Description

Technical Field

[0001] This utility model relates to the field of batching and conveying equipment technology, and in particular to a batching and lifting machine for premixed mortar. Background Technology

[0002] Currently, in the production and conveying of powdery and granular materials such as premixed mortar, equipment such as bucket elevators are used for vertical conveying. These elevators rely on the bucket structure fixed on the conveyor belt to lift the batching materials from the bottom to the high-level storage tank or mixing equipment. However, the existing elevators and supporting batching systems have obvious technical defects in practical applications.

[0003] On the one hand, in the flow control stage before the batching enters the elevator, traditional outlet adjustment devices often use one-way valves or simple baffle structures. These structures are difficult to achieve precise, synchronous, and centered opening and closing adjustments, resulting in low accuracy in controlling the conveying volume of batching when it enters the elevator hopper from the storage tank. This easily leads to fluctuations and unevenness in the batching volume, ultimately affecting the accuracy and stability of the premixed mortar formula. On the other hand, in the unloading stage after the material is conveyed to the top, because premixed mortar itself contains cement, fine sand, and other components, the material has a certain degree of adhesion. When traditional fixed hoppers tilt and unload, material residue and adhesion often occur. Especially during high-frequency cyclic operations, the residual material will gradually accumulate and clump, which not only reduces the integrity of unloading and affects the batching accuracy, but also lacks an effective buffer and guiding mechanism when the material impacts the bottom of the hopper, easily causing local wear of the hopper structure and vibration of the equipment, resulting in poor long-term operational reliability.

[0004] Therefore, this utility model proposes a batching and lifting machine for premixed mortar to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems existing in the premixed mortar batching elevator, such as low control accuracy of batching and conveying volume, difficulty in achieving synchronous centering adjustment, easy material residue in the hopper during unloading, and large unloading impact leading to equipment wear and vibration, this utility model aims to provide a batching elevator for premixed mortar with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a batching and lifting machine for premixed mortar, comprising: a machine casing, a conveyor belt disposed in the middle of the inner wall of the machine casing, a hopper structure fixedly connected to the periphery of the outer wall of the conveyor belt, and a storage box installed on the right side of the outer wall of the machine casing; a centering clamping mechanism installed at the lower end of the bottom wall of the storage box, and a discharge mechanism installed in the middle of the inner wall of the hopper structure.

[0007] The centering clamping mechanism has a structure that enables bidirectional synchronous flow adjustment, and includes a support frame, a guide rail, a drive assembly, and a baffle. The unloading mechanism has a structure that enables sliding unloading and buffering impact, and includes a hollow sliding block, a spring, a second slider, a second guide rail, and a limiting plate.

[0008] Furthermore, the support frame is fixedly connected to the bottom rear end of the outer wall of the storage box, and the upper end of the support frame is fixedly connected to the first guide rail. An electric push rod is fixedly connected to the middle of the front end of the outer wall of the support frame. A slider is fixedly connected to the output end of the electric push rod in the drive assembly. A slotted connecting block is rotatably connected to the front end of the outer wall of the slider, and two slotted connecting blocks are provided. Two baffles are provided, and the baffles are slidably fitted onto the first guide rail. The rear end of the outer wall of the slotted connecting block is fixedly connected to the baffle. The extension and retraction drive of the electric push rod causes the baffles to move relative to or away from each other simultaneously. Simultaneously, the hollow sliding block is slidably connected to the middle of the inner wall of the hopper structure, and the spring is fixedly connected to the left and right sides of the bottom wall of the hollow sliding block. A second slider is fixedly connected to the left and right sides of the front end of the hollow sliding block, and the second guide rail is fixedly connected to the left and right sides of the front end of the inner wall of the hopper structure. The second guide rail and the second slider cooperate with each other.

[0009] Preferably, the hollow sliding block has a cavity in the middle of its inner wall. The cavity is used to contain the premixed mortar ingredients during the conveying process and to pour the material out by sliding during unloading.

[0010] Preferably, the other end of the spring is fixedly connected to the inner wall of the hopper structure, and the spring is arranged symmetrically from left to right to provide cushioning when the material falls in and to maintain force balance.

[0011] Preferably, the upper and lower ends of the outer wall of the second slider are fixedly connected to limit plates, and the limit plates and the corresponding limit areas of the second guide rail form a bidirectional constraint to prevent the second slider from detaching from the second guide rail during the sliding process.

[0012] Preferably, the output end of the electric push rod extends in a vertical direction, and the vertical driving force is converted into a horizontal opening and closing action.

[0013] Preferably, the connection between the slider and the slotted connecting block is configured such that when the slider moves upward, it can drive the slotted connecting block on the left to rotate counterclockwise, and at the same time drive the slotted connecting block on the right to rotate clockwise, thereby realizing the synchronous opposing movement of the two baffles.

