Description

Pulverizer for tree branches

The utility model belongs to the manufacturing installation of wood fibre.

The utility model is mainly used in the preparation that edible fungus industrial is produced required a kind of culture medium major ingredient-wood chip powder.Over the years, the artificial mushroom culture in China rural area, black fungus and white fungus are used the trunk of diameter more than 60 millimeters and straight branch more, are cut into Duan Mu and cultivate.From early eighties, with the wood dust technology that the bag of major ingredient is planted white fungus and mushroom, progressively promote in the whole nation, included national spark program in 86 years in.The source one of wood dust is the leftover bits and pieces-sawdust of sawmill Furniture Factory at present, the 2nd, utilize the special processing of machinery.Timber disintegrating process of the prior art mainly contains two kinds, and a kind of is to cut into slices earlier afterwards to pulverize, and a kind of is to utilize the combined type circular saw machine once to become the end.November nineteen eighty-three, Fujian Province's agricultural machinery was succeeded in developing ZQ-600 type timber branch slicer and 9FT40 type wood chip pulverizer, referring to " agricultural machanization service newspaper " (now renaming " Chinese agricultural machanization newspaper " as) version on August 13rd, 1984 " the additional introductions of six kinds of cultivating in bag edible mushroom facility " and " agricultural machinery intelligence data " the 8th phase in 1984 " the part process equipment of Edible Fungi ".These two facility are applied in the whole nation.The topping machanism of this slicer is that radiation direction installs 3 blade on a rotating disk.The timber 30 ° of feedings of tilting are cut into thickness and are 4 millimeters sections less than 60 * 20 square millimeters wood chip.Use wood chip pulverizer (hammer slice type) to be ground into the end after the wood chip drying again.Through using, the advantage of this unit is that wooden last quality is good, and its not enough point has three: the match power of (one) section, pulverizing two machines is suitable, and effect differs greatly, and 1 slicer need have more than 10 pulverizer auxiliary work, just can give full play to its work efficiency.Thereby be not easy to complete the selecting for use of rural area small-sized Edible Fungi enterprise; (2) slicer is subjected to intermittently impact load, and vibration and noise are all bigger, add and need manually hold material man-hour, and working condition is relatively poor; (3) slicer requires the cutterhead quality greatly in order to realizing impact cutting with moment of inertia, thereby complete machine must weigh and big the cost height.The combined type circular saw machine, the carpenter garden saw blade multi-disc that is about to use always now is superimposed upon in the rotating shaft pulverizes timber, and its advantage is simple in structure, simple for production, saved the section link, can once become the end, it is not enough, and point is: (one) wooden last yield rate is low, sometimes less than 50%; (2) for the cooling saw blade, often need add water, thereby increase the drying cost of wood chip powder; (3) solid steel block weight is big, and power consumption is high, and vibration and noise are big, and by artificial positive feed, working condition is poor; (4) the saw blade mill is repaiied inconvenience, use cost height.Therefore amorphous products still at present.

According to teaching material " logger " on probation (chief editor of Guangxi forest school of the medium forest school in the whole nation, China Forest publishing house, November nineteen eighty-two the 1st edition, the 116th～122 face) introduce, timber is a kind of anisotropic material, and its vertical, horizontal and tangential engineering properties differs widely.If vertically resistance coefficient of (also claiming rift grain) cutting is 1, then laterally the resistance coefficient of (also claiming band) cutting is 0.15, and the resistance coefficient that blocks (also claiming to cut off) cutting can reach 2.Although the ratio of three's resistance coefficient of introducing on the books and periodicals that have is not quite similar, illustrate that all cross cutting resistance minimum is blocked the cutting resistance maximum.The combined type circular saw machine is bordering on and blocks cutting, and power consumption is the highest, and disc slicer place in garden is bordering on straight-cut vertically and between blocking partially.

Main target of the present utility model has two: (one) adopts a kind of method that is bordering on cross cutting, makes cutting resistance near minimum, to reduce power consumption, energy savings; (2) cutting and pulverizing one-stop operation are finished.

It is of the present utility model that to be ground into last device be that blade is installed in the rotary cutting apparatus on the internal cone type tool rest.Can make horizontally, but will increase pay-off.Tilting also can, but make complicated.Preferably make vertically, branch feeds from the top, tool rest be installed in a terminal pad above.Be connected with vee-pulley below the terminal pad (or with vertical electric arbor on connect dish and is connected direct transmission).Vee-pulley is installed on the column by bearing, and column stretches in the tool rest.Outer cover is containing whole tool rest, and the top has charging aperture, and there is tangential outlet the side.Bin is held in the outer cover top, to strengthen the orthostatic and the stability of timber.Last under tool rest and terminal pad action of centrifugal force through the wood that cutting crashes, discharge from outlet automatically.In order to prevent that branch is unable to eat cutter in the inner cone spatial rotational in when cutting, load onto several support plates on the column of tool rest stretching into, the number of support plate also can use gripper feed mechanism separately with to prepare the branch number that feeding processes identical.

Blade is finishing tool sword (also can be the blade that has trapeze cut).Installing hole on the blade is in order to regulating cutting depth.Blade is installed in a side of chip area, and its cutting edge stretches out inner conical surface.

The taper tool rest has the chip area identical with knife number (or make several independent tool rests connect and compose inner conical with terminal pad).The angle of inner cone is decided on the fibre length at required wood end.For example, to be ground into fiber length be 2.9 millimeters, thickness when being 1 millimeter fragment when straight timber need cut, and the garden cone angle should be 40 °.The diameter at the awl awl end, interior garden requires to decide on productivity ratio.The factor that influences power is a lot, when calculating power demand, should do simple test determination.According to test, cutting thorn ash, when angle of encounter be 20 °, when cutting depth is 1 millimeter, cutting resistance is 9.5 newton on the cutting edge of every millimeters long.

Because be bevelling, cutting depth is less again, and during cutting, cut curved surface veneer is owing to the squeezing action of the cutting knife angle of wedge fragments into fragment.Crash panel is installed, to strengthen fragmentation behind the blade.The wood end also will be mixed stirring with other nutriment when making the culture medium of edible mushroom, thereby further obtains pulverizing.According to test, the technical staff who is engaged in Edible Fungi thinks that its degree of grinding can satisfy the requirement of production.

A specific embodiments of the present utility model: as depicted in figs. 1 and 2.Fig. 1 is the front view that the utility model branch becomes last machine, and Fig. 2 is the vertical view of internal cone type rotary cutting apparatus.Can and hold bin (6), outlet (7), tool rest (8), blade (9), crash panel (10), support plate (11) etc. and form by support (1), column (2), transmission mechanism (3), terminal pad (4), outer cover (5), import.

Cone angle is 40 ° in this programme tool rest, and 4 blade, and 3 support plates can feed 3 in the branch of diameter below 60 millimeters simultaneously.When slice thickness is 1 millimeter, when tool rest rotating speed 720 changes per minute, need 7.5 kilowatts of power approximately, about 1500 kilograms of theoretical hourly efficiency.Carry out engine and main frame and split, monomer weight is light, is convenient to mobile operating, selects for use in order to the rural area.

Advantage of the present utility model is: (one) is bordering on cross cutting, and power consumption is little; (2) cutting, pulverizing are finished simultaneously; (3) bite is little, and load evenly vibrates for a short time, and noise is lower; (4) timber is after bin is held in artificial feeding, can automatic feed, operate lightly, and and the timber of feeding into all can be machined away, can not stay butt.Thereby more existing wood chip powder machining machine and tool is superior, has advance and practicality.
