Description

Technical Field

[0001] This utility model relates to the field of spreading equipment technology, and in particular to a spreading device. Background Technology

[0002] In winter, snowfall is common. Due to the low ambient temperature, the snow on the roads cannot melt in time, making the roads slippery. To quickly reduce ice and snow on the roads, de-icing agents containing chloride salts are usually spread on the road surface using de-icing devices to lower the melting point of the ice and snow, accelerate the melting of ice and snow, clear the ice and snow from the roads, improve road safety, and increase road transport efficiency.

[0003] The spreading device mainly consists of a salt tank, a conveying mechanism, and a spreading mechanism. The de-icing agent is added to the salt tank and then transported to the spreading mechanism via the conveying mechanism, where it is spread out. In existing spreading devices, the salt in the salt tank tends to clump together, preventing it from falling properly and affecting the normal conveying of the conveying mechanism. Furthermore, excessive salt weight can cause deformation of the salt tank, affecting the normal operation and service life of the spreading device. Utility Model Content

[0004] To address the aforementioned issues, this application provides a reasonably structured spreading device that reduces or even eliminates clumping without affecting the falling of the de-icing agent, effectively ensuring smooth and efficient conveying of the agent to the discharge port via the conveying auger. It also effectively enhances the structural strength of the housing and is highly practical.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A spreading device includes a box for carrying materials. A conveying auger is installed at the bottom of the box along the front-to-back direction. A discharge port is opened on the bottom surface of the box at the front of the conveying auger. A front cover is installed at the lower front part of the box, and a turntable is rotatably installed on the bottom surface of the front cover. A front inclined plate is installed below the discharge port, and the bottom end of the front inclined plate extends above the turntable. A support assembly is installed on the inner wall of the box above the conveying auger.

[0007] As a further improvement to the above technical solution:

[0008] The structure of the support assembly is as follows: it includes a support plate located at the middle cross-section of the box body, and a stop plate installed on the front and rear sides of the support plate facing the front and rear ends of the box body, respectively. The stop plate has a V-shaped cross-section with the opening facing downwards. The ends of the stop plate are fixed to the front inner wall and rear inner wall of the box body via end plates. There is a gap between the two sides of the stop plate and the left and right inner side walls of the box body. The support plates on both sides of the stop plate extend downwards to form support legs, which are fixed to the inner wall of the box body.

[0009] The front and rear sides of the support plate above the stop plate are equipped with longitudinal stiffeners facing the front and rear ends of the box body, respectively. The upper part of the support plate is equipped with transverse stiffeners facing the left and right sides of the box body. The transverse stiffeners have a downward bending structure.

[0010] The lower left and right sides of the box are designed with an inward-facing structure via side inclined plates. Support frames are symmetrically installed on the outer sides of the side inclined plates. The bottom of the support frames protrudes downward from the bottom of the box, and the spreading device is supported on the external walking and moving device by the support frames.

[0011] Vibration motors are also installed on the outer walls of the two side inclined plates, and the vibration motors are housed in the vibration motor housing.

[0012] A filter cover is installed at the opening on the top surface of the box, and the filter cover covers the box at the opening.

[0013] The conveyor motor assembly, which connects with the conveyor auger and provides conveying power, is installed inside the upper part of the front cover. The cloth discharge motor assembly is installed inside the lower part of the front cover. The output end of the cloth discharge motor assembly faces downward and is connected to the turntable for power. Multiple radially arranged teeth are installed on the top surface of the turntable.

[0014] A sealing plate is installed in the middle of the front cover behind the discharge generator assembly, and a front inclined plate extends downward from the rear into the front cover, with the front inclined plate located behind the sealing plate.

[0015] A baffle plate is installed at the lower rear end of the front cover, located below the front inclined plate. The baffle plate has an arc-shaped structure facing forward.

