Description

Technical Field

[0001] The utility model belongs to the technical field of drying machines, and in particular relates to an air duct used for a grain drying machine. Background Art

[0002] A grain dryer can dry out moisture from grains to extend the storage time and prevent mold. The induced draft angle tube can disperse the hot air in the dryer and improve the drying efficiency of the dryer. The current induced draft angle tube is installed in the dryer through a guide plate. The current prior art uses an angle tube in which one end is fixed to a block and the other end is detachably connected to the block. However, this structure has many processing steps during production and a relatively high production cost. In addition, when a problem occurs with the block, it cannot be quickly adapted and repaired, and the entire induced draft duct may even need to be repaired, resulting in high repair costs. Utility Model Content

[0003] The utility model aims to provide an air duct for a grain dryer to solve the above problems existing in the prior art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A draft duct for a grain dryer comprises an angular tube body, both ends of the angular tube body are detachably provided with clamping blocks, a connecting tube is provided on the surface of the clamping blocks, the thickness of the angular tube body is greater than the thickness of the connecting tube, both end faces of the angular tube body are provided with clamping grooves matching with the connecting tube inwardly along the length direction, the connecting tube is embedded in the clamping groove, and the connecting tube is connected to the angular tube body by fastening bolts.

[0006] The working process and principle of the above structure are as follows:

[0007] During production, the angular tube body, the clamping block, and the connecting pipe integrally connected to the clamping block can be produced separately, which reduces the processing steps of the angular tube body and reduces the cost in the production process. At the same time, the clamping block and the connecting pipe are separately arranged from the angular tube body, which helps to quickly insert the angular tube body into the grain dryer. Thereafter, the connecting pipe is quickly inserted into the clamping groove of the angular tube body and fixed with bolts. The connecting pipe is engaged with the clamping groove of the angular tube body, which increases the friction between the angular tube body and the connecting pipe and the connection firmness. When there is a problem with the clamping block or the connecting pipe, only the clamping block with the connecting pipe can be quickly replaced, which improves the maintenance efficiency, eliminates the need to replace the angular tube body, and reduces the maintenance cost.

[0008] Furthermore, a plurality of first bolt holes are opened in a rectangular array on the side of the angular tube body, and a second bolt hole is opened on the connecting tube at a position corresponding to each first bolt hole. The angular tube body and the connecting tube are connected by any two groups of corresponding first bolt holes and second bolt holes and fastening bolts.

[0009] The arrangement of the first bolt holes and the second bolt holes in a rectangular array makes it easy to quickly select two groups of corresponding first bolt holes and second bolt holes and insert the fastening bolts therein, thereby improving the installation efficiency of the clamping block.

[0010] Furthermore, the cross-sectional shape of the angular tube body may be a triangle, a rhombus, a pentagon or an ellipse.

[0011] Angular tube bodies of different shapes can be selected and installed in the dryer as required.

[0012] Furthermore, a layer of rubber pad is bonded to the end surface of one inner end of the fastening bolt.

[0013] The provision of the rubber pad increases the tightening friction of the tightening bolts.

[0014] Furthermore, a sealing rubber ring is sleeved on the connecting pipe, and the sealing rubber ring is tightly fitted to the side surface of the clamping block.

[0015] The provision of the sealing rubber ring increases the sealing performance between the clamping block and the angular tube body.

[0016] Beneficial effects: The utility model can produce the angular tube body, the clamping block and the connecting tube integrally connected to the clamping block separately during production, thereby reducing the processing steps of the angular tube body and reducing the cost in the production process. At the same time, the clamping block is separately arranged with the connecting tube and the angular tube body, which helps to quickly insert the angular tube body into the grain dryer. Thereafter, the connecting tube is quickly inserted into the clamping groove of the angular tube body and fixed with bolts. The connecting tube is engaged with the clamping groove of the angular tube body, which increases the friction force and connection firmness between the angular tube body and the connecting tube. When there is a problem with the clamping block or the connecting tube, only the clamping block with the connecting tube can be quickly replaced, thereby improving the maintenance efficiency, eliminating the need to replace the angular tube body and reducing the maintenance cost.
