amount of sewage and wastewater generated will also increase. It is inevitable that the wastewater will contain some larger domestic garbage. However, the cutting effect of some cutting pumps currently on the market is not ideal, especially when cutting some softer debris, clogging will occur, which cannot meet the requirements.

[0003] A cutting pump is disclosed in the announcement number CN108071610A, including a base, a pump body is installed on the upper end of the base, the pump body and the base are connected by large screws, an impeller is installed inside the pump body, a reamer is installed at the lower end of the impeller, the reamer is fixed to the shaft by a nut, a gasket is installed between the nut and the reamer, a connecting seat is installed on the upper end of the pump body, a motor component is installed on the upper end of the connecting seat, and the pump body and the connecting seat are connected by large screws. The present invention installs a reamer at the lower end of the impeller, so that the debris in the sewage can be shredded when entering the pump body, and the rotation of the reamer helps the sewage to be removed. The entry of water increases the efficiency of the water pump. By setting the cutter head to be distributed in an upper and lower manner, the debris can be cut multiple times. It is stable and reliable, and has a simple structure, convenient operation, and is economical and practical. However, there are serious shortcomings: the blade is easily deformed by external impact during work, which can easily affect the cutting effect of the equipment on softer debris. When a single knife cuts softer debris, the softer debris has fewer force points and is prone to not being cut off. In addition, soft objects such as wires are easily entangled on the rotating shaft, which increases the workload of the rotating shaft, while reducing the working efficiency of the equipment and affecting the service life of the equipment.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0005] The purpose of the present invention is to make the fixed blades on both sides cut the wires wound around the outside of the driving shaft to avoid the wires winding around the driving shaft and increasing the workload of the driving motor, thereby achieving the effect of automatically cleaning the surface of the driving shaft and avoiding the high-load operation of the driving motor to reduce its own service life, solving the existing problems of wire winding on the surface of the driving shaft and reducing the service life of the driving motor. In addition, the gap between the auxiliary cutter disc and the outer blade is automatically adjusted to prevent the outer blade from deforming. The different installation angles of the inner blade and the outer blade form a staggered trend. The double blade action facilitates the thorough crushing of debris, so that the debris is crushed under the dual action of the outer blade and the inner blade, thereby improving the crushing effect of the equipment and preventing the equipment from being blocked, solving the existing problem of poor crushing effect of the equipment.

[0013] Preferably, the outer blade and the inner blade rotate in the same direction, and are the same size as each other. The limit pin is located inside the limit spring, and the limit pin is slidably connected to the positioning plate.

[0014] Preferably, the method for using the double-blade cutting pump with a pulverizing mechanism comprises the following steps:

[0015] Step 1: Turn on the external control switch to start the equipment working, so that the driving motor drives the driving shaft to rotate, and during the rotation of the driving shaft, the driving shaft drives the external impeller to rotate, and then starts the sewage discharge work;

[0016] Step 2: When the driving shaft is rotating, the driving shaft drives the external bevel gear to rotate, and the bevel gear drives the driven wheels on both sides to rotate through the transmission between the gears, so that the driven wheels drive the positioning pins on the front surface to move inside the driving slide rail, so that the positioning pins push the guide push rod on the driving slide rail to first rise and then fall inside the limit slide rail;

[0017] Step 3: When the driving slide rail drives the guide push rod to rise inside the limit slide rail, that is, the guide push rod moves to the outside of the sealing box, so that the guide push rod drives the fixed blade to slide outside the driving shaft, so that the fixed blades on both sides cut the wire wound around the outside of the driving shaft, so as to prevent the wire from winding around the driving shaft and increasing the workload of the driving motor;

[0019] Step 4: while the driving shaft rotates, the outer blade in front of the auxiliary blade disc is driven to rotate. When the outer blade contacts a hard object, the outer blade drives the positioning disc to slide outside the limit latch, and at the same time, the limit spring is elastically deformed, so that the outer blade approaches the auxiliary blade disc, that is, the gap between the auxiliary blade disc and the outer blade becomes smaller, so that the auxiliary blade disc plays an auxiliary support to prevent the outer blade from deforming, thereby improving the crushing effect of the outer blade;

[0020] Step 5: The driving shaft drives the inner blade on the rear side of the auxiliary cutter disc to move synchronously, so that the soft debris is crushed under the dual action of the outer blade and the inner blade, which can not only improve the crushing effect of the equipment, but also prevent the outer blade from deforming, and finally discharge the sewage from the inside of the outlet pipe.

