Description

Technical Field

[0001] This utility model belongs to the field of bamboo shoot grading technology, and in particular relates to a bamboo shoot coarse and fine grading machine. Background Technology

[0002] Bamboo shoot grading is a process of classifying bamboo shoots into different grades based on their physical characteristics or intrinsic quality, using mechanical equipment or manual methods. Grading enables the standardization and improvement of bamboo shoot products, and different grades of bamboo shoots can meet differentiated market demands.

[0003] Currently, existing bamboo shoot coarse and fine grading machines typically involve placing bamboo shoots onto the grading machine for grading. However, these machines lack proper collection capabilities and do not allow for simultaneous weighing of the graded bamboo shoots during collection. Consequently, they cannot effectively calculate the weight percentage of each grade in each batch of bamboo shoots, resulting in certain limitations in their use.

[0004] Therefore, we propose a bamboo shoot coarse and fine grading machine to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problems of poor collection and weighing of green bamboo shoots in the existing technology, and to propose a green bamboo shoot coarse and fine grading machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bamboo shoot coarse and fine grading machine includes a base frame. Two fixed plates are fixedly connected to the upper surface of the base frame. A limit frame is fixedly connected to one side of the two fixed plates that are close to each other. The outer surface of the limit frame is fixedly connected to the outer surface of the base frame. Three display screens are fixedly connected to the left side of the limit frame. A controller is fixedly connected to the front of the limit frame. Three collection frames are slidably connected to the inner wall of the limit frame. Three pressure sensors are fixedly connected to the inner bottom wall of the limit frame. The bottom surface of each collection frame is in contact with the upper surface of the pressure sensor. A support frame is fixedly connected to one side of the two fixed plates that are close to each other. Several conveying rollers are rotatably connected to the inner wall of the support frame. Each display screen and each pressure sensor is electrically connected to the controller via wires.

[0008] Preferably, two positioning blocks are fixedly connected to both the front and back of the base frame, and each positioning block has a positioning hole on its upper surface.

[0009] Preferably, a grading frame is provided above the base frame, and a vibration motor is fixedly connected to both the front and back of the grading frame.

[0010] Preferably, the bottom surface of the grading frame is fixedly connected to two sets of strong springs, and the bottom end of each set of strong springs is fixedly connected to the top end of the base frame.

[0011] Preferably, the inner wall of the grading frame is fixedly connected with four grading columns, and the outer surface of each grading column is fixedly connected with a baffle, and the back of each baffle is fixedly connected to the front of the grading frame.

[0012] Preferably, six drainage blocks are fixedly connected to the upper surface of the support frame, wherein the sides of two drainage blocks that are far apart from each other are fixedly connected to the sides of two fixing plates that are close to each other.

[0013] Preferably, four fixing blocks are fixedly connected to the upper surface of each collection box, and a pull ring is rotatably connected to the inner wall of each fixing block.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] By setting up limit frames, the limit frames and collection frames form an orderly collection system. After the bamboo shoots are graded by coarseness and conveyed by the conveyor rollers, they can fall directly into the corresponding collection frames, avoiding the scattered accumulation of bamboo shoots after grading, improving collection efficiency and site cleanliness. At the same time, the bottom of the collection frames is in contact with pressure sensors, which can sense the weight of the bamboo shoots in real time. The data is transmitted to the controller through wires and displayed intuitively on the screen, realizing the synchronous operation of grading and weighing. This design can accurately calculate the weight ratio of different grades in each batch of bamboo shoots. For example, during the grading process, the operator can view the weight data of bamboo shoots in each collection frame in real time, which makes it easy to quickly grasp the production distribution of bamboo shoots of different coarseness grades, providing data support for subsequent sales pricing, processing allocation, etc. Compared with traditional grading machines, this device realizes the integrated operation of grading-collection-weighing through structural integration, which not only reduces the manual transfer links and reduces labor intensity, but also avoids damage to bamboo shoots caused by secondary handling, ensuring product quality.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A bamboo shoot coarse and fine grading machine includes a base frame 1. Two fixing plates 2 are fixedly connected to the upper surface of the base frame 1. A limit frame 3 is fixedly connected to one side of the two fixing plates 2 that are close to each other. Two positioning blocks 8 are fixedly connected to the front and back of the base frame 1. Each positioning block 8 has a positioning hole 9 on its upper surface. The positioning block 8 is made of high-strength alloy steel and is firmly fixed to the surface of the base frame 1 by welding. Its structure is designed as a cuboid shape with a moderate height, which can ensure the stability of positioning without interfering with the overall layout of the grading machine. The diameter of the positioning hole 9 is precisely machined according to the specifications of common fixing bolts, and the hole wall is finely ground to ensure that when the bolt is passed through the positioning hole 9 to fix the grading machine on the ground or other supporting plane, it can fit tightly and prevent the grading machine from shifting due to vibration or other factors during operation.

