DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] The multifunctional wood crushing equipment disclosed in the present invention is mainly used in existing wood crushing equipment. When crushing wood, in order to improve the uniformity of the size of the crushed wood, a secondary crushing mechanism is arranged inside the existing wood crushing equipment to perform secondary crushing on the large-volume wood after initial crushing. However, some wood still cannot meet the crushing standard after the first and second crushing.

[0033] Reference Figure 1-Figure 10 A multifunctional wood crushing device comprises a screening frame 1, wherein a secondary crushing assembly 11 is arranged inside the screening frame 1, and the secondary crushing assembly 11 comprises a surrounding cylinder 1101 and a built-in rotary cylinder 1105, wherein the surrounding cylinder 1101 is fixedly connected to the inner walls on both sides of the screening frame 1, and the two open ends of the built-in rotary cylinder 1105 are fixedly connected to end circular plates 1102, and the outer side wall of the built-in rotary cylinder 1105 facing upward is provided with a material receiving hole, and the opposite side of the two end circular plates 1102 is provided with a built-in groove, and the inner walls on the opposite side of the two built-in grooves are fixedly connected with multiple sections of liquid at equal distances. The output end of each multi-stage hydraulic cylinder 1117 is fixedly connected with a connecting block 1116, and the insides of the two built-in grooves are fixedly connected with telescopic sealing plates 1109. The connecting block 1116 is fixedly connected to the outer wall of the adjacent telescopic sealing plate 1109. The inner wall of the receiving hole in the middle is fixedly connected with an arc guide rail 1111, and the inner sliding connection of the arc guide rail 1111 is connected with a limiting slider 1112. The bottom of the limiting slider 1112 is fixedly connected with a matching pressure plate 1114, and the matching pressure plate 1114 is provided with pressure grooves 1115 at equal distances.

[0034] In a specific application scenario, after the wood is initially crushed, it accumulates for a period of time and falls between the two sieve plates 1104 below. The two sieve plates 1104 are the two sieve plates 1104 with the largest sieve holes. The forward and reverse motor 17 and the forward and reverse motor 2 1108 are started. Initially, the forward and reverse motor 17 drives the built-in rotary drum 1105 to rotate 180° back and forth, thereby dispersing the wood into the corresponding sieve plates 1104 according to their sizes. At the same time, the forward and reverse motor 2 1108 drives the crushing slices 1110 to crush the wood for the second time. During the rotation of the built-in rotary drum 1105, the pressure plate 1114 rotates back and forth in the arc guide rail 1111, thereby cooperating with the crushing slices 1110 to better realize the secondary crushing of the wood. Because the larger wood is always between the two sieve plates 1104 with larger sieve holes, it can be continuously crushed to ensure that the wood passing through the sieve holes meets the crushing standard, thereby improving the use value of the crushing equipment.

[0035] Specifically, after the forward and reverse motor 7 drives the built-in rotor 1105 to rotate 180° forward and reverse for a period of time, the forward and reverse motor 7 drives the built-in rotor 1105 to rotate 360° reciprocatingly. During the rotation of the built-in rotor 1105, when the discharge hole 1106 overlaps with the discharge connection hole 1107, the wood between the two adjacent screen plates 1104 will fall into the corresponding discharge frame 5 through the discharge hole 1106 and the discharge connection hole 1107, thereby realizing the classification and collection of the wood.

[0036] It should be noted that when the forward and reverse motor 7 drives the built-in drum 1105 to rotate 360°, the two telescopic sealing plates 1109 are in contact, thereby achieving the sealing of the material receiving hole, avoiding leakage of substandard wood between the two sieve plates 1104 below, and ensuring that the wood can meet the crushing standards after crushing.

