Description

The branch cutter mill

Technical field

The utility model relates to a kind of gardening equipment, relates in particular to a kind of branch cutter mill that is used for.

Background technology

The branch cutter mill is the machine that a kind of horticulture is used, its work purpose is the branch or the leaf that drop or cutting is got off are shredded then and there, solve the difficulty that volume and the excessive branch of length cause carrying and handle, simultaneously, chip after the chopping can also help environmental protection as natural fertilizers.

Portable type branch cutter mill of the prior art, its structure is to be provided with an engine, to have cutting knife and cutterhead, a bootable branch or the leaf of dialling the bits blade feed well to this cutterhead in body haply, and one be located at this body and be adjacent to the chip removal mouth of this cutterhead, described engine connects this cutterhead with transmission components such as belts, make cutterhead to be driven in rotation, the related bits blade synchronization of dialling of being located at the cutterhead below that makes is rotated.Described feed well is located at the top of body, the below of feed well then corresponds to the position of cutterhead, therefore, when branch or leaf are dropped into feed well, be directed dropping down onto on the cutterhead, cutterhead in the rotation can and fall to the cutterhead below with branch or leaf shredder, is swept to the chip removal mouth discharge by the chip of dialling after the bits blade will shred again.

Based on the consideration of safety, general branch cutter mill all must be used for preventing the structure that limbs stretch in chip removal mouth design, is hindered to avoid the cutting knife of limbs in being rotated; Described structure of the prior art is at chip removal mouth many roots bar to be set, in case when user or other people limbs stretch into chip removal mouth, be able to stop it deeply by rib; Yet, be provided with rib also must cause chip removal smoothness, especially rib quantity the more, more can cause the accumulation of chip and can't discharge smoothly, if the quantity of rib reduces, may reduce the protection effect that its anti-limbs stretch into.

The utility model content

Main purpose of the present utility model is to provide a kind of limbs of can avoiding to stretch into chip removal mouth, can make chip discharge the chip removal device of body smoothly again, meets safety requirements and chip removal requirement smoothly simultaneously.

In order to achieve the above object, a kind of branch cutter mill provided by the utility model, in body, be provided with an engine, one has cutting knife and the cutterhead of dialling the bits blade, one bootable branch or leaf are to the feed well of this cutterhead, and one be located at this body and be adjacent to the chip removal mouth of this cutterhead, described engine connects this cutterhead with transmission device, to drive this cutterhead and to dial the rotation of bits blade synchronization, use the branch or the leaf shredder that will enter on this cutterhead, and chip is swept to this chip removal mouth by this group bits blade, wherein

Described chip removal mouth is pivoted with a chip removal fan, and this chip removal fan can be accepted the wind-force that is produced when described group of bits blade rotates and rotate, thereby chip is discharged chip removal mouth.

Branch cutter mill described in the utility model, it is chip removal mouth at the branch cutter mill chip removal fan that can rotate freely that is pivoted, when user or other people stretch into chip removal mouth with limbs, can be subjected to this chip removal fan and stop and can't touch cutterhead in the body, thus the safety of maintenance work; The wind-force driven rotary that produces when described chip removal fan then can be rotated by the cutterhead in the body, when branch or leaf are shredded and are swept to chip removal mouth, chip removal fan in the rotation can be taken chip out of chip removal mouth naturally, uses and takes into account simultaneously and work safety and chip removal safety smoothly.

Embodiment

Following conjunction with figs. explanation is done more detailed description to embodiment of the present utility model, and those skilled in the art can be implemented after being familiar with this specification according to this.

At first with reference to figure 1, the branch cutter mill that the utility model provides is a kind of motor driven type machinery that includes body 1, and major function is conveniently to be transported to the place that need shred branch or leaf then and there; It is provided with engine 2 near rear end above body 1, the body top is provided with charging joint 12 near front end, and above charging joint 12, connecting a feed well 13, body the place ahead is provided with a case 11 with chip area 111, is pivoted with a chip removal fan 5 in this chip area 111; The below of body 1 is supported with support 3, and support 3 both sides are provided with wheel 31, can conveniently cutter mill be transported to the place that needs.

Fig. 2, Fig. 2 A and shown in Figure 3 for another example, the branch cutter mill in the utility model is essentially a platform above its body, and the top rear of body 1 is provided with an engine 2, and the inside that engine 2 extends into body then is provided with a drive pulley 21; Top the place ahead of body is provided with the cutterhead 4 of a circle, and the central shaft of cutterhead 4 extends into internal body and is provided with a negative pulley wheel 44, and this drive pulley 21 is connected with at least one belt 22 with negative pulley wheel 44; Described cutterhead 4 is provided with the notch 42 of a plurality of cutting knifes 41 and a plurality of perforation upper and lowers, and is provided with group bits blade 43 below cutterhead 4, makes to dial and considers blade 43 to be worth doing on body 1 and between below the cutterhead 4; The body of corresponding cutterhead 4 tops then is provided with a charging joint 12, and the top of this charging joint 12 connects a feed well 13 again; As shown in Figure 3, the upper end of this feed well 13 can separate out the branch import 131 and leaf import 132 that is positioned at diverse location; The below of body 1 then is arranged at support 3, and support 3 both sides then are provided with wheel 31, support body 1 by support 3.The front end of body 1 is equipped with a case 11 with chip removal mouth 111 again, and a chip removal fan 5 (simultaneously with reference to figure 4) with a plurality of flabellums then is pivoted in the described chip removal mouth 111; The central shaft of chip removal fan 5 is vertical with the central shaft of cutterhead 4, and in other words, chip removal fan 5 can rotate freely on upright direction.

By aforesaid chip removal device, the user can drop into advance the import 131 of branch from feed well 13, and leaf then drops into from leaf import 132, enters branch in the feed well 13 or leaf and promptly is conducted through charging joint 12 and falls within on the cutterhead 4.2 in engine in the running, drive negative pulley wheel 44 and make cutterhead 4 rotations via belt 22 by drive pulley 21, cutterhead 4 in the rotation can utilize the cutting knife 41 above it that branch or leaf are cut into chip, the chip just notch from cutterhead 4 42 falls within above the body under the cutterhead, in this simultaneously, the cutterhead 4 in the rotation promptly utilizes the bits blade 43 of dialling of its below that chip is swept to chip removal mouth 111.The air-flow that is produced when cutterhead 4 rotations then can be led to chip removal mouth and drive 5 rotations of chip removal fan, makes the chip that falls within chip removal fan 5 be able to be rotated chip removal mouth by chip removal fan 5, thereby avoids chip to cause accumulation at chip removal mouth.

The above only is in order to explain preferred embodiment of the present utility model; be not that attempt is done any pro forma restriction to the utility model according to this; be with, all have following of identical spirit do relevant any modification or change, all must be included in the category of the utility model intention protection.
