Description

Technical Field

[0001] The invention relates to a particle spreading device, belonging to the technical field of particle spreading. Background Art

[0002] In winter road maintenance operations, spreading salt is an important means to melt ice and snow and ensure traffic safety. However, traditional salt spreading equipment faces many challenges in practical applications. First of all, these devices often rely on complex mechanical transmission systems to achieve the transmission and spreading of salt particles, which not only increases the manufacturing cost and maintenance difficulty of the equipment, but also makes the operation process cumbersome and inefficient. In addition, due to the limitations of the mechanical structure, traditional spreading equipment is prone to uneven distribution of salt particles during the spreading process, resulting in excessive salt particles and waste in some sections of the road, while other sections may not be able to effectively melt ice and snow due to insufficient salt particles.

[0003] What is more serious is that traditional spreading equipment is prone to clogging during the spreading process, especially in low temperature and humid environments, where salt particles tend to clump, further increasing the risk of clogging. This not only affects the spreading efficiency, but may also cause road safety hazards due to uneven spreading. Summary of the invention

[0005] In order to achieve the above object, the present invention adopts the following technical solution: a particle spreading device, comprising:

[0007] A turntable, the turntable is rotatably connected to the inside of the cylinder;

[0008] A plurality of blades are distributed on the upper surface of the rotating disk in a circumferential array, each blade comprising:

[0009] A material guide sheet, wherein the material guide sheet is fixed on the turntable;

[0010] A material-shifting piece, wherein the material-shifting piece is fixed on the rotating disk, one end of the material-shifting piece is connected to one end of the material-guiding piece, the other end of the material-shifting piece extends toward the edge of the rotating disk, and the material-shifting piece is arranged in an arc shape;

[0011] Among them, a plurality of material guide pieces together enclose a material receiving cavity, and the material receiving cavity is connected with the material conveying channel. Among two adjacent blades, a material discharge channel is arranged between the material guide piece of one blade and the material shifting piece of the other blade.

[0012] Preferably, the height of the middle area of ​​the upper surface of the turntable is lower than the height of the edge area.

[0013] Preferably, the turntable is slidably connected to the inside of the cylinder through a driving assembly;

[0014] The cylinder is provided with:

[0015] An accommodating cavity, which is provided in the cylinder and located above the blades, and is used to accommodate the blades;

[0016] The baffle is rotatably connected to the cylinder body, and is used to block the lower end opening of the accommodating cavity. A through hole for the blade to pass through is opened on the surface of the baffle.

[0017] Preferably, the drive assembly comprises:

[0018] A tray, the tray is arranged in the cylinder and below the turntable;

[0019] An upper clamping plate, wherein the upper clamping plate is fixed on the lower surface of the turntable, and the lower surface of the upper clamping plate is connected to the upper surface of the tray;

[0020] A lower clamping plate, wherein the lower clamping plate is fixed to the lower surface of the upper clamping plate, and the upper surface of the lower clamping plate is connected to the lower surface of the tray;

[0021] The oil cylinder has a cylinder body fixed on the barrel, and an output shaft of the oil cylinder is connected to the tray through an ear block.

[0022] Preferably, balls rollingly connected to the tray are evenly distributed on the lower surface of the upper clamping plate and the upper surface of the lower clamping plate.

[0023] Preferably, the center of the cylinder is rotatably connected to a power rod, the turntable is sleeved on the power rod, a spline is provided on the side wall of the turntable, and a long groove cooperating with the spline is opened on the side wall of the power rod.

[0025] Preferably, a plurality of impact blocks are arranged at one end of the material-moving sheet close to the material discharging channel, each impact block is in the shape of a pyramid, and the tip of the impact block faces the material guiding direction of the adjacent material-guiding sheet.

