Abstract

The invention provides an automatic plough lifting and falling method for a raw coal bunker according to real-time coal levels, and relates to the technical field of automatic plough lifting and falling method.The automatic plough lifting and falling method comprises the following steps that a coal bunker with the lowest coal level is selected for plough falling according to the real-time coal levels of coal bunkers, and if no other coal bunkers trigger low coal level alarming, a current coal plough can be automatically lifted to the high coal level; meanwhile, the coal plough 1 of the coal bunker with the second low coal level automatically falls down to prevent the coal flow from being fed into the wrong bunker, and the coal bunker without the coal plough at last is subjected to priority judgment; and when the low coal level alarm of other coal bunkers occurs and the low coal level alarm of the original coal bunker is not triggered any more, after a period of time, the new low coal level coal bunker is subjected to plough falling, and then the original coal bunker plough is subjected to plough lifting. According to the method, the labor cost is effectively reduced, and the problem of wrong bin adding caused by misoperation in the back-and-forth plough lifting and falling process in inspection is prevented.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automatic lifting and lowering plow method, in particular, especially to a method for automatically lifting and lowering plow in real-time coal position raw coal bunker. BACKGROUND

[0002] The background technology of automatic lifting and lowering plow method mainly comes from the limitations of traditional plow operation and the development needs of agricultural mechanization and industrial automation. In traditional agriculture, the lifting and lowering of plow usually depends on manual operation, which not only has high labor intensity, but also is difficult to achieve precise operation, affecting the efficiency and quality of agricultural production. With the advancement of agricultural modernization, the automation and intelligentization of agricultural machinery are increasingly required, prompting the emergence of automatic lifting and lowering plow technology. This technology introduces sensors, automatic control systems and power devices (such as electric push rods, electro-hydraulic push rods, etc.), which can automatically adjust the lifting and lowering of the plow according to soil conditions, traction, engine speed or the inclination angle of the working machine, etc., so as to achieve precise operation and improve the efficiency and quality of operation. In the industrial field, especially in bulk material conveying systems, the automatic lifting and lowering plow technology of plow unloader has also been widely used, which realizes fast and accurate unloading operation through automatic control, further improving the automation level of industrial production.

[0005] Further, all plow coal devices are lowered before being lifted to prevent coal flow from being added to the wrong bunker.

[0006] Further, all plow coal devices are interlocked with the belt running mode, when switching to remote automatic, the plow coal device performs one-by-one lifting and lowering plow test.

[0007] Further, the plowing process is switched by the upper computer in remote automatic and remote manual mode.

[0008] Further, the plowing process comprises: Mode 1: If there is no low coal level alarm signal initially, then the lifting and lowering plow will be used to add coal sequentially; Mode 2: If a coal bunker initially shows a low coal level alarm signal and that coal bunker is not No. 5, the coal plow in that coal bunker will lower to add coal. Mode 3: If the initial low coal level alarm is in coal bunker No. 5, and the plows in other coal bunkers do not operate until a low coal level alarm occurs in a certain coal bunker, then Mode 2 will be executed.

[0009] Furthermore, the time period is 30-40 minutes.

[0010] Compared with the prior art, the present invention has the following advantages: The method of this invention effectively reduces labor costs and prevents the problem of adding the wrong compartment due to misoperation during the inspection process of lifting and lowering the plow.
