Integral vibration measuring discharge and partial cycle grain drying machine

Abstract

The invention discloses an integral vibration measuring discharge and partial cycle grain drying machine. The grain drying machine is composed of a feeding system, a drying warehouse, an elevator, an air network system, a vibration motor, a vibration spring and a frame; the drying warehouse (2) is composed of a warehouse body (8), a warehouse top (7), a discharge hopper (15), an integral vibration measuring discharge hopper (16) air network system and the frame (17); and a top device of the warehouse top (7) is a charging system formed by a burden distribution packing auger (5) and a burden distribution rotating disk (6). The drying machine has the beneficial effect that the integral vibration measuring discharge is employed for realizing grain nondestructive metering discharge, the sectional area of a grain discharge port is large, which is in favor of integral flowing of grains in the drying machine. The grain drying machine can realize quasi-state drying and partial cycle drying technology, which is in favor of minimizing grain damage and in favor of saving operation cost.

Description

technical field [0001] The invention belongs to the field of material drying technical equipment, in particular to grain drying technical equipment, in particular to a grain drying machine with integral vibration metering and partial circulation. Background technique [0002] In recent years, the development of grain drying technology and equipment has been rapid, and more achievements have been achieved. So far, the grain drying methods used mainly include: continuous type, intermittent type, combined type according to the process flow; according to the heating method: indirect type, direct heating type; according to the type of heat source: coal, oil , electricity, biomass energy, etc. In addition, there are solar energy, microwave, far infrared, etc. No matter what kind of drying method is used, in the grain drying process, a process with a relatively large slow speed drying ratio is adopted, and a large slow speed section is designed in the grain drying equipment.

Problems solved by technology

[0009] Chinese Patent Application Publication No. CN201010192148 "A Conveyor Belt Grain Dryer", a conveyor belt-based grain dryer, used to solve the problems of large grain crop drying equipment, inconvenient movement and high investment costs

The mechanism is novel in design, simple and reasonable in structure, reliable in operation, less in failure, but not easy to control

[0012] Chinese Patent Application Publication No. CN200920098924 "grain dryer grain discharge mechanism", on the lower side of the dryer silo, on the upper part of the two inner grain deflectors that are oppositely arranged, the cross section is triangular. The main grain distribution plate is provided with an angular auxiliary grain distribution plate with a triangular cross-section on the upper side of the grain discharge hopper composed of an outer grain deflector and an inner grain deflector, and the angular main grain distribution plate and the The included angle between one side of the angular auxiliary grain distribution plate and the installation vertical line is 30-45°; this mechanism effectively eliminates the phenomenon of uneven discharge speed of grain in the silo of the dryer and in the grain discharge hopper , to achieve uniform discharge and discharge, but the measurement accuracy is poor and it is not easy to control

But this mechanism is not convenient for online operation and adjustment, and the measurement accuracy is closely related to the use time
