Abstract
The utility model relates to a circular arc shape reciprocating type tea-picking blade and belongs to the technical field of agricultural machinery. The blade comprises a lower blade with a radian and an upper blade matched with the lower blade. A tooth shape edge forming a sheared opening is respectively arranged on one side of the upper blade and one side of the lower blade. The middle portions of one sides, deviating from shaving teeth, of the upper blade and the lower blade respectively extends out of a drive connecting handle. A transmission connecting hole is formed in the middle of the drive connecting handle. According to the circular arc shape reciprocating type tea-picking blade, an original blade structure is improved, and the transmission connecting hole is moved from one end to the middle portion. Therefore, the blade is simplified to be a cantilever beam protruding out toward two ends, span is decreased by half than the original span, and maximum amplitude is also decreased by half. Vibration energy losses of the blade can be obviously reduced, shearing is more powerful, abrasion of the blade is even, and service life is obviously prolonged.
Description
Technical field
The utility model relates to a kind of utensil of picking tea-leaves, and the reciprocating type blade of picking tea-leaves of especially a kind of circular arc belongs to agricultural machinery technological field.
Background technology
Understand according to the applicant, the blade of picking tea-leaves has a variety of, and wherein the circular arc blade meets naturally the pick tea-leaves shape of face of tea tree, is conducive to the operation of picking tea-leaves, and uses comparatively general.Tea picking machine in the past is backpack or hand is lifted formula, limit by its structure, drives the end that connecting portion is installed in blade.During work, cutter moves back and forth under the drive unit effect, forms shear action with bottom knife.Owing to have certain interval between two blades, moving back and forth the vibration amplitude that produces is increased by drive end to the other end gradually along cutter, and the distance between the two blade mating surfaces can increase gradually.So, far away apart from drive end, shear just more difficult.Simultaneously, the frictional force of two blade mating surfaces is inhomogeneous, and the result causes blade abrasion also inhomogeneous, and is large near the partial frictional power of drive end, quick abrasion; And little away from the partial frictional power of drive end, wearing and tearing are slow.This wearing and tearing are inhomogeneous so that blade can not continue use through adjusting.
Summary of the invention
The purpose of this utility model is: for the problem that above-mentioned prior art exists, propose that a kind of shear effect is good, the reciprocating type blade of picking tea-leaves of the circular arc of blade long service life.
In order to reach above purpose, the reciprocating type blade of picking tea-leaves of circular arc of the present utility model comprises the bottom knife with radian and the cutter that matches with it, and a side of described upper and lower blade has respectively the dentation blade that consists of sheared edge; The middle side part that described upper and lower blade deviates from shaving extends respectively the driving connection handle, and the middle part of described driving connection handle has the hole of being in transmission connection.
The utility model improves original blade structure, in the middle of the Kong Congyi that will be in transmission connection end moves on to.Therefore, blade is reduced to the cantilever beam that stretches out to two ends, and span had reduced half than originally, and peak swing has also reduced half thereupon.Like this, the vibrational energy loss of blade is significantly reduced, shear become stronger, and the wearing and tearing of blade be comparatively even, obviously prolong service life.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is upper (or lower) blade structure schematic diagram of an embodiment of the utility model.
Fig. 2 is the upward view of Fig. 1.
Embodiment
Embodiment one
The basic structure of the reciprocating type blade of picking tea-leaves of the circular arc of present embodiment is made of the bottom knife with radian and the cutter that matches with it as depicted in figs. 1 and 2, and a side of upper and lower blade 1 has respectively the dentation blade 2 that consists of sheared edge; The middle side part that upper and lower blade 1 deviates from shaving extends respectively driving connection handle 3, and the middle part of this driving connection handle has the hole that is in transmission connection of rectangle.The middle part of upper and lower blade 1 has long slot bore spaced apart along its length 4, and its length is decided according to the size of the amplitude of shearing.During use, be connected with the eccentric wheel driving mechanism by the hole 3 that is in transmission connection, long slot bore 4 play the guiding role.
When driving the eccentric wheel rotation, blade moves back and forth motion, mutually shears, and realizes the required function of picking tea-leaves.In the middle of Kong Congyi end will move on to owing to will be in transmission connection, so blade is improved to the cantilever beam that stretches out to two ends by original unidirectional cantilever, and span has reduced half, and peak swing is also corresponding to have reduced half.So not only reduce the energy loss that vibration causes, so that shear become easy, the wearing and tearing of blade have been become evenly, obviously prolonged the life-span.
Claims (3)
1. the reciprocating type blade of picking tea-leaves of circular arc comprises the bottom knife with radian and the cutter that matches with it, and a side of described upper and lower blade has respectively the dentation blade that consists of sheared edge; It is characterized in that: the middle side part that described upper and lower blade deviates from shaving extends respectively the driving connection handle, and the middle part of described driving connection handle has the hole of being in transmission connection.
2. the reciprocating type blade of picking tea-leaves of circular arc according to claim 1, it is characterized in that: the described hole that is in transmission connection is rectangle.
