Technical Field
[0001] This utility model relates to the field of construction machinery technology, and in particular to an environmentally friendly screw conveyor feeding device for inorganic thermal insulation mortar. Background Technology
[0002] In the construction process, inorganic thermal insulation and environmentally friendly mortar is widely used in wall insulation projects due to its excellent thermal insulation performance and environmental protection characteristics. As a key piece of equipment for conveying inorganic thermal insulation and environmentally friendly mortar, the screw conveyor feeding device directly affects the construction quality and progress in terms of its feeding efficiency and stability. Existing mortar screw conveyor feeding devices have significant shortcomings when dealing with inorganic thermal insulation and environmentally friendly mortar containing fibers and lightweight aggregates: during the feeding process, the material is prone to agglomeration and bridging due to its composition characteristics, and most devices adopt a single conveying and pushing mode, resulting in insufficient material pushing force in the feeding cylinder. When a single component is overloaded, it is easy to cause material retention. At the same time, the contact area between the conveying blades and the material is large, and the mortar is easy to adhere to the blade surface, which not only affects the smoothness of blade operation, but also further aggravates the material agglomeration problem, ultimately significantly reducing the overall conveying efficiency. Utility Model Content
[0003] This utility model relates to a feeding device for an inorganic thermal insulation environmentally friendly mortar screw conveyor, in order to solve the problems mentioned in the background art regarding existing mortar screw conveyor feeding devices. Because inorganic thermal insulation environmentally friendly mortar contains fibers and lightweight aggregates, material agglomeration and bridging are prone to occur during feeding; moreover, most devices are single conveying modes, resulting in insufficient material pushing force in the feeding cylinder, and excessive load on a single component can easily lead to material retention. At the same time, the large contact area between the conveying blades and the material makes the mortar prone to adhesion, further affecting the conveying efficiency.
[0004] This utility model provides an inorganic thermal insulation environmentally friendly mortar screw press feeding device, specifically including: a feeding hopper; a feeding cylinder is fixedly connected to the bottom front side of the feeding hopper, the feeding cylinder and the inside of the feeding hopper are connected, a combined baffle is fixedly installed at the bottom of the rear side wall of the feeding hopper, a drive motor is fixedly installed in the middle of the rear side wall of the combined baffle, and a rotating disk is rotatably connected to the front side wall of the combined baffle.
[0005] Furthermore, the top left and right inner walls of the feed hopper are equipped with horizontally equidistant blocking bars, and the bottom of the rear inner wall of the feed hopper is provided with a circular inner groove, with a limit stop ring fixedly installed at the front end of the inner groove.
[0006] Furthermore, six connecting rods are installed in a ring at equal intervals in the middle of the front side wall of the combined baffle. A transmission gear is rotatably connected to each connecting rod at intervals. An inner extension cylinder is fixedly connected to the front end of the connecting rod, and the inner extension cylinder is located in the feed hopper.
[0007] Furthermore, the front drive shaft of the drive motor is connected through the middle of the combined baffle and the inner extension cylinder on the front side of the combined baffle. The rear end of the drive shaft is fixedly connected to a meshing gear, which meshes with the transmission gear sleeved between the connecting rod between the combined baffle and the inner extension cylinder. The front end of the drive shaft is fixedly connected to a spiral conveying shaft, and the spiral blades of the spiral conveying shaft are provided with through holes.
[0008] Furthermore, the inner ring of the rotating disk has a gear ring that meshes with the transmission gear sleeved on the connecting rod between the combined baffle and the inner extension cylinder. The front side wall of the rotating disk has six connecting posts installed in a ring at equal intervals. The front end of the connecting posts is fixedly connected to a rotating ring. The front end of the outer side wall of the rotating ring has a limiting groove. The rotating ring is rotatably connected to an inner groove at the bottom of the rear inner wall of the feed hopper. The limiting groove is slidably connected to a limiting retaining ring at the front end of the inner groove.
