Description

Technical Field

[0001] This utility model belongs to the field of fertilizer processing technology, specifically, it relates to a belt-type quantitative weighing feeder. Background Technology

[0002] When loading or moving bulk materials, belt conveyors are usually needed to reduce the labor intensity of manual labor and improve the efficiency of bulk material transfer.

[0003] Existing belt conveyors include a conveyor support, a conveyor belt, and a conveyor motor. The conveyor belt is rotatably mounted on the conveyor support, and the conveyor motor is fixed on the conveyor support and is used to drive the conveyor belt to rotate. In use, bulk materials are poured onto the conveyor belt, and the conveyor motor drives the conveyor belt to rotate. The conveyor belt transports the bulk materials during rotation to achieve rapid transfer of bulk materials.

[0004] A search revealed a mobile high-precision intelligent belt quantitative feeder in document CN223149550U, relating to the technical field of belt conveyors. The feeder includes a conveyor support, a conveyor belt, and a weighing assembly. The conveyor belt is rotatably mounted on the conveyor support. The weighing assembly includes a weighing roller, a weighing sensor, a speed sensor, a controller, and a digital display. The weighing roller is located inside and in contact with the conveyor belt. The weighing sensor is connected to the weighing roller and the conveyor support and outputs a weight signal. The speed sensor is located inside the conveyor belt and outputs a speed signal. The controller is electrically connected to the weighing sensor, the speed sensor, and the digital display, responding to the weight and speed signals and controlling the digital display to display the weight value in real time. This application effectively measures the weight of bulk materials during conveyor belt transport.

[0005] The aforementioned device weighs materials through internal components during material transportation to achieve accurate measurement of bulk materials. However, when materials accumulate in one place, they may be dumped out all at once during final transportation, causing scattering and other technical problems associated with conventional one-time material discharge, which pollutes the production environment.

[0006] In view of this, this utility model is proposed. Utility Model Content

The mounting bases are symmetrically arranged on the conveyor belt, the assembly ends are locked to the corresponding mounting bases, the locking blocks are rotatably arranged on the corresponding assembly ends, the limiting plates are arranged between the assembly ends, and the limiting plates and locking blocks are driven together.

[0008] In a preferred embodiment of this utility model, each assembly end is rotatably connected to a knob, and a snap-fit ​​block is arranged around the corresponding knob, with each snap-fit ​​block being fixedly connected to the corresponding knob.

[0009] In a preferred embodiment of this utility model, each assembly end is provided with a movable frame, each movable frame is slidably connected to the corresponding assembly end, each movable frame is provided with a snap-fit ​​groove, and each snap-fit ​​block snaps into the corresponding snap-fit ​​groove.

[0010] In a preferred embodiment of this utility model, the limiting plate is arranged between the corresponding movable frames, and the limiting plate and the corresponding movable frame are connected by fasteners. Comb blocks are arranged in an array inside the limiting plate, and each comb block is slidably connected to the corresponding position of the limiting plate.

[0011] In a preferred embodiment of the present invention, an inclined groove is provided on the assembly end, a sliding block is slidably connected in the inclined groove, a second spring is provided between the sliding block and the inclined groove, and the ends of the second spring are fixedly connected to the corresponding sliding block and the inclined groove respectively.

[0012] In a preferred embodiment of this utility model, a limiting rod is provided on the sliding block, the limiting rod is connected to the sliding block by a thread, and the limiting rod abuts against the corresponding snap-fit ​​block.

[0013] In a preferred embodiment of this utility model, the mounting base is fixedly connected to the corresponding position of the conveyor belt, and a plug rod is slidably connected inside the mounting base. The plug rod is elastically set with the mounting base, and the bottom of the assembly end is plugged into the mounting base.

[0014] In a preferred embodiment of this utility model, the insertion rod is snapped into the assembly end, and a first spring is sleeved on the insertion rod. The ends of the first spring are fixedly connected to the corresponding mounting base and the insertion rod, respectively.

[0015] Compared with the prior art, the present invention has the following advantages: 1. This belt-type quantitative weighing feeder changes the height of the limiting plate by rotating the clamping block, thereby changing the thickness of the material that can be transported. This avoids common technical problems of conventional one-time discharge, such as raw materials being dumped out at once due to accumulation and causing scattering, and reduces pollution to the production environment.

[0016] 2. In this belt-type quantitative weighing feeder, the comb blocks are always hanging down under the action of gravity. The hanging comb blocks contact the conveying surface of the conveyor belt.

[0017] 3. In this belt-type quantitative weighing feeder, the limiting rod abuts against the corresponding locking block to restrict the position of the locking block, preventing the locking block from being driven to move in the opposite direction under the gravity of the movable frame and related components, thus causing the position of the limiting plate to drop.

