[0002] When producing premixed mortar, it is necessary to proportion the raw materials of the premixed mortar. A better proportion of raw materials can make the produced premixed mortar more in line with the required standards.

[0003] When proportioning the raw materials for premixed mortar, a weighing device is needed. The weighing device can be used to determine the weight of various raw materials for the premixed mortar. According to the proportion, the appropriate amount of raw materials can be taken to make the premixed mortar, so that the produced premixed mortar is more standardized and of higher quality.

[0004] In order to facilitate the movement of existing weighing equipment during use, universal wheels are added to the bottom of the equipment. However, when in use, after the universal wheels are locked, the contact area between the universal wheels and the ground is small, and the weighing equipment is mostly used in outdoor construction sites. Therefore, the device may still shake due to external forces, which will have a certain impact on the weighing results.

[0005] Therefore, it is necessary to provide a new automatic weighing equipment for premixed mortar raw materials to solve the above technical problems. Utility Model Content

[0014] Compared with the related art, the automatic weighing equipment for premixed mortar raw materials provided by the utility model has the following beneficial effects:

[0015] 1. The utility model drives the driving gear to rotate through the motor, and uses the driving gear to drive the transmission gears on both sides to rotate. At this time, since the threads of the two screws are opposite, when one of the screws rises, the other screw will fall. The moving direction of the screws is converted by the rotation direction of the motor. At this time, the universal wheel and the cone head can be replaced during the operation of the motor. When the universal wheel is lifted, the cone head falls. The cone head is inserted into the ground to fix the base, thereby improving the stability of the base and avoiding the problem that the device shakes due to external force and affects the weighing result.

[0016] 2. The utility model rotates the sleeve rod so that the handle is placed on the ground. At the same time, the sleeve rod and the inner rod can be used to adjust the inclination of the sleeve rod and the inner rod by utilizing the telescopicity of the sleeve rod and the inner rod. After the raw materials are weighed, the conveyor belt transports the container containing the raw materials to the transmission roller. At this time, the transmission roller can be used to send the raw materials away from the base. When the device is used, the sleeve rod is lifted up. At this time, the handle is held and the device can be pushed through the universal wheel, which effectively improves the auxiliary function of the device for the staff in the weighing work.

[0025] It should be noted that the base 1 is a load-bearing body with a strong load-bearing capacity. The electrical appliances on the device can be controlled through the control console 14, and the weighing results can be displayed. When weighing, the container containing the premixed mortar raw materials is placed on the conveyor belt 2, and the conveyor belt 2 can transport the container. During the transportation process, the weighing plate 12 can weigh the premixed mortar raw materials on the conveyor belt 2, which is convenient for workers to mix the raw materials.

[0026] In the embodiments of the present invention, please refer to Figure 1 and Figure 3The four corners of the base 1 are fixedly connected to the mounting frame 3, and both sides of the mounting frame 3 are slidably connected with screws 31, the bottom ends of the screws 31 on both sides of the mounting frame 3 are respectively provided with cone heads 33 and universal wheels 34, the top sides of the mounting frame 3 are rotatably connected with transmission gears 32, the screws 31 are threadedly connected to the transmission gears 32 on the same side, the top of the mounting frame 3 is rotatably connected with a driving gear 37, the driving gear 37 is located between the two transmission gears 32, and the driving gear 37 is meshed with the transmission gears 32 on both sides, a fixing frame 35 is installed on the top of the screw 31, and the fixing frame 35 is fixedly connected to a limiting rod 36 on one side close to the base 1, a motor 38 is fixedly connected to the bottom of the mounting frame 3, and the output end of the motor 38 is fixedly connected to the driving gear 37, the threads of the screws 31 on both sides of the mounting frame 3 are opposite to each other, and the cone heads 33 and the universal wheels 34 are fixedly connected to the bottom ends of the screws 31.