[0009] Furthermore, a spiral conveying blade is fixedly connected to the front side wall of the rotating ring at the front end of the rotating disk, and the outer side wall of the spiral conveying blade is slidably connected to the inner wall of the feeding cylinder.
[0010] This utility model provides an environmentally friendly inorganic thermal insulation mortar screw conveyor feeding device, which has the following beneficial effects: 1. Through a complete power chain of "drive motor → drive shaft → meshing gear → transmission gear → rotating disc gear ring", coupled with six annular equidistant connecting rods to evenly support the transmission gear, it can ensure synchronous and delay-free power transmission, balanced force without slippage, and drive the screw conveyor shaft and screw conveyor blades to achieve precise synchronous rotation. Secondly, the "internal pushing + external receiving" dual-interlocking collaborative conveying mode formed by the two, combined with the "internal and external pinching" pushing effect, greatly improves the material conveying efficiency and avoids material retention caused by excessive load on a single component. In addition, the through holes on the screw conveyor shaft blades can squeeze and disperse materials during conveying, break up small clumps and reduce the contact area between the blades and materials, reducing the probability of mortar adhesion.
[0011] 2. The "annular limiting cavity" formed by the inner groove and the limiting ring provides initial limiting for the rotating ring. Combined with the limiting groove of the subsequent rotating ring, it forms a double limiting structure, which can effectively prevent axial movement and radial offset of the rotating parts during operation, reduce frictional wear of the parts, and extend the overall service life. The combined baffle integrates the triple functions of "installation carrier - rotation support - material isolation". It not only provides a stable installation benchmark for the drive motor and prevents the motor from loosening due to vibration, but also isolates the mortar dust in the feed hopper, preventing it from invading the motor drive parts and causing wear, and ensuring the long-term stable operation of the motor. At the same time, the barrier bar at the top of the feed hopper can initially intercept and disperse the input material, breaking up large clumps in advance. Combined with the internal connection design between the feeding cylinder and the feed hopper, it ensures that the pre-treated material can enter the conveying channel without any dead corners, reducing the risk of blockage from the source.

[0016] 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. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0017] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown: This utility model provides an inorganic thermal insulation environmentally friendly mortar screw press feeding device, including: a feeding hopper 1, a feeding cylinder 102 fixedly connected to the bottom front side of the feeding hopper 1, the feeding cylinder 102 and the feeding hopper 1 being internally connected, a combined baffle 2 fixedly installed at the bottom of the rear side wall of the feeding hopper 1, a drive motor 3 fixedly installed at the middle of the rear side wall of the combined baffle 2, a rotating disk 5 rotatably connected to the front side wall of the combined baffle 2, and horizontally equidistant blocking bars 101 installed on the left and right inner walls of the top of the feeding hopper 1. A circular inner groove 103 is formed at the bottom of the rear inner wall of the feeding hopper 1, and a limit ring 10301 is fixedly installed at the front end of the inner groove 103. Specifically, the inner groove 103 and the limit ring 10301 form a matching rotation. The "annular limiting cavity" of ring 502 pre-limits the rotation trajectory of the rotating ring 502, preventing axial movement or radial offset during subsequent operation and ensuring the basic stability of the rotating components. The combined baffle 2 has a triple function of "installation carrier-support-isolation": it provides a stable installation benchmark for the drive motor 3, avoiding loosening of the installation due to motor vibration, and also serves as a rotation support seat for the rotating disk 5. At the same time, it separates the drive motor 3 from the material inside the feed hopper 1, preventing mortar dust from entering the motor drive components and causing wear, thus extending the service life of the motor. The design of the feed cylinder 102 being connected to the inside of the feed hopper 1 ensures that the material pre-treated by the baffle bar 101 can directly enter the conveying channel, avoiding the formation of dead corners for material accumulation at the connection.