[0018] 4. This belt-type quantitative weighing feeder, through the detachable design of its internal components, enables the disassembly, replacement, or storage of internal parts.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0023] Please see Figure 1-5 A belt-type quantitative weighing feeder includes a leveling component for leveling raw materials. The leveling component includes a conveyor belt 1, a mounting base 2, an assembly end 3, a limiting plate 41, and a snap-fit ​​block 5. The mounting base 2 is symmetrically arranged on the conveyor belt 1. The assembly end 3 is snap-fitted to the corresponding mounting base 2. The snap-fit ​​block 5 is rotatably arranged on the corresponding assembly end 3. The limiting plate 41 is arranged between the assembly ends 3. The limiting plate 41 and the snap-fit ​​block 5 are driven together. In practical use, when materials are transported by conveyor belt 1, after passing the bottom of the limiting plate 41, the limiting plate 41 blocks the materials to achieve the flattening operation. The height of the limiting plate 41 can be changed by rotating the snap-fit ​​block 5, so as to meet the different material thickness requirements. This avoids the common technical problems of one-time material discharge, such as the material being dumped out at one time due to accumulation, and reduces pollution to the production environment. Common technical issues related to single-discharge include, but are not limited to, the following: 1. One-time discharge causes material to splash, and the material falling to the ground causes unnecessary waste and damage, and also requires manual cleaning.

[0024] 2. The simultaneous release of large quantities of powdery materials such as starch, coal powder, and metal powder can instantly create a dust cloud with extremely high concentrations. If it encounters an ignition source such as static electricity, sparks, or open flames, it can easily trigger a violent dust explosion, causing devastating consequences. 3. The dust released instantly will be inhaled in large quantities by operators, which can lead to serious occupational health problems such as pneumoconiosis in the long run.

[0025] It is worth noting that the conveyor belt 1 includes a conveyor support, a conveyor belt, and a weighing assembly. The conveyor belt is rotatably mounted on the conveyor support. The weighing assembly includes a weighing roller, a weighing sensor, a speed sensor, a controller, and a digital display dial. The weighing roller is located inside the conveyor belt and abuts against it. The weighing sensor is connected to the weighing roller and the conveyor support and is used to output a weight signal. The speed sensor is located inside the conveyor belt and is used to output a speed signal. The controller is electrically connected to the weighing sensor, the speed sensor, and the digital display dial. The controller responds to the weight signal and the speed signal and is used to control the digital display dial to display the weight value in real time. The above application has the effect of accurately measuring the weight of bulk material transfer during the conveyor belt conveying process. The conveyor belt 1 has already been disclosed in the prior art of a mobile high-precision intelligent belt quantitative feeder CN223149550U, and will not be described in detail here.

[0026] Each assembly end 3 is rotatably connected to a knob 51, and a snap-fit ​​block 5 is arranged around the corresponding knob 51. Each snap-fit ​​block 5 is fixedly connected to the corresponding knob 51. Each assembly end 3 is provided with a movable frame 4, and each movable frame 4 is slidably connected to the corresponding assembly end 3. Each movable frame 4 is provided with a snap-fit ​​groove 43, and each snap-fit ​​block 5 snaps into the corresponding snap-fit ​​groove 43. A limiting plate 41 is arranged between the corresponding movable frames 4, and the limiting plate 41 is connected to the corresponding movable frame 4 by fasteners. Comb blocks 42 are arranged in an array inside the limiting plate 41, and each comb block 42 is slidably connected to the corresponding position of the limiting plate 41. Before starting work, the thickness that can be carried during transportation is determined according to the type of raw material being transported. Then, the knob 51 is manually turned. As the knob 51 is turned, it causes the locking block 5 to intermittently engage with the locking groove 43 on the movable frame 4. During engagement, the movable frame 4 is lifted upwards to a suitable height, thus limiting the thickness of the raw material transported by the conveyor belt 1 and avoiding the common technical problem of raw material accumulation and one-time discharge. The types of technical problems have been classified and summarized in detail above. See above for details. During the lifting and lowering of the limiting plate 41, the comb block 42 inside the limiting plate 41 slides out of the limiting plate 41. The comb block 42 is always hanging down under the action of gravity. The hanging comb block 42 contacts the conveying surface of the conveyor belt 1. Through the array setting of the comb block 42, the thickness of the raw material is limited and flattened, while the raw material is combed, so that the thickness of the raw material is uniform and neat, which facilitates the subsequent discharge. Fasteners include, but are not limited to, bolts.

