A pressure-resistant ground ventilation cage for grain storage

Abstract

This utility model relates to a pressure-resistant ground ventilation cage for grain storage, comprising a cage body with an inverted "U"-shaped cross-section. The cage body has several evenly distributed perforated bridge-type ventilation holes. Multiple supports are installed within the cage body to support it, with the outer surfaces of the supports abutting against the inner surfaces of the cage body. One end of the cage body has a protruding rib, and the other end has an upward-turned edge with a pressure groove. When two adjacent cage bodies overlap, the protruding rib on one cage body engages with the pressure groove on the other. The beneficial effect is that by installing multiple supports within the cage body, the cage body's compressive strength is improved, preventing abnormal conditions such as top collapse and waist expansion under the pressure of the grain pile.

Description

Technical Field

[0001] This utility model relates to the field of grain storage equipment, and in particular to a pressure-resistant ground ventilation cage for grain storage ventilation. Background Technology

[0002] The ground ventilation cage is a ventilation device used for long-term grain storage. It is mainly suitable for cooling, dehumidifying, and circulating fumigation operations of grains such as wheat, corn, and soybeans.

[0003] Existing ground ventilation cages mainly consist of an inverted "U"-shaped cage body and reinforcing ribs installed in the bottom opening of the cage body. The reinforcing ribs are used to prevent the cage body from opening from the bottom opening under the pressure of the grain pile. However, the existing cage body lacks internal support, and under the pressure of the grain pile, there is a risk of top collapse and waist expansion and deformation. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned problems existing in the prior art and to provide a pressure-resistant ground ventilation cage for grain warehouse ventilation.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] A pressure-resistant ground ventilation cage for grain storage includes a cage body with an inverted "U" shaped cross-section. The cage body has several evenly distributed punch-bridge type ventilation holes. Multiple supports are installed in the cage body to support the cage body. The outer side of the supports abuts against the inner side of the cage body. One end of the cage body is provided with a protruding rib, and the other end of the cage body is provided with an upturned edge. The upturned edge is provided with a pressing groove. When two adjacent cage bodies overlap, the protruding rib on one cage body is inserted into the pressing groove on the other cage body.

[0007] The bracket includes an inverted "U"-shaped support plate, a lower support rod, and an upper support rod. The lower support rod and the upper support rod are respectively welded into the opening of the support plate, and the upper support rod and the lower support rod are parallel to each other.

[0008] The lower support rod has a screw hole at each end, the support plate has a first circular hole at each end that is coaxial with and connected to the screw hole, the bottom of the cage has multiple pairs of second circular holes, and bolts that pass through the adjacent first and second circular holes are screwed into the screw holes.

[0009] Two reinforcing plates arranged in a figure-eight pattern are welded between the upper support rod and the middle of the support plate.

[0010] The cage has horizontally outwardly extending downward flanges on both sides, and multiple third circular holes are provided on the downward flanges. The bottom end of the downward flange is flush with the bottom end of the support.

[0011] The length of the punch-bridge type ventilation hole is 18-20 mm, and the width of the punch-bridge type ventilation hole is 2 mm.

[0012] Preferably, the surface of the cage is provided with a zinc coating, the thickness of which is at least 10 micrometers.

[0013] The beneficial effects of this utility model are: by installing multiple supports in the cage, the cage is supported by the supports, thereby improving the compressive strength of the cage and preventing abnormal conditions such as top collapse and waist expansion of the cage under the pressure of the grain pile.

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 5 As shown, a pressure-resistant ground ventilation cage for grain storage includes a cage body 1 with an inverted "U" shaped cross-section. The cage body 1 has several evenly distributed punch-bridge type ventilation holes 11. The length of the punch-bridge type ventilation holes 11 is 18-20 mm and the width of the punch-bridge type ventilation holes 11 is 2 mm.

[0023] The surface of the cage 1 is coated with a zinc layer, the thickness of which is at least 10 micrometers, to improve the corrosion resistance of the cage 1.

[0024] Multiple supports 2 are installed in the cage 1 to support the cage 1. The outer side of the support 2 abuts against the inner side of the cage 1. The support 2 includes an inverted "U"-shaped support plate 21, a lower support rod 22, and an upper support rod 23. The lower support rod 22 and the upper support rod 23 are respectively welded into the opening of the support plate 21, and the upper support rod 23 is parallel to the lower support rod 22.

[0025] Multiple supports 2 are installed in the cage 1 to support the cage 1, thereby increasing the compressive strength of the cage 1 and preventing abnormal conditions such as top collapse and waist expansion of the cage 1 under the pressure of the grain pile.

[0026] The support plate 21 has an avoidance hole 212, which is connected to the bridge-type ventilation hole 11 on the cage 1 in the area overlapping with the support plate 21, so as to prevent the support plate 21 from blocking the bridge-type ventilation hole 11.

[0027] A screw hole 221 is opened at each end of the lower support rod 22, and a first round hole 211 coaxial with and connected to the screw hole 221 is opened at each end of the support plate 21. Multiple pairs of second round holes 15 are opened at the bottom of the cage body 1. Bolts 3 that pass through the adjacent first round hole 211 and second round hole 15 are screwed into the screw hole 221. The cage body 1 is connected to the bracket 2 by the bolts 3.

[0028] Two reinforcing plates 24 arranged in a figure-eight pattern are welded between the upper support rod 23 and the middle of the support plate 21 to improve the support strength of the middle of the support plate 21.

[0029] One end of the cage body 1 is provided with a protruding rib 12, and the other end of the cage body 1 is provided with an upturned edge 13. The upturned edge 13 is provided with a pressing groove 14. When two adjacent cage bodies 1 overlap, the protruding rib 12 on one cage body 1 is inserted into the pressing groove 14 on the other cage body 1.

[0030] The cage body 1 has horizontally outward extending flanges 16 on both sides. Multiple third round holes 161 are provided on the flanges 16. Expansion bolts are used to pass through the third round holes 161 to install and fix the flanges 16 on the ground of the grain silo.

[0031] The bottom end of the lower flange 16 is flush with the bottom end of the bracket 2.