[0018] In this configuration, six connecting rods 202 are installed in a ring at equal intervals in the middle of the front side wall of the combined baffle 2. A transmission gear 4 is rotatably connected to each connecting rod 202. An inner extension cylinder 201 is fixedly connected to the front end of the connecting rod 202. The inner extension cylinder 201 is located in the feed hopper 1. A gear ring is provided on the inner ring of the rotating disk 5, which meshes with the transmission gear 4 sleeved on the connecting rod 202 between the combined baffle 2 and the inner extension cylinder 201. Six connecting columns 501 are installed in a ring at equal intervals in the front side wall of the rotating disk 5. A rotating ring 502 is fixedly connected to the front end of the connecting column 501. The front end of the outer side wall of the rotating ring 502 is provided with... A limiting groove 50201 is provided, and a rotating ring 502 is rotatably connected to an inner groove 103 opened at the bottom of the rear inner wall of the feed hopper 1. The limiting groove 50201 is slidably connected to a limiting retaining ring 10301 opened at the front end of the inner groove 103. A spiral conveying blade 503 is fixedly connected to the front side wall of the rotating ring 502 at the front end of the rotating disk 5. The outer side wall of the spiral conveying blade 503 is slidably connected to the inner wall of the feeding cylinder 102. Specifically, the six annular equidistant connecting rods 202 provide evenly distributed rotational support points for the transmission gear 4, ensuring that the transmission gear 4 is balanced in force when meshing with the inner ring gear of the rotating disk 5. To prevent excessive force on a single point from causing gear wear, the inner extension cylinder 201 at the front end of the connecting rod 202 extends deep into the feed hopper 1, blocking material from entering the gap between the combined baffle 2 and the rotating disk 5. This prevents material from getting stuck at the connection of rotating parts and affecting operation. The meshing design of the inner ring gear of the rotating disk 5 and the transmission gear 4 establishes a power transmission path of "transmission gear 4 → rotating disk 5," ensuring that the rotation of the transmission gear 4 can synchronously drive the rotating disk 5, avoiding power transmission delays or slippage. The connecting column 501 securely connects the rotating disk 5 and the rotating ring 502, enabling the power of the rotating disk 5 to be synchronously transmitted to the rotating ring 502. This drives the spiral conveyor blades 503 to rotate. The rotating ring 502 forms a "double limit" on the basis of the first "inner groove 103 limit" through the sliding cooperation between the limiting groove 50201 and the limiting retaining ring 10301. This further reduces the frictional wear between the rotating ring 502 and the inner groove 103, and extends the service life of the components. The sliding contact between the outer wall of the spiral conveyor blades 503 and the inner wall of the feeding cylinder 102 can scrape off the residual material on the inner wall of the feeding cylinder 102 to the greatest extent, reducing waste. At the same time, the spiral pushing action smoothly conveys the material to the front end of the feeding cylinder 102, avoiding the formation of bridging and blockage of materials in the cylinder.
[0019] The drive shaft 301 of the drive motor 3 passes through the middle of the combined baffle 2 and the inner cylinder 201 on the front side of the combined baffle 2. The rear end of the drive shaft 301 is fixedly connected to a meshing gear 302, which meshes with the transmission gear 4 sleeved on the connecting rod 202 between the combined baffle 2 and the inner cylinder 201. The front end of the drive shaft 301 is fixedly connected to a spiral conveying shaft 303. The spiral blades of the spiral conveying shaft 303 have through holes 304. Specifically, the drive shaft 301 passes through the middle of the combined baffle 2 and the inner cylinder 201, ensuring the coaxiality of the drive shaft 301 when rotating and preventing misalignment of the meshing gear 302 and the transmission gear 4 due to shaft misalignment. At the same time, the inner cylinder 201 provides auxiliary support for the drive shaft 301, reducing the deflection deformation of the drive shaft 301 when rotating at high speed and improving the stability of power transmission. The meshing of the meshing gear 302 and the transmission gear 4 establishes the "drive motor 3 → drive..." The initial power chain of "shaft 301 → meshing gear 302 → transmission gear 4" combined with the second transmission path of "transmission gear 4 → rotating disk 5 gear ring" forms a complete power transmission system, ensuring that the screw conveyor shaft 303 and the screw conveyor blade 503 rotate synchronously. This achieves a dual-interlocking collaborative conveying of "internal pushing of the screw conveyor shaft 303 + external receiving of the screw conveyor blade 503", improving conveying efficiency and avoiding material stagnation caused by excessive load on a single component. The screw conveyor shaft 303 at the front end of the drive shaft 301 can push the material in the feeding cylinder 102 a second time, forming an "internal and external clamping" conveying with the screw conveyor blade 503, further preventing material blockage in the cylinder. The through holes 304 on the screw blades of the screw conveyor shaft 303 can squeeze and disperse the material during the conveying process, breaking up small clumps formed during material conveying, while reducing the contact area between the blades and the material, reducing the probability of mortar adhesion on the blades, and ensuring smooth blade rotation.
