Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction equipment technology, and in particular to a mortar mixing feeding device. Background Technology
[0002] In construction projects, raw materials such as sand, cement, and water are put into a mixer to mix and produce mortar. With the development of technology, in order to reduce labor intensity, raw materials such as sand and cement are also transported through a feeding device.
[0003] In the process of conveying raw materials such as sand and cement, the existing feeding devices will cause the raw materials such as sand and cement to adhere to the inside of the feeding device, which will narrow the internal channel of the feeding device and reduce the transportation efficiency. The feeding device is cleaned by manually rinsing with water. However, the water flow is not enough to directly wash the corners and other parts of the feeding device. It is often necessary to soak them in water for a long time to achieve cleaning, which makes each cleaning take a long time. Summary of the Invention
[0004] This utility model provides a feeding device for mortar mixing. By vibrating, it accelerates the removal of residues attached to the main feeding box, feeding hose and flexible feeding screw shaft. This vibration mode can achieve a mortar residue peeling rate of more than 98% on the inner wall of the main feeding box, feeding hose and the surface of the flexible feeding screw shaft, which is much more efficient than traditional manual water flushing and prevents materials from accumulating in dead corners of the pipeline.
[0005] This utility model provides a feeding device for mortar mixing, specifically including a main feeding box, a feeding hose, and a lower base. The feeding hose is fixedly connected to one side of the main feeding box, and the lower base is provided below the main feeding box. A flexible feeding screw shaft is rotatably installed in the middle of the main feeding box. The flexible feeding screw shaft is made of spring steel and has elastic deformation capability. A side drive motor is fixedly installed in the middle of the main feeding box, and a medium vibration motor is fixedly connected to the lower part of the main feeding box. The medium vibration motor has a vibration frequency of 20-50Hz and an amplitude of 2-3mm to prevent material from clumping and clogging. Lower limit brackets are symmetrically fixedly connected to both sides of the main feeding box to accelerate the falling off of residues attached to the main feeding box, the feeding hose, and the flexible feeding screw shaft through vibration.
[0006] Furthermore, the rotating shaft of the side drive motor is fixedly connected to the first end of the flexible feeding screw shaft, and the rear section of the flexible feeding screw shaft extends to the inner side of the feeding hose to form a screw pushing section. The elastic structure of the flexible feeding screw shaft can adapt to the conveying scenario where the bending angle of the feeding hose is ≤45°.
[0007] Furthermore, an upper vertical extension frame is slidably connected to the upper outer side of the lower limit bracket in the vertical direction. The upper vertical extension frame moves upward to expand and adapt to the increase in vertical height after the feeding hose is spirally wound. An upper horizontal limit frame is rotatably connected to the top of the upper vertical extension frame in the horizontal direction. The upper horizontal limit frame is used to limit the vertical swing of the feeding hose. The bottom of the upper horizontal limit frame and the top of the feeding hose are in contact.
[0008] Furthermore, the first end of the feeding hose is fixedly connected to a first fixing ring, and the outer side of the first fixing ring is circumferentially rotatably connected to an outer rotating ring. The outer side of the outer rotating ring is fixedly connected to an outer fixing clamp. The first ends of the outer fixing clamp and the first ends of the outer sliding clamp are slidably connected to each other. The outer fixing clamp and the outer sliding clamp move close to the upper horizontal limit frame for position fixing.
[0009] Furthermore, the first end of the external fixed clamp is rotatably connected to a threaded rod, which is threadedly connected to the first end of the external sliding clamp. When rotating, it drives the external sliding clamp to translate, thereby adjusting the clamping force on the frame and other fixed positions. The external fixed clamp and the external sliding clamp can also clamp and connect to the mixing equipment.
[0010] Furthermore, upper buffer blocks are symmetrically fixedly connected to both sides of the top of the lower base. The top of the upper buffer blocks is fixedly connected to the bottom of the main feeding box. The upper buffer blocks are made of polyurethane.
[0011] Furthermore, the lower limit bracket has a Y-shaped structure, and the width of the two upper support rods of the lower limit bracket is greater than the diameter of the feeding hose. The feeding hose is folded around the Y-shaped lower limit bracket.