[0016] The front end of the conveying auger extends forward into the front cover, and observation ports are respectively opened on the left and right sides of the front cover located at the front end of the conveying auger.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In use, the de-icing agent in the box is conveyed to the discharge port by the conveying auger, and falls onto the turntable via the front inclined plate. As the turntable rotates, the de-icing agent is spread. The support component bears part of the weight of the de-icing agent above the conveying auger, while dividing the internal space of the box into vertically connected partitions. This reduces or even avoids clumping without affecting the falling of the de-icing agent, effectively ensuring that it is smoothly and continuously conveyed to the discharge port by the conveying auger. It also effectively improves the structural strength of the box and has good practicality.

[0019] This utility model also has the following advantages:

[0020] The downward-facing stop plate in the support assembly serves to bear part of the weight of the de-icing agent and to separate the upper and lower spaces inside the box. Combined with the support plate, longitudinal stiffeners, and transverse stiffeners, it effectively ensures the structural strength of the support assembly and improves the structural strength of the box, thereby reducing the deformation of the box caused by the de-icing agent compression, ensuring the normal use of the spreading device, and helping to extend its service life.

[0021] The lower sides of the box are designed as side-tilting plates, which, combined with a vibration motor, help to lift the box and ensure the smooth and reliable descent of the de-icing agent inside. Attached Figure Description

[0033] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0034] like Figure 1 , Figure 2 and Figure 3As shown, a spreading device in this embodiment includes a box 2 for carrying materials. A conveying auger 7 is installed at the bottom of the box 2 along the front-to-back direction. A discharge port 22 is opened on the bottom surface of the box 2 at the front of the conveying auger 7 in the conveying direction. A front cover 5 is installed at the lower front part of the box 2. A turntable 6 is rotatably installed on the bottom surface of the front cover 5. A front inclined plate 21 is installed below the discharge port 22. The bottom end of the front inclined plate 21 extends above the turntable 6. A support assembly 8 is installed on the inner wall surface of the box 2 above the conveying auger 7.

[0035] In actual use, the de-icing agent in the box 2 is conveyed to the discharge port 22 by the conveying auger 7, and falls onto the turntable 6 through the front inclined plate 21. The de-icing agent is spread as the turntable 6 rotates.

[0036] In this embodiment, the support component 8 bears part of the weight of the de-icing agent above the conveying auger 7, while dividing the internal space of the box 2 into vertically connected partitions. This reduces or even avoids clumping without affecting the falling of the de-icing agent, effectively ensuring that the conveying auger 7 can smoothly and easily convey the agent to the discharge port 22.

[0037] like Figure 4 As shown, the structure of the support assembly 8 is as follows: it includes a support plate 83 located at the middle cross-section of the box body 2. The front and rear sides of the support plate 83 are respectively installed with stop plates 85 facing the front and rear ends of the box body 2. The cross-section of the stop plate 85 is a V-shaped structure with the opening facing downward. The ends of the stop plate 85 are fixed to the front inner wall and rear inner wall of the box body 2 via end plates 87. There is a gap between the two sides of the stop plate 85 and the left and right inner side walls of the box body 2. The support plates 83 located on both sides of the stop plate 85 extend downward to form support legs 831, and the support legs 831 are fixed to the inner wall of the box body 2.

[0038] In this embodiment, by setting a stop plate 85 on the longitudinal direction of the box body 2 and setting the stop plate 85 as a V-shaped structure with the opening facing downward, the stop plate 85 divides the box body 2 into two spaces with connected edges above the conveying auger 7. The stop plate 85 ensures the smooth conveying of the conveying auger 7 below, and the setting of the stop plate 85 does not affect the smooth falling of the de-icing agent.

[0039] The support plate 83 located above the stop plate 85 has longitudinal stiffeners 82 installed on its front and rear sides facing the front and rear ends of the housing 2, respectively. The upper part of the support plate 83 has transverse stiffeners 81 installed on its left and right sides facing the housing 2. The transverse stiffeners 81 have a downward bending structure.