[0020] The specific usage and function of this embodiment are as follows: When using the inorganic thermal insulation environmentally friendly mortar screw conveyor feeding device, the inorganic thermal insulation environmentally friendly mortar to be conveyed is put into the feed hopper 1. During the material falling process, the blocking bars 101 installed horizontally at equal intervals on the left and right inner walls of the top of the feed hopper 1 will initially intercept and disperse the material, breaking up any large lumps that may be present, and avoiding blockage of the connection inlet between the feed hopper 1 and the feeding cylinder 102. Then, the drive motor 3 is started, and the motor drives the front drive shaft 301 to rotate. The meshing gear 302 at the rear end of the drive shaft 301 synchronously meshes with the transmission gear 4 on the connecting rod 202 between the transmission combination baffle 2 and the inner extension cylinder 201. The transmission gear 4 then meshes with the inner ring gear of the drive rotating disk 5, so that the rotating disk 5 rotates stably in front of the combination baffle 2. The rotating disk 5 drives the rotating ring 502 to rotate inward through the front annular equidistant connecting column 501. The material rotates smoothly within the groove 103 (relying on the double limiting of the inner groove 103 and the limiting retaining ring 10301 to prevent the rotating ring 502 from axially shifting or radially deviating), thereby driving the spiral conveying blades 503 on the front side of the rotating ring 502 to slide and push against the inner wall of the feeding cylinder 102. At the same time, the spiral conveying shaft 303 at the front end of the drive shaft 301 rotates synchronously. The material entering the feeding cylinder 102 achieves "internal and external clamping" conveying under the dual linkage and synergistic effect of receiving and pushing from the outside of the spiral conveying blades 503 and pushing from the inside of the spiral conveying shaft 303. During the conveying process, the through holes 304 on the spiral blades of the spiral conveying shaft 303 will further squeeze and disperse the material, break up the small clumps formed during the conveying process and reduce the adhesion of the material on the blades, and finally make the material stably conveyed forward along the feeding cylinder 102 to complete the entire feeding operation.
[0021] Example 2: A flexible electric heating belt is wound around the inside of the feeding cylinder 102, and the outside of the electric heating belt is wrapped with thermal insulation cotton. At the same time, two temperature sensors are embedded in the inner wall of the feeding cylinder 102 (located in the middle of the feeding cylinder 102 and the discharge end, respectively). The temperature sensors are connected to an external temperature controller via wires. The temperature controller is electrically connected to the electric heating belt and can set a temperature range. In response to the problem of decreased mortar fluidity and easy clumping in low-temperature environments, the electric heating belt can gently heat the mortar in the feeding cylinder 102, maintain the mortar in a suitable temperature range for flow, and avoid aggregate settling and fiber agglomeration due to excessively low temperature. The temperature sensors monitor the temperature at different locations inside the feeding cylinder 102 in real time, and the temperature controller automatically adjusts the power of the electric heating belt to prevent local overheating and evaporation of mortar moisture. The thermal insulation cotton reduces heat loss and improves energy efficiency, enabling the device to deliver materials stably in winter or low-temperature construction environments, thus broadening the applicable scenarios.
