3. Grain cutting prototype
principle
The grain cutting prototype consists of two parts: a mechanical device and an electrical control system.
3.1 Mechanical devices
The mechanical device mainly consists of three parts: a cutting rod, a rotating arm, and a column, as shown in the figure, which can achieve three coordinates
Exercise. The lifting of the column is achieved through oil cylinder lifting, telescopic arm extension and retraction, and the upper and lower parts of the sample rod are all completed by a reducer.
3.2 Equipment transportation
The pillars, telescopic arms, and cutting rods of the grain cutting prototype can all be removed before transportation. Reassemble at the destination. Attention during transportation
Equipment and human safety.
3.3 Equipment InstallationAlign the flange bolt holes under the column with the anchor bolts during installation, tighten the nuts immediately, and pay attention to the rotation of the rotating arm
Is the transfer space sufficient. After the mechanical installation, connect the suction tube to the micro suction device tube.
3.4 Working principle
1. The rotation of the rotating arm is driven by the rotation reduction motor to rotate the straight face gear, thereby driving the rotation of the rotating arm.
2. The rotating arm moves forward and backward, and the expansion and contraction are completed by the reducer.
3. The cutting rod is completed up and down by relying on a reducer.
4. Cutting process
After selecting the cutting point, start the micro grain suction device, then start the lifting motor of the cutting rod and press the down button. When the sample rod is inserted
After entering the grain, the micro grain suction device creates a certain negative pressure between the suction tube and the cutting rod, at which point the grain enters through the sampling hole and passes through the suction
The grain tube enters the micro grain suction device, completing the cutting operation. The depth of inserting the sample rod into the grain can be determined by the height of the vehicle's bottom plate
Low, adjust the lowest limit switch of the cutting rod and automatically detect any height of the car bottom. After reaching the car bottom, it will automatically complete the cutting rod return
Upgrade the function to prevent the sample rod from falling too far and touching the bottom plate of the vehicle, which may damage the sample rod.
4. Use and Maintenance
1. Manual control operation
(1) Turn on the power.
(2) Start the micro grain suction device
(3) Button operation, lifting and lowering of the cutting rod on the workbench panel, moving the cutting cart forward and backward, and rotating the steering arm to the left
Right wait button operation.
2. Remote control operation
When the operator leaves the operating platform, the remote control can be used to operate the movement of the sample rod, sample car, and the rotation of the steering arm.
3. Maintenance
A, Hydraulic oil should be replaced according to the season.
B, The internal filter screen of the micro grain suction device must be cleaned after every 400 vehicles, and it also has an internal filter network pulse of the grain suction device
Automatic cleaning screen function.
C, Regularly check if the grain suction tube is worn or leaking, and replace it in a timely manner.
D, After the cutting is completed, place the cutting rod in the lowest position, move the trolley close to the column position, and place the rotating arm in the non through position
Above the road.
E, During use, regularly check whether the connection points of the electronic control circuit are loose or loose. Exclude it.
