Description

Multifunctional thresher

The utility model relates to a kind of farm machinery, and particularly a kind of thresher of cylinder band spike-tooth is mainly used in the threshing of carrying out paddy and wheat.

Common thresher drum has the end cap of two tape spool covers, and wherein an end cap is near belt pulley, and two end cap is connected by the tooth plate of several band spike-tooths, and axle sleeve is fixed in the rotating shaft with screw with axle.Known this thresher function singleness; often only be used for particle is stripped down from cane; but the user wishes that described threshing function has other functions concurrently; to deal with other needs that use occasion occurs; for example cutting up with a hay cutter grass cuts the dish; farmings such as mill starch are quiet, it is reported that in fact this demand exists.

The purpose of this utility model promptly is to provide a kind of such device, and described device is as the optional equipment of known thresher, combines not only with thresher and can finish threshing, and can finish the hand hay cutter grass and cut the dish, grind starch, make known thresher have multi-functional effect.

For achieving the above object, scheme of the present utility model is: the end cap disk 2 that keeps clear of belt pulley one end locate be provided with pointed tooth on the end face, and demountable cutting knife is installed, described pointed tooth top or cutting knife cutting edge all separately and relative bucket wall be separated with the gap.

Other features of the present utility model also comprise, pointed tooth or cutting knife all separately and the gap that has of relative bucket wall be 2-5mm at least.

Scheme of the present utility model is to consider like this, and when only cutting knife being installed on the end cap disk, the hand hay cutter grass can be used to cut the dish; When folding falls cutting knife, when only pointed tooth being arranged on the end cap disk, can be used to grind starch, described attachment device does not hinder the threshing function simultaneously, therefore, only former type is made little change, has promptly realized the purpose of multi-functional machine.

Below in conjunction with drawings and Examples scheme of the present utility model is further described.

Fig. 1 is the installation diagram of thresher;

Fig. 2 is the partial view that is carved with spike-tooth and the installation diagram of cutting knife is housed;

Fig. 3 is the sectional view of cutting knife;

Fig. 4 is the front view of end cap disk;

Fig. 5 is the front view that the end cap disk of pointed tooth dish is installed;

Fig. 1 is a kind of known thresher; be with two end cap disk 2 and 6 on the rotating shaft 1; two ends shrouding disc 2 and 6 and axle 1 affixed use trip bolt 4; trip bolt 4 is embedded in the axial trough 5; for adapting to needs of the present utility model; described axial trough 5 has certain length allowance in the axial direction, after unclamping screw 4, makes cylinder move certain distance at axial direction.

Fig. 2 is the partial view that relates to the utility model scheme, be not carved with pointed tooth 7 on belt pulley end cap disk 2 on one side on the cylinder, and the tooth depth of pointed tooth is generally 1-5mm; When needs are cut the dish the hand hay cutter grass, cutting knife 8 is installed, described cutting knife 8 is installed along the radial direction of end cap disk 2, and the length of cutting knife extends to the limit of end cap disk 2 always from the center of end cap disk, and described cutting knife and end cap disk connect with screw.The mounting means of cutting knife also has other schemes, for example becomes certain included angle to install with radial direction, but effect best be mounting means by present embodiment.

Cooperate above improvement; this device also is provided with feed hopper 9; described feed hopper is a bucket-shaped container; one hopper plate 11 that tilts is arranged; near end cap disk 2 a upright bucket wall 12 is arranged; have charging aperture 10; described bucket wall 12 all is separated with the gap respectively with pointed tooth or cutting knife; the bucket wall 12 and the pointed tooth top of present embodiment are separated with the 2-5 mm clearance; when cutting knife is installed; the gap of the blade of cutting knife and bucket wall 12 also is the 2-5 millimeter, and described bucket wall 12 also is an end face part of thresher hood 13 simultaneously.

In order to form the cutting angle, cutting knife cross sectional shape such as Fig. 3 of present embodiment, described cutting knife have an installation base surface 8, are connected with the cutter hub 12 of a bending, and the point 13 on the cross sectional shape promptly forms cutting edge in the longitudinal direction.On the installation base surface 14 screw hole is arranged, so that install with end cap disk 2.

Fig. 4 is the front view that cutting knife is installed and is carved with the end cap disk 2 of spike-tooth; The pointed tooth of present embodiment is that irregular cutter is on end cap disk, saidly irregularly show that the arrangement of pointed tooth is not equidistant, certainly, by equidistant orderly arrangement also is that this programme is considered, but should consider to leave enough benchmark when arranging for cutting knife is installed, the cutting knife of present embodiment is a radial distribution, and described cutting knife is distributed to rare 2 like this.Not necessarily directly cut a hole on end cap disk 2 as the pointed tooth that abrasive dust is used, also can pre-processed pointed tooth dish, be directly installed on during use on the end cap disk 2, as shown in Figure 5 Jia Gong pointed tooth dish and be installed in situation on the end cap disk.The pointed tooth dish is made three, and every is connected with end cap disk with screw, and certainly, the pointed tooth dish that connects more than 2 or 3 at iron chains on the end cap disk also allows.

The using method of present embodiment is as follows: when needs are used the thresher abrasive dust, unclamp the trip bolt 4 of cylinder, the gap that pointed tooth on the adjustment end cap disk 2 and bucket wall are 12 is 2mm, tightens the trip bolt 4 of cylinder then, can begin abrasive dust; As the hand hay cutter grass of will cutting the dish, on end cap disk 2, cutting knife is installed, the gap of adjusting cutting knife blade and bucket wall 12 is 2mm, can cut the dish.

Thresher of the present utility model owing to increased above-mentioned functions, has been realized one-machine-multi-function, meets China's reality, Gu that this practicality is a property is very significant.