[0021] Beneficial effects of the present invention:

[0022] (1) The guide push rod drives the fixed blade to slide outside the driving shaft, so that the fixed blades on both sides cut the wires wrapped around the outside of the driving shaft, thereby preventing the wires from wrapping around the driving shaft and increasing the workload of the driving motor. This can achieve the effect of automatically cleaning the surface of the driving shaft and preventing the driving motor from running at high load and reducing its service life, thereby solving the existing problem of wire wrapping on the driving shaft surface and reducing the service life of the driving motor, thereby improving the working efficiency of the equipment;

[0023] (2) When the outer blade contacts a hard object during rotation, the outer blade drives the positioning disc to slide outside the limit pin, thereby reducing the gap between the auxiliary blade disc and the outer blade, so that the auxiliary blade disc plays an auxiliary support role to prevent the outer blade from being deformed, thereby increasing the service life of the outer blade;

[0024] (3) The inner blade and the outer blade are installed at different angles to form a staggered position. The double blades facilitate the complete crushing of debris and prevent the debris from affecting the impeller. Therefore, the debris is crushed under the dual action of the outer blade and the inner blade, which can not only improve the crushing effect of the equipment, but also prevent the equipment from being blocked, thereby solving the problem of poor crushing effect of the existing equipment.

[0036] Embodiment 1:

[0037] See also Figure 1-8As shown, the present invention is a double-blade cutting pump with a crushing mechanism, including a pump base 1, which is fixedly connected to a pump body protection box 2 through a support column and a support plate, and the pump body protection box 2 is a hollow design, which is convenient for sewage to enter the interior of the equipment from the lower surface of the pump body protection box 2 and then be discharged. A fixing plate 3 is fixedly connected to one side of the pump body protection box 2, and the interior of the fixing plate 3 is a cavity, which is convenient for sewage to enter. An outlet pipe 4 is inserted into the interior of the upper surface of the fixing plate 3. Before working, a sewage hose is sleeved on the outside of the outlet pipe 4 to facilitate the discharge of sewage. A drive motor 5 is fixedly connected to the center of the upper surface of the pump body protection box 2, and the drive motor 5 serves as the whole equipment. The driving device is connected to an external power source through a power line 7 on its upper surface. In order to facilitate the transportation of the driving motor 5, a handle 6 is fixedly connected to the upper surface of the driving motor 5. A driving shaft 8 is inserted into the interior of the pump body protection box 2, and one end of the driving shaft 8 is rotatably connected to the driving motor 5. The inner wall of the pump body protection box 2 is symmetrically fixedly connected with a support rod 10. After the device is placed, the external power supply is turned on to start the device to work, and then the driving motor 5 drives the driving shaft 8 to rotate. In the process of the driving shaft 8 rotating, the driving shaft 8 drives the external impeller 9 to start working, and then the device absorbs and discharges sewage, thereby achieving the sewage discharge effect;

[0038] In addition, when the driving shaft 8 rotates, the driving shaft 8 drives the external bevel gear 114 to rotate, and the bevel gear 114 is located inside the anti-winding mechanism 11. Through the transmission between the gears, the bevel gear 114 drives the two driven wheels 113 to rotate. The rear end of the driven wheel 113 is meshed and connected with the bevel gear 114, and the bevel gear 114 is located outside the driving shaft 8. The front surface of the driven wheel 113 is fixedly connected with a positioning pin 115, and the outside of the positioning pin 115 is sleeved with a driving slide rail 116, and a positioning pin 115 is provided inside the driving slide rail 116. The pins 115 match the slide grooves with each other, the upper surface of the driving slide rail 116 is fixedly connected with a guide push rod 117, and the guide push rod 117 runs through the interior of the sealing box 111, and the outer sleeve of the guide push rod 117 is connected with a limit slide rail 118, and the limit slide rail 118 plays the role of limit guide, ensuring that the moving direction of the guide push rod 117 remains unchanged, and the rear surface of the limit slide rail 118 is fixedly connected with an L-shaped fixing rod 119, and the end of the L-shaped fixing rod 119 away from the limit slide rail 118 is fixedly connected to the outer surface of the positioning shaft 112, when the bevel gear 114 drives the driven wheel 113 When rotating, the guide push rod 117 on the driving slide rail 116 is first driven to slide toward the outside of the sealing box 111, so that the guide push rod 117 drives the fixed blade 110 to slide outside the driving shaft 8. When the fixed blade 110 moves to the maximum distance, the fixed blade 110 and the positioning plate 17 are not in contact, so that the fixed blades 110 on both sides cut the wires wound around the outside of the driving shaft 8, avoiding the winding of the wires around the driving shaft 8 and increasing the workload of the driving motor 5, and at the same time facilitating the automatic cleaning of the windings on the surface of the driving shaft 8;