[0014] Preferably, the slider is configured to reciprocate in the vertical direction to cooperate with the movement of the electric push rod.

[0015] Preferably, the conveyor belt is an annular belt conveyor belt, which can drive the hopper structure to perform cyclic conveying operations inside the machine casing.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problem of insufficient control accuracy of batching and conveying volume in the prior art by setting an electric push rod to drive the slider and using a slotted connecting block for rotational connection to realize the synchronous opposing action of the two baffles at the discharge port of the storage box, thus achieving the effect of precise control of batching and conveying volume.

[0018] This invention solves the problems of material residue during unloading from the hopper and large impact and inaccurate positioning during the conveying process by setting a hollow sliding block with spring and double guide rail limit inside the hopper structure. It achieves the effects of complete material unloading, reduced residue, and ensuring force balance and accurate unloading positioning when the hollow sliding block slides back and forth.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in 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 embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0028] Example:

[0029] Please refer to Figures 1 to 6 This utility model provides a batching elevator for premixed mortar, which aims to solve the structural defects of existing batching elevators, such as insufficient quantitative control accuracy during batching and conveying, easy material residue during unloading, and large impact during conveying.

[0030] Please refer to Figure 1 and Figure 2 As shown, a batching elevator for premixed mortar includes a housing 1 and a storage box 4 fixedly connected to the right side of the outer wall of the housing 1. The housing 1 serves as the main body and protective shell of the entire elevator device, while the storage box 4 is used to temporarily store the premixed mortar batching materials to be conveyed. A conveyor belt 6 is provided in the middle of the inner wall of the housing 1, and multiple hopper structures 5 are fixedly connected around the outer wall of the conveyor belt 6. The conveyor belt 6 conveys the batching materials entering the hopper structures 5 by rotating.

[0031] A centering clamping mechanism 2 is installed at the lower end of the bottom wall of the storage box 4. The centering clamping mechanism 2 is used to precisely control the discharge amount of the storage box 4 and realize the quantitative conveying of the ingredients. The centering clamping mechanism 2 includes a support frame 201, a guide rail 202, a drive assembly 203 and a baffle 204. The support frame 201 is fixedly connected to the rear end of the bottom of the outer wall of the storage box 4. The support frame 201 serves as the component mounting platform of the centering clamping mechanism 2. The upper end of the support frame 201 is fixedly connected to the guide rail 202.

[0032] The drive assembly 203 includes an electric push rod 2031, a slider 2032, and a slotted connecting block 2033. The electric push rod 2031 is fixedly connected to the middle of the front end of the outer wall of the support frame 201. The output end of the electric push rod 2031 is fixedly connected to the slider 2032. The slider 2032 is rotatably connected to two slotted connecting blocks 2033 at the front end of the outer wall.

[0033] Two baffles 204 are provided. The baffles 204 are slidably fitted onto the guide rail 202. The rear end of the outer wall of the slotted connecting block 2033 is fixedly connected to the baffles 204. The motor inside the electric push rod 2031 drives the output end of the electric push rod 2031 to extend and retract, causing the slider 2032 to slide back and forth in the vertical direction. Then, through the rotation of the slotted connecting block 2033, the two baffles 204 move relative to each other or away from each other at the same time, so as to control the size of the feed inlet of the storage box 4. The guide rail 202 plays a limiting role for the baffles 204 to ensure the accuracy of the movement.

[0034] A discharge mechanism 3 is installed in the middle of the inner wall of the hopper structure 5. The discharge mechanism 3 is designed to transport the material in the hopper structure 5 completely and reduce residue. The discharge mechanism 3 includes a hollow sliding block 301, a spring 302, a second slider 304, a second guide rail 305 and a limiting plate 306. The hollow sliding block 301 is slidably connected to the middle of the inner wall of the hopper structure 5.

[0035] Please refer to Figure 3 and Figure 5 The hollow sliding block 301 has a cavity 303 in the middle of the inner wall. The cavity 303 is used to store the premixed mortar ingredients. The hollow sliding block 301 is fixedly connected to the left and right sides of the bottom wall by springs 302. The other end of the springs 302 is fixedly connected to the inner wall of the hopper structure 5. The springs 302 are used to connect the hollow sliding block 301 and the hopper structure 5. The symmetrical arrangement of the springs 302 can evenly absorb the impact force when the material falls into the hollow sliding block 301, avoid the local wear of the hopper structure 5 caused by unilateral force, reduce the vibration caused by material impact, and protect the inner wall of the hopper structure 5 and the conveyor belt 6.

