DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Reference Figure 1-5 A flotation machine that is easy to discharge is shown, comprising a flotation machine body 1, a scraper assembly and a scraper assembly. A plurality of threaded blocks 4 are arranged in the flotation machine body 1, and a plurality of driving mechanisms for moving the threaded blocks 4 are arranged on the flotation machine body 1. Active cavities are provided on the plurality of threaded blocks 4, and active plates 5 are provided in the plurality of active cavities. Lifting blocks 6 are installed at the bottom of the plurality of active plates 5, and avoidance holes adapted to the lifting blocks 6 are provided at the bottom of the plurality of threaded blocks 4. Scrapers 7 are installed at the bottom of the plurality of lifting blocks 6. A plurality of L-shaped extrusion blocks 10 are installed on the top inner wall of the flotation machine body 1, and an extrusion mechanism for raising the lifting blocks 6 is provided on the plurality of threaded blocks 4. The extrusion mechanism is installed in cooperation with the L-shaped extrusion block 10. Limiting grooves are provided on the sides of the plurality of lifting blocks 6, and fixing mechanisms adapted to the limiting grooves are provided on the plurality of threaded blocks 4.

[0024] By means of the above structure, when in use, the threaded block 4 is first moved by the driving mechanism, and the movement of the threaded block 4 will move the movable plate 5, and the movement of the movable plate 5 will move the lifting block 6, and the movement of the lifting block 6 will move the scraper 7, thereby scraping the floating objects on the other side toward the scraper assembly, and then discharging through the scraper assembly. At the same time, when the threaded block 4 moves to a certain position, the movable plate 5 will rise through the L-shaped extrusion block 10 and the extrusion mechanism, and the rising of the movable plate 5 will cause the scraper 7 to rise through the lifting block 6. At the same time, the rising of the lifting block 6 will limit it by the fixing mechanism, thereby preventing the scraper 7 from contacting the water surface and scraping the floating objects to the other side when resetting. When the threaded block 4 moves to a certain position, the fixing mechanism will release the fixation of the lifting block 6, and at this time the lifting block 6 will be reset, thereby resetting the scraper 7, thereby performing a cyclic scraping in the flotation machine body 1 to prevent the floating objects from moving away from the scraping assembly and affecting the discharging.

[0025] like Figure 4 As shown, the extrusion mechanism includes a fixed block 8 installed on the side of the movable plate 5, and the sides of the threaded block 4 are provided with fixing holes. One end of the fixed block 8 passes through the fixing hole and is installed with a triangular block 9. An elastic reset unit is provided on the top of the movable plate 5. The advantage of this arrangement is that the scraper 7 can be easily raised by arranging the fixed block 8 and the triangular block 9.

[0026] Specifically, when the inclined surface of the triangular block 9 contacts the side of the L-shaped extrusion block 10, the threaded block 4 continues to move, causing the triangular block 9 to be squeezed and lifted by the L-shaped extrusion block 10. The lifting of the triangular block 9 causes the fixed block 8 to rise, and the lifting of the fixed block 8 causes the movable plate 5 to rise. The lifting of the movable plate 5 causes the lifting block 6 to rise, and then causes the scraper 7 to rise. The lifting block 6 will be unable to move through the fixing mechanism, thereby preventing the scraper 7 from contacting the water surface during the reverse reset movement.

[0027] like Figure 4 As shown, the elastic reset unit includes a reset spring 11 installed on the top of the movable plate 5, and the other end of the reset spring 11 is installed on the top inner wall of the movable cavity. The advantage of such a configuration is that, through the configuration of the reset spring 11, when the lifting block 6 is not fixed and the triangular block 9 is not subjected to force, the movable plate 5 is reset under the action of the reset spring 11, and the reset of the movable plate 5 will reset the scraper 7 through the lifting block 6, thereby causing the scraper 7 to scrape the inside of the flotation machine body 1 again.