[0027] An inclined groove is provided on the assembly end 3, and a sliding block 61 is slidably connected in the inclined groove. A second spring 62 is provided between the sliding block 61 and the inclined groove. The ends of the second spring 62 are fixedly connected to the corresponding sliding block 61 and the inclined groove respectively. A limit rod 6 is provided on the sliding block 61. The limit rod 6 is connected to the sliding block 61 by a thread, and the limit rod 6 abuts against the corresponding snap-fit ​​block 5. During the process of rotating the knob 51 to drive the locking block 5, the corresponding locking block 5 pushes the limiting rod 6 from the end of the limiting rod 6 away from the second spring 62. The limiting rod 6 is pushed by the locking block 5 and drives the sliding block 61. The sliding block 61 compresses the second spring 62, and the second spring 62 deforms. After the locking block 5 pushes the limiting rod 6 to the bottom, the locking block 5 and the limiting rod 6 separate. Then the locking block 5 intermittently engages with the locking groove 43, lifting the movable frame 4 upward. When the movable frame 4 is lifted, the limiting rod 6 resets under the deformation force of the second spring 62. Then the limiting rod 6 abuts against the corresponding locking block 5, restricting the position of the locking block 5, and preventing the locking block 5 from being driven to move in the opposite direction due to the gravity of the movable frame 4 and related components of the movable frame 4, causing the position of the limiting plate 41 to drop. If the position of the limiting plate 41 needs to be reset, the limiting rod 6 is rotated manually. The limiting rod 6 is separated from the sliding block 61 by the thread, releasing the position restriction on the locking block 5, so that the movable frame 4 can be directly reset to the initial position under the action of gravity.

[0028] The mounting base 2 is fixedly connected to the corresponding position of the conveyor belt 1. The mounting base 2 is slidably connected with the insertion rod 21. The insertion rod 21 is elastically set with the mounting base 2, and the bottom of the assembly end 3 is inserted into the mounting base 2. The insertion rod 21 is snapped into the assembly end 3. A first spring 22 is sleeved on the insertion rod 21. The end of the first spring 22 is fixedly connected to the corresponding mounting base 2 and the insertion rod 21 respectively. When the insertion rod 21 is pulled manually, it compresses the first spring 22. The first spring 22 deforms and applies the deformation force to the insertion rod 21. The assembly end 3 is placed in the mounting base 2 and engages with the inner wall of the mounting base 2. Then, the force on the insertion rod 21 is released, and the deformation force of the first spring 22 pushes the insertion rod 21 to engage with the bottom of the assembly end 3, thus achieving quick installation of the assembly end 3. When the assembly end 3 needs to be disassembled, the insertion rod 21 is pulled to separate it from the assembly end 3, and the assembly end 3 can be removed from it.

[0029] Working Principle: In actual use, when materials are transported by conveyor belt 1, after passing the bottom of the limiting plate 41, the limiting plate 41 blocks and flattens the materials. The height of the limiting plate 41 can be changed by rotating the locking block 5, thus adapting to the required transport thickness of different materials. This avoids common problems with one-time material discharge, such as spillage due to accumulation, reducing pollution to the production environment. Before operation, the transport thickness is determined based on the type of raw material. Then, the knob 51 is manually rotated. Rotating the knob 51 causes the locking block 5 to intermittently engage with the locking slot 43 on the movable frame 4, thus securing the materials. The movable frame 4 is lifted upwards to a suitable height, limiting the thickness of the raw material transported by the conveyor belt 1 to avoid material accumulation and the common technical problem of one-time discharge. This type of technical problem has been categorized and summarized in detail above. During the lifting and lowering of the limiting plate 41, the comb blocks 42 inside the limiting plate 41 slide out of the limiting plate 41. The comb blocks 42, under the influence of gravity, always hang downwards, contacting the conveying surface of the conveyor belt 1. Through the array of comb blocks 42, the thickness of the raw material is limited and flattened, while simultaneously combing the material to make its thickness uniform and neat, facilitating subsequent discharge. During the rotation of the knob 51, which drives the locking block 5, the corresponding locking block 5 moves from... The end of the limiting rod 6 furthest from the second spring 62 pushes the limiting rod 6. The limiting rod 6 is pushed by the locking block 5 and drives the sliding block 61. The sliding block 61 compresses the second spring 62, and the second spring 62 deforms. After the locking block 5 pushes the limiting rod 6 to the bottom, the locking block 5 separates from the limiting rod 6. Then the locking block 5 intermittently engages with the locking groove 43, lifting the movable frame 4 upward. When the movable frame 4 is lifted, the limiting rod 6 returns to its original position under the deformation force of the second spring 62. Then the limiting rod 6 abuts against the corresponding locking block 5, restricting the position of the locking block 5 and preventing the locking block 5 from being driven to move in the opposite direction due to the gravity of the movable frame 4 and related components, causing the position of the limiting plate 41 to drop. If it is necessary to adjust the position of the limiting plate 4... To reset position 1, manually rotate the limiting rod 6. The limiting rod 6 separates from the sliding block 61 through the thread, releasing the position restriction on the locking block 5. This allows the movable frame 4 to directly reset to its initial position under gravity. Manually pull the insertion rod 21, which compresses the first spring 22. The first spring 22 deforms and applies the deformation force to the insertion rod 21. The assembly end 3 is placed inside the mounting base 2 and engages with the inner wall of the mounting base 2. Then, release the force on the insertion rod 21. The deformation force of the first spring 22 pushes the insertion rod 21 to engage with the bottom of the assembly end 3, enabling quick installation of the assembly end 3. When the assembly end 3 needs to be disassembled, pull the insertion rod 21 to separate it from the assembly end 3, and remove the assembly end 3.
