Description

Technical Field

[0001] This utility model relates to the field of mortar lifting technology, and in particular to a mortar lifting machine. Background Technology

[0002] A mortar hoist is a type of mechanical equipment used in construction for vertically transporting mortar. From the outside, it looks a bit like a small elevator. Its main components include a sturdy frame made of metal, which supports the entire structure of the hoist and ensures its stability.

[0003] A search revealed Chinese Patent Publication No. CN209192935U, which discloses a mortar elevator, relating to the field of lifting equipment technology. It includes a support base, a feeding device rotatably connected to the support base, and an adjusting device that drives the feeding device to rotate. The feeding device includes a housing and a conveyor belt disposed inside the housing. The adjusting device includes a fixing block fixed to the support base and an adjusting assembly. A rotating shaft rotatably connected to the fixing block is fixed to the side of the housing near the support base. The adjusting assembly includes a worm gear rotating coaxially with the rotating shaft and a worm meshing with the worm gear. Rotating the worm gear drives the worm gear to rotate, thereby driving the housing to rotate, changing the angle between the housing and the support base, changing the distance from the top of the conveyor belt to the support base, and thus changing the height of the elevator's discharge end. The use of a worm gear allows for more precise adjustment of the housing's rotation angle, thereby more precisely adjusting the height of the conveyor belt's discharge end. Existing mortar elevators transport mortar upwards via a conveyor belt, but this method results in mortar adhering to the conveyor belt over time, affecting equipment operation and making cleaning difficult. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a mortar hoist, which aims to improve the existing conveying method. During long-term use, mortar will adhere to the conveyor belt, which will not only affect the operation of the equipment, but also cause problems that are difficult to clean.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mortar lifting machine, comprising a fixed frame, characterized in that: a motor is fixedly connected to the rear end of the inner wall of the fixed frame; a connecting rod is rotatably connected to the upper and lower ends of the rear side of the motor; a drive sprocket is fixedly connected to the left and right ends of the outer wall of the lower connecting rod; a driven sprocket is fixedly connected to the left and right ends of the outer wall of the upper connecting rod; the two drive sprockets are respectively connected to the corresponding driven sprockets via corresponding chains; multiple lifting blocks are fixedly connected at equal intervals on adjacent sides of the two chains; a conveying box is slidably connected to the outer side of the lower lifting block; and a circulating transmission mechanism is installed on the top of the fixed frame for circulating transmission of the conveying box.

[0006] Through the above technical solution: the power provided by motor one drives the connecting rod below to start rotating. As the connecting rod below starts rotating, the drive sprockets fixed on both sides of it will also rotate together. At the same time as the drive sprockets rotate, they will drive the corresponding driven sprockets fixed on both sides of the connecting rod above to rotate synchronously through two chains. As the two chains rotate, multiple lifting blocks fixed on their adjacent sides will also be driven to rotate. At this time, the conveying box containing mortar is hung on one of the pairs of lifting blocks through the handles on both sides, thereby moving the conveying box containing mortar upward.

[0007] As a further description of the above technical solution:

[0008] The circulating transmission mechanism includes rotating rods, with the left and right ends of multiple rotating rods rotatably connected to the upper inner side of a fixed frame. A motor is fixedly connected to an adjacent end of each of the front rotating rods. A power gear is fixedly connected to an adjacent side of the outer wall of each of the multiple rotating rods. Multiple fixed rods are fixedly connected at equal intervals to the upper inner wall of the fixed frame. An auxiliary wheel is rotatably connected to an adjacent end of each of the multiple fixed rods. A transmission belt is provided on the outer side of each of the multiple rotating rods.

[0009] The above technical solution works as follows: the power provided by motor 2 drives the rotating rod connected to it to rotate. When the rotating rod rotates, the power gear fixed on it will be driven to rotate synchronously. At the same time as the power gear rotates, it will mesh with the adjacent auxiliary wheel fixed by the fixing rod, thereby driving the adjacent auxiliary wheel to rotate. The power gear then drives the next power gear to rotate, and so on, driving all the rotating rods and power gears to rotate. The rotation of multiple rotating rods drives the rotation of the transmission belt.

[0010] As a further description of the above technical solution:

[0011] A stabilizing frame is fixedly connected to the bottom of the motor, and screws are threaded to the left and right sides, front and rear ends of the stabilizing frame.

[0012] The above technical solution improves the stability of motor one by fixing the motor with screws and using a stabilizer.

[0013] As a further description of the above technical solution:

[0014] Each of the multiple rotating rods has a rubber sleeve fixedly connected to its outer wall, and each of the multiple rubber sleeves has anti-slip texture on its outer wall.

[0015] The above technical solution improves the grip of the rotating rod by using a rubber sleeve fixed to the outside of the rotating rod with anti-slip grooves.

