Description

Girdling saw for jujube tree

Technical Field

The utility model relates to an agricultural instrument, more specifically say so and relate to a jujube tree is with girdling saw.

Background

The girdling of the jujube tree, namely the girdling of the bone branches in the growing season, can temporarily interrupt the downward conveying of the photosynthetic products, relatively increase the nutrient accumulation at the upper part, meet the requirements of flowering, fruit setting and early growth and development of young fruits, and obviously improve the fruit setting rate and the quality of the jujube fruits. The current common modes are: the bark is cut by a sharp blade, and the two sides of the bark are usually subjected to circular cutting, but the circular cutting is time-consuming and labor-consuming and is not easy to control; part uses wide type shovel, but the wound that forms also enlarges correspondingly, even the girdling is accomplished, but the wound healing is slow, and the injury to the trunk is big, and then influences the fruit setting.

FIG. 1 is a schematic structural view of a girdling saw for jujube trees of the present invention;

FIG. 2 is a top view of FIG. 1;

FIG. 3 is a right side view of FIG. 1;

fig. 4 is an enlarged view of F in fig. 1.

In the figure: 1. the novel saw blade comprises a handle, 2 parts of a saw blade, 3 parts of a fixing hole, 4 parts of a fastening bolt, 5 parts of a concave part, 6 parts of a V-shaped opening, 7 parts of a flat head tooth, 8 parts of a saw tooth, 801 parts of a positioning tooth and 802 parts of a working tooth.

Detailed Description

The utility model discloses a jujube tree is with girdling saw to further describe with specific embodiment with the accompanying drawings below:

fig. 1 is a schematic structural view of a girdling saw for jujube trees according to the present invention, fig. 2 is a plan view of fig. 1, and fig. 4 is an enlarged view of F in fig. 1. In the drawing, including saw bit and the fixed handle in saw bit end, the saw bit has two, and two saw bits are laminated mutually, still include a plurality of sawtooth on the saw bit, the sawtooth comprises location tooth and work tooth, the height of work tooth is less than the location tooth and sets up in proper order interval each other, and the top of location tooth is the crew cut tooth after the passivation. Two fixing holes are further formed in the saw blade, and fastening bolts are arranged in the fixing holes to fix the two saw blades. FIG. 3 is a right side view of FIG. 1, in which the teeth of both saw blades are inclined outward to form inward-concave V-shaped openings, and the saw blades have a thickness of 1.2mm, a tooth depth of 4mm, and a tooth pitch of 4 mm. The handle is provided with an arc-shaped concave part, and the front end of the concave part is connected with the saw teeth, so that the handle is convenient to grasp.

When the girdling saw for the jujube trees is used, a position to be girdled is selected, the handle 1 of the girdling saw is held by the right hand, the upper and lower positions of the sawteeth are controlled by the left hand, the handle 1 is pushed and pulled leftwards and rightwards, the sawteeth 8 can be sunk into the outer skin of the jujube trees due to the fact that the outer skin of the jujube trees is soft plant fibers, the positioning teeth 801 and the working teeth 802 are sunk into the outer skin of the jujube trees, and when the working teeth 802 at the lower position are in contact with the bast at the lower layer of the outer skin of the jujube trees, the soft plant fiber outer skin is cut quickly. When the positioning teeth 801 at the high position continuously enter the bark and abut against the wood layer, the circular cutting saw is pushed and pulled leftwards and rightwards, smooth and labor-saving, and the circular cutting depth of the circular cutting saw is shown to be reached at the moment, because the wood layer is hard and tough, the flat head teeth 7 on the positioning teeth 801 cannot sink into the wood layer any more, the working teeth 802 cannot cut the wood layer to play a role in positioning the circular cutting depth, the circular cutting is continuously performed forwards according to the next step until circular cutting openings at two ends meet, sawdust is removed, and the circular cutting opening is completed.

The utility model discloses a twolip kerf, the circular cutting can one shot forming, improves work efficiency, and the location sawtooth and the work sawtooth of design special construction ensure that the bark is in time healed after the circular cutting at the degree of depth of control circular cutting in the circular cutting, and sharpening part design is removable formula, and easy to process and simple structure change easily.

The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention has been disclosed with reference to the preferred embodiment, it is not limited to the present invention, and any skilled person in the art can make various changes or modifications equivalent to the above embodiments without departing from the scope of the present invention, but all the modifications, changes and modifications of the above embodiments by the technical spirit of the present invention are within the scope of the present invention.