[0012] This utility model provides a feeding device for mortar mixing, which has the following beneficial effects:
[0013] After the feeding operation stops, the medium-frequency vibration motor works in conjunction with the machine to achieve efficient residue removal. The medium-frequency vibration motor adopts variable frequency adjustable technology and can output a wide frequency vibration of 20-50Hz. It can generate high-frequency vibration within 30 seconds after the machine stops. The vibration accelerates the removal of residues attached to the main feeding box, feeding hose and flexible feeding screw shaft. According to actual tests, this vibration mode can achieve a mortar residue peeling rate of over 98% on the inner wall of the main feeding box, feeding hose and flexible feeding screw shaft. This is much more efficient than traditional manual water flushing, prevents material from accumulating in dead corners of the pipeline, reduces the possibility of the main feeding box, feeding hose and flexible feeding screw shaft being blocked by residues, and significantly reduces operation and maintenance costs.
[0014] By combining the lower limit bracket with the feeding hose, efficient pipe storage is achieved. The feeding hose is made of high-strength rubber and fiber braided composite material, which has bending performance and can be quickly folded around along the guide of the Y-shaped lower limit bracket. After folding, the space occupied by the hose is reduced by 50% compared with the unfolded state, effectively solving the problem of inconvenient transportation of traditional pipelines.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0029] Example 1: Please refer to Figures 1 to 6 :
[0030] This utility model discloses a feeding device for mortar mixing, including a main feeding box 1, a feeding hose 2, and a lower base 3. A flexible feeding screw shaft 101 is rotatably mounted in the middle of the main feeding box 1. The flexible feeding screw shaft 101 is made of spring steel and has elastic deformation capability. A side drive motor 102 is fixed in the middle of the main feeding box 1, and a central vibration motor 103 is fixedly connected to the lower part of the main feeding box 1. The central vibration motor 103 has a vibration frequency of 20-50Hz and an amplitude of 2-3mm, used to prevent material from vibrating. To prevent blockage, lower limit brackets 104 are symmetrically fixedly connected to both sides of the main feeding box 1. Vibration accelerates the removal of residues attached to the main feeding box 1, the feeding hose 2, and the flexible feeding screw shaft 101. The shaft of the side drive motor 102 is fixedly connected to the head end of the flexible feeding screw shaft 101. The rear section of the flexible feeding screw shaft 101 extends to the inside of the feeding hose 2, forming a screw pushing section. The elastic structure of the flexible feeding screw shaft 101 can adapt to conveying scenarios where the bending angle of the feeding hose 2 is ≤45°, avoiding rigid jamming.
[0031] A feeding hose 2 is fixedly connected to one side of the main feeding box 1. A first fixing ring 201 is fixedly connected to the first end of the feeding hose 2. An outer rotating ring 202 is rotatably connected to the outer side of the first fixing ring 201. An outer fixing clamp 203 is fixedly connected to the outer side of the outer rotating ring 202. The first ends of the outer fixing clamp 203 and the first ends of the outer sliding clamp 204 are slidably connected to each other. The outer fixing clamp 203 and the outer sliding clamp 204 move closer to the upper horizontal limit frame 106 to fix their positions, ensuring that the hose remains fixed during movement. A lower base 3 is provided below the main feeding box 1. Upper buffer rubber blocks 301 are symmetrically fixedly connected to both sides of the top of the lower base 3. The top of the upper buffer rubber blocks 301 is fixedly connected to the bottom of the main feeding box 1. The upper buffer rubber blocks 301 are made of polyurethane, with a compression permanent deformation of ≤10%, which can absorb the vibration energy of the equipment and block the vibration transmission between the main feeding box 1 and the lower base 3.
[0032] In this embodiment, an upper vertical extension frame 105 is slidably connected to the upper outer side of the lower limit bracket 104 in the vertical direction. The upper vertical extension frame 105 moves upward to expand and adapt to the increase in vertical height after the feeding hose 2 is spirally wound. An upper horizontal limit frame 106 is rotatably connected to the top of the upper vertical extension frame 105 in the horizontal direction. The upper horizontal limit frame 106 is used to limit the vertical swing of the feeding hose 2. The bottom of the upper horizontal limit frame 106 and the top of the feeding hose 2 are in contact, thereby limiting the position and height of the upper horizontal limit frame 106 and the lower limit bracket 104.
[0033] In this embodiment, the first end of the outer fixed clamping plate 203 is rotatably connected to a threaded rod 205. The threaded rod 205 and the first end of the outer sliding clamping plate 204 are threadedly connected. When rotating, the outer sliding clamping plate 204 is driven to translate, thereby adjusting the clamping force on the frame and other fixed positions. The outer fixed clamping plate 203 and the outer sliding clamping plate 204 can also clamp and connect to the mixing equipment, so that the discharge end of the feeding hose 2 is fixed at the inlet of the mixing equipment.
