Description

Technical Field

[0001] This utility model belongs to the field of dryer screen beds, and specifically relates to a dryer screen bed unit component. Background Technology

[0002] The dryer screen is a crucial component inside the dryer. It is usually a plate-shaped or belt-like structure with many small holes. Its main functions are twofold: first, to support the material to be dried (such as grains, seeds, etc.); and second, to allow hot air to pass evenly through the material layer, thereby achieving efficient and uniform drying.

[0003] The mobile screen bed itself is a slowly moving conveyor belt. Material enters from the feed end and is transported to the discharge end as the conveyor belt moves, completing the drying process in the process. The structure of the dryer screen bed includes two sets of parallel sprocket and chain assemblies. Between the two sets of sprocket and chain assemblies are several screen plates arranged sequentially along the length direction. In order to prevent material from falling from the left and right sides of the screen plates, baffles are usually installed on both sides of the screen plates to block the material. The disadvantage is that, due to structural design issues, material can still fall from the sides of the screen plates and into the gaps between adjacent screen plates. Utility Model Content

[0004] The purpose of this invention is to provide a dryer screen bed unit assembly that can prevent materials from falling off the screen plate and ensure normal material conveying.

[0005] The purpose of this utility model is achieved as follows: A dryer screen bed unit assembly includes two sets of parallel sprocket and chain assemblies. Between the two sets of sprocket and chain assemblies, there are several screen plates arranged sequentially along the length direction. The front side of each screen plate is provided with an overlapping part one, and the rear side of each screen plate is provided with an overlapping part two. The overlapping part one of each screen plate overlaps the adjacent screen plate and correspondingly blocks the overlapping part two of the adjacent screen plate. Each screen plate has a baffle plate vertically arranged on its left and right sides. The baffle plate has an installation groove corresponding to the overlapping part one, and the overlapping part one fits into the installation groove of the upper baffle plate.

[0006] In this invention, the screen plates are interconnected via overlapping portions one and two. Overlap portion one protrudes upwards, forming a space below it to accommodate overlapping portions two of adjacent screen plates, preventing material from spilling out through the gaps between the screen plates. A baffle plate is vertically installed on the screen plate, engaging with overlapping portion one of the screen plate via a mounting groove. The gap between the mounting groove of the baffle plate and overlapping portion one of the screen plate is less than 1mm, further preventing material from escaping through this gap. Compared to existing technologies, the advantages of this invention are: it prevents material from falling from the sides of the screen plates and between adjacent screen plates, ensuring normal material conveying.

[0007] As a further improvement of this utility model, both the first overlapping part and the second overlapping part are upwardly protruding. The length of the first overlapping part is greater than the length of the second overlapping part. The second overlapping part of the screen plate is located below the first overlapping part of the adjacent screen plate, and the edge of the first overlapping part of the screen plate is located above the adjacent screen plate. The first overlapping part protrudes upward, forming a space below it to accommodate the second overlapping part of the adjacent screen plate, preventing material from falling through the gap between the two adjacent screen plates.

[0008] As a further improvement of this utility model, the length of the baffle plate is greater than the length of the screen plate, the head of the baffle plate is located on the front side of the lower screen plate, and the tail of the baffle plate is located on the rear side of the lower screen plate. The extended design of the baffle plate ensures that the material is blocked from both sides of the screen plate.

[0009] As a further improvement of this utility model, the tail of the baffle plate on the screen plate is provided with an avoidance groove corresponding to the overlapping part of the adjacent screen plate.

[0010] As a further improvement of this utility model, the tail end of the baffle plate is integrally provided with a mounting plate, and an outwardly inclined connecting part is provided between the mounting plate and the baffle plate. The mounting plate is parallel to the baffle plate, and the mounting plate of the baffle plate on the screen plate is located above the overlapping part of the adjacent screen plate. An avoidance groove is provided on the mounting plate, and the mounting plate of the baffle plate is in close contact with the adjacent baffle plate. Two adjacent baffle plates are connected by the mounting plate.

[0011] As a further improvement of this utility model, a horizontally extending fixing plate is provided at the bottom of the baffle plate. The length of the fixing plate is less than the length of the baffle plate, and the fixing plate is fixed to the screen plate by fasteners. The baffle plate is installed onto the screen plate by means of the fixing plate.

[0012] As a further improvement of this utility model, a connecting frame is provided on the inner side of each of the two sets of sprocket and chain assemblies corresponding to each screen plate. The connecting frame is fixed to the corresponding screen plate. A bracket beam is provided below each screen plate. Several support plates are provided at intervals along the length of the bracket beam.

Detailed Implementation

[0019] like Figure 1-5 As shown, a dryer screen bed unit assembly includes two sets of parallel sprocket and chain assemblies 1. Between the two sets of sprocket and chain assemblies 1, several screen plates 2 are arranged sequentially along the length direction. The front side of the screen plate 2 is provided with an overlapping part 201, and the rear side of the screen plate 2 is provided with an overlapping part 202. The overlapping part 201 of each screen plate 2 overlaps with the adjacent screen plate 2 and correspondingly blocks the overlapping part 202 of the adjacent screen plate 2. Each screen plate 2 has a baffle plate 3 vertically arranged on its left and right sides. The baffle plate 3 has an installation groove 4 corresponding to the overlapping part 201. The overlapping part 201 fits into the installation groove 4 of the upper baffle plate 3. Both overlapping portion one 201 and overlapping portion two 202 are upwardly protruding. The length of overlapping portion one 201 is greater than the length of overlapping portion two 202. The overlapping portion two 202 of the screen plate 2 is located below the overlapping portion one 201 of the adjacent screen plate 2, and the edge of the overlapping portion one 201 of the screen plate 2 is located above the adjacent screen plate 2. The upward protrusion of overlapping portion one 201 forms a space below it to accommodate the overlapping portion two 202 of the adjacent screen plate 2, preventing material from falling through the gap between the two adjacent screen plates 2.

[0020] The length of the baffle plate 3 is greater than the length of the screen plate 2. The head of the baffle plate 3 is located on the front side of the lower screen plate 2, and the tail of the baffle plate 3 is located on the rear side of the lower screen plate 2. The extended design of the baffle plate 3 ensures that the material is blocked from both sides of the screen plate 2.
