Embodiment 1：

Disclosed in the present embodiment is a kind of chipper, is a kind of garden instrument, is mainly used in carrying out branch, weeds etc. Crush, including casing 1, casing 1 includes crushing chamber 102 and the tapping channel 103 connected with crushing chamber 102, wherein inside casing 1 Feedboard 11 is installed, the upper area of feedboard 11 forms feed cavity 101, charging hole, branch, weeds are provided with feedboard 11 Entered Deng by charging hole in crushing chamber 102, be additionally provided with motor 2 in the casing 1, be provided with the crushing chamber 102 with The pulverized blade 3 such as Disintegrating knife 3, branch, weeds that motor 2 connects is entered in tapping channel 103 after crushing, final row Go out.

And the improvement of the present embodiment is, a pusher 4 is provided with the tapping channel 103, the pusher 4 can be with Pulverized thing is released into discharging out of tapping channel 103, thus largely avoids pulverized thing from being deposited in tapping channel The problem of in 103, reduce resistance of the pulverized thing to Disintegrating knife 3.

Specifically, pusher 4 is to include rotating shaft 41 and helical blade 42, when rotating shaft 41 rotates, can drive spiral Blade 42 is rotated, and helical blade 42 is not specifically addressed, in helical blade from being a kind of known technology in mechanical field 42 when rotating, and can produce spiral thrust to pulverized thing, so as to allow pulverized thing can smooth release, the thrust of spiral is relative to biography The linear thrust of system, first by the way of being to rotate, driving source can use the forms such as motor, and structure is relatively simple, secondly The thrust of spiral is more smoothly, is unlikely to that moment is stuck, and fault rate is smaller.

In addition, in the present embodiment, be also provided with convex tendon 43 on helical blade 42, convex tendon 43 can increase pulverized thing with Frictional force between helical blade 42 so that helical blade 42 to pulverized thing when promoting, it is not easy to skids, releases effect Fruit becomes apparent from, and convex tendon 43 can be integrally formed or be independently mounted on helical blade 42 with helical blade 42.This Outside, the quantity of convex tendon 43 can be multiple to be distributed in the surface of helical blade 42, when it is implemented, convex tendon 43 can be The lower convex tendon for being located at the upper convex tendon of the upper surface of helical blade 42 or being located on the lower surface of helical blade 42, or together When include upper convex tendon and lower convex tendon, the present embodiment show the upper surface of helical blade 42 set on convex tendon, lower convex tendon is not Show in fig. 1 and 2.

In being worked in gardens, branch in chipper, weeds etc. are placed into, are all much to carry many water, this When a little moisture are promoted in tapping channel 103 by pusher 4, it can be extruded and stay on helical blade 42, so that many grass Bits can because be bonded on helical blade 42 the reason for moisture, in order to reduce residual moisture on helical blade 42, while also allow from Final crushed material in tapping channel 103 out can realize that moisture and broken careless, broken leaf separate, in the present embodiment, the rotating shaft 41 are provided with hollow cavity 401, and the hollow cavity 401 in the present embodiment penetrates the bottom of rotating shaft 41, all sides of the rotating shaft 41 It is communicated with hole 402 between hollow cavity 401, the quantity of intercommunicating pore 402 can be set multiple.When broken careless, broken leaf is in spiral When being promoted on blade 42, the water being extruded has part to be flowed into intercommunicating pore 402, in then being entered by intercommunicating pore 402 Empty inner chamber 401, so as to realize the effect of moisture separation to a certain extent.

The chipper of the present embodiment also includes collecting box 5, connects between the collecting box 5 and the hollow cavity 401 Water pipe 51 is connected to, water pipe 51 is preferably flexible pipe, can be with the releasable connection of rotating shaft 41, and after so designing, the water in hollow cavity 401 exists It can be entered under the influence of gravity by water pipe 51 in collecting box 5, when storage has expired rear centralized and unified discharge.

In order to which water can be preferably directed into intercommunicating pore 402, the upper convex tendon by the rotating shaft 41 all sides Starting to radially extend, the intercommunicating pore 402 is located at the upper convex tendon and 41 weeks sides of rotating shaft intersection, after being so designed that, When water is flowed at convex tendon, it can be stopped by upper convex tendon, as shown in Figure 2, due to the outer end 431 of the upper convex tendon of the present embodiment The inner 432 to upper convex tendon between in the height direction in being gradually reduced trend, Gu Shui can be suitable along the edge of upper convex tendon Potential barrier moves, and is directed into the intercommunicating pore 402 at upper convex tendon the inner, completes guiding.

That is, the upper convex tendon in the present embodiment, is to possess two effects in fact, one is for increasing to pulverized The thrust of thing, second, being the flow direction for guiding water, it is set to flow to intercommunicating pore 102.Two are completed with a feature Function, cost is lower, more compact in structure, is also useful in the present embodiment very much.

In addition, the floor projection of the convex tendon 43 is curved, the rotation direction of the protrusion direction of arc and the helical blade 42 Unanimously, the convex tendon 43 that arc is set can allow water fluidly more smooth.

For other structures, the motor 2 includes output shaft, and the Disintegrating knife 3 is socketed on the output shaft, institute State pusher 4 and be located at the lower section of Disintegrating knife 3, and the top of the rotating shaft 41 and the output axis connection, i.e. the present embodiment In, rotating shaft 41, Disintegrating knife 3 are all a public motors 2, lower in cost so without extra driving source, and structure It is upper more compact, provide more spaces for crushing chamber 102.

In addition, the centre of feedboard 11 convexes to form an installation cavity upward, the motor 2 is then contained in installation cavity, Feedboard 11 is fixed with the support of motor 2 below installation cavity, and the motor 2 is arranged on the support of motor 2.

The bottom of the casing 1 is provided with bottom plate 12, and bottom plate 12 is provided with discharge opening and bearing block 121, pulverized broken grass It can be discharged with broken branch from discharge opening, the present embodiment bottom bracket 121 is located at the centre of bottom plate 12, the bottom of the rotating shaft 41 On the bearing block 121, the top and bottom of such rotating shaft 41 are positioned, and the mode of both ends positioning causes rotating shaft 41 Rotation it is more stable.

Embodiment 2

The present embodiment and the difference of embodiment 1 are that convex tendon also includes being located on helical blade lower surface in the present embodiment Lower convex tendon, when the broken careless and broken branch in tapping channel is more, whole pusher can be filled up, convex tendon equally can be right at present for this Broken careless and broken branch produces thrust.

It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to In this, it is familiar with the those skilled in the art and should be understood that the utility model includes but is not limited to accompanying drawing and above specific embodiment party Content described in formula.Any modification without departing from function and structure principle of the present utility model is intended to be included in claims Scope in.
