Description

A multifunctional portable cassava harvester

technical field

The utility model belongs to the technical field of agricultural appliances, in particular to a cassava harvester.

Background technique

The main uses of cassava are food, feed and industrial development and utilization. Root starch is one of the main starch raw materials in industry. 65% of the world's total production of cassava is used for human food, and it is the main food crop for low-income farmers in tropical wetlands. At present, during the harvesting period of cassava, the harvesting methods mainly include mechanized harvesting and manual harvesting. The former mechanized harvesting will inevitably become a trend, but in the face of small farmland with steep slopes, the cost of mechanized operations is expensive, and sometimes it is even impossible to operate, because Most cassava is planted on slopes over 30° or interplanted in forests with irregular row spacing. Therefore, people usually adopt the latter, that is, the mode of artificial harvesting, but the cassava tubers grow around the stem, and for the harvest of cassava, people usually grasp its stem with hands and then pull it up firmly, because the mature stem petiole marks Protrusions, long-term labor will cause greater damage to the hands, and the labor intensity is also high; or use more primitive agricultural tools, such as shovels or hoes, which have low production efficiency and are easy to break or dig uncleanly. At present, the existing farm tool for harvesting cassava roots is a toothed cassava harvester, which is provided with a V-shaped locking tooth at one end of the lever, and uses the principle of leverage to pull up the cassava roots. The harvesting efficiency of primitive agricultural tools is higher, but there are the following disadvantages. First, before pulling out potatoes, people usually cut off the stalks with a knife, leaving only 20cm~40cm stalks on the ground. It is easy to pull out potatoes, but the bayonet cassava harvester does not have this function, which is inconvenient; second, if the soil is hard on the floor, it is difficult to pull out potatoes. At this time, it is necessary to loosen the surface soil to easily pull out potatoes, or when pulling out some cassava If it is broken in the soil, it needs to be dug with a shovel at this time, but the bayonet cassava harvester does not have this function, which is inconvenient; third, the bayonet cassava harvester can only be operated by one person when pulling potatoes, because the bayonet is located in the On one side of the lever, the operator needs to use force from one side of the body, which will increase the labor intensity of the operator after a long time of use, and when encountering cassava roots that are difficult to pull up, it is difficult for one person to pull up, and sometimes the cassava stalks will be broken. Reduce harvesting efficiency; Fourth, for reducing weight, levers are generally wooden materials, which are easy to break during use or after using for a long time.

Contents of the invention

Aiming at the defects in the above-mentioned prior art, the utility model provides a time-saving and labor-saving, high harvesting efficiency, can reduce labor intensity, easy to carry, sturdy and practical multifunctional portable cassava harvester, the multifunctional portable cassava harvester The utility model integrates potato pulling, soil shoveling, stem cutting, portability and firmness, and solves the shortcomings of the prior art. It has the characteristics of reasonable design, simple structure, convenient operation, and various functions, and has high use and promotion value.

The purpose of this utility model is achieved through the following technical solutions.

A multifunctional portable cassava harvester, which includes a folding shovel, a knife body, a connecting rod, a V-shaped bayonet connector, a short connecting rod, and a long connecting rod; the folding shovel and the knife body are connected to the front end of the connecting rod through a movable shaft The two sides of the V-shaped bayonet connector are composed of a fixed rod and a movable rod, and the fixed rod and the movable rod are connected through a movable shaft. The inner sides of the fixed rod and the movable rod are serrated; the V-shaped bayonet connection One end of the fixed rod of the device is connected with the connecting rod, and the other end is connected with the long connecting rod; the movable rod is connected with the short connecting rod.

As a further optimization of the technical solution, a knife body groove is provided on the connecting rod, and the length and depth of the knife body groove match the knife body, so that the knife body can be easily retracted into the groove and avoid hurting people.

As a further preferred technical solution, the folding shovel includes a main body and a folding part, and the main body and the folding part are connected by hinges, so as to realize the folding of both sides of the shovel body.

As a further preference of the technical solution, the fixed rod and the connecting rod, the fixed rod and the long connecting rod, and the movable rod and the short connecting rod are all connected by threads, such as in the form of threaded protrusions and threaded grooves.

As a further preference of the technical solution, the tail end of the short connecting rod is provided with a threaded groove, so that the short connecting rod can also be disassembled and combined with the connecting rod.

The portable multifunctional cassava harvester of the utility model is made of stainless steel and has the characteristics of firmness and durability. When not in use, the folding shovel and knife body can be retracted inward through the movable shaft, and the V-shaped snap-tooth connector can also be tightened.

The beneficial effects of the utility model:

1. The portable multifunctional cassava harvester in the utility model is a combined structure, and each section is connected by a threaded connection. When carrying, the various parts are rotated into an integrated structure, which is convenient for carrying. When in use, it has various functions and wide uses, and can be used for pulling potatoes, shoveling soil, cutting stems, etc.

2. When the utility model pulls out cassava, it only needs to screw the V-shaped snap-tooth connector with the long connecting rod and the short connecting rod. At this time, a large V shape is formed, and two people can pull out the cassava at the same time. It is suitable for pulling up cassava roots that are difficult to pull out; when using it, two people can use equal force to prevent the cassava stem from being broken, and the body does not need to use force from one side, which effectively reduces the labor intensity of the operator and improves harvesting efficiency.

3. If the stalks are broken by the sawtooth when the lever principle is used to pull the potatoes, but some stalks are still exposed on the surface, the threaded joint at the open end of the fixed rod of the V-shaped bayonet connector of the present invention can be used It is screwed with the short connecting rod; when in use, the teeth are stuck at the bottom of the cassava stalk, and then two people each hold one end of the connecting rod and lift it up at the same time to pull up the cassava root, which solves the problem of pulling cassava by hand. The damage caused and the trouble of digging and shoveling the soil with a shovel.

4. When the utility model is in use, only the connecting rod and the short connecting rod can be screwed together and the shovel or knife tool can be used separately according to the situation. If the cassava root is broken in the soil, you only need to mobilize the movable shaft, and after the folding shovel and the connecting rod are in a straight line, the movable shaft is tightened and fixed, that is, it can be used as a shovel tool, which can be used for digging and shoveling soil. When needing to cut and harvest the seed stem, only need to mobilize the movable shaft, after the knife body and the connecting rod are in a straight line, the movable shaft is tightened and fixed, that is, it is used as a knife tool, and can be used for cutting and harvesting the seed stem. For ease of carrying or when not using the tool, only need to mobilize the movable shaft, draw the two together to be 0 degrees with the connecting rod, then tighten the movable shaft to fix.

5. The utility model is made of stainless steel and has the characteristics of firmness and durability.
