DETAILED DESCRIPTION
[0023] The following will be combined with the embodiments to clearly and completely describe the technical solution 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 of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0024] Embodiment 1:
[0025] See also Figure 1-2 , this embodiment provides a technical solution:
[0026] A woodworking discharger includes a shell 6, and flange plates 3 are provided at the upper and lower ends of the shell 6 for connecting with other equipment. A wood block crushing component and a wood chip conveying component are provided inside the shell 6. The wood block crushing component is located at the feed inlet and is composed of a pair of mutually meshing primary rollers 1. The cross section of the primary roller 1 is like a star with an angle. The two stars mesh with each other for wood block grabbing and wood block cutting. The two primary rollers 1 are fixed to the shell 6 by a first bearing 41 and a second bearing 52; the two primary rollers 1 are interlocked and driven by two gears outside the shell 6, and the primary roller 1 close to the motor 12 is equipped with a pulley 5 next to the gear, and the belt 9 is connected to the motor 12 as a driving source. The wood chip conveying component is a secondary roller 8, which is located at the discharger outlet and is used for air locking, dust removal and wood chip conveying; the cross section of the secondary roller 8 is similar to that of the primary roller 1, and is also a star with corners. Different from the sharp corners of the primary roller 1, the tip of the corner of the secondary roller 8 is flat and not sharp; the secondary roller 8 is fixed inside the housing 6 through the third bearing 81, and the secondary roller pulley 7 is installed outside the housing 6. The secondary roller pulley 7 is connected to the motor 12 to drive the secondary roller 8 to rotate. The two meshing primary rollers 1 and secondary rollers are parallel to each other.
[0027] There is a cavity between the primary roller 1 and the secondary roller 8 for caching the cut wood blocks.
[0028] A primary guide plate 2 and a secondary guide plate 13 are also provided inside the shell 6 . The primary guide plate 2 is used to guide the wood blocks into the primary roller 1 , and the secondary guide plate 13 is used to guide the wood chips buffered in the cavity into the secondary roller 8 .
[0029] A motor 12 is installed on one side of the housing 6. The motor 12 is fixed to the discharger housing 6 through a motor bracket 11. A motor pulley 10 is installed at the output end of the motor 12. The motor pulley 10 is connected to the pulleys 5 of the primary roller 1 and the secondary roller 8 through a belt 9 for driving.
[0030] Working process:
[0031] The motor 12 is powered on, and the motor 12 drives the primary roller 1 and the secondary roller 8 to rotate. The waste wood blocks enter from the feed port of the discharger, and are guided into the primary roller 1 through the guide plate. The two primary rollers 1 rotate towards each other, cutting the incoming wood blocks into wood chips. The wood chips pass through the secondary guide plate 13 and enter the secondary roller 8. The rotating secondary roller 8 transports the wood chips to the discharger outlet, completing the discharge. When the primary roller 1 processes a lot of wood chips, the wood chips can be temporarily stored in the cavity between the primary roller 1 and the secondary roller 8.
[0032] Embodiment 2:
[0033] Different from the continuous unloading of the first embodiment, this embodiment is aimed at the weight requirements of wood chips when packaging in the market, and is improved on the basis of the first embodiment. The continuous unloading is changed to intermittent unloading, and intermittent unloading can be performed according to the weight requirements, thereby eliminating the weight packaging process.
[0034] like Figure 3 A synchronous member 82 and a weight sensor are installed on the third bearing 81 of the secondary roller 8. The synchronous member 82 is connected to the weight sensor through an electrical signal. The synchronous member 82 is movable in the cavity between the housing 6 and the baffle 14. When the weight sensor detects that the weight of the loaded wood chips meets the standard, an electrical signal is sent to control the synchronous member 82 to abut against the secondary roller pulley 7, thereby driving the secondary roller 8 to rotate; after rotating one-third of a circle, the synchronous member 82 is disconnected from the secondary roller pulley 7, and the secondary roller 8 stops rotating, and intermittent unloading is performed in this cycle.
[0035] like Figure 4-5 In order to further accurately meet the weight requirements, a telescopic shell 84 is sleeved on the top of the secondary roller blade 83 in the axial direction. The telescopic shell 84 fits with the inner wall of the shell 6 of the secondary roller 8 part, so that the wood chips falling between the blades 83 will not fall out from the gap between the blades 83 and the inner wall of the shell 6. The telescopic shell 84 is connected to the secondary roller blade 83 through a spring 85. When the secondary roller blade 83 rotates from the discharge port or the cavity between the primary roller 1 and the secondary roller 8 to the inner wall of the shell 6, the spring 85 in the telescopic shell 84 at the top of the secondary roller blade 83 is compressed, so that the telescopic shell 84 fits with the inner wall of the shell 6; when the secondary roller blade 83 rotates into the discharge port or the cavity between the primary roller 1 and the secondary roller 8, the spring 85 is restored. The side of the telescopic shell 84 close to the inner wall of the shell 6 is an inclined surface, which facilitates the telescopic shell 84 to fit with the inner wall of the shell 6.
[0036] In this embodiment, the synchronous part adopts a 220 single-slot six-hole clutch, and a suitable clutch or other types of synchronous parts can also be selected according to the actual size of the discharger; the weight sensor adopts a TR3D-B-1K weighing sensor.
[0037] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