[0037] Reference Figure 1-Figure 7In a preferred embodiment, the screening frame 1 is fixedly connected to a motor frame 8 on one side of the surrounding cylinder 1101, and a forward and reverse motor 7 is fixedly connected to the motor frame 8. The output shaft of the forward and reverse motor 7 is fixedly connected to a rotating shaft 1103 through a coupling, and one end of the rotating shaft 1103 is fixedly connected to one side of one of the end circular plates 1102. The outer wall of the rotating shaft 1103 is annularly distributed with sieve plates 1104, and the sieve holes of each sieve plate 1104 are different in size. The matching pressure plate 1114 is located between the two sieve plates 1104 with the largest sieve holes, and one of the end circular plates 1102 is provided with a motor slot on one side close to the matching pressure plate 1114, and a forward and reverse motor 1108 is fixedly connected inside the motor slot, and the output shaft of the forward and reverse motor 1108 is fixedly connected to a local rotating rod 1113 through a coupling, and the outer wall of the local rotating rod 1113 is fixedly connected with crushing slices 1110 at equal distances, and the crushing slices 1110 are located inside each pressing groove 1115.

[0038] In the present invention, the surrounding cylinder 1101 and the built-in rotary cylinder 1105 are in a fitted state, and the outer wall of the surrounding cylinder 1101 facing downward is provided with discharge holes 1107 at equal distances, and the outer wall of the built-in rotary cylinder 1105 located in the middle and at the bottom is provided with three discharge holes 1106, and the three discharge holes 1106 are all located between each two adjacent sieve plates 1104. The three discharge holes 1106 correspond to the positions of the three discharge holes 1107 during the rotation process, and the auxiliary screening components 16 are fixedly connected at equal distances on both sides of the pressure plate 1114. , and the auxiliary screening assembly 16 includes a side block 1601, which is fixedly connected to the outer wall of the matching pressure plate 1114 located between each adjacent two pressure grooves 1115, one side of the side block 1601 is fixedly connected to an integration ring 1603, one side of the integration ring 1603 is equidistantly connected to dispersion teeth 1604 through hinges, and each dispersion tooth 1604 is fixedly connected to a connecting spring rod 1602 on the side facing the integration ring 1603, and one end of the connecting spring rod 1602 is fixedly connected to one side of the integration ring 1603.

[0039] Specifically, in the process of the limiting slider 1112 on the pressure plate 1114 reciprocating in the arc guide rail 1111, the dispersion teeth 1604 gradually contact and squeeze the adjacent screen plate 1104. During the squeezing process between the dispersion teeth 1604 and the screen plate 1104, the dispersion teeth 1604 expand outward, and the connecting spring rod 1602 is compressed. During the expansion of the dispersion teeth 1604, the wood on the screen plate 1104 is pushed, thereby accelerating the passage of the wood through the screen plate 1104 and improving the wood screening efficiency. The outward extension of the dispersion teeth 1604 also prevents the accumulation of wood from causing blockage and inability to unload the material.

The inner walls of the crushing frame 3 on both sides close to the driving shaft 20 are connected to the same driven shaft 18 through bearings, and a driven gear disc 17 is fixedly connected to the outer wall of the driven shaft 18. The driving gear disc 19 and the driven gear disc 17 are meshed, and the outer walls of the driving shaft 20 and the driven shaft 18 located inside the crushing frame 3 are fixedly connected with crushing teeth 10 at equal distances, and the crushing teeth 10 located on the driving shaft 20 and the driven shaft 18 are staggered.

[0043] Reference Figure 1 , Figure 2 , Figure 8 and Fig. 9In a preferred embodiment, a feed hole is opened on the outer side wall of the crushing frame 3 facing upward, and a feed processing assembly 4 is arranged inside the feed hole, the feed processing assembly 4 comprises a feed frame 401, the feed frame 401 is fixedly connected to the inner side wall of the feed hole, the inner walls on both sides of the feed frame 401 are connected to the same deflection shaft through bearings, the outer side wall of the deflection shaft is sleeved with a rotating sleeve 409, the outer side wall of the rotating sleeve 409 facing downward is fixedly connected to a deflection plate 402, the top inner wall of the feed frame 401 close to the deflection plate 402 is fixedly connected to an integration rod 404, the bottom of the integration rod 404 is fixedly connected to a reset spring rod 414 at an equidistant distance, one end of the reset spring rod 414 is fixedly connected to one side of the deflection plate 402, the top inner wall of the feed frame 401 close to the deflection plate 402 is fixedly connected to A semicircular dust suction column 406 is provided with dust suction holes 405 on the arc surface of the semicircular dust suction column 406, a surrounding frame 408 is fixedly connected to the outer wall of the semicircular dust suction column 406 facing downward, bristles 407 are equidistantly arranged on the inner wall of the surrounding frame 408, and the bottom end of the surrounding frame 408 is located between the semicircular dust suction column 406 and the deflection plate 402, a dust collecting frame 403 is fixedly connected to the top of the feed frame 401, a pump frame 411 is fixedly connected to the top of the dust collecting frame 403, a dust suction pump 412 is fixedly connected to the inner wall of the pump frame 411, a dust suction end of the dust suction pump 412 is fixedly connected to a suction pipe 410, one end of the suction pipe 410 is plugged into the interior of the semicircular dust suction column 406, a dust conveying end of the dust suction pump 412 is fixedly connected to a dust conveying pipe 413, one end of the dust conveying pipe 413 is plugged into the interior of the dust collecting frame 403.

