[0003] A Chinese patent search disclosed a raw material metering device for entering the kiln (publication number CN202321605378.5). This patented technology pushes the raw material at the feed port through an anti-blocking mechanism to prevent the raw material from being blocked at the feed port, thereby preventing the overall working efficiency of the device from being reduced. The device needs to be cleaned regularly after the work is completed. This anti-blocking mechanism will affect the cleaning work inside the device, making it inconvenient to clean the inside of the device, indirectly affecting the working efficiency of the device. Therefore, a person skilled in the art provides a raw material metering device for entering the kiln to solve the problems raised in the above background technology. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figure 1-Figure 4 The raw material metering device shown in the figure comprises a support base 1, a scale frame 2 is arranged inside the support base 1, a scale body 8 is rotatably connected inside the scale frame 2, a crank 11 is rotatably connected to the bottom end of the scale frame 2, a threaded rod 12 is fixedly connected to the top end of the crank 11, a pressure block 13 is fixedly connected to the top end of the threaded rod 12, a plurality of pressure rods 15 are slidably connected inside the scale body 8, a first spring 16 is sleeved on the outer surface of the pressure rod 15 located inside the scale body 8, a storage box 17 is fixedly connected to the top end of the scale frame 2, a cleaning broom 18 is arranged inside the storage box 17, and the cleaning broom The inner sliding connection of both sides of the handle 18 is provided with a buckle 19, and the outer surface of the buckle 19 is provided with a second spring 20. The threaded rod 12 is rotated by turning the crank 11, and the pressure block 13 can be lifted or lowered through the cooperation between the threaded rod 12 and the scale frame 2. The lifted or lowered pressure block 13 can drive the pressure rod 15 to move left and right, thereby controlling the contraction of the rotor blades 14, so that the space inside the scale body 8 becomes larger, which will not affect the cleaning of the inside of the scale body 8. At the same time, the cleaning broom 18 can be loosened to clean the scale body 8, eliminating the process of disassembling various parts and saving cleaning time.

[0021] A motor bracket 4 is fixedly connected to the top of one side of the support seat 1, a driving motor 5 is installed on the top of the motor bracket 4, an output end of the driving motor 5 is fixedly connected to a linear reducer 6, an output end at the bottom of the linear reducer 6 is fixedly connected to a connecting shaft 7, the connecting shaft 7 passes through the scale frame 2 and is fixedly connected to the scale body 8, and the linear reducer 6 is used to change the high-speed and low-torque motion characteristics of the driving motor 5, thereby achieving a low-speed and high-torque effect suitable for use with this device.

[0022] The top of the support seat 1 is fixedly connected with four limit bolts 3, and the outer side of the scale frame 2 is fixedly connected with the limit bolts 3. The support seat 1 is connected to the scale frame 2 through the four limit bolts 3. When the material falls into the scale body 8, vibration will be generated. When the frequency is high and the time is long, it is very easy to cause damage to the device. The limit bolts 3 can play a buffering role to protect the device.

[0023] A feed port 9 is provided on one side of the top end of the scale frame 2, and a discharge port 10 is provided on one side of the bottom end of the scale frame 2. Both the feed port 9 and the discharge port 10 are connected to the scale body 8. The feed port 9 is used to connect the feed hopper, so that the required raw material can be delivered into the device for weighing, and the discharge port 10 can discharge the weighed raw material.

[0024] One end of multiple pressure rods 15 cooperates with the pressure block 13, and the other end of the pressure rod 15 is fixedly connected to the rotor blade 14. The rotor blade 14 is in a sliding connection with the scale body 8. The rotor blade 14 guides the raw material entering the scale body 8 so that the raw material can be discharged from the discharge port 10 after weighing.

[0025] The buckle 19 cooperates with the two sides of the storage box 17 through the second spring 20. The storage box 17 restricts the cleaning broom 18 through the two buckles 19. The storage box 17 can store the cleaning broom 18 to prevent the cleaning broom 18 from affecting the weighing of raw materials. The buckle 19 facilitates the fixing of the cleaning broom 18 to prevent the cleaning broom 18 from falling due to the vibration generated by the device, thereby affecting the operation of the device.

[0026] Working principle: first, connect the feed port 9 with the feed hopper, so that when the feed hopper discharges raw materials, the raw materials can directly enter the inside of the scale body 8 through the feed port 9, and then the scale body 8 can weigh the raw materials. At the same time, the rotor blades 14 can divide the space in the scale body 8 into multiple parts, and through the action of the driving motor 5, the weight of the raw materials between every two rotor blades 14 is exactly the same, and then each portion of raw materials with the same weight can be sent to the discharge port 10, and can be used directly after discharge. The device needs to be cleaned after multiple uses, but it is time-consuming to clean it after each use. However, the present device can quickly clean the inside of the scale body 8 after each use. For fast cleaning, first turn the crank 11 to retract the rotor blades 14, increase the space inside the scale body 8, and allow the cleaning broom 18 to clean the inside of the scale body 8, then unfasten the restriction of the buckle 19 on the cleaning broom 18, and push the cleaning broom 18 deep into the inside of the scale body 8 to clean. Although the cleaning degree is not as good as that of disassembling the device for cleaning, the cleaning speed is very fast, which facilitates the device to be quickly put into use next time. After multiple cleanings using this method, and when there is no need to put it into work quickly, the device can be disassembled for a complete cleaning. The main purpose is to enable the device to be put into use quickly and to prevent the raw material formula from being different each time, which will cause mixing and affect the use of the raw material.

[0027] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
