[0003] The utility model aims at providing a snow melting machine discharge valve which realizes the related action by rolling friction.

[0004] The above purpose is achieved in the following way.

[0005] A snow melting machine discharge valve, comprising a stirring barrel and a valve, the valve is arranged on the side wall of the stirring barrel, the valve comprises a seat body, a blocking piece and a handle, the handle and the blocking piece are rotatably arranged on the seat body, the bottom of the handle is provided with a hook-shaped crank, the blocking piece comprises a hooking part and a blocking part, the hooking part is hung on the hook-shaped crank, the stirring barrel is provided with a discharge port, the blocking part blocks the discharge port, the hook-shaped crank is provided with a roller at the end, the roller is connected with the surface of the hooking part in abutment, when the handle rotates, the blocking piece is driven to rotate in the opposite direction, at this time, the roller rolls along the surface of the hooking part to drive the hooking part to rotate to realize the rotation of the blocking part and open the discharge port.

[0006] The purpose of the utility model can also be optimized by the following technical measures.

[0007] Preferably, the blocking piece is provided with a reset spring, when the handle is not subjected to external force, the reset spring resets the blocking piece and drives the handle to reset.

[0008] Preferably, the hook-shaped crank and the handle are an integral structure.

[0009] Preferably, the hook-shaped crank is connected with the handle through bolts.

[0010] After the above technical scheme is adopted, the utility model sets the roller between the hook-shaped crank and the hooking part, so that when the handle rotates, the rolling friction between the hook-shaped crank and the hooking part is changed from sliding friction, and irritating sound is not produced.

[0016] The utility model will be further described below in combination with the drawings and specific embodiments.

[0017] In combination Figures 1 to 3 A snow melting machine discharge valve, comprising a stirring barrel 1 and a valve 2, the valve 2 is arranged on the lateral wall of the stirring barrel 1, the valve 2 comprises a seat body 3, a blocking piece 22 and a handle 21, the handle 21 and the blocking piece 22 are rotatably arranged in the seat body 3 respectively, and an outer shell shielding the inside of the seat body 3 is attached to the outside of the seat body 3.

[0018] The bottom of the handle 21 is provided with a hook-shaped crank 211, the blocking piece 22 comprises a hooking part 221 and a blocking part 222, the hooking part 221 is hung on the hook-shaped crank 211, the stirring barrel 1 is provided with a discharge port 11, the blocking part 222 blocks the discharge port 11, the hook-shaped crank 211 is provided with a roller 212 at the end, the rolling direction of the roller 212 is consistent with the extension direction of the end of the hook-shaped crank 211, and the roller 212 is connected in abutment with the surface of the hooking part 221.

[0019] In combination Figure 4 And Figure 5 When the handle 21 is rotated, the hook-shaped crank 211 is rotated, and at the same time, the roller 212 rolls along the surface of the hooking part 221 to drive the hooking part 221 to rotate in the opposite direction, so that the blocking part 222 rotates together and opens the discharge port 11.

[0020] In combination Figure 2 The blocking piece 22 is provided with a reset spring 223, when the handle 21 is not subjected to external force, the reset spring 223 resets the blocking piece 22, when the handle 21 is not subjected to external force, the reset spring 223 drives the blocking piece 22 to rotate, the blocking part 222 reblocks the discharge port 11, and the hooking part 221 presses the hook-shaped crank 211, and at the same time, the roller 212 rolls along the surface of the hooking part 221 to drive the hook-shaped crank 211 to rotate away from the stirring barrel 1 and reset the handle 21.

[0021] The hook-shaped crank 211 and the handle 21 are an integral structure, and in some technical solutions, the hook-shaped crank 211 is connected with the handle 21 through bolts.
