The development of agricultural mechanization has accelerated the development of modern agriculture and is one of the important contents of modern agriculture. In recent years, my country's agricultural mechanization has prospered and developed. Various agricultural machinery has entered thousands of households. Many farmers have their own agricultural machinery, which has facilitated agricultural production and seized the farming time. In recent years, with the rapid development of industry and commerce, agriculture has suffered a relatively large squeeze. In addition, the low productivity and low economic benefits of traditional agriculture have also caused many farmers to abandon their land and invest in urban construction and industry and commerce, resulting in a great blow to the comprehensive productivity of agriculture. Especially in some mountainous areas, due to the low level of mechanization and heavy physical labor, many people have given up agricultural production, which has also caused a great loss of agricultural productivity in my country. In the face of such a situation, we need to be able to recognize the power of science and technology, and through the popularization of mechanization, to improve the productivity and competitiveness of agriculture, so that the masses can re-recognize the importance and convenience of agricultural production, and enhance their production enthusiasm. In agricultural construction, advanced and applicable agricultural machinery products better meet the needs of agricultural production, liberate more labor, and accelerate the process of agricultural modernization.

In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0025] The utility model is described in detail below with reference to the accompanying drawings and embodiments.

[0026] Example 1

[0027] like Figure 1 As shown, a small-sized convenient lettuce harvester comprises a main frame 1, a conveyor belt extracting device is arranged on the main frame 1, and a transmission device for driving the harvester is arranged on the main frame 1;

[0028] The conveyor belt extraction device includes a support frame 2, two sets of conveyor belts 3, and a conveyor motor 4. The support frame 2 is used to fix the conveyor belt 3 on the main frame 1, and the conveyor belt 3 is tilted. The highest side is connected to the conveyor motor 4, and the lower end of the lowest end is provided with a cutting device for cutting lettuce, wherein the cutting device is used to rotate at high speed to cut the lettuce so that the lettuce can be separated from the root and harvested smoothly. It can be in a variety of forms, such as chain saws, circular saws, compound cutters, circular knives, etc. According to the growth trend and mechanical properties of lettuce, the utility model adopts a large circular saw 8 to ensure the integrity of the cut product and the cutting process;

[0029] The conveyor belt 3 uses a customized PVC soft belt, a transmission drive wheel, and a transmission motor 4. In order to achieve the requirement of orderly transportation, the design adopts a flexible vertical conveyor belt machine, selects a green PVC soft conveyor belt, and has a semicircular wave 5-shaped symmetrical structure on both sides. The conveying power on each side is driven by a motor alone, and the two sides rotate relative to each other, which can not only gently support the lettuce to stand upright, but also have a push-pull force to prompt the lettuce to move to the operating platform, and the damage to the lettuce leaves is very small. The entire conveyor belt is divided into two sides, the two sides are the same but the motors are opposite in direction, and the two motors are located above the tail end of the conveyor belt, connected to the conveyor belt driving wheel, and a bearing is installed in the middle. The starting end of the conveyor belt adopts a driven wheel and is fixed on the frame. It can be adjusted slightly with the track to change the tightness of the conveyor belt. The upper end extends outward with a front end correction structure 7, so that the lettuce can be clamped on the conveyor belt smoothly and reduce the damage rate. The entire transmission mechanism can also use a horizontal climbing type conveyor belt, which only requires one motor, but it will increase the lettuce damage rate.

[0030] The transmission device adopts a tricycle assembly, a drum brake and gear-shifting integrated rear axle, which is equipped with a 700w motor. The power wheel adopts a solid tire of a construction tricycle, and the steering wheel adopts two universal wheels. The driving wheel is located at the rear to bear the load and provide power. The universal wheel is located at the oblique rear of the front circular saw to steer and protect the saw blade. The entire travel mechanism can adopt various forms, such as chain type, crawler type, etc. for different regions.

[0031] In this embodiment, the collecting frame 6 is located below the top of the conveyor belt 3. The lettuces are collected in the collecting frame 6 for storage and placement.

[0032] In this embodiment, a handrail 11 for pushing the harvester is provided on one side of the main frame close to the mobile phone frame.

[0033] The above embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the patent and protection scope of the utility model shall be subject to the attached claims.
