Description

A kind of thick cutting mill

Technical field

The present invention relates to field of agricultural machinery, more particularly, to a kind of thick cutting mill.

Background technology

Hay mover is a kind of one of common weeding machine, and it is used for the weeds on large area soil are carried out pruning whole Reason, thick cutting mill is a type of hay mover.Existing thick cutting mill generally has a chassis, is mounted with four wheels on chassis So that hay mover can be separately placed on ground；During cutting, motor drives mowing impeller by mechanical driving device, In high-speed rotation, too high grass on meadow just can be machined away mowing impeller by the cutting part on mowing impeller.But, existing Thick cutting mill has a weak point of following several respects: 1, the build of existing thick cutting mill larger it is adaptable to farmland weeding；But its support body Structure is fixed, and occupation of land space is larger, is unfavorable for depositing.Secondly, the cutting part of this kind of thick cutting mill is in bottom of the frame, such as cuts Superstructure loosening then needs to be keeped in repair after suspension bracket is by thick cutting mill lifting, very inconvenient；2, the cutting portion on existing thick cutting mill Part mostly is cutting tip, and the stock-removing efficiency of cutting tip is higher, and cutting knife-edge is smooth；But its edge of a knife spoilage is higher, is unsuitable for High intensity is cut, and needs periodically polishing to there is certain danger coefficient when changing and safeguarding, therefore for thick cutting mill this kind of for The not high equipment of cutting flatness requirement, its cutting part need to improve.

Content of the invention

In order to solve the above problems, it is an object of the invention to provide a kind of thick cutting mill, this thick cutting mill structure novelty, a side Face can be folded by frame reduces its floor space, consequently facilitating depositing and safeguarding；On the other hand, its cutting part is changed Enter so as to be adapted to high intensity cutting.

In order to realize above-mentioned purpose, present invention employs following technical scheme:

A kind of thick cutting mill, including frame, and is arranged on the transmission component in frame and cutting assembly；

Described frame includes assembly of trying to stop people from fighting each other, and is arranged on the upper frame trying to stop people from fighting each other on assembly, and is connected to and tries to stop people from fighting each other on assembly end Casing assembly；

Described try to stop people from fighting each other on be additionally provided with storage oil cylinder, twisting pedestal and engaging part, the cylinder ends of storage oil cylinder are hinged on upper frame On, twisting pedestal is fixed in the rearward end tried to stop people from fighting each other, and engaging part is hinged on trying to stop people from fighting each other on front side of twisting pedestal, engaging part with It is connected also by extension spring between trying to stop people from fighting each other；

Described casing assembly includes housing, and is fixed on the link on housing, and is fixed on the hinge on link end Close sliding seat；Described housing is in downward opening u shape, and enclosure interior forms cutting chamber, and the side accent in cutting chamber hangs There is a plurality of gear chain；Described twisting sliding seat is hinged on twisting pedestal by the first axostylus axostyle, and twisting sliding seat is provided with axis, receives Receive the output shaft end of oil cylinder and described axis is hinged；When described storage hydraulic oil cylinder driving twisting sliding seat rotates, twisting sliding seat On axis can be with described engaging part phase clamping；

Described transmission component includes the power transmission shaft for connecting power source, and the first belt wheel being connected with transmission shaft driven, with And the second belt wheel being connected with the first belt wheel by belt, and the 3rd belt wheel being connected with the second belt wheel by belt, And the gear-box being connected with the 3rd belt wheel；Bearing plate is fixed with trying to stop people from fighting each other below described upper frame, the two of bearing plate All it is positioned with bearing block, the first belt wheel is positioned on bearing block by the second axostylus axostyle, and power transmission shaft is connected to by tapered sleeve on side On one side end of the second axostylus axostyle；Described second belt wheel is positioned on twisting pedestal by the first axostylus axostyle, and lives with described twisting Dynamic seat is coaxially disposed, and the 3rd belt wheel is positioned on the input shaft of described gear-box；Described gear-box location and installation on housing, tooth The output of roller box is in the cutting intracavity of housing；

Described cutting assembly is connected on the outfan of gear-box, and cutting assembly includes filling chain casing, and is arranged on dress chain box Dress chain case lid on body, and it is positioned at the cutting chain on dress chain casing；The section of described dress chain casing is rounded, fills chain casing Wall box on offer multiple box openings, dress chain case lid is circular cover, and the plate body side of dress chain case lid is provided with many Root locating rod；The inner end of described cutting chain is fixing on the securing lever, and the serobila of cutting chain passes through described box opening；Described cut Cut at least two, chain, two cutting chains are on the same RADIAL of dress chain casing.

The present invention adopts technique scheme, and the thick cutting mill of this row has a following both sides advantage:

1, the trying to stop people from fighting each other of this thick cutting mill is provided with storage oil cylinder, twisting pedestal and engaging part, the twisting sliding seat of link is led to Cross the first axostylus axostyle to be hinged on the twisting pedestal tried to stop people from fighting each other, the output shaft end of storage oil cylinder is hinged with described twisting sliding seat；Should The driving that structure passes through to receive oil cylinder can achieve link and relatively rotating between trying to stop people from fighting each other, thus can be by the cutting of this thick cutting mill Position lifting；When storage hydraulic oil cylinder driving twisting sliding seat rotates, the axis in twisting sliding seat can be with described engaging part phase Clamping, its clamping relation can provide and fixedly positioning, and long-time for the cutting part of thick cutting mill lifting is fixed, and it is fixed on the one hand to can be used for Phase deposits, and reduces thick cutting mill storage area, so that cutting assembly is exposed, is easy to the dimension for cutting part for the user Shield and replacing.

2, this thick cutting mill employs cutting chain and replaces traditional cutting tip, needs transmission component to drive cutting chain high during use Speed rotates thus realizing cutting, and therefore it drives needs bigger power with respect to conventional cutting insert.But adopt cutting chain On the one hand the cutting hardness of thick cutting mill can be greatly promoted it is adaptable to the complexity agro-farming environment such as farmland；On the other hand, cutting chain cutting When it is in casing lower end, even if its high-speed rotation also can ensure its safety；Cutting chain safeguard, change when, or be as Under above-mentioned thick cutting mill receiving state, when cutting chain is exposed to outside, because cutting chain does not have the sharp edge of a knife, thus its safety Property greatly reinforces.