[0044] Specifically, when feeding wood, the wood is pushed to the deflection plate 402. The wood presses the deflection plate 402 under the action of its own gravity, and the return spring rod 414 is compressed, so that the wood passes through the deflection plate 402 smoothly. After passing through the deflection plate 402, the wood falls into the enclosing frame 408. During its descent, the bristles 407 brush off the dust and impurities attached to the outer wall, and the dust suction pump 412 is started. The dust suction pump 412 collects this part of impurities and dust through the dust suction hole 405. At the same time, during the wood crushing process, the dust suction pump 412 collects the tiny dust generated and raised during the wood crushing process to avoid the escape of this part of dust to cause environmental pollution and affect the health of the staff, thereby improving the functionality of the crushing equipment.

[0045] It should be noted that when all the wood has passed through the deflection plate 402 and fallen into the crushing teeth 10 below, the return spring rod 414 in the compressed state drives the deflection plate 402 to reset, thereby blocking the feed port of the feed frame 401, preventing the debris generated during the crushing process from splashing and causing injuries to surrounding personnel, thereby improving the safety performance of the crushing equipment.

[0046] Working principle: When the wood is fed, the wood is pushed to the deflection plate 402. The wood presses the deflection plate 402 under its own gravity, and the reset spring rod 414 is compressed, and the wood passes through the deflection plate 402 smoothly. After passing through the deflection plate 402, the wood falls into the surrounding frame 408. During the descent, the bristles 407 brush off the dust and impurities attached to the outer wall. After the wood falls into the two rows of crushing teeth 10, the drive motor 9 is started, and the drive motor 9 drives the wood to move. The movable crushing teeth 10 crush the wood, and the crushed wood falls onto the two retention plates 15. After a period of time, the electric telescopic rod 13 is adjusted to drive the retention plates 15 to move to both sides, and the wood gradually falls into the built-in rotary drum 1105. When the wood on the retention plates 15 falls to the bottom, the electric telescopic rod 13 drives the retention plates 15 to close, and the multi-stage hydraulic cylinder 1117 is adjusted to drive the telescopic sealing plate 1109 to close, so as to achieve the blocking of the built-in rotary drum 1105, and then the forward and reverse rotation is started. The motor 1105 is driven by the forward and reverse motor 1108 to rotate back and forth 180 degrees, so that the wood is dispersed into the corresponding sieve plate 1104 according to the size. At the same time, the forward and reverse motor 1108 drives the crushing slice 1110 to crush the wood for the second time. During the rotation of the built-in drum 1105, the pressing plate 1114 rotates back and forth in the arc guide rail 1111, so as to cooperate with the crushing slice 1110 to better crush the wood. For secondary crushing, the forward and reverse motor 7 drives the built-in rotor 1105 to rotate 180° forward and reverse for a period of time, and then the forward and reverse motor 7 drives the built-in rotor 1105 to reciprocate 360°. During the rotation of the built-in rotor 1105, when the discharge hole 1106 overlaps with the discharge connection hole 1107, the wood between the two adjacent screen plates 1104 will fall into the corresponding discharge frame 5 through the discharge hole 1106 and the discharge connection hole 1107, completing the collection of the wood and ending the operation.
