Abstract

The utility model relates to a rotary cutting type slag removing machine, which is composed of a main machine and a slag removing rake, wherein, the slag removing rake is divided into a rake rack and a rake shaft. A spacing plate is arranged at the lower part of the rake rack; the rack shaft is divided into three sections, and rake teeth form helical line shapes and are arranged on the rake shaft. The speed of the power output shaft of a main machine is changed through the three stages of universal joints, a speed reducer, a chain or gear driving, and the rake teeth rotate in the direction opposite to the walking direction of the main machine; when the rake shaft rotates, the rake teeth cut salt slag and follow the walking of the main machine to pull forwards, and the salt slag is crushed; The slag removing rake of the slag removing machine has strong cutting force, the resistance is little, and the slag removing efficiency is high. The utility model is suitable for salt deposit of which the thickness is more than 3 cm, and various slag removing work in a crystallisation sump of which the brine depth is more than 30 cm.

Description

Rotary cutting type slag removing machine

The utility model rotary cutting type salt crystal raking machine belongs to the improvement of salt-field machinery.

When utilizing the big area crystallizing pond to evaporate brine, the salt crystallization is together connected to each other, form certain thickness big area crystallizing layer, this crystallizing layer has certain degree of hardness, must pull the drag fragmentation by the salt worker the earliest with its fragmentation to improve salt matter in crystallisation process or before the collection salt, this is the heavy manual work of benzene, use traction formula quarrel rake alive later on again instead, utilize the main frame power quarrel rake of drive living to advance, the quarrel of living rake teeth makes salt deposit be the broken shape of straight way, and this quarrel of living harrows that specific pressure is big over the ground, main frame wheel destructible salt pond plate, influence salt quality, the vertical pulling resistance is big during operation, when running into very the kieserohalosylvite layer, rake teeth can only be on salt deposit cut, when running into soft salt deposit, rake teeth is pricked down, and resistance is just big, therefore the bad control of rake teeth height, crushing effect is bad.

The utility model purpose provides a kind of rotary cutting type salt crystal raking machine that overcomes above-mentioned shortcoming, be installed on the rake axle because rake teeth is linear in the shape of a spiral, when therefore the rake axle rotated, rake teeth had rotary cutting power and the two kinds of reactive forces of pulling force that advance to salt deposit, and the quarrel of living efficient has obviously improved.

With reference to accompanying drawing 1,2, the utility model rotary cutting type salt crystal raking machine is to realize like this, 2. 1. it harrow with the quarrel of living by main frame, and two portions constitute, the quarrel of living rake is reverse rotary cutting type structure in the main frame direction of travel, 4. the 3. linear in the shape of a spiral rake axle that is installed on of rake teeth is gone up, 4. the rake axle is divided into three joints, 5. being fixed in the rake frame with flange 6. goes up, 7. 6. the rake frame be connected with the main frame balance staff, 8. the main frame power output shaft is connected with a universal joint end 9., the universal joint the other end be installed on rake frame crossbearer intermediary step-down gear and 10. be connected speed reducer output shaft

Be connected in the rake axle 4. by chain drive or geartransmission, rake frame 6. below is equipped with limiting plate

, harrow the frame crossbeam in addition on the rake frame

, at crossbeam On two hydraulic suspension pull bars are arranged , it and main frame suspension arm Connect.

With reference to accompanying

drawing

3,4, the rake frame limiting plate of the utility model rotary cutting type salt crystal raking machine is to install like this: the rake frame 6. below spacing grillage of welding perpendicular to the rake frame , on spacing grillage, open four holes, at limiting plate

Go up four screw rods of vertical welding

, screw rod is by spacing grillage

Four holes, at the both sides in hole nut

Locking will be changed the limiting plate upper-lower position, as long as adjusting screw(rod)

Height.

Described speed reducer output shaft

And rake axle chain drive or the geartransmission transmission case that partly is closed in rake frame rear portion between 4.

In.

When the main frame of the utility model rotary cutting type salt crystal raking machine is walked forward, 4. the rake axle is rearward to rotate, also be reverse in the main frame direction of travel, be installed on the rake axle because rake teeth is linear in the shape of a spiral, axially rotate and main frame when walking forward rake teeth down-cutting salt deposit in the back at rake, and pulling forward, existing like this cutting force has motive force again, and different with traction formula quarrel rake alive is that the instantaneous contact tangent plane rake of this device rake teeth gear ratio traction formula rake row formula rake teeth number of teeth that is cut alive will be lacked, so resistance is just little.

The host machine part of the utility model rotary cutting type salt crystal raking machine has also been done many improvement, and is lower as the former machine brake case ground clearance, is not suitable for the pond operation of dark halogen, and this machine increases by two idle wheels in not holding transfer gear box, the ground clearance has been increased; Former machine gauge is less, and fuselage improves its stability of back and is affected, and this machine has strengthened gauge; Former machine is the narrow crawler belt of steel, and the life-span is shorter, and specific pressure is bigger over the ground, and this machine adopts the rubber belt track of broad, has strengthened ground contact length, to reduce specific pressure over the ground, has prolonged crawler belt work-ing life simultaneously.

This device main frame speed of a motor vehicle has 6 grades, selects 1,2,3 three shelves during use, and rake axle rotating speed has two grades of height, when salt is cut when hard, can select 1 grade of speed of a motor vehicle (at a slow speed), the rake axle is selected low-grade rotating speed for use, because the rake axle is divided into three joints, also can pull down both sides rake axle when needing, to reduce resistance.

The utility model rotary cutting type salt crystal raking machine adopts the limiting plate device, make the rake frame adjustable according to salt quarrel thickness and hardness position, adopt universal joint to connect main frame and rake frame, adopt hydraulic suspension pull bar and main frame suspension arm syndeton, after rake frame limiting plate position is selected, during the salt crystal raking machine walking, the rake frame also can change automatic control up and down, like this rake frame upper-lower position has been carried out two fixed controls, activity has reduced advance resistance freely when making salt crystal raking machine work.

This device is owing to rake teeth is that spiral line type is distributed on the rake axle, the rake axle is stressed even during operation, and cutting force is big, adopts dual control rake frame height method, the main frame speed of a motor vehicle and rake axle speed change are adjustable, make this function be applicable to that the salt quarrel of different hardness different thickness is broken, resistance is little during operation, and main frame has adopted rubber belt track, increased the main frame height, widened gauge, specific pressure is little over the ground, good stability.

This device is applicable to more than the salt layer thickness 3cm, the quarrel operation of living in the following various crystallizing ponds of brine depth 30cm, and applied widely, the quarrel of living is renderd a service high, is that Salt Making Enterprises improves crude salt output and quality, the comparatively ideal salt crystal raking machine tool of liberating the productive forces.