[0016] As a further description of the above technical solution:

[0017] Multiple limiting strips are equidistantly installed on the top of the conveyor belt, and thumbtacks are fixedly connected to the left and right sides of each of the multiple limiting strips.

[0018] The above technical solution allows the limiting strip, which is fixed by thumbtacks, to better drive the conveyor belt to move the conveyor box.

[0019] As a further description of the above technical solution:

[0020] The rear outer wall of the fixing frame is threaded with hinges on both the left and right ends, and the rear sides of the multiple hinges are threaded with baffles.

[0021] The above technical solution involves mounting the baffle onto the frame via a hinge to provide protection for the chain.

[0022] As a further description of the above technical solution:

[0023] Both hinges have snap fasteners fixedly connected to their outer rear ends, and both snap fasteners have pins slidably connected to their inner sides.

[0024] The above technical solution allows the buckle and pin fixed to the baffle to fix the position of the baffle.

[0025] As a further description of the above technical solution:

[0026] Multiple support frames are fixedly connected at equal intervals on the lower inner side of the fixed frame, and a base plate is fixedly connected to the bottom of the fixed frame.

[0027] The above technical solution involves a support frame to enhance the stability of the fixed frame, while the base plate fixed under the fixed frame provides support.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the motor drives two chains to rotate synchronously through the cooperation of the connecting rod, the driving sprocket and the driven sprocket, thereby driving multiple lifting blocks to rotate and lift the conveying box containing mortar upward. After using the mortar hoist, only the conveying box needs to be cleaned, thus achieving the effect of preventing mortar from adhering to the mortar hoist.

[0030] 2. In this utility model, the second motor drives all the rotating rods to rotate synchronously through the cooperation of the power gear and the auxiliary wheel. The rotation of multiple rotating rods drives the rotation of the conveyor belt, and then the conveyor box is placed on the conveyor belt. The conveyor belt sends it to the rising lifting block, and then the empty conveyor box that has been lowered by the lifting block is brought back, thus achieving the effect of cyclic conveying of the conveyor box.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 3This utility model provides an embodiment of a mortar hoist, including a fixed frame 1. A motor 3 is fixedly connected to the rear end of the inner wall of the fixed frame 1. A connecting rod 4 is rotatably connected to the upper and lower ends of the rear side of the motor 3. A drive sprocket 5 is fixedly connected to the left and right ends of the outer wall of the lower connecting rod 4. The motor 3 drives the drive sprocket 5 to rotate through the connecting rod 4. A driven sprocket 6 is fixedly connected to the left and right ends of the outer wall of the upper connecting rod 4. The two drive sprockets 5 are respectively connected to the corresponding driven sprockets 6 through corresponding chains 7. The driven sprocket 5 drives the driven sprocket 6 to rotate via the chain 7. Multiple lifting blocks 8 are fixedly connected at equal intervals on the adjacent sides of the two chains 7. A conveyor box 9 is slidably connected to the outer side of the lower lifting block 8. The chain 7 drives the conveyor box 9 to move upward via the lifting block 8. A circulating transmission mechanism 2 is installed on the top of the fixed frame 1. The circulating transmission mechanism 2 is used to circulate and transmit the conveyor box 9. A stabilizing frame 10 is fixedly connected to the bottom of the motor 3. Screws 11 are threadedly connected to the front and rear ends of the left and right sides of the stabilizing frame 10. The screws 11 are used to fix the stabilizing frame 10.

[0040] Specifically, the power provided by motor 3 drives the lower connecting rod 4 to rotate. As the lower connecting rod 4 rotates, the drive sprockets 5 fixed on both sides of it will also rotate. At the same time as the drive sprockets 5 rotate, they will drive the corresponding driven sprockets 6 fixed on both sides of the upper connecting rod 4 to rotate synchronously through two chains 7. As the two chains 7 rotate, multiple lifting blocks 8 fixed on their adjacent sides will also be driven to rotate. At this time, the mortar conveying box 9 is hung on one of the pair of lifting blocks 8 through the handles on both sides, thus moving the mortar conveying box 9 upward. After using the mortar hoist, only the conveying box 9 needs to be cleaned. The stability of motor 3 can be improved by fixing the drive frame 10 with screws 11.