[0023] The outer surface of the limiting frame 3 is fixedly connected to the outer surface of the base frame 1. Three displays 13 are fixedly connected to the left side of the limiting frame 3. A grading frame 4 is set on the top of the base frame 1. Vibration motors 5 are fixedly connected to the front and back of the grading frame 4. The grading frame 4 is a rectangular frame structure made of stainless steel, which has good corrosion resistance and strength and can adapt to complex working environments such as moisture and juice residue during the grading of bamboo shoots. The vibration motor 5 is a model specially designed for industrial vibration equipment. When the vibration motor 5 is working, it can generate high-frequency vibration, which causes the bamboo shoots in the grading frame 4 to move in an orderly manner along the gaps between the grading columns 6 under the action of vibration, thereby realizing the function of preliminary screening and grading of bamboo shoots according to their thickness.

[0024] A controller 11 is fixedly connected to the front of the limiting frame 3. Three collection frames 12 are slidably connected to the inner wall of the limiting frame 3. Two sets of strong springs 10 are fixedly connected to the bottom surface of the grading frame 4. The bottom end of each set of strong springs 10 is fixedly connected to the top end of the base frame 1. The strong springs 10 are made of high elasticity alloy material, have a large elastic coefficient and good fatigue life, and can withstand the large impact force generated by the grading frame 4 during vibration. Each set of strong springs 10 is composed of multiple spring units connected in series to enhance the overall elasticity and load-bearing capacity. The top end of the strong springs 10 is firmly fixed to the bottom surface of the grading frame 4 by welding or bolt connection, and the bottom end is connected by a fixing seat pre-embedded in the top end of the base frame 1.

[0025] Three pressure sensors 19 are fixedly connected to the inner bottom wall of the limiting frame 3. The bottom surface of each collection frame 12 is in contact with the upper surface of the pressure sensor 19. Four grading columns 6 are fixedly connected to the inner wall of the grading frame 4. A baffle 7 is fixedly connected to the outer surface of each grading column 6. The back of each baffle 7 is fixedly connected to the front of the grading frame 4. The grading column 6 is a cylindrical structure, and its material is the same as that of the grading frame 4, which is stainless steel. The surface is polished to be smooth and flat to reduce the frictional resistance between the bamboo shoots and the grading column 6 during the grading process and to avoid damage to the bamboo shoot skin. The four grading columns 6 are symmetrically distributed on the inner wall of the grading frame 4. Furthermore, the two ends of the grading column 6 have different thicknesses and a certain slope. The spacing between adjacent grading columns 6 is precisely set according to the different thicknesses of the bamboo shoots, thereby achieving effective grading of the bamboo shoots by thickness. The baffle 7 is a rectangular plate structure, made of the same stainless steel as the grading frame 4 and the grading column 6. It is fixed at one end to the outer surface of the grading column 6 and at the other end to the front of the grading frame 4 through a welding process, forming a stable support structure. The main function of the baffle 7 is to restrict the movement trajectory of the bamboo shoots within the grading frame 4, prevent the bamboo shoots from jumping out of the grading area during vibration, and ensure that the bamboo shoots can be graded and screened according to the predetermined path.

