Description
Technical Field
The utility model relates to an excavator technical field's screening fill with area screening function.
Background
The excavator drives an excavator bucket to excavate soil or sand through a bucket cylinder by a connecting rod rocker arm; in the polluted soil remediation project, soil needs to be screened, cleaned and neutralized by a medicament, and the common operation mode is that an excavator excavates and conveys the polluted soil to a drum screening machine for screening; conveying the screened polluted soil into a feed port of a spiral mixer, and spraying leacheate by a high-pressure liquid spraying device on the feed port; fully mixing the polluted soil and the leacheate in the spiral mixer and washing the polluted soil; the washed soil is lifted to a belt filter press for filter pressing to obtain the treated clean soil, and the cost of the soil remediation project is increased due to the multiple working procedures of digging, screening and spraying and leaching.
Disclosure of Invention
The utility model aims at providing a multi-functional screening fill that is used for having on the excavator and excavates, sieves and material interpolation, this screening fill simple structure, convenient operation can improve screening efficiency among the soil repair engineering effectively, reduces soil restoration cost.
In order to achieve the purpose, the invention adopts the technical scheme that:
the utility model provides a screening is fought, and screening is fought and is installed on the actuating arm of excavator, its characterized in that: the screening hopper is of a bucket structure, the front end of the screening hopper is a bucket, the bottom of the screening hopper is composed of a plurality of parallel crushing shaft rollers, the crushing shaft rollers are provided with crushing column teeth, a hydraulic motor drives the crushing shaft rollers to rotate, the crushing shaft rollers crush and screen materials entering the screening hopper, and the crushed materials are discharged from the bottom of the screening hopper; the technical scheme is further explained as follows: an automatic auxiliary filling pipe is arranged on the screening hopper, the auxiliary filling pipe is connected with an auxiliary material box, and auxiliary materials are filled into the materials in the screening hopper through the auxiliary material pipe; the technical scheme is further explained as follows: the crushing roller shafts are driven to rotate by hydraulic motors, 2 adjacent groups of crushing roller shafts rotate in different directions, and 2 hydraulic motors respectively drive the crushing roller shafts in different directions to rotate; the technical scheme is further explained as follows: the gap between the crushing shaft rollers is adjustable.
Compared with the prior art, the utility model has the characteristics of reasonable structure, convenient use, efficiency improvement, etc.
Drawings
Figure 1 is a diagram of a sieve hopper.
Fig. 2 is a view showing the internal structure of the sieving hopper.
Figure 3 is a side view of the sieve hopper.
In the figure: the device comprises a bucket body 1, a connecting mechanism 2, a crushing shaft roller 3, a bucket 4 and a filling auxiliary material pipe 5.
Detailed Description
The invention is further explained with reference to the drawings and the application examples as follows: as shown in the attached drawing, the structure diagram of the screening bucket comprises a bucket main body 1, a connecting mechanism 2, a crushing roller 3, a bucket 4 and a filling auxiliary material pipe 5, wherein the screening bucket consists of two parts, namely a bucket main body and a crushing screening mechanism, in the industries of environmental soil restoration engineering, mine exploitation, building excavation and the like, the screening bucket can replace a common bucket to be installed on an excavator and is used for crushing and screening excavated materials, the bucket main body is installed on a driving arm of the excavator through the connecting mechanism, the bucket is driven by a bucket oil cylinder through a connecting rod rocker arm to excavate soil and sand stones, the bottom of the screening bucket consists of a plurality of parallel crushing rollers, crushing column teeth are arranged on the crushing rollers, the crushing rollers are driven by a hydraulic motor to rotate, the crushing rollers crush and screen the materials entering the screening bucket, the crushed materials are discharged from the bottom of the screening bucket, and in the polluted soil restoration engineering, the excavator provided with the screening hopper has dual functions of excavation and screening, when auxiliary materials for removing heavy metals or other chemical components need to be added, the screening hopper is provided with an automatic auxiliary material filling pipe, the auxiliary material filling pipe is connected with an auxiliary material box, and the auxiliary materials are filled into materials in the screening hopper through the auxiliary material pipe.
The utility model discloses a hydraulic motor drive crushing beam barrel rotates, and the bottom of screening fill is constituteed to a plurality of parallel crushing beam barrels, according to the size of screening material, adjusts the clearance of crushing beam barrel, and adjacent 2 group crushing beam barrels rotate with not equidirectional, and 2 individual hydraulic motor drives not equidirectional crushing beam barrel respectively and rotates, and crushing beam barrel smashes the screening to the material that gets into the screening fill, and the crushing material is got rid of by screening fill bottom.
The above-described embodiments are given solely for the purpose of illustrating the invention more clearly and not for the purpose of limiting the scope of the invention, as various equivalent modifications of the invention will become apparent to those skilled in the art after reading the present specification, within the scope of the appended claims.
