Description

A kind of seed stem preparation and cutting equipment for cassava planting

technical field

The invention relates to the technical field of cassava planting, in particular to equipment for preparing and cutting seed stems for cassava planting.

Background technique

Cassava, also known as kudzu, is one of the three major potato crops and is known as the "king of starch". Now cassava is grown in many areas and is often used as industrial raw materials such as feed, starch, and fuel ethanol.

The cassava planting process requires the selection of cassava seeds. Healthy, strong, and mature cassava stems should be selected as the seed stems. After selection, the original furrows in the field should be deepened, the cassava stems should be buried, and covered with grass or wool felt. Well, antifreeze, or take the car home, put it in the shade, and it will be easy to plant in the spring of the next year.

There are generally three methods of planting cassava: straight insertion, oblique insertion, and horizontal placement. Each method has its advantages. The straight ones are deeper, drought-resistant and wind-resistant, but the potatoes grow downward and are difficult to pull out and dig. The germination rate of oblique insertion is high, and tubers are concentrated at one end. The tubers grow obliquely and are easy to harvest, but they have poor wind resistance. Potatoes can be formed at both ends of the flat stem, which is more resistant to wind and drought, but it is difficult to emerge. All localities should be flexible in light of specific conditions.

Among them, the cassava seed stem preparation and cutting equipment are generally carried out in steps (you need to throw away the land first, then put in the cut and segmented cassava seed stems, and finally backfill the soil), there are many operating steps, and the machine needs to be adjusted frequently to ensure Each step can cooperate with each other to successfully complete the cassava seed stem preparation and cutting, but there are problems of cumbersome operation and low work efficiency.

The two rotating rods 12 run through and extend out of the working box 1. One end is installed vertically with the tillage wheel 2. The traveling teeth of the tillage wheel 2 are in the shape of a square column, which reduces the contact area with the ground. , so as to have a better grip, the other ends of the two rotating rods 12 are equipped with a first meshing gear 13, and the side wall and the lower bottom of the first meshing gear 13 are respectively meshed with a second meshing gear 14 and a third meshing gear 15, At this time, the second meshing gear 14 and the third meshing gear 15 have no meshing transmission relationship, and the second meshing gear 14 and the third meshing gear 15 are all rotatably connected with the two third meshing gears 15 in the working box 1 inner chamber.

The soil is sufficient, and the second transmission rod 43 is fixedly connected between the two second rotating wheels 41 and the corresponding third meshing gear 15, and the two second rotating wheels 41 rotate in reverse synchronously. Mutual dislocation distribution between return rods 42 is to reduce the occupied volume and optimize the specifications of the whole equipment. The lower bottom of the storage barrel 5 is installed with the lower barrel 51, and the lower barrel 51 is fixedly installed in the inner cavity of the working box 1. The inner diameter of the cylinder 51 is smaller than the inner diameter of the material storage cylinder 5. The purpose is to concentrate the cassava near the cutting blade 17, which is more convenient for the rotary cutting of the cutting blade 17, and the bottom end extends to the bottom of the working box 1. The inner cavity runs through the wall of the outer cylinder and is provided with a slot 52. A baffle 53 is slidably installed in the slot 52. The end of the baffle 53 penetrates the slot 52 and extends into the inner cylinder cavity of the storage barrel 5. The front side of the baffle 53 A handle 54 is fixedly installed to facilitate the withdrawal of the baffle 53, and a socket for the insertion of the baffle 53 is also provided at the wall of the cylinder cavity in the storage barrel 5 corresponding to the slot 52, and the socket matches the slot 52.

Working principle of the present invention:

In the first step, the baffle plate 53 is inserted into the slot 52 by the handle 54 and stretched into the inner cylinder cavity of the material storage barrel 5, and a sufficient amount of cassava is poured into the hopper 55. Due to the blocking of the baffle plate 53, the cassava Will not fall into the lower barrel 51;

In the second step, the equipment is moved to the field that needs to be planted, and the baffle plate 53 is extracted from the inner cylinder cavity of the storage barrel 5 through the handle 54, so that the cassava naturally falls into the lower barrel 51 due to gravity, and At the same time, by holding the two grip bars 18 with both hands, and lifting the two grip bars 18 upwards, the weight of the entire device is fully pressed on the two cultivating wheels 2, which can further ensure that the cultivating wheels 2 are not easy to slip, Push the two handle bars 18 again, and the work box 1 has also been promoted, and now the cultivation wheel 2 can rotate the work box 1 to move forward;

In the third step, when the cultivating wheel 2 rotates, it can drive the corresponding rotating rod 12, and then drive the corresponding first meshing gear 13 to rotate, because the second meshing gear 14 and the third meshing gear 15 mesh with the first meshing gear 13 at the same time installed, so it will drive the second meshing gear 14 and the third meshing gear 15 to rotate at the same time;

In the fourth step, the two second meshing gears 14 respectively drive the corresponding first transmission rod 32 to rotate, and then drive the corresponding first rotating wheel 3 to rotate, which also drives the shovel head 31 to start rotating to plan the soil on the walking path of the equipment , and because the shovel head 31 is in an L-shaped design, when the shovel head 31 rotates with the first rotating wheel 3, the soil that has been planed will be thrown out along the tangential direction of the first rotating wheel 3 due to centrifugal force, and they are respectively located in the walking path. Both sides:

In the fifth step, at the same time, the two third meshing gears 15 will also drive the corresponding cutting blades 17 to rotate through the rotating shaft 16. Since the two cutting blades 17 are parallel but misplaced, the direction of rotation of the two is opposite, and at the same time Cassava can be cut when rotating, and the two cutting blades 17 are designed in a bow-knot shape, so there is a gap between the blades. After the cassava is cut by high-speed rotation, the cassava pieces will fall to the shovel head 31 due to gravity. In the planting ditch, the material is unloaded, and the two third meshing gears 15 will also drive the second rotating wheel 41 to rotate through the second transmission rod 43, and then drive a number of returning soil rods 42 to rotate, and the shovel 31 will be planed away and positioned at the equipment for walking. The soil on both sides of the route is backfilled into the planting ditch and covered on the cassava seed stems to achieve the design purpose of optimizing and reducing operation steps and improving work efficiency.