[0026] Compared with existing technologies:

[0027] The present invention utilizes the centrifugal force generated by the rotation of the turntable to naturally guide the granular material to flow along the guide plate to the discharge channel, and can achieve effective material transmission and distribution without complex mechanical structures, simplifying the operation process and reducing maintenance costs. Secondly, the unique arc-shaped design of the material-dispensing plate not only effectively pushes the granular material to move to the edge during the rotation of the turntable, but also increases the driving force of material spreading through its extended part, ensuring that the material can be smoothly and evenly spread out from the spreading port, avoiding the blockage and unevenness problems common in traditional spreading methods.

[0028] The turntable surface of the present invention adopts a design of a low middle part and high edges, which provides an inclined upward scattering path for the granular material, which not only improves the scattering speed of the material, but also gives the material an upward scattering force, making the scattering range wider and the coverage more uniform.

[0029] The present invention allows the turntable to slide up and down in the cylinder, thereby dynamically adjusting the distance between the turntable and the baffle, thereby achieving precise control of the amount of particles to be scattered. When the turntable rises, the height of the discharge channel decreases, effectively limiting the outflow of particles. In extreme cases, when the turntable is close to the baffle, the discharge channel is completely closed, completely preventing accidental leakage of particles. On the contrary, when the turntable descends, the discharge channel is enlarged, increasing the amount of particles to be scattered, meeting the needs of different operating scenarios.

[0052] The present invention is described below with specific embodiments, but they are not intended to be limiting of the invention.

[0053] Embodiment 1

[0054] like Figure 1-Figure 12 As shown, in this embodiment, a particle spreading device is provided, including a cylinder 1, a feeding channel 101 is provided on the cylinder 1, and a spreading port 102 is opened on one side of the cylinder 1; a rotating disk 2 is rotatably connected inside the cylinder 1, and as shown in FIG. Figure 1-Figure 4 and Figure 6-Figure 7As shown, in order to drive the turntable 2 to rotate, a power rod 7 is connected to the center rotation of the cylinder 1, and the turntable 2 is sleeved on the power rod 7. A spline 201 is provided on the side wall of the turntable 2. A long groove 701 cooperating with the spline 201 is opened on the side wall of the power rod 7. The long groove 701 is opened along the length direction of the power rod 7. When the turntable 2 slides inside the cylinder 1, the spline 201 can slide in the long groove 701, and during the sliding process of the turntable 2, the cooperation between the spline 201 and the long groove 701 will not affect the normal rotation of the turntable 2 driven by the power rod 7, and then during the scattering process of the particles, the amount of the scattering particles can be adjusted in real time.

[0055] Combination Figure 1 , Figure 6 As shown, the upper and lower ends of the cylinder 1 are provided with retaining frames for supporting the power rod 7, and the two ends of the power rod 7 are installed on the cylinder 1 through the retaining frames, wherein the upper end of the power rod 7 is connected to a flange connected to an external power mechanism, and the external power mechanism can be a motor to drive the power rod 7 to rotate. In addition, the flange can also be connected to the lower end of the power rod 7.

[0056] like Figure 7 As shown, the upper end of the cylinder 1 is connected with a connector 10 , which is used to connect to a hopper containing particles, and a retaining frame at the upper end of the cylinder 1 is arranged on the connector 10 .

[0057] A plurality of blades 3 are distributed in a circular array on the upper surface of the turntable 2, and each blade 3 includes a guide piece 301 and a material-pickup piece 302, wherein the guide piece 301 is fixed on the turntable 2, the material-pickup piece 302 is fixed on the turntable 2, and one end of the material-pickup piece 302 is connected to one end of the guide piece 301, and the other end of the material-pickup piece 302 extends toward the edge of the turntable 2, and the material-pickup piece 302 is arranged in an arc shape; wherein, the plurality of guide pieces 301 together enclose a material receiving cavity, and the material receiving cavity is connected to the material conveying channel 101, and the particulate material is introduced into the interior of the device through the material conveying channel 101 on the cylinder 1, and these particles first enter the material receiving cavity enclosed by the plurality of guide pieces 301, and in two adjacent blades 3, a discharge channel is arranged between the guide piece 301 of one blade 3 and the material-pickup piece 302 of the other blade 3.