[0039] When the driving slide rail 116 drives the guide push rod 117 to move downward inside the limiting slide rail 118, the guide push rod 117 drives the fixed blade 110 to slide outside the driving shaft 8 toward the inner direction of the sealing box 111, so that the guide push rod 117 re-enters the interior of the sealing box 111, and at the same time, the guide push rod 117 drives the fixed blade 110 to move on the outer surface of the driving shaft 8 again, so that the fixed blade 110 shears the surface line again to ensure the shearing effect. At the same time, when the fixed blade 110 moves to the starting position, at this time, the driving slide rail 116 drives the guide push rod 117 to start the next shearing work, thereby achieving the effect of reciprocating shearing and improving the working efficiency of the equipment. Therefore, it can achieve the effect of automatically cleaning the surface of the driving shaft 8, and can avoid the high-load operation of the driving motor 5 to reduce its own service life, solve the problem of the existing driving shaft 8 surface line winding and reducing the service life of the driving motor 5, thereby improving the working efficiency of the equipment.

[0040] Embodiment 2: A crushing mechanism 12 is arranged inside the pump body protection box 2, and the crushing mechanism 12 includes an auxiliary cutter disc 13, the inner wall of the auxiliary cutter disc 13 is symmetrically fixedly connected with a cylindrical rod 14, and one end of the cylindrical rod 14 away from the auxiliary cutter disc 13 is fixedly connected with a fixed sleeve 15, and the fixed sleeve 15 is located outside the driving shaft 8, and the interior of the fixed sleeve 15 is rotatably connected with a positioning sleeve 23, and the positioning sleeve 23 and the fixed sleeve 15 are fixedly connected. The positioning sleeve 23 is connected in rotation, and the positioning sleeve 23 is fixedly connected to the driving shaft 8, so that the driving shaft 8 drives the positioning sleeve 23 to rotate while rotating, and the cylindrical rod 14 plays the role of an auxiliary support, so that softer debris has multiple support points, thereby facilitating the crushing of softer debris, and the water inlet formed between the fixed sleeve 15 and the auxiliary cutter disc 13 is convenient for water to enter. A limiting spring 16 is fixedly connected to one side of the positioning sleeve 23, and a positioning plate 17 is fixedly connected to the end of the limiting spring 16 away from the positioning sleeve 23, and an outer blade 18 is fixedly connected to the outer surface of the positioning plate 17. When the equipment starts working, the driving motor 5 drives the driving shaft 8 to rotate, and then the driving shaft 8 drives the external positioning plate 17 to rotate through the limiting latch 21, and then the positioning plate 17 drives the external outer blade 18 to rotate, so that the outer blade 18 and the auxiliary cutter disc 13 cooperate with each other to crush the softer objects, thereby improving the crushing effect of the equipment;

[0041] When the outer blade 18 contacts a hard object during rotation, the outer blade 18 drives the positioning plate 17 to slide outside the limiting latch 21, and at the same time, the limiting spring 16 is elastically deformed, so that the outer blade 18 slides in the direction of the auxiliary blade disc 13, so that the outer blade 18 is close to the auxiliary blade disc 13, that is, the gap between the auxiliary blade disc 13 and the outer blade 18 becomes smaller, so that the auxiliary blade disc 13 plays an auxiliary support to prevent the outer blade 18 from being deformed, thereby improving the crushing effect of the outer blade 18 and protecting the outer blade 18. A positioning bolt 22 is arranged on one side of the positioning plate 17, and the positioning bolt 22 is connected to the driving shaft 8 by threaded rotation, so that the positioning bolt 22 contacts the left side of the limiting latch 21 after being rotated and fixed, and then the positioning plate 17 is limited to ensure the moving direction of the positioning plate 17 and protect the positioning plate 17 at the same time.

