[0023] The utility model provides a screen structure of a hammer mill: comprising a plurality of screen frames 101, a plurality of screen bodies 102 and a plurality of fixing mechanisms, each of which comprises a clamping frame 103, an abutment block 104, two fixing pins 105 and two fixing nuts 106. The above solution solves the problem that two adjacent screens in the existing hammer mill screen are fixed by a plurality of bolts, and the operation is not convenient during assembly and disassembly. It can be understood that the above solution can be used in the structure of the screen of the hammer mill.

[0024] According to this specific embodiment, each of the sieve frames 101 is provided with the sieve body 102, and the fixing mechanism is provided between each adjacent two sieve frames 101. Fixed wing plates 107 are fixedly provided on both sides of each sieve frame 101, and the external snap-in connection of the fixed wing plates 107 of each adjacent two sieve frames 101 is provided with the snap-in frame 103. A fixing socket 108 is provided on each of the fixed wing plates 107, and the fixing sockets 108 provided on the adjacent two fixed wing plates 107 are staggered. The two fixing pins 105 are fixedly connected to the abutment block 104, and the fixing pins 105 are adapted to the fixing sockets 108. The abutment block 104 abuts against one end of the outer wall of the snap-in frame 103. A fixing thread 109 is provided on the end of each fixing pin 105 away from the abutment block 104, and the fixing nut 106 is fixed to the fixing nut 106. The fixing thread 109 is adapted to the fixing thread 109, and the end face of the fixing nut 106 abuts against the outer side wall of the end of the clamping frame 103 away from the abutting block 104. After the clamping frame 103 is installed on the outside of the fixing wing plate 107 of the two adjacent sieve frame bodies 101, the fixing pin 105 passes through the clamping frame 103 and is inserted into the corresponding fixing socket 108, so that the abutting block 104 abuts against the end face of the clamping frame 103. Then, the fixing nut 106 is tightened at the fixing thread 109 of the fixing pin 105, so that the fixing nut 106 abuts against the end face of the clamping frame 103 away from the abutting block 104, thereby completing the fixing of the two adjacent sieve frame bodies 101. With the above structure, when fixing the two adjacent sieve frame bodies 101, it is only necessary to tighten the two fixing nuts 106 to complete the fixing, and the operation is more convenient.

[0025] A pull ring 110 is provided on one side of each abutment block 104 away from the clamping frame 103 , and a flexible sleeve 111 is provided on the outside of the pull ring 110 . The setting of the pull ring 110 and the flexible sleeve 111 makes it more convenient to plug and unplug the fixing pin 105 .

Through the snap-in groove 112, the fixed wing plates 107 of the two adjacent screen frames 101 are snap-into the inside of the snap-in frame 103.

[0027] At the same time, two dark grooves 113 are arranged on the outer side wall of each of the clamping frames 103 away from the abutment block 104, and the fixing nut 106 is installed inside the dark groove 113. The arrangement of the dark groove 113 makes the structure of the entire screen structure more beautiful.

[0028] When using the screen structure of a hammer mill of the present embodiment, after the clamping frame 103 is installed on the outside of the fixed wing plates 107 of the two adjacent screen frame bodies 101, the fixing pin 105 passes through the clamping frame 103 and is inserted into the corresponding fixing socket 108, so that the abutment block 104 abuts against the end face of the clamping frame 103, and then the fixing nut 106 is tightened at the fixing thread 109 of the fixing pin 105, so that the fixing nut 106 abuts against the end face of one end of the clamping frame 103 away from the abutment block 104, thereby completing the fixation of the two adjacent screen frame bodies 101. With the above structure, when fixing the two adjacent screen frame bodies 101, it is only necessary to tighten the two fixing nuts 106 to complete the fixation, which is more convenient to operate. In addition, through the provision of the pull ring 110 and the flexible sleeve 111, it is more convenient to remove and insert the fixing pin 105.