[0028] like Figure 5 As shown, the fixing mechanism includes a limiting cavity opened on the threaded block 4 and connected with the avoidance hole, a limiting block 12 is movably arranged on the limiting cavity, a movable plate 13 is installed on the side of the limiting block 12, a movable hole matched with the movable plate 13 is opened on the side of the threaded block 4, an extrusion rod 14 is installed on the side of the movable plate 13, and an elastic extrusion unit is arranged on the side of the limiting block 12. The advantage of such an arrangement is that the setting of the limiting block 12 makes it easy to fix the lifting block 6, and the setting of the movable plate 13 and the extrusion rod 14 makes it easy to release the fixation of the lifting block 6.

[0029] Specifically, when the lifting block 6 moves upward, the limiting groove will move upward. When the limiting groove and the limiting block 12 are aligned with each other, the limiting block 12 enters the limiting groove under the action of the elastic extrusion unit, thereby fixing the lifting block 6, thereby preventing the scraper 7 from contacting the water surface and scraping the floating objects to the other side when it moves in the reverse reset direction. When the extrusion rod 14 contacts the inner wall of the flotation machine body 1, the lifting block 6 will continue to move with the threaded block 4, while the extrusion rod 14 will not move. At this time, the moving plate 13 will not move. The moving plate 13 will not move, which will cause the limiting block 12 to stop moving, thereby causing the lifting block 6 to contact and be fixed. At this time, the scraper 7 will reset, thereby performing cyclic scraping for easy use.

[0030] like Figure 5 As shown, the elastic extrusion unit includes an extrusion spring 15 installed on the side of the limit block 12, and the other end of the extrusion spring 15 is installed on the side inner wall of the limit cavity. The advantage of this arrangement is that through the arrangement of the extrusion spring 15, when the limit groove and the limit block 12 are aligned, the limit block 12 enters the limit groove under the action of the extrusion spring 15.

[0031] like Figure 3 As shown, the driving mechanism includes an L-shaped plate 19 installed on the side of the flotation machine body 1, and the inner wall of the side of the L-shaped plate 19 is installed with a motor 2. The top inner wall of the flotation machine body 1 is provided with a plurality of grooves, and the opposite inner walls of the plurality of grooves are rotatably installed with reciprocating screws 3, one end of one of the reciprocating screws 3 extends to the outside of the flotation machine body 1 and is installed on the output shaft of the motor 2, and a plurality of threaded blocks 4 are respectively threadedly sleeved on the plurality of reciprocating screws 3, and the opposite inner walls of the plurality of grooves are respectively installed with guide rods 18, and the sides of the plurality of threaded blocks 4 are provided with guide holes, and the plurality of guide rods 18 respectively penetrate the plurality of guide holes, and the plurality of reciprocating screws 3 are installed in cooperation with the transmission unit. The advantage of such an arrangement is that the threaded block 4 can be easily moved by the arrangement of the motor 2, the reciprocating screw 3 and the guide rod 18.

[0032] Specifically, the output of the motor 2 causes the reciprocating screw 3 to rotate, and the rotation of the reciprocating screw 3 causes the threaded block 4 to reciprocate under the action of the guide rod 18 .

[0033] like Figure 2 As shown, the transmission unit includes a sprocket 16 sleeved on one of the reciprocating screw rods 3, and one end of the other multiple reciprocating screw rods 3 extends outside the flotation machine body 1 and is installed with a sprocket 16, and the multiple sprockets 16 are meshed and installed with a chain 17. The advantage of this arrangement is that through the arrangement of the sprocket 16 and the chain 17, it is convenient to make the multiple reciprocating screw rods 3 rotate simultaneously.

[0034] Specifically, when one of the reciprocating screw rods 3 rotates, one of the sprocket wheels 16 rotates, and the rotation of one of the sprocket wheels 16 rotates the other sprocket wheels 16 through the chain 17, and the rotation of the other sprocket wheels 16 rotates the other reciprocating screw rods 3, thereby causing multiple reciprocating screw rods 3 to rotate simultaneously.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