[0041] Reference Figure 4 and Figure 5 The circulating transmission mechanism 2 includes rotating rods 201. The left and right ends of multiple rotating rods 201 are rotatably connected to the upper inner side of the fixed frame 1. A second motor 202 is fixedly connected to an adjacent end of each front rotating rod 201. A power gear 203 is fixedly connected to an adjacent side of the outer wall of each of the multiple rotating rods 201. The second motor 202 drives the power gear 203 to rotate via the rotating rods 201. Multiple fixed rods 204 are equidistantly fixed to the upper inner wall of the fixed frame 1. The adjacent ends of the multiple fixed rods 204 are rotatably connected to... An auxiliary wheel 205 is attached, and a fixing rod 204 is used to fix the auxiliary wheel 205. A conveyor belt 206 is provided on the outer side of multiple rotating rods 201. A rubber sleeve 12 is fixedly connected to the outer wall of multiple rotating rods 201. Anti-slip texture 13 is provided on the outer wall of multiple rubber sleeves 12. The anti-slip texture 13 is used to improve the anti-slip performance of the rubber sleeves 12. Multiple limiting strips 14 are installed at equal intervals on the top of the conveyor belt 206. Thumbtacks 15 are fixedly connected to the left and right sides of multiple limiting strips 14. The thumbtacks 15 are used to fix the limiting strips 14.

[0042] Specifically, the power provided by motor 202 drives the rotating rod 201 connected to it to rotate. When the rotating rod 201 rotates, the power gear 203 fixed on it will be driven to rotate synchronously. As the power gear 203 rotates, it will mesh with the adjacent auxiliary wheel 205 fixed by the fixing rod 204, thereby driving the adjacent auxiliary wheel 205 to rotate. The power gear 203 then drives the next power gear 203 to rotate, and so on, driving all the rotating rods 201 and power gears 203 to rotate. The rotation of multiple rotating rods 201 drives the rotation of the conveyor belt 206. Then, the conveyor box 9 is placed on the conveyor belt 206 and sent to the rising lifting block 8. The empty conveyor box 9 is then brought back after being lowered by the lifting block 8. The rubber sleeve 12 fixed to the outside of the rotating rod 201 enhances the grip of the rotating rod 201 through the anti-slip texture 13. The limiting strip 14 fixed by the thumbtack 15 enables the conveyor belt 206 to better drive the movement of the conveyor box 9.

[0043] Reference Figure 1 and Figure 2 The left and right ends of the rear outer wall of the fixed frame 1 are threaded with hinges 16. The rear sides of multiple hinges 16 are threaded with baffles 17. The hinges 16 are used to install the baffles 17. The rear ends of the outer walls of two hinges 16 are fixedly connected with buckles 18. The inner sides of two buckles 18 are slidably connected with pins 19. The pins 19 and buckles 18 are used to fix the baffles 17. Multiple support frames 20 are fixedly connected at equal intervals in the lower middle part of the inner side of the fixed frame 1. The bottom of the fixed frame 1 is fixedly connected with a base plate 21. The support frames 20 are used for support, and the base plate 21 is used for protection.

[0044] Specifically, the baffle 17 is installed on the fixing frame 1 via the hinge 16 to provide protection for the chain 7. The buckle 18 fixed on the baffle 17, together with the pin 19, can fix the position of the baffle 17. The support frame 20 is used to improve the stability of the fixing frame 1, and the base plate 21 fixed under the fixing frame 1 can provide support for it.

[0045] Working principle: When using the mortar hoist to transport mortar upwards, first start motor 3. The power provided by motor 3 drives the connecting rod 4 below to start rotating. As the connecting rod 4 below starts rotating, the drive sprockets 5 fixed on both sides of it will also rotate. At the same time as the drive sprockets 5 rotate, they will drive the corresponding driven sprockets 6 fixed on both sides of the connecting rod 4 above to rotate synchronously through two chains 7. As the two chains 7 rotate, multiple lifting blocks 8 fixed on their adjacent sides will also be driven to rotate. At this time, the conveying box 9 containing mortar is hooked onto one of the pairs of lifting blocks 8 through the handles on both sides, thus moving the conveying box 9 containing mortar upwards. After using the mortar hoist, only the conveying box 9 needs to be cleaned, thus achieving the effect of preventing mortar from adhering to the mortar hoist.

[0046] To facilitate mortar transportation while the mortar hoist is running, motor 202 is first started. The power provided by motor 202 drives the rotating rod 201 connected to it to rotate. When the rotating rod 201 rotates, the power gear 203 fixed on it will rotate synchronously. As the power gear 203 rotates, it meshes with the adjacent auxiliary wheel 205 fixed by the fixing rod 204, thereby driving the adjacent auxiliary wheel 205 to rotate. The power gear 203 then drives the next power gear 203 to rotate, and so on, driving all the rotating rods 201 and power gears 203 to rotate. The rotation of multiple rotating rods 201 drives the rotation of the conveyor belt 206. Then, the conveyor box 9 is placed on the conveyor belt 206 and sent to the rising lifting block 8. The empty conveyor box 9 is then brought back after being lowered by the lifting block 8, thus achieving the effect of cyclical conveying of the conveyor box 9.

[0047] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