[0058] First, the granular material is introduced into the device through the feeding channel 101 on the cylinder 1. Once these particles enter the cylinder, they will first fall into the receiving cavity surrounded by a plurality of guide plates 301. The receiving cavity can accommodate and temporarily store the granular material entering from the feeding channel.

[0059] Turntable 2 Follow Figure 4The rotating disk 2 rotates in the direction of the arrow shown. The rotation of the rotating disk 2 not only drives its own movement, but also drives the granular material in the receiving cavity to rotate through friction or airflow. In this process, the centrifugal effect generated by the rotation of the rotating disk 2 causes the granular material to adhere to the guide sheet 301 after centrifugal movement, and flow along the side wall of the guide sheet 301 toward the discharge channel. At this time, the arc design of the material-dispensing sheet 302 begins to play a role. Since one end of the material-dispensing sheet 302 is connected to the guide sheet 301 and the other end extends toward the edge of the rotating disk 2, when the rotating disk 2 rotates, the material-dispensing sheet 302 can effectively push the granular material from the discharge channel position to the edge of the rotating disk 2. Finally, the material is evenly dispersed outside the device through the dispensing port 102 opened on one side of the cylinder 1, completing the entire spraying process. This spraying device not only has the characteristics of simple structure and convenient operation, but also can achieve efficient and uniform spreading of granular materials, and is suitable for a variety of scenes where granular materials need to be spread.

[0060] In addition, when the guide piece 301 guides the particles in the material receiving cavity to the discharge channel, the particles will face the side wall of the material stripping piece 302 from the discharge direction of the discharge channel, and the particles will collide with the side wall of the material stripping piece 302. The impact can break large particles, which is conducive to uniform spreading.

[0061] The height of the middle area of ​​the upper surface of the turntable 2 is lower than that of the edge area. Since the upper surface of the turntable 2 is designed to be low in the middle and high at the edge, the spreading effect of the granular material is further enhanced. When the granular material is pushed to the edge of the turntable by the material-selecting piece 302, they will move in the upward direction along the upper surface of the turntable 2. This upward slanting motion trajectory makes the granular material have not only a horizontal speed but also an upward slanting speed at the moment of being spread out from the spreading port 102. This composite speed enables the granular material to be spread over a longer distance and cover a wider area.

[0062] Embodiment 2

[0063] like Figure 7-Figure 9 As shown, on the basis of the first embodiment, in order to adjust the size of the material spreading port 102 and thus adjust the amount of particles to be scattered, the turntable 2 is slidably connected to the inside of the cylinder 1 through the driving assembly 6; the cylinder 1 is provided with a receiving chamber 4 for accommodating the blades 3, the receiving chamber 4 is annular, the center of the receiving chamber 4 coincides with the center of the feeding channel 101, the bottom of the receiving chamber 4 is rotatably connected with a baffle 5, the upper end of the blade 3 passes through the through hole provided on the baffle 5 and extends to the inside of the receiving chamber 4, as shown in FIG. Fig. 9 As shown, in order to enable the baffle plate 5 to rotate smoothly and be connected in the cylinder body 1, bearings 8 are sleeved on the outer wall and the inner wall of the baffle plate 5. Fig. 9As shown, in order to facilitate the installation of the baffle plate 5, the cylinder 1 is divided into an upper and a lower part. A groove for installing the bearing 8 is provided at the connection between the upper and lower parts of the cylinder 1, and the baffle plate 5 is installed at the connection between the upper and lower parts of the cylinder 1 through the bearing 8.

[0064] When the turntable 2 rotates, the particles in the receiving cavity are scattered from between the turntable 2 and the baffle 5. Driven by the driving assembly 6, the turntable 2 can slide up and down inside the cylinder 1.

