During going out and returning to grease-box by heating overflow valve 12, the spill losses of lubricating oil is converted to heat so as to realize pair
The heating of lubricating oil.
Oil absorption filter 10 is provided between the oil inlet and grease-box 6 of heat pump 8.
For the ease of monitoring the pressure of lubricating oil, the lubricating system of the present embodiment also includes being arranged at the fuel-displaced of heat pump 8
Second pressure sensor 9 between mouth and heating overflow valve 12.
In order to accurately be controlled the temperature of the lubricating oil in grease-box, the Lubricating oil heating device of the present embodiment is also
The second temperature sensor 11 of temperature including the lubricating oil for measuring grease-box.Lubricating system includes passing with second temperature
The control device that the coupling of sensor 11 is set, the temperature control that control device measures according to second temperature sensor 11 heat overflow valve
12 oil pressure relief.In Practical Project in use, heating power can be improved by heightening the oil pressure relief of heating overflow valve,
And then shorten the heat time.
Specifically, it can be electromagnetic proportion relief valve to heat overflow valve.Control device controls the electricity of electromagnetic proportion relief valve
Press to control oil pressure relief.The present embodiment by second temperature sensor 11 and control device and heating overflow valve by carrying out coupling
The automation of whole lubricating system is improved since conjunction, so that the temperature of the grease-box of lubricating system accurately controls.
Specifically, the heat pump 8 of the present embodiment is driven by heating motor 7.Controller is surveyed according to second temperature sensor 11
Temperature come control heating motor open or close.
Because portable sand making machine general work is in the outdoor environments such as field, therefore more difficult offer 380V commercial power.
In order to adapt to the limitation of above-mentioned working environment to improve the range of applicability of the portable sand making machine of the present embodiment, the present embodiment
Lubricating system also includes hydraulic control system.The present embodiment controls above-mentioned heating motor 7, conveying horse by hydraulic control system
Up to 13 and the action of fan driving motor.
Specifically, as shown in figure 1, the hydraulic control system of the present embodiment includes hydraulic pump 4 and banked direction control valves 5.Banked direction control valves 5 wraps
Include for controlling the first of heat pump 7 the work connection 51, joining 52 and for controlling wind for controlling the second of delivery pump 13 to work
3rd work connection 53 of fan 173.The present embodiment controls the action of three motors by using banked direction control valves 5 respectively, so that being
That unites is simple and compact for structure.
Further, the hydraulic control system of the present embodiment also includes being used for the engine 3 for driving hydraulic pump.Using starting
Machine 3 is used as power source, meets that field etc. lacks the demand of the work-yard of industrial power.And the lubricating system of the present embodiment is adopted
With full hydraulic drive, compact-sized small volume, it is more suitable for applying on mobile unit.
The hydraulic pump 4 of the present embodiment is variable pump.Hydraulic pump 4 delivers to the hydraulic oil pump in hydraulic oil container 1 in banked direction control valves 5
To provide hydraulic oil for banked direction control valves.Hydraulic oil filter 2 is provided between the oil inlet and hydraulic oil container 1 of hydraulic pump 4.
As shown in figure 1, the lubricating system of the present embodiment also includes two liquid-level switches 23 being arranged in grease-box 6.
Control device by the detection of two liquid-level switches 23 come judge lubricating system whether oil leak.
The course of work of the lubricating system of the sand making machine of the present embodiment is described in detail below：
As shown in figure 1, engine 3 and variable pump drive connection for whole lubricating system to provide power.The system uses
Engine driving, the dependence to industrial power is broken away from, simultaneity factor uses full hydraulic drive, than same power power drive system body
Product greatly reduces, and it is more suitably applied to portable sand making machine.
Variable pump by engine 3 drive and from hydraulic oil container 1 suction out fluid and by control device control banked direction control valves 5 move
Make.Banked direction control valves 5 drives heating motor 7, conveying motor 13 and fan motor action respectively.Heat pump 8 is driven by heating motor 7,
Lubricating oil returns to grease-box 6 by heating overflow valve 12 and realizes heating function.In actual use can be by heightening
The oil pressure relief of overflow valve 12 is heated to improve heating power, shortens the heat time.
Delivery pump 14 is driven by conveying motor 13, and lubricating oil enters respectively through double-drum filter 16 and lubricating oil heat abstractor 17
Enter motor shaft S2 and main frame main shaft S1, by axle bottom after oil lubrication motor shaft and main frame main shaft top and the bottom bearing
Flow back and after the filtering of return filter 22 into grease-box 6, realize lubricating function.
Preferably, the lubricating system of the sand making machine of the present embodiment also includes coupling the display set with control device and deposited
Reservoir.Display is used for the parameters such as pressure, flow, temperature and the liquid level of lubricating oil of real-time display lubricating system.Memory with

In addition, the lubricating system of the present embodiment includes display device, operating personnel can be intuitive to see the parameters of lubricating system
And fault type is found in time so as to beneficial to quickly counter-measure is made, improve the Man machine interaction of lubricating system.
And the control device of the lubricating system of the present embodiment can also be less than range of set value in the parameter of lubricating system
When send alarm signal or stopping signal to prevent lubricating system from damaging.For example, when the liquid level of grease-box is less than setting value,
Control device sends liquid level data and to display and prompts low liquid level warning.Now operating personnel are after low liquid level warning is received
Removal system oil leakage fault simultaneously fills lubricating oil to setting value.Now, control device will be sent to display releases low liquid level report
Alert signal.
And the lubricating system of the present embodiment realizes that the lubricating oil before being started shooting to lubricating system is carried out by heating overflow valve
Heating.After heating overflow valve heats to the lubricating oil in grease-box, control device is to the lubricating oil in grease-box
Temperature and the liquid level of lubricating oil calculated in real time, only when simultaneously the temperature and liquid level of lubricating oil meet to set accordingly
During definite value, control device just sends signal to control conveying pump startup to realize lubrication to the second work connection 52.
Delivery pump 14 start after, first pressure sensor 18, main shaft flow sensor 19, motor drive shaft flow sensor 20,
Two liquid-level switches 23 are in real time by the data transfers such as lubricating oil pressure, main shaft flow, motor drive shaft flow, grease-box liquid level to control
Device processed.Control device compared with setting value and computing, and shows the real-time monitor value of the parameters monitored in real time