[0036] The hollow sliding block 301 is correspondingly provided with a slider 304 fixedly connected to the left and right sides of the front end of the outer wall. The left and right sides of the front end of the inner wall of the hopper structure 5 are fixedly connected to the guide rail 305. In the assembled state, the slider 304 slides and fits in the guide rail 305. The guide rail 305 provides a fixed linear guide path and is symmetrically arranged to restrict the movement direction of the slider 304 from both sides, so as to prevent the hollow sliding block 301 from shifting its center of gravity after carrying materials or from tilting due to the impact force during unloading. This ensures that the hollow sliding block 301 can accurately slide to the unloading position every time, allowing the material to be discharged along the predetermined position. The upper and lower ends of the outer wall of the slider 304 are fixedly connected to the limiting plate 306. The limiting plate 306 prevents the slider 304 from falling off the hopper structure 5 during the sliding process. The limiting plate 306 forms a bidirectional constraint from the upper and lower ends of the slider 304, firmly locking it in the corresponding limiting area of ​​the guide rail 305, preventing the slider 304 from slipping off the guide rail 305.

[0037] As a preferred embodiment of the centering clamping mechanism 2, in order to improve structural stability and achieve precise driving, an electric push rod 2031 is fixedly connected to the middle of the front end of the outer wall of the support frame 201. The extension and retraction direction of the output end of the electric push rod 2031 is vertical. A slider 2032 is fixedly connected to the output end of the electric push rod 2031. Two slotted connecting blocks 2033 are rotatably connected to the front end of the outer wall of the slider 2032. The slider 2032 slides back and forth in the vertical direction. When the slider 2032 moves upward, it drives the left slotted connecting block 2033 to rotate counterclockwise, and at the same time drives the right slotted connecting block 2033 to rotate clockwise, so as to achieve bidirectional linkage.

[0038] To ensure the accuracy and stability of the feeding control, a baffle 204 is fixedly connected to the rear end of the outer wall of the slotted connecting block 2033, and a guide rail 202 is fixedly connected to the upper end of the support frame 201. The two baffles 204 are slidably connected on the guide rail 202, and the guide rail 202 plays a limiting role on the baffles 204 to ensure the movement accuracy of the baffles 204 during the movement process.

[0039] As a preferred embodiment of the conveying structure, the conveyor belt 6 is an annular belt conveyor belt 6, and multiple hopper structures 5 are fixedly connected around the outer wall of the conveyor belt 6. The annular belt conveyor belt 6 can drive the hopper structures 5 to rotate and convey in a circular manner in the middle of the inner wall of the casing 1.

[0040] Working principle: When the hoist is started, the premixed mortar ingredients first enter the storage box 4 on the right side of the outer wall of the machine casing 1. In order to achieve precise quantitative delivery of the ingredients, the electric push rod 2031 of the centering clamping mechanism 2 is activated. The motor inside the electric push rod 2031 drives the output end of the electric push rod 2031 to extend and retract, which drives the slider 2032 to slide back and forth in the vertical direction. Then, through the rotation of the slotted connecting block 2033 connected to the front end of the slider 2032, the two baffles 204 move relative to each other or away from each other on the guide rail 202 at the same time, which precisely controls the size of the feed inlet of the storage box 4 and realizes the control of the amount of ingredients delivered.

[0041] The ingredients enter the hopper structure 5 fixedly connected to the conveyor belt 6 from the bottom of the storage box 4. The conveyor belt 6 rotates to vertically transport the ingredients. When the hollow sliding block 301 is slidably connected to the middle of the inner wall of the hopper structure 5, the ingredients fall into the cavity 303 of the inner wall of the hollow sliding block 301. At the same time, the springs 302 on the left and right sides of the bottom wall of the hollow sliding block 301 can evenly absorb the impact force when the material falls in, reduce the vibration caused by the impact of the material, and protect the inner wall of the hopper structure 5.

[0042] When the hopper structure 5 rotates with the conveyor belt 6 to the predetermined unloading position, the hollow sliding block 301 slides along the inner wall of the hopper structure 5 under the action of external force, and the second slider 304 slides on the second guide rail 305 to achieve unloading. The second guide rail 305 provides a fixed linear guiding path, and its symmetrical arrangement on the left and right sides can restrict the movement direction of the second slider 304 from both sides, ensuring that the hollow sliding block 301 can accurately slide to the unloading position each time, allowing the material to be discharged along the predetermined position. The limiting plate 306 connected to the upper and lower ends of the outer wall of the second slider 304 forms a bidirectional constraint from the upper and lower ends of the second slider 304, preventing the second slider 304 from slipping off the second guide rail 305. Through the coordinated action of the unloading mechanism 3, this utility model realizes the complete transportation of materials in the hopper structure 5 and reduces residue.