[0042] A fixed blade holder 19 is provided on the side of the auxiliary cutter disc 13 away from the positioning disc 17. The fixed blade holder 19 is sleeved on the outside of the driving shaft 8 and is fixedly connected to the driving shaft 8. An inner blade 20 is fixedly connected to the outer surface of the fixed blade holder 19, and the inner blade 20 is located on the right side of the auxiliary cutter disc 13. The driving shaft 8 drives the inner blade 20 on the rear side of the auxiliary cutter disc 13 to move synchronously. The interaction between the inner blade 20 and the auxiliary cutter disc 13 is used to crush debris. The inner blade 20 and the outer blade 18 are installed at different angles to form a staggered trend, which is convenient for thoroughly crushing debris and avoiding the debris from affecting the impeller 9. Therefore, the debris is crushed under the dual action of the outer blade 18 and the inner blade 20, thereby achieving the effect of not only improving the crushing effect of the equipment but also preventing the outer blade 18 from deforming.

[0043] The working principle of the present invention is as follows: after placing the device, turn on the external power supply to start the device working, and then the driving motor 5 drives the driving shaft 8 to rotate, so that the driving shaft 8 drives the external bevel gear 114 to rotate, and through the transmission between the gears, the bevel gear 114 drives the driven wheel 113 to rotate, and then drives the guide push rod 117 on the driving slide rail 116 to slide to the outside of the sealing box 111, so that the guide push rod 117 drives the fixed blade 110 to slide on the outside of the driving shaft 8, so that the fixed blades 110 on both sides cut the wire wound on the outside of the driving shaft 8, so as to avoid the wire winding around the driving shaft 8 and increase the workload of the driving motor 5, and at the same time facilitate the device to automatically clean the winding on the surface of the driving shaft 8, so that the guide push rod 117 drives the fixed blade The blade 110 slides from the outside of the driving shaft 8 to the inside of the sealing box 111, so that the guide push rod 117 re-enters the inside of the sealing box 111. At the same time, when the fixed blade 110 moves to the starting position, the driving slide rail 116 drives the guide push rod 117 to start the next shearing work, thereby achieving the effect of automatically cleaning the surface of the driving shaft 8 and avoiding the driving motor 5 from running at high load and reducing its own service life, thereby solving the problem of wire winding on the surface of the driving shaft 8 and reducing the service life of the driving motor 5, thereby improving the working efficiency of the equipment.

[0044] The outer positioning disc 17 is driven to rotate by the limit pin 21, and then the positioning disc 17 drives the outer blade 18 to rotate accordingly, so that the outer blade 18 and the auxiliary blade disc 13 cooperate with each other to crush the softer objects, thereby improving the crushing effect of the equipment. When the outer blade 18 contacts the hard object during the rotation process, the outer blade 18 drives the positioning disc 17 to slide outside the limit pin 21, so that the gap between the auxiliary blade disc 13 and the outer blade 18 becomes smaller, so that the auxiliary blade disc 13 plays an auxiliary support to prevent the outer blade 18 from being crushed. The auxiliary cutter disc 13 is deformed, and the driving shaft 8 drives the inner blade 20 on the rear side of the auxiliary cutter disc 13 to move synchronously. The inner blade 20 and the auxiliary cutter disc 13 are used to crush the debris. The inner blade 20 and the outer blade 18 are installed at different angles to form a staggered position, which is convenient for crushing the debris thoroughly and avoiding the debris from affecting the impeller 9. Therefore, the debris is crushed under the dual action of the outer blade 18 and the inner blade 20, thereby achieving the effect of improving the crushing effect of the equipment and preventing the outer blade 18 from deforming.