[0027] It should be noted that: turn on the motor 38 to drive the driving gear 37 to rotate. When the driving gear 37 rotates, it can drive the transmission gears 32 on both sides to rotate. When the driving gear 37 rotates forward, since the threads of the two screws 31 are opposite, the screw 31 with the universal wheel 34 will descend, and the screw 31 with the cone head 33 will rise. When the universal wheel 34 contacts the ground and the cone head 33 separates from the ground, the universal wheel 34 can be used to move the device. When the device is moved to the specified position, the motor 38 is controlled to reverse, and the driving gear 37 is used to rotate. 37 drives the transmission gear 32 to reverse, at this time, the screw 31 with the universal wheel 34 rises, and the screw 31 with the cone head 33 descends. When the cone head 33 is inserted into the ground, the universal wheel 34 will be separated from the ground. At this time, the cone head 33 and the screw 31 connected thereto are used to fix and support the base 1. During the rising process of the screw 31, the limiting rod 36 and the mounting groove 11 cooperate, and the fixing frame 35 is used to limit the screw 31, so that when the transmission gear 32 rotates, it can drive the screw 31 to move up and down, while improving the stability of the screw 31 when moving.

[0028] In the embodiments of the present invention, please refer to Figure 1 and Figure 4 Both ends of one side of the base 1 are rotatably connected with a sleeve rod 4, and the end of the sleeve rod 4 away from the base 1 is slidably connected with an inner rod 41, a handle 42 is fixedly connected between the inner rods 41, and a plurality of rotatably connected transmission rollers 43 are installed between the sleeve rods 4, and a knob 44 is threadedly connected to the sleeve rod 4, and a plurality of anti-slip grooves are provided on the knob 44.

[0029] It should be noted that: when weighing, the sleeve rod 4 is rotated so that the handle 42 is placed on the ground. At this time, the knob 44 is rotated to adjust the inclination of the sleeve rod 4 and the inner rod 41 by utilizing the telescopicity of the sleeve rod 4 and the inner rod 41. After the adjustment is completed, the knob 44 is rotated in the opposite direction to fix the sleeve rod 4 and the inner rod 41. After the raw materials are weighed, the conveyor belt 2 will transport the container containing the raw materials to the transmission roller 43. At this time, the transmission roller 43 can be used to transport the raw materials from the base 1. When the device is used, the sleeve rod 4 is lifted. At this time, the handle 42 is held and the base 1 can be pushed in conjunction with the universal wheel 34 to drive the device to move.

[0030] The working principle of the automatic weighing equipment for premixed mortar raw materials provided by the utility model is as follows:

[0031] First, turn on the motor 38 to drive the driving gear 37 to rotate. When the driving gear 37 rotates, it can drive the transmission gears 32 on both sides to rotate. When the driving gear 37 rotates forward, since the threads of the two screw rods 31 are opposite, the screw rod 31 with the universal wheel 34 will descend, and the screw rod 31 with the cone head 33 will rise. When the universal wheel 34 contacts the ground and the cone head 33 separates from the ground, the sleeve rod 4 is lifted. At this time, the handle 42 can be held and the base 1 can be pushed in cooperation with the universal wheel 34 to drive the device to move.

[0032] After the device is moved to the designated position, the motor 38 is controlled to reverse, and the driving gear 37 is used to drive the transmission gear 32 to reverse. At this time, the screw rod 31 with the universal wheel 34 rises, and the screw rod 31 with the cone head 33 descends. When the cone head 33 is inserted into the ground, the universal wheel 34 will be separated from the ground. At this time, the cone head 33 and the screw rod 31 connected thereto are used to fix and support the base 1, and then the sleeve rod 4 is rotated to make the handle 42 rest on the ground. At this time, the knob 44 is turned to adjust the inclination of the sleeve rod 4 and the inner rod 41 by using the telescopicity of the sleeve rod 4 and the inner rod 41. After the adjustment is completed, the knob 44 is rotated in the opposite direction to fix the sleeve rod 4 and the inner rod 41.

[0033] Then, the container containing the premixed mortar raw materials is placed on the conveyor belt 2, and the conveyor belt 2 can transport the container. During the transportation process, the weighing plate 12 can weigh the premixed mortar raw materials on the conveyor belt 2, and the weighing result will be displayed on the console 14;

[0034] After the raw materials are weighed, the motor 38 is continued to be controlled to drive the driving gear 37 to rotate forward. At this time, the screw 31 with the universal wheel 34 will descend, and the screw 31 with the cone head 33 will rise. When the universal wheel 34 contacts the ground and the cone head 33 separates from the ground, the universal wheel 34 and the screw 31 connected thereto can be converted to support the base 1. Then the sleeve rod 4 is lifted. At this time, the handle 42 can be held and the base 1 can be pushed in conjunction with the universal wheel 34 to drive the device to move.
