[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0018] Example:

[0019] This embodiment discloses a drum separator. Figure 1 to Figure 2 , including a separator body 1 and a cleaning mechanism 2.

[0020] like Figure 1 As shown, the separator body 1 includes a workbench 101, a drum 102 is provided on the workbench 101, and protective covers 103 are provided on both sides of the drum 102; in this embodiment, the separator body 1 is an existing device for sand and gravel separation on the market, and sand and gravel are poured into the drum 102, and the drum 102 is driven to rotate by external power, and fine sand will flow out from the sieve holes of the drum 102, and small stones will remain in the drum 102.

[0021] like Figure 1 , Figure 2 As shown, the cleaning mechanism 2 is arranged on the top of the drum 102.

[0022] Specifically, Figure 1 As shown, the cleaning mechanism 2 includes two symmetrically arranged C-shaped mounting frames 201, a motor 202, a long shaft 203 and a gear belt 206. The two C-shaped mounting frames 201 are respectively covered at both ends of the drum 102, and the two ends of the bottom of the two C-shaped mounting frames 201 are respectively fixedly connected to the two side tables of the two ends of the C-shaped mounting frames 201. The motor 202 is fixedly installed on the top surface of one of the C-shaped mounting frames 201 by screws, and the two ends of the long shaft 203 are rotatably connected to the top inner walls of the two C-shaped mounting frames 201 by mounting bearings. A driven gear 204 is provided at one end of the long shaft 203, and a driving gear 204 is provided at the output end of the motor 202. 5. The driving gear 205 and the driven gear 204 are meshed and transmitted through the gear belt 206. A number of belts 207 are evenly spaced in the middle of the long shaft 203. The motor 202 is driven by the external control mechanism. The driving gear 205, the driven gear 204 and the gear belt 206 drive the long shaft 203 to rotate in the two C-shaped mounting frames 201. The long shaft 203 drives the belt 207 to rotate. Due to the effect of centrifugal force, the belt 207 will straighten and hit the surface of the drum 102 when rotating, and the sand blocked in the sieve hole of the drum 102 will be knocked down, so as to achieve the effect of cleaning the sieve hole of the drum 102 and ensure the passability of the sieve hole of the drum 102.

[0023] Further, such as Figure 1 , Figure 2As shown, a plurality of mounting rings 208 are fixedly sleeved at equal intervals on the surface of the long axis 203, a mounting plate 2081 is provided on one side of the mounting ring 208, a clamping assembly 209 is provided on the mounting plate 2081, one end of the belt 207 is fixedly connected to the surface of one side of the mounting ring 208 through the clamping assembly 209, and the clamping assembly 209 facilitates the disassembly and replacement of the belt 207 after long-term use and damage.

[0024] Furthermore, if Figure 1 , Figure 2 As shown, the clamping assembly 209 includes a bottom plate 2091 and an L-shaped clamping plate 2092. The bottom surface of the bottom plate 2091 is fixedly connected to the surface of the mounting plate 2081. The L-shaped clamping plate 2092 is arranged on the top of the bottom plate 2091. Two baffles 2093 are symmetrically arranged on both sides of one end of the bottom plate 2091. Both sides of one end of the L-shaped clamping plate 2092 are rotatably connected to the opposite sides of the two baffles 2093 through a rotating shaft. One end of the L-shaped clamping plate 2092 is arranged on the opposite side of one end of the bottom plate 2091. A plurality of spikes 2094 are used to move the other end of the L-shaped splint 2092 upward, and one end of the L-shaped splint 2092 rotates on the baffle 2093, and the spikes 2094 are separated from the belt 207. At this time, the damaged belt 207 can be removed, and one end of the new belt 207 is inserted into the clamping space formed by one end of the L-shaped splint 2092 and one end of the bottom plate 2091, and the other end of the L-shaped splint 2092 is pressed downward, and the spikes 2094 are inserted into one end of the belt 207 to fix the new belt 207.

[0025] It is worth noting that if Figure 2 As shown, a spring 2095 is provided between the other end of the base plate 2091 and the other end of the L-shaped clamp 2092, and the two ends of the spring 2095 are respectively fixedly connected to the other end of the base plate 2091 and the opposite surfaces of the other end of the L-shaped clamp 2092. When the other end of the L-shaped clamp 2092 is moved upward, the spring 2095 is stretched. After the new belt is replaced, the spring 2095 is reset to pull the other end of the L-shaped clamp 2092 downward to better fix the belt 207.

[0026] It is worth noting that Figure 1 , Figure 2 As shown, one end of the belt 207 passes through the clamping space formed by one end of the L-shaped clamping plate 2092 and one end of the bottom plate 2091, and the length of the belt 207 is greater than the vertical distance between the long axis 203 and the drum 102, ensuring that the belt 207 can occasionally hit the surface of the drum 102 when rotating.

[0027] Working principle: When the utility model is used, sand and stones are poured into the drum 102, and the drum 102 is driven to rotate by external power. Fine sand will flow out from the sieve holes of the drum 102, and small stones will remain in the drum 102. When wet sand is blocked in the sieve holes of the drum 102, the motor 202 is driven by the external control mechanism, and the long shaft 203 is driven to rotate in the two C-shaped mounting frames 201 through the driving gear 205, the driven gear 204 and the gear belt 206. The long shaft 203 drives the belt 207 to rotate. Due to the effect of centrifugal force, the belt 207 will straighten and hit the surface of the drum 102 when it rotates, and the sand blocked in the drum 102 will be removed. The sand in the sieve holes is knocked down, thereby cleaning the sieve holes of the drum 102 and ensuring the passability of the sieve holes of the drum 102; when the belt 207 needs to be replaced, the other end of the L-shaped clamping plate 2092 is moved upward to pull the spring 2095 to be stretched, one end of the L-shaped clamping plate 2092 rotates on the baffle 2093, and the spike 2094 is separated from the belt 207. At this time, the damaged belt 207 can be removed, and one end of the new belt 207 is inserted into the clamping space formed by one end of the L-shaped clamping plate 2092 and one end of the bottom plate 2091. The spring 2095 drives the L-shaped clamping plate 2092 to reset, and the spike 2094 is inserted into one end of the belt 207 to fix the new belt 207.
