The raking machine is a large-scale automatic device, has high automation degree, perfect safety measures and high working efficiency, is an ideal transportation device used in bulk warehouses, and is mainly used for the arrangement and transportation of bulk warehouses in the large-scale urea industry and the glass industry. Wherein the harrow plate is the part directly contacted with the materials, and the materials are harrow by the force of the harrow plate driven by the harrow chain, so that the materials are sorted.
However, in long-term operation, the chain of the raking machine is loosened or piled, which may affect the working efficiency of the raking machine, cause the abrasion of the chain, or the abnormal engagement between the chain wheel and the chain, or even cause the damage of the whole machine to cause safety accidents.
Disclosure of Invention
The invention aims to provide an automatic rake chain tensioning device of a gate type rake machine, which solves the problem that a rake chain of the rake machine in the prior art is easy to loosen or pile during working.
The technical scheme includes that the automatic rake chain tensioning device of the gate rake feeder comprises an adjusting screw, shaft sleeves are sleeved at two ends of the adjusting screw, tensioning wheels are sleeved on the two shaft sleeves, a spacing ring is arranged at the contact position of the tensioning wheels and the shaft sleeves and fixedly sleeved on the surface of the shaft sleeves, bosses are arranged on the surfaces of the spacing rings and clamped on the inner surfaces of the tensioning wheels, sliding blocks, anti-skidding damping rubber rings and positioning nuts are sequentially sleeved on the adjusting screw outside the two tensioning wheels, lubricating mechanisms are arranged at two ends of the adjusting screw and comprise oil cups fixed on sections at two ends of the adjusting screw, the oil cups are connected with oil pipes through lubricating channels, and pipe orifices of the oil pipes are located at the connecting positions of the spacing rings and the shaft sleeves.
The present invention is also characterized in that,
the lubrication channel is arranged inside the adjusting screw.
The slide block is sleeved on the adjusting screw rod through a slide block sleeve.
The width of the shaft sleeve is larger than that of the tension wheel.
The oil pipe is a rubber hose.
The automatic rake chain tensioning device of the gate rake has the advantages that the most appropriate tensioning ring can be selected according to the tensioning condition of the rake chain to achieve the most appropriate chain working state, and the rake plate is better driven to work. Meanwhile, the chain is prevented from being severely worn and unsafe accidents are avoided.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
The invention discloses an automatic rake chain tensioning device of a gate rake, which is structurally shown in figure 1 and comprises an adjusting screw 6, wherein shaft sleeves 5 are sleeved at two ends of the adjusting screw 6, tensioning wheels 8 are sleeved on the two shaft sleeves 5, a spacing ring 7 is arranged at the contact part of the tensioning wheels 8 and the shaft sleeves 5, the spacing ring 7 is fixedly sleeved on the surface of the shaft sleeves 5, bosses are arranged on the surface of the spacing ring 7 and clamped on the inner surface of the tensioning wheels 8, a sliding block 9, an anti-skidding damping rubber ring 10 and a positioning nut 2 are sequentially sleeved on the adjusting screw 6 at the outer sides of the two tensioning wheels 8, lubricating mechanisms are arranged at two ends of the adjusting screw 6 and comprise oil cups 1 fixed on sections at two ends of the adjusting screw 6, the oil cups 1 are connected with oil pipes 3 through lubricating channels 4, and pipe orifices of the oil pipes 3 are positioned at the connection parts of.
The lubrication channel 4 is placed inside the adjusting screw 6.
The slide block 9 is sleeved on the adjusting screw rod 6 through a slide block sleeve.
The width of the shaft sleeve 5 is larger than that of the tension wheel 8.
The oil pipe 3 is a rubber hose.
When the automatic drag chain tensioning device of the gate-type drag machine is used, as shown in fig. 2, two ends of an adjusting screw rod 6 are fixed on a frame 13 of a main target arm frame body 14, so that an anti-skid damping rubber ring 10 is in contact with the frame, the adjusting screw rod 6 is prevented from being in direct contact with the frame and causing abrasion and damage in the using process, the adjusting screw rod 6 is fixed on the frame 13 by a positioning nut 2, and then drag chains 11 on two sides of a drag plate 12 are sleeved on a tensioning wheel 8, so that the drag chains 11 are tensioned and fixed, and the condition that the drag chains 11 are loosened or piled in the moving process is prevented.
The slider 9 can carry out axial positioning to take-up pulley 8, prevents that take-up pulley 8 from swaying and sliding at the in-process of motion, and oil pipe 3 that oil cup 1 can be connected through lubricated passageway 4 lubricates for spacer ring 7 and axle sleeve 5, guarantees that the take-up pulley operates smoothly at the operation in-process, reduces mechanical wear, and the capacity of oil cup 1 can be changed according to actual work needs by oneself, and the volume of adding oil also can be by oneself to the accuse.
According to the automatic rake chain tensioning device of the gate-type rake material machine, when the rake chain 11 is loosened after being used for a period of time and cannot work any more, the type of the tensioning wheel 8 needs to be changed, so that the tensioning degree of the rake chain 11 meets the working requirement. The specific operation process is that the nut 2 is disassembled, the sliding block 9 is moved, and then the tensioning wheel 8 is replaced. The operation of change process is very simple, and only change take-up pulley 8 can reach the work requirement moreover, and need not change whole overspeed device tensioner, has not only practiced thrift the change time, has improved work efficiency, has also practiced thrift material and cost greatly.
