[0002] With the increasing intensity of coal mining, the cross-sectional size of the tunnel continues to increase, and the tunnel foundation reinforcement and working face support work have become more important, which puts higher requirements on the reliability of anchor support technology.

[0003] As a new type of support material, polyurethane has a designable molecular structure and can be used for reinforcement and support at the junction of coal mining working face and tunnel and during tunnel excavation with soft and broken surrounding rock.

[0004] During the production of polyurethane anchoring agents, a reactor is required to complete the chemical reaction between various raw materials, thereby preparing anchoring agent products that meet the requirements. During the production process of polyurethane anchoring agents, precise control of the input amount and timing of raw materials is a key factor in ensuring product quality.

[0005] Traditional polyurethane anchoring agent production often presents numerous challenges during the material feeding process. Typically, a specific amount of raw materials is manually weighed and then fed. This is not only labor-intensive but also difficult to ensure accuracy and consistency in weighing and feeding, which can easily lead to fluctuations in product quality. Furthermore, manual operation is inefficient, making it difficult to meet the demands of large-scale production. This increases labor costs and management complexity, severely hindering improvements in production efficiency and product quality. Utility Model Content

[0023] Example 1

[0024] See also Figures 1 to 4 The utility model provides a polyurethane anchoring agent production device, comprising a reactor 1, a plurality of feeding units 2 are arranged at the feeding pipe mouth of the reactor 1, the feeding unit 2 comprises a mounting base 3 fixedly arranged on the reactor 1, two connecting rods 4 are rotatably arranged on the mounting base 3, and the two connecting rods 4 are connected by two resetters 5;

[0025] The movable ends of the two connecting rods 4 are rotatably connected to the adapter, and a quantitative feeder 6 is fixedly set on the adapter. The inlet end of the quantitative feeder 6 is connected to a silo through a pipeline, and the outlet end faces the reactor 1. The bottom end of the silo is higher than the inlet end of the quantitative feeder 6.

[0026] Each quantitative feeder 6 corresponds to a silo, in which the required raw materials are placed. Since multiple raw materials are needed in the production of polyurethane anchoring agents, and the addition ratio and addition timing of each raw material have a crucial impact on the quality of the final product, each feeding unit corresponds to a specific raw material and quantitative feeder, which can more accurately control the input amount of each raw material, ensure the accuracy of the ratio between the raw materials, and help to ensure the stability and consistency of product quality.

[0027] The quantitative feeder 6 accurately controls the amount of raw materials added according to the preset amount; its working principle is generally based on the following methods:

[0028] Volumetric quantitative feeding: The material is held in a cavity of a certain volume. Each time the material is added, the cavity is filled with material before it is transported out, thereby achieving quantitative feeding. For example, in a plunger-type quantitative feeder, the plunger stroke and the volume of the cavity determine the feeding amount.

[0029] Weighing quantitative: first measure the weight of the empty container, then measure the total weight in real time during the feeding process, and stop feeding when the total weight reaches the set feeding amount;

[0030] Flow-type quantitative measurement: Use flow sensors to measure the flow rate of materials, and calculate and control the feeding amount based on the feeding time;

[0031] During operation, the quantitative feeder receives instructions from the control system and accurately transports materials according to the set feeding amount. The control system adjusts the working state of the feeder based on feedback information such as weight, volume, flow, etc. to ensure the accuracy and stability of feeding.

[0032] The quantitative feeder 6 is prior art and will not be described in detail here;

[0033] Before starting the equipment, the required raw materials are placed in the corresponding silos respectively. When raw materials need to be added to the reactor 1, the user moves the adapter so that the outlet end of the quantitative feeder 6 is located above the feeding nozzle of the reactor 1, which is convenient for adding raw materials into the reactor 1. After the feeding is completed, the quantitative feeder 6 is reset to the initial state under the action of the resetter, and the feeding unit 2 will not block the top of the feeding nozzle, which is convenient for subsequent feeding operations.

[0034] The resetter 5 includes an upper connecting member 7 rotatably connected to one of the connecting rods 4, and a lower connecting member 8 rotatably connected to the other connecting rod 4. A sleeve 9 is fixedly provided on the upper connecting member 7, and a sliding rod 10 is fixedly provided on the lower connecting member 8. The sleeve 9 is sleeved on the outside of the sliding rod 10, and a spring 11 is provided on the outside of the sleeve 9. The two ends of the spring 11 are respectively fixed to the upper connecting member 7 and the lower connecting member 8.

[0035] When the user moves the adapter to change its position, the relative position of the connecting rod 4 also changes, and the upper connecting member 7 and the lower connecting member 8 connected to the connecting rod 4 also move accordingly; at this time, the sleeve 9 sleeved on the outside of the sliding rod 10 will slide along the sliding rod 10, compressing the spring 11;

[0036] When the feeding is completed and the user releases the force on the adapter, the spring 11 will quickly release the stored energy; the elastic force of the spring 11 pushes the upper connecting piece 7 and the lower connecting piece 8, causing the sleeve 9 to slide in the opposite direction along the sliding rod 10, thereby driving the connecting rod 4 back to the initial position, and realizing the reset of the quantitative feeder 6; during the whole process, the spring of the resetter 6 ensures that the connecting rod 4 and the quantitative feeder 6 can be accurately and quickly restored to their original positions through the telescopic action, which will not affect the next feeding, and also facilitates the user to manually feed through the feeding port.

[0037] Each connecting rod 4 includes two parallel supporting rods 12 . The two supporting rods 12 are respectively located on both sides of the mounting seat 3 and the adapter seat. The two resetters 5 are located on the outside of the two supporting rods 12 .

[0038] Since the two parallel support rods 12 are respectively located on both sides of the mounting seat 3 and the adapter seat, the structure is more stable and the force is more uniform during the movement and resetting process, and the position adjustment and resetting of the quantitative feeder 6 can be achieved more accurately, ensuring the accuracy and efficiency of the feeding operation.

[0039] A handle 13 is fixedly provided on each side of the adapter.

[0040] When adding raw materials to the reactor, the operator holds the handles 13 fixed on both sides of the adapter and moves the adapter by pushing or pulling the handles 13 to drive the outlet end of the quantitative feeder 6 to the appropriate position above the feeding nozzle of the reactor 1.

[0041] A control switch is provided on the handle 13 , and the control switch and the quantitative feeder 6 form an electric control circuit.

[0042] While holding the handle 13, the operator can conveniently operate the control switch provided on the handle 13; when the control switch is pressed, the electric control circuit formed by the control switch and the quantitative feeder 6 is connected, and the quantitative feeder 6 starts working to feed a preset amount of raw materials into the reactor.

[0043] When the present invention is used, before starting the equipment, the required raw materials are placed in the corresponding silos respectively. When raw materials need to be added to the reactor 1, the user moves the adapter so that the outlet end of the quantitative feeder 6 is located above the feeding nozzle of the reactor 1, which is convenient for adding raw materials into the reactor 1. After the feeding is completed, the quantitative feeder 6 is reset to the initial state under the action of the resetter, and the feeding unit 2 will not block the upper part of the feeding nozzle, which is convenient for subsequent feeding operations.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