[0065] When the turntable 2 slides upward, the turntable 2 slides upward with the blades 3, and the distance between the turntable 2 and the baffle 5 gradually decreases, so that the upper end of the blade 3 passes through the through hole of the baffle 5 and slides into the interior of the accommodating cavity 4, and the upper and lower heights of the discharge channel become smaller, so that the amount of scattered particles can be reduced, and when the turntable 2 slides upward to fit with the baffle 5 (such as Figure 6 As shown in the figure, the blade 3 is completely received in the accommodating chamber 4, and the discharge channel is closed at this time, so that when the scattering of particles stops, the particles can be prevented from leaking out of the scattering port.

[0066] When the turntable 2 slides downward, the turntable 2 slides downward with the blades 3, the distance between the turntable 2 and the baffle 5 gradually decreases, the upper end of the blade 3 gradually slides out of the accommodating cavity 4, and the upper and lower heights of the discharge channel increase, so that the amount of scattered particles can be increased.

[0067] like Fig.10 As shown, in order to drive the turntable 2 to slide up and down inside the cylinder 1, the driving assembly 6 includes a tray 601, an upper clamping plate 602 and a lower clamping plate 603. The tray 601 is arranged in the cylinder 1 and is located below the turntable 2; the upper clamping plate 602 is fixed on the lower surface of the turntable 2, and the lower surface of the upper clamping plate 602 is connected to the upper surface of the tray 601; the lower clamping plate 603 is fixed on the lower surface of the upper clamping plate 602, and the upper surface of the lower clamping plate 603 is connected to the lower surface of the tray 601; an oil cylinder 604 is fixedly installed on the cylinder 1, and the output shaft of the oil cylinder 604 is connected to the tray 601 through an ear block.

[0068] The upper clamping plate 602, the lower clamping plate 603 and the tray 601 are all ring-shaped. When the upper clamping plate 602 and the lower clamping plate 603 are fixed together by bolts, an annular groove for clamping the tray 601 is formed between the upper clamping plate 602 and the lower clamping plate 603, and the tray 601 is placed in the annular groove. When the output shaft of the cylinder 604 is extended, the tray 601 is pushed to move upward through the ear block. At this time, the tray 601 uses the upper clamping plate 602 and the lower clamping plate 603 to drive the turntable 2 to move upward. Conversely, when the output shaft of the cylinder 604 is extended, the tray 601 drives the turntable 2 to move downward, and the upper clamping plate 602 and the lower clamping plate 603 can rotate synchronously with the turntable 2, so that the process of the drive component 6 driving the turntable 2 to slide will not interfere with the rotation of the turntable 2.

[0069] Balls 605 that are rollingly connected to the tray 601 are evenly distributed on the lower surface of the upper clamping plate 602 and the upper surface of the lower clamping plate 603 .

[0070] Since the tray 601 is rollingly connected to the upper and lower plates 602 and 603 through the ball bearings 605 , friction is reduced, so that when the turntable 2 rotates with the upper and lower plates 602 and 603 , the upper and lower plates 602 and 603 can move smoothly on the tray 601 through the ball bearings 605 .

[0071] Embodiment 3

[0072] like Figure 11-Figure 12 As shown, in the above embodiment, in order to be able to crush large particles and prevent large particles from being unable to pass through the discharge channel and accumulating in the receiving cavity, a plurality of impact blocks 9 are arranged at one end of the material removal piece 302 close to the discharge channel. Each impact block 9 is in the shape of a pyramid, and the tip of the impact block 9 is facing the guiding direction of the adjacent guide piece 301.

[0073] When the guide sheet 301 encounters larger particles during the material guiding process, these particles will contact the impact block 9 arranged at one end of the material removal sheet 302 near the discharge channel when moving along the material guiding direction of the guide sheet 301. The pyramidal design of the impact block 9 allows its tip to directly contact the large particles.

[0074] When large particles of material hit the tip of the impact block 9, due to the hardness and sharp shape of the impact block 9, sufficient impact force is generated to break the large particles into smaller particles. These smaller particles can then continue to move along the discharge channel and eventually be scattered through the spreading port 102. The impact can break the large particles, which is conducive to uniform spreading.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
