Urea formaldehyde foam plant cultivation medium grinder

Abstract

The invention relates to a urea formaldehyde foam plant cultivation medium grinder which is characterized by comprising an oblique grinding cylinder, wherein the front end of the oblique grinding cylinder is low, and is provided with a material inlet which is open upward; a material charge hopper is welded at the material inlet; the middle part of the grinding cylinder is provided with a transparent observation window; the tail end of the grinding cylinder is high, and is provided with a material outlet which is open downward; a material discharge sleeve is welded at the material outlet; the material discharge sleeve is internally provided with a drawable screen; a frequency conversion motor speed regulator is connected above the tail end of the grinding cylinder through a platform, and the output end of the frequency conversion motor speed regulator is connected with a small belt wheel; the small belt wheel is connected with a large belt wheel through a belt; the large belt wheel is connected with a main shaft which penetrates through the grinding cylinder and is rotatably connected with the grinding cylinder; packing augers are respectively welded at two ends of the main shaft; a plurality of pairs of stirring teeth are arranged between the two packing augers at intervals; each pair of stirring teeth are radially and symmetrically arranged, and are crossed with adjacent stirring teeth by 90 degrees; the front end of the bottom of the grinding cylinder is provided with a fixing support connected with a pair of front vehicle wheels, and the rear end of the bottom of the grinding cylinder is provided with a height adjusting support connected with a pair of rear vehicle wheels; and the grinding cylinder is provided with a control panel. The urea formaldehyde foam plant cultivation medium grinder provided by the invention can be widely used for grinding urea formaldehyde foam media with different grain diameters.

Description

technical field [0001] The invention relates to a pulverizing device, in particular to a urea-formaldehyde foam plant cultivation substrate pulverizer for agriculture and forestry cultivation. Background technique [0002] Urea-formaldehyde foam is a kind of plant cultivation substrate, which has light texture, good water absorption and water retention, stable structure, low price, simple manufacturing process, and natural decomposition in the soil, saving labor, plant, fertilizer and water in the cultivation process , No pests, no weeds, etc., can be used in plant seedlings, cultivation, improvement of degraded cultivated land, roof greening, water surface greening, green plant landscape modeling in city squares and other fields. The matrix material is made of urea-formaldehyde resin through a foaming molding process, and the initial product is in block shape, which needs to be pulverized and screened to obtain a grain shape suitable for plant growth. The pulverization equ...

AI Technical Summary

Problems solved by technology

The pulverization equipment in the prior art generally completes the pulverization by quickly hitting the object with internal stirring teeth or paddles, while the urea-formaldehyde foam matrix has a low bulk density and low strength. 3mm particle size accounts for 40%, 3mm ~ 5mm particle size particles account for 40%, 5mm ~ 10mm particle size particles account for 20%, it is difficult to use other crushing equipment to achieve the required crushing effect, and the crushing principle and control of other crushing equipment method is also difficult to control the particle size of the urea-formaldehyde foam cultivation substrate
