Description

The automatic powder feeder unit of spraying type stake machine

The utility model relates to a kind of automatic powder feeder unit of spraying type stake machine, belongs to the civil construction Foundation Design and revolves the parts that the formula stake of digging is looked.

The production of existing spraying type stake machine and in the existing experience for many years of the use of soft foundation, but at its one of critical piece, promptly also deposit some shortcomings on the structure of powder feeder unit and the performance, thereby directly have influence on the quality of every pile.At first, because the main frame and the dusting device distance of stake machine are far away, to boring dark and long two indexs of the amount of dusting of unit stake can not be carried out efficient synchronization and monitored, the deviation of the long amount of dusting of the unit's of causing stake, simultaneously, because powder weight dynamic change display unit or discharge record device only are set, can only realize the weight monitoring of single operation, same during to the construction in the whole construction course, the single pile total amount of dusting, the amount of dusting of every meter stake, construction depth and stir data such as the degree of depth again and can not monitor, and need to use manual record, therefore, tend to produce artificial error logging, can not truly intactly react the original data of dusting in the construction, so that influence the quality of pile body.

The purpose of this utility model is: the automatic powder feeder unit that a kind of spraying type stake machine is provided, it has overcome above-mentioned shortcoming, accurately control is equipped with a parameter in the system stake process of spraying type stake machine, comprise engineering time, single pile dust total amount, every meter the stake amount of dusting, construction depth and stir the degree of depth again, and these parameters have unalterable feature, printable when needed come out, thus construction quality guaranteed fully.

The utlity model has following advantage:

But 1, the dynamic parameter of amount of dusting in main frame and the powder feeder unit Synchronization Control system stake process and stake long correlation, and in time regulate.

2, can write down the available machine time, write and remember the pile body sequence number, the stake long and quantity.

3, have left alone without help electric protection function, guarantee that the data of storing do not lose because of left alone without help electricity and left alone without help machine.

4, in the process of system stake, be provided with stage warning and prompting, for operating personnel's reference.

The technical solution of the utility model is: it is made of for powder jar, revolution powder feeder and arrangements for speed regulation, air compressor and major and minor controller, LOAD CELLS, depth transducer and positive and negative retaining controller major and minor.The main powder jar that supplies utilizes 1 to 3 LOAD CELLS to be suspended on the support, and LOAD CELLS and master controller link with cable; Supply to be provided with between the powder jar a secondary powder jar that supplies at air compressor and master, on two conduits that supply between the powder jar, be provided with a powder entering valve; Lead to secondary conduit by air compressor and be provided with each one of one way valve, water-separating gas filter, pressure regulator valve and admission valve for the powder jar; Lead on the conduit of main frame drilling rod through being located at main revolution powder feeder by air compressor for powder jar below, be positioned at the front and back of revolution powder feeder, respectively be provided with dust a valve and an a dishful of valve, on this conduit, also be provided with two brasnch conducts, one leads to main for the powder jar and an admission valve is housed, and it two directly leads to the main frame drilling rod and an admission valve is housed; Master controller (PH-5 type) is provided with a central processing unit A, being contained in the master links for the arrangements for speed regulation cable of the LOAD CELLS on the powder jar by signal amplifier and signal adapter and central processing unit and revolution powder feeder, also be provided with holder, LCD, keyboard and printer, submaster controller (PB-5 type) also is provided with a central processing unit B, the depth transducer that is contained on the main frame drilling rod links with cable by central processing unit B and positive and negative retaining controller, also is provided with keyboard and liquid crystal display; Link with cable is two-way between the major and minor controller.

Consulting accompanying drawing below elaborates to embodiment of the present utility model:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the square frame composition diagram of parts 18 shown in Fig. 1 and 19.

By illustrated in figures 1 and 2, the automatic powder feeder unit of spraying type stake machine is a unit equipment of supplying with cement flour or pulverized limestone for the main frame drilling rod 2 of this machine 1.At first, cement flour or calcium lime powder are poured into the secondary powder jar 3 that supplies, close admission valve 4, enter compressed air by air compressor 5, enter the secondary powder jar 3 that supplies through one way valve 6, branch water filter gas 7 and pressure regulator valve 8, admission valve 9, the powder in it is sent into the main powder jar 11 that supplies through powder entering valve 10, fill it up with up to this jar.Subsequently, the group's of closing powder entering valve 10, outlet valve 12, admission valve 9, admission valve 13 and the valve 14 that dusts are opened admission valve 4 and admission valve 15, the main frame drilling rod 2 of the direct displacement pile machine 1 of compressed air this moment, and main frame drilling rod 2 begins to creep into, till the degree of depth of regulation.Subsequently, 2 counter-rotatings of main frame drilling rod promote, open the valve 14 that dusts, dish valve 16 and admission valve 13 simultaneously, close admission valve 15, and start and to be positioned at main revolution powder feeder 17 for powder jar 11 belows, at this moment, compressed air will turn round the powder that powder feeder 17 supplied with and send into main frame drilling rod 2, be ejected into the soil from the spray orifice of drill bit, mix and pile with soil.Above-mentioned work progress carries out auto-control by master controller 18 and submaster controller 19 (PH-5 type).On the powder jar 11 1 to 3 LOAD CELLS 20 is housed main the confession, they will be led for powder jar 11 by suspension arrangement 21 and hang on the support 22, and when the weight of powder changed, the signal of LOAD CELLS 20 was sent into the central processing unit A of master controller 18 by cable.The signal that is located at the depth transducer 23 on the machine 1 is also sent into the central processing unit A of master controller 18 through submaster controller 19, and when the long amount of dusting of unit stake was below or above set amount, the arrangements for speed regulation 24 of revolution powder feeder 17 were regulated automatically for the powder speed.If from display, find because special soil layer or functional failure of electromechanical when causing the very few or broken pile of certain section pile body amount of dusting; master control can be defeated by main frame with signal to device 18; make main frame drilling rod 2 bore or connect the benefit broken pile again down by keeping off controller 25 anyway; up to stopping below the red dog; main frame drilling rod 2 promotes again; just the unit's of making stake is long reaches setting value for the powder amount for this, finishes multiple spray, stirs and the operation of pile extension again, thereby guaranteed construction quality fully.

The utility model is not only applicable to spraying type stake machine, and is applicable to automatic powder operation, for example making food industry, pharmaceuticals industry, the packaging facilities etc. of supplying in any case.Therefore, all based on principle that the utility model proposed and the modification in the formation scope, all belong to protection domain of the present utility model.
