Abstract

This utility model relates to the field of mortar production technology and discloses an additive addition device for mortar production, including an installation plate with four positioning holes arranged in a rectangular array. A conveying pipe is fixedly installed on the installation plate. The additive addition device feeds the additive into a weighing hopper, which then weighs and measures the amount of additive according to the discharge rate set by the quantitative addition equipment control system. A drive motor then rotates a auger conveyor to quantitatively add the additives used in mortar production into the mortar. A blower is then turned on, sending airflow into the conveying pipe. This airflow causes any remaining additives in the conveying pipe to be discharged from the discharge port and added to the mortar, thus preventing additive residue from affecting the actual amount of additives added to the mortar.

Description

Technical Field

[0001] This utility model relates to the field of mortar production technology, specifically to an additive adding device for mortar production. Background Technology

[0002] Mortar is a binding material used in bricklaying. It is made by mixing sand and cementing materials (cement, lime paste, clay, etc.) with water in a certain proportion. It is also called mortar or grout. Common types of mortar include cement mortar, mixed mortar, lime mortar, and clay mortar. During the production of mortar, some additives such as mortar king, mortar treasure, cement additives, liquid and powder additives are added to improve the performance of the mortar.

[0003] Most additives used in mortar production are powder additives. When these additives are fed into the mortar production equipment using a metering machine, the powder additives are relatively light and a small amount may remain inside the adding device. This affects the actual amount of additive added. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an additive addition device for mortar production, which solves the problem that most of the additives used in mortar production mentioned in the background are powder additives. When these additives are fed into the mortar production equipment using a quantitative additive machine, the powder additives are prone to leaving a small amount inside the addition device due to their light weight, thus affecting the actual amount of additives added.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an additive addition device for mortar production, comprising an installation plate, four positioning holes arranged in a rectangular array on the installation plate, a conveying pipe fixedly mounted on the installation plate, a connecting pipe at the upper end of the conveying pipe, a weighing hopper on the connecting pipe, a one-way valve inside the connecting pipe, a fixing plate fixedly mounted on the rear end surface of the conveying pipe, a fan fixedly mounted on the fixing plate, an air supply pipe at the air outlet of the fan extending into the conveying pipe, and an air inlet at the front end of the fan.

[0006] Using the above technical solution, after the additive is fed into the weighing hopper, the weighing hopper can weigh and measure the amount of material according to the discharge rate set by the quantitative addition equipment control system. Then, the drive motor drives the auger conveyor to rotate, thereby quantitatively feeding the additives used in mortar production into the mortar. After that, the blower is turned on, so that the blower sends air into the conveying pipe. Then, the air force will drive the additives remaining in the conveying pipe to be discharged from the discharge port of the conveying pipe and sent into the mortar, thereby preventing the additives from remaining in the conveying pipe and affecting the actual amount of additives added to the mortar.

[0007] Preferably, a drive motor is fixedly installed on the fixed plate, the output end of the drive motor extends through the conveying pipe into the conveying pipe, and a auger conveyor is fixedly installed at the output end of the drive motor.

[0008] Using the above technical solution, by turning on the drive motor, the auger conveyor installed on the output end is driven to rotate. After the additive enters the conveying pipe, the auger conveyor will send the additive into the mortar through the conveying pipe.

[0009] Preferably, the conveying pipe is L-shaped, and a first threaded block is provided on the outer surface of the discharge end of the conveying pipe.

[0010] By adopting the above technical solution, the L-shaped shape of the conveying pipe can better deliver the additives into the mortar. The first threaded block set on the outer surface of the discharge end of the conveying pipe facilitates the adjustment of the first shrinkage tube.

[0011] Preferably, the bottom discharge end of the conveying pipe is provided with a first shrink tube, a second threaded block is fixedly installed on the outer end surface of the first shrink tube, and a first threaded groove is opened at the inner end of the first shrink tube, and the first threaded groove and the first threaded block are engaged with each other.

[0012] By adopting the above technical solution, by rotating the first shrink tube, the first threaded groove set in the first shrink tube is extended along the thread of the first threaded block, thereby extending the outlet and preventing the additive from flying out when it is added to the mortar.

[0013] Preferably, a second shrink tube is provided at the outer end of the first shrink tube, and a second threaded groove is provided at the inner end of the second shrink tube, and the second threaded groove and the second threaded block mesh with each other.

