Abstract

The utility model discloses a shearing tool of a mulberry shoot reaper, which comprises a moving cutter which performs reciprocating linear shearing motion and a fixed cutter. Cutter teeth are uniformly arranged on both the moving cutter and the fixed cutter; cutting edges are formed on two sides of the cutter teeth; the shearing tool is characterized in that the cutter teeth of the moving cutter are shaped like a triangle or a trapezoid, with roots being larger than the tops; and the cutter tooth edges of the fixed cutter are shaped like an arc and depressed towards the tooth body. The shearing tool has the advantages that the trapezoid moving cutter is matched with the arc fixed cutter, mulberry twigs in a shearing zone can be effectively prevented from slipping, the quality of mulberry shoot cuts is improved, and at the same time the requirement on production efficiency is satisfied.

Description

Cutting mulberry shoot machine shearing tool

(1) technical field:

The utility model relates to a kind of cutter, is a kind of shearing tool that is installed on the cutting mulberry shoot machine specifically.

(2) background technology:

At present, about more than 2,000 ten thousand families of peasant household of total kind of the Sang Yangcan of China.Yet the silkworm and mulberry production facility is also relatively backward on the whole, and it is main tool that the results of ramulus mori are still cut with manual mulberry mostly.This manual harvesting approach efficiency is low, labour intensity is big, has restricted the lifting of sericulture labor productivity, far can not adapt to the large-scale development demand of sericulture, is difficult to improve the economic benefit that the mulberry planter plants Sang Yangcan.

For realizing the mechanization requirement of labour intensive operations such as ramulus mori results, low-power cutting mulberry shoot machine is designed and uses, what this cutting mulberry shoot machine generally adopted is saw-blade type cutter (moving knife and stationary knife), in the beta pruning process, ramulus mori is easily from slippage between the cutter tooth of moving knife and stationary knife, cause problems such as beta pruning efficient is low, otch is crude, and machine power consumption is big.

(3) utility model content:

At the weak point of existing saw-blade type cutting mulberry shoot machine shearing tool, the utility model provides a kind of cutting mulberry shoot machine shearing tool that improves cutting efficiency and shearing quality.

Can realize the cutting mulberry shoot machine shearing tool of above-mentioned purpose, comprise moving knife and stationary knife, moving knife and stationary knife are fitted mutually and are done toward the complex line shearing motion, moving knife and stationary knife are made of evenly distributed cutter tooth, the cutter tooth both sides offer blade, unlike the prior art originally be the knife-tooth structure that utility model has at first solved stationary knife, in order to prevent that branch from leaving cut point outwards slide (from cut point just effort more far away more) along blade, the version to tooth body sunken inside is adopted on the cutter tooth sword limit of described stationary knife, and this indent sword limit can effectively solve the sliding problem of branch outward.

The shape on described indent sword limit has various ways, but is common type with the arc.

The tooth top of the stationary knife cutter tooth of said structure is preferably less than tooth root, thereby widens the distance of dehiscing between the adjacent cutter tooth, increases the quantity that branch enters, and enhances productivity.

With the cutting tool shape of the moving knife of the stationary knife adapted of said structure be triangular shape or the trapezoidal shape of tooth root greater than tooth top.

According to stressed principle, the grinding angle of moving knife blade is more little, shears laborsavingly more, and palette knife sharpening top rake is too little to cause the cutting edge chipping of breaking easily, and test shows that the blade grinding angle of choosing 35 °～55 ° is proper, and wherein most preferred blade grinding angle is 45 °.

Advantage of the present utility model:

The cutter structure of the utility model cutting mulberry shoot machine shearing tool is trapezoidal shearing to arc, effectively prevents the mulberry shoot slippage in cutting process, has also improved productivity ratio when guaranteeing production efficiency.

(4) description of drawings:

Fig. 1 is the knife-tooth structure schematic diagram of moving knife in a kind of embodiment of the utility model.

Fig. 2 is the structural representation of stationary knife in a kind of embodiment of the utility model.

Figure number sign: 1, moving knife; 2, stationary knife.

(5) embodiment:

The utility model cutting mulberry shoot machine shearing tool is made of moving knife 1 and stationary knife 2, and the single cutter tooth of moving knife 1 evenly is spaced on the push rod that is installed in the cutting mulberry shoot machine, and stationary knife 2 is installed on the base plate of cutting mulberry shoot machine, and evenly distributed on the stationary knife 2 have a cutter tooth.

The cutter tooth of described moving knife 1 is the little trapezoidal shape of the big tooth top of tooth root, and the blade grinding angle of cutter tooth is 45 °; Two screw rod mounting hole site are set, as shown in Figure 1 on each cutter tooth of moving knife 1.

The cutter tooth of described stationary knife 2 is the swelling-waist shape of tooth root greater than tooth top, and the curved shape in sword limit of cutter tooth both sides is to tooth body sunken inside; According to the width of stationary knife 2, the screw rod mounting hole site of even layout is set, as shown in Figure 2 on the stationary knife 2.

When ramulus mori enters the shearing work district that the cutter tooth of moving knife 1 and stationary knife 2 constitutes, thereby moving knife 1 is cut back and forth with stationary knife 2 under the reciprocal drive of push rod and being cut down motion and realize cutting off of ramulus mori.
