Specific implementation

[0026] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0027] Refer to Figures 1-5 A drum-type stone washing machine, comprising a cleaning bottom cover 1, a cleaning inner cavity 11 is arranged in the cleaning bottom cover 1, a stone washing roller 22 is arranged in the cleaning inner cavity 11, a mounting plate 3 is arranged below the cleaning bottom cover 1, a base 7 is arranged on the mounting plate 3, a servo motor 2 and an injection pipe 10 are arranged on the cleaning bottom cover 1, a transmission shaft 21 is arranged on the servo motor 2, the transmission shaft 21 is fixedly arranged with the stone washing roller 22, a fixed frame 6 and a connecting rod 13 are arranged on the cleaning bottom cover 1, a feeding pipe 23 is arranged on the stone washing roller 22, and an exhaust pipe 14 is arranged on the cleaning bottom cover 1.

[0028] The mounting plate 3 is provided with a guide slide 31, the guide slide 31 is provided with a sliding seat 5, the sliding seat 5 is provided with an air cylinder 51, the air cylinder 51 is provided with an air cylinder rod 52 and a switch 53, the air cylinder rod 52 is provided with a connecting block 54, the fixed frame 6 is provided with a first joint axle 61, and the connecting rod 13 is provided with a second joint axle 71.

[0029] The cleaning inner cavity 11 is provided with a smooth layer 12, the mounting plate 3 is provided with a positioning groove 4, and the positioning groove 4 is provided with an inclined surface 41. Some structures recorded in the patent are common structures of the drum-type stone washing machine, are prior art, and some existing structures are not marked and need not be described.

[0030] The top view of the fixing frame 6 is a U-shaped structure and is arranged at the left end of the cleaning bottom cover 1. The fixing frame 6 is rotatably arranged with the connecting block 54 through the first connecting shaft 61. The switch 53 can control the motor shaft of the servo motor 2 to rotate slowly, so as to realize accurate positioning of the feeding pipe 23 and the discharge pipe 14. At the same time, when the feeding pipe 23 and the discharge pipe 14 are positioned, the discharge pipe 14 arranged at the inner end face of the cleaning inner cavity 11 will just contact the feeding pipe 23, so as to ensure that the sand and stones are completely discharged.

[0031] The upper end of the cleaning bottom cover 1 is open. The right outer wall surface of the cleaning bottom cover 1 is at an angle of sixty degrees with the horizontal plane. In combination with the smooth layer 12, the convenient discharge of sewage and sand and stones in the later stage is further improved.

[0032] The connecting rod 13 and the base 7 are a group, and there are two symmetrically arranged groups in total. The base 7 is rotatably arranged with the connecting rod 13 through the second connecting shaft 71, so as to improve the supporting stability of the cleaning bottom cover 1 when rotating and tilting.

[0033] The guide sliding groove 31 is a rectangular inner groove as a whole and is slidably arranged with the sliding seat 5. When the cylinder rod 52 extends upward, the sliding seat 5 will slide rightward along the guide sliding groove 31, so as to realize position compensation of the rightward translation of the first connecting shaft 61.

[0034] The feeding pipe 23 has a spacing with the cleaning inner cavity 11. When the rotating stone washing drum 22 rotates, the feeding pipe 23 is prevented from colliding with the cleaning inner cavity 11.

[0035] The positioning groove 4 is a rectangular groove as a whole. The inclined surface 41 is arranged at the right end upper corner of the positioning groove 4 and has an inclination of twenty degrees. The preset material receiving trolley is conveniently driven onto the mounting plate 3, and then is positioned at the inclined cleaning bottom cover 1 and the discharge pipe 14, so as to be ready for receiving sand and stones in the later stage.

[0036] The smooth layer 12 is uniformly coated along the inner cavity wall surface of the cleaning inner cavity 11. The smooth layer 12 is a fluorocarbon coating and has a thickness of fifty to sixty microns. The fluorocarbon coating surface is smooth and flat, and has excellent corrosion resistance and wear resistance.

[0037] Working mode: connect the preset external feeding pipe with the feeding pipe 23, open the preset valve on the feeding pipe 23, then input the sand and stone to be cleaned into the stone washing drum 22 through the preset feeding pump on the external feeding pipe, then pull out the preset external feeding pipe and close the preset valve on the feeding pipe 23, then inject a certain amount of cleaning liquid into the cleaning cavity 11 through the injection pipe 10, then close the preset valve on the injection pipe 10, then cover the preset water baffle on the upper end of the cleaning bottom cover 1 and threadedly lock it (prior art, not drawn), then start the servo motor 2, drive the stone washing drum 22 to rotate at a constant speed through the transmission shaft 21, the sewage formed by mixing the sludge on the contaminated sand and stone with the cleaning liquid can be separated from the sand and stone, the cleaning is realized, and the sewage is discharged through the preset through hole on the stone washing drum 22 and accumulated at the bottom of the cleaning bottom cover 1 (prior art);

[0038] After the cleaning is completed, the air cylinder 51 is started, the air cylinder rod 52 moves upwards, the air cylinder 51 and the sliding seat 5 slide to the right along the guide sliding groove 31, the air cylinder rod 52 moving upwards rotates the cleaning bottom cover 1 clockwise by a certain inclination angle, then the air cylinder 51 is stopped, and the preset valve on the discharge pipe 14 is opened, so that the sewage can be discharged.

[0039] Then, under the control of the switch 53, the servo motor 2 drives the stone washing drum 22 to rotate slowly, when the feeding pipe 23 is aligned with the discharge pipe 14, the servo motor 2 is stopped through the switch 53 and the preset valve on the feeding pipe 23 is opened, at this time, combined with the smooth sliding layer 12, the cleaned sand and stone can be discharged through the feeding pipe 23 and the aligned discharge pipe 14, avoiding the trouble of manually picking up the sand and stone, and improving the convenience of taking out the cleaned sand and stone.

[0040] In addition, the preset material receiving trolley is conveniently pushed into the positioning groove 4 through the inclined surface 41, and the material receiving opening cavity of the preset material receiving trolley is aligned with the discharge pipe 14, then the preset casters of the preset material receiving trolley are braked and positioned (the preset material receiving trolley is prior art, not drawn in the figure), so that the above-mentioned electrically-controlled inclined type can discharge the cleaned sand and stone, and all the cleaned sand and stone can be discharged into the preset material receiving trolley, avoiding that part of the sand and stone is discharged and slides on the mounting plate.

[0041] The above is only the preferred specific implementation mode of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