[0014] By adopting the above technical solution, the second threaded groove inside the second shrink tube is extended downward along the thread on the second threaded block at the outer end of the first shrink tube by rotating the second shrink tube. This can effectively extend the discharge port and prevent the additive from flying out when it is added to the mortar.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This mortar production additive addition device, after the additive is fed into the weighing hopper, the weighing hopper can weigh and measure the amount of material according to the discharge rate set by the quantitative addition equipment control system. Then, the drive motor drives the auger conveyor to rotate, thereby quantitatively feeding the additives used in mortar production into the mortar. After that, the blower is turned on, so that the blower sends air into the conveying pipe. Then, the air will drive the additives remaining in the conveying pipe to be discharged from the discharge port of the conveying pipe and sent into the mortar, thereby preventing the additives remaining in the conveying pipe from affecting the actual amount of additives added to the mortar.

[0017] 2. The additive addition device for mortar production, by rotating the first shrink tube, causes the first threaded groove inside the first shrink tube to extend along the thread of the first threaded block. After the first shrink tube is adjusted, the operator rotates the second shrink tube, causing the second threaded groove inside the second shrink tube to extend downward along the thread of the second threaded block at the outer end of the first shrink tube. This can effectively extend the discharge port and prevent the additive from flying out when it is added to the mortar. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Example 1:

[0025] Referring to Figures 1-4, an additive addition device for mortar production is described. The mounting plate 1 has four positioning holes 2 arranged in a rectangular array. A conveying pipe 3 is fixedly mounted on the mounting plate 1. A connecting pipe 4 is located at the upper end of the conveying pipe 3. A weighing hopper 5 is mounted on the connecting pipe 4. A one-way valve 6 is installed inside the connecting pipe 4. A fixing plate 7 is fixedly mounted on the rear end surface of the conveying pipe 3. A fan 8 is fixedly mounted on the fixing plate 7. An air supply pipe 9 is located at the air outlet of the fan 8, extending into the conveying pipe 3. An air inlet 10 is located at the front end of the fan 8. A drive motor 11 is fixedly mounted on the fixing plate 7. The output end of the drive motor 11 extends through the conveying pipe 3 and into the conveying pipe 3. A auger conveyor 12 is fixedly mounted at the output end of the drive motor 11.

[0026] Working Principle: The four positioning holes 2 on the mounting plate 1 facilitate the installation of the additive device by the operator. When additives used in mortar production need to be added, the operator turns on the drive motor 11, which drives the auger conveyor 12 installed on the output end to rotate. The operator then feeds the additive into the weighing hopper 5. The weighing hopper 5 weighs and measures the amount of additives according to the discharge rate set by the quantitative additive control system. This allows the additives needed for mortar production to be fed into the conveying pipe 3 through the connecting pipe 4. The drive motor 11 then drives the auger conveyor 12 to rotate, thus quantitatively feeding the additives used in mortar production into the conveying pipe 3. When the mortar is filled with mortar, since the mortar additive is in powder form, some additive may remain in the conveying pipe 3. Therefore, after the quantitative amount of additive is conveyed, the operator turns on the blower 8, which draws air from the outside through the air inlet 10 and then sends the air into the conveying pipe 3 through the air supply pipe 9. The air force will then drive the additive remaining in the conveying pipe 3 out of the discharge port of the conveying pipe 3 and into the mortar, thus preventing the additive from remaining in the conveying pipe 3 and affecting the actual amount of additive added to the mortar. The one-way valve 6 set on the connecting pipe 4 can effectively prevent the additive from entering the weighing hopper 5 due to the influence of the air force of the blower 8.

[0027] Example 2:

[0028] Referring to Figures 1-4, an additive addition device for mortar production is described. The conveying pipe 3 is L-shaped. A first threaded block 13 is provided on the outer surface of the discharge end of the conveying pipe 3. A first shrinkage pipe 14 is provided at the bottom discharge end of the conveying pipe 3. A second threaded block 15 is fixedly installed on the outer end surface of the first shrinkage pipe 14. A first threaded groove 16 is opened at the inner end of the first shrinkage pipe 14. The first threaded groove 16 and the first threaded block 13 are engaged with each other. A second shrinkage pipe 17 is provided at the outer end of the first shrinkage pipe 14. A second threaded groove 18 is opened at the inner end of the second shrinkage pipe 17. The second threaded groove 18 and the second threaded block 15 are engaged with each other.

[0029] Working principle: When adding additives to mortar, the operator can rotate the first shrink tube 14, causing the first threaded groove 16 inside the first shrink tube 14 to extend along the thread of the first threaded block 13. After the first shrink tube 14 is adjusted, the operator rotates the second shrink tube 17, causing the second threaded groove 18 inside the second shrink tube 17 to extend downward along the thread on the second threaded block 15 at the outer end of the first shrink tube 14. This can effectively extend the outlet and prevent the additive from flying out when it is added to the mortar.