[0040] In this embodiment, the downward-facing stop plate 85 in the support assembly 8 serves to bear part of the weight of the de-icing agent and to separate the upper and lower spaces inside the box 2. Combined with the support plate 83, longitudinal stiffener 82, and transverse stiffener 81, it effectively ensures the structural strength of the support assembly 8 and improves the structural strength of the box 2, thereby reducing the deformation of the box 2 caused by the de-icing agent compression, ensuring the normal use of the spreading device, and helping to extend its service life.

[0041] In this embodiment, a central tie rod 84 is installed between the stop plate 85 and the support plate 83, and an end tie rod 86 is installed between the stop plate 85 and the inner wall of the box 2, so as to improve and protect the structural strength of the stop plate 85 and ensure the stopping and bearing functions of the stop plate 85.

[0042] The lower left and right sides of the box body 2 are set as an inward structure via the side inclined plates 20. Support frames 4 are symmetrically installed on the outer side of the side inclined plates 20. The bottom surface of the support frame 4 protrudes downward from the bottom surface of the box body 2. The spreading device is supported on the external walking and moving device by the support frame 4.

[0043] Vibration motors are also installed on the outer walls of the two side inclined plates 20, and the vibration motors are housed in the vibration motor housing 3.

[0044] In this embodiment, the lower parts of both sides of the box 2 are set as side inclined plates 20, which, together with the vibration motor, help to lift and ensure the smooth and reliable falling of the de-icing agent inside the box 2.

[0045] A filter cover 1 is installed at the opening on the top surface of the box 2, and the filter cover 1 covers the box 2 at the opening.

[0046] The conveyor motor assembly 71, which connects with the conveyor auger 7 and provides conveying power, is installed inside the upper part of the front cover 5. The cloth discharge motor assembly 60 is installed inside the lower part of the front cover 5. The output end of the cloth discharge motor assembly 60 faces downward and is connected to the turntable 6 for power. The overall layout is compact and reasonable.

[0047] like Figure 5 As shown, the top surface of the turntable 6 is equipped with multiple radially arranged teeth 62.

[0048] In this embodiment, by setting the teeth 62, as the turntable 6 rotates, the de-icing agent falling on the top surface of the turntable 6 can be evenly spread in the circumference, thereby increasing and ensuring the spreading area.

[0049] exist Figure 5 In the illustrated embodiment, the tooth 62 includes a vertical wall 621 extending upward from the top surface of the turntable 6, with the top edge of the vertical wall 621 bent and extended to form an inclined wall 622; the inclined direction of the inclined wall 622 on each tooth 62 is consistent, corresponding to the rotation direction of the turntable 6, so as to effectively ensure that the de-icing agent is evenly spread outward and downward in a circumferential manner by the rotation of the turntable 6.

[0050] A sealing plate 51 is installed in the middle of the front cover 5 behind the de-icing motor assembly 60. A front inclined plate 21 extends downward from the rear into the front cover 5. The front inclined plate 21 is located behind the sealing plate 51 to isolate the de-icing motor assembly 60 from the de-icing agent environment and ensure the reliability of the motor.

[0051] A baffle plate 61 is installed at the lower rear end of the front cover 5 located below the front inclined plate 21. The baffle plate 61 has an arc-shaped structure facing forward. The baffle plate 61 prevents the de-icing agent from being spread from the turntable 6 to the external mobile device carrying the spreading device, thereby reducing the impact on the external mobile device.

[0052] The front end of the conveying auger 7 extends forward into the front cover 5. Observation ports 50 are opened on the left and right sides of the front cover 5 located at the front end of the conveying auger 7 to facilitate observation of the falling state of the de-icing agent inside.

[0053] This invention reduces or even avoids clumping of the de-icing agent without affecting its descent, effectively ensuring smooth and unobstructed transport by the conveying auger to the discharge port, and also effectively improving the structural strength of the box, making it highly practical.

[0054] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0055] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