[0034] In this embodiment, the lower limit bracket 104 has a Y-shaped structure. The width of the two upper support rods of the lower limit bracket 104 is greater than the diameter of the feeding hose 2. After the feeding hose 2 is folded around the Y-shaped lower limit bracket 104, the space occupied by the hose is reduced by 50% compared with the unfolded state, which effectively solves the problem of inconvenience in traditional pipeline transportation.
[0035] In this second embodiment, based on the first embodiment, the bottom of the lower base 3 is equipped with a pulley with a brake, so that the lower base 3 can move quickly along the ground via the pulley, which facilitates the displacement of the equipment.
[0036] The working principle of this embodiment is as follows: The lower base 3 is placed on the ground. Mortar or cement is added into the main feeding box 1. The side drive motor 102 starts, driving the flexible feeding screw shaft 101 to rotate. The flexible feeding screw shaft 101 pushes the mortar or cement in the main feeding box 1 axially to the feeding hose 2. The flexible feeding screw shaft 101 continues to rotate in the feeding hose 2, pushing the mortar or cement in the feeding hose 2 to move, conveying the mortar or cement to the outlet at the other end of the feeding hose 2, and then to the mortar mixing equipment. After the feeding operation stops, the intermediate vibration motor 103 works in conjunction to achieve efficient residue removal. The intermediate vibration motor 103 adopts variable frequency adjustable technology and can output a wide frequency vibration of 20-50Hz, generating high-frequency vibration with an amplitude of 2-3mm within 30 seconds after stopping. Vibration accelerates the removal of residues adhering to the main feeding box 1, the feeding hose 2, and the flexible feeding screw shaft 101. Actual measurements show that this vibration mode can achieve a mortar residue removal rate of over 98% on the inner walls of the main feeding box 1, the feeding hose 2, and the surface of the flexible feeding screw shaft 101. This significantly improves cleaning efficiency compared to traditional manual flushing. During vibration, the elastic material of the flexible feeding screw shaft 101 effectively buffers mechanical stress, preventing structural damage caused by rigid vibration, preventing material accumulation in pipe dead corners, reducing the likelihood of blockages on the main feeding box 1, the feeding hose 2, and the flexible feeding screw shaft 101, and significantly reducing maintenance costs. Vibration buffering is achieved between the main feeding box 1 and the lower base 3 via an upper buffer rubber block 301, blocking vibration transmission between them, allowing the lower base 3 to be installed more stably on the ground.
[0037] The lower limit bracket 104 and the feeding hose 2 work together to achieve efficient pipe storage. The feeding hose 2 slides into the middle of the lower limit bracket 104. The upper vertical extension bracket 105 moves upward to accommodate the increased vertical height of the feeding hose 2 after it is spirally wound. The upper horizontal limit bracket 106 is located at the top of the feeding hose 2, with its bottom and top fitting together. This restricts the position and height of the upper horizontal limit bracket 106 and the lower limit bracket 104, eliminating the need for the lower limit bracket 104 to be fixed at a fixed height. The upper horizontal limit bracket 106 rotates horizontally to one side of the feeding hose 2 to avoid affecting the installation of the feeding hose 2 and the lower limit bracket 104. The feeding hose 2 is made of a high-strength rubber and fiber braided composite material, which has bending properties. In terms of performance, after the feeding hose 2 is folded around the Y-shaped lower limit bracket 104, the space occupied by the hose is reduced by 50% compared with the unfolded state, effectively solving the problem of inconvenient transportation of traditional pipelines. At the same time, the locking structure formed by the outer sliding clamp 204 and the outer fixed clamp 203, the thread of the threaded rod 205 drives the outer sliding clamp 204 to move, and the outer fixed clamp 203 and the outer sliding clamp 204 move close to the clamping upper horizontal limit bracket 106 to fix the position, ensuring that the hose remains fixed during the movement, improving the safety and convenience of equipment transportation. During the material transportation process, the outer fixed clamp 203 and the outer sliding clamp 204 can also clamp and connect to the mixing equipment, so that the discharge end of the feeding hose 2 is fixed at the inlet of the mixing equipment for feeding.