[0026] Two fixed plates 2 are fixedly connected to a support frame 14 on their sides that are close to each other. Several conveying rollers 15 are rotatably connected to the inner wall of the support frame 14. Six guide blocks 16 are fixedly connected to the upper surface of the support frame 14. The sides of two guide blocks 16 that are far apart from each other are fixedly connected to the sides of the two fixed plates 2 that are close to each other. The guide blocks 16 have good wear resistance and low friction coefficient, and can effectively guide the graded bamboo shoots smoothly from the grading frame 4 into the conveying rollers 15 inside the support frame 14. The six guide blocks 16 are evenly distributed on the upper surface of the support frame 14.

[0027] Each display screen 13 and each pressure sensor 19 are electrically connected to the controller 11 via wires. Four fixing blocks 17 are fixedly connected to the upper surface of each collection frame 12. Each fixing block 17 has a pull ring 18 rotatably connected to its inner wall. The fixing blocks 17 are block-shaped structures made of metal and are firmly fixed to the upper surface of the collection frame 12 by welding or bolting. Each fixing block 17 has a smooth shaft hole machined on its inner wall. The pull ring 18 is installed in the shaft hole through a rotating shaft, allowing the pull ring 18 to rotate flexibly within the fixing block 17. The pull ring 18 has a circular design and is made of the same material as the fixing block 17. Its surface is treated with rust prevention. The main function of the pull ring 18 is to facilitate the operator to easily pull the collection frame 12 out of the limit frame 3 for handling and unloading when the collection frame 12 is full of graded bamboo shoots.

[0028] The working principle of this utility model is as follows: In use, the operator first connects the vibration motor 5, controller 11, display screen 13, and pressure sensor 19 to the power supply, ensuring a stable power supply. Then, the vibration motor 5, controller 11, display screen 13, and pressure sensor 19 are turned on. The bamboo shoots are then conveyed to the grading frame 4 via the bamboo shoot conveying device. Because the guide blocks on the grading frame 4 allow the bamboo shoots to enter vertically between the baffles 7, the vibration motor 5 starts, and the grading frame 4 has a certain slope. Then, the bamboo shoots vibrate and... Under the influence of the slope, the bamboo shoots gradually move downwards, and the gaps between the grading columns 6 gradually widen. The thinner bamboo shoots will fall down along the gaps between the grading columns 6 first, while the thicker bamboo shoots will move a little before falling down. After being graded, the bamboo shoots will fall onto the support frame 14. The support frame 14 contains many conveyor rollers 15. The conveyor rollers 15 rotate, and their surfaces carry the bamboo shoots forward. There are also six guide blocks 16 on the support frame 14 to prevent the bamboo shoots from running around. The bamboo shoots continue to move forward along the conveyor rollers 15 until they reach the limit frame 3 and the receiving area. Inside the collection frame 12, there are three collection boxes 12 within the limiting frame 3. Each collection box 12 has a pressure sensor 19 underneath. Bamboo shoots of different thicknesses fall into their respective collection boxes 12. The pressure sensor 19 is a device that converts pressure signals into measurable, transmissible, and processable electrical signals or other forms of signals. Its core function is to sense external pressure and convert it into a signal output that is easy to analyze and apply. The main function of the controller 11 is to receive signals from the sensors, process these signals to better understand and analyze them, and then generate control commands based on the received signals and preset control rules to facilitate control operations. As soon as a bamboo shoot falls into a collection box 12, the pressure sensor 19 can sense the pressure change and transmit the signal to the controller 11 through a wire. After receiving the signal, the controller 11 processes it and converts it into weight data, and then transmits the information to the three displays 13 on the left side of the limiting frame 3. The displays 13 will then display the weight data of the bamboo shoot in each collection box 12 for easy viewing.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
