Embodiment Construction
[0023] The specific implementation manners of the present invention will be further described in detail below in conjunction with the drawings and embodiments.
[0024] Such as figure 1 and 2 As shown, the stalk clamping device of the cassava harvester according to the present invention consists of a stalk introduction part 1, a clamping motion sensor 2, a mounting frame 3, a clamping part 4, a lower linkage rod 5, and a right drive connecting rod 6 , drive cylinder 7, left drive connecting rod 8, pressure relay 9 and upper linkage rod 10. The top of mounting bracket 3 is provided with four connection holes 11, and the present invention can be installed on the tuber root pulling mechanism or device of cassava harvester by bolt. The stem introduction part 1 is made by bending an iron rod to form three triangular openings of the same size. The sum of the sizes of the three triangular openings is equal to two times the maximum ridge eccentricity of cassava stems at 20cm from th...

The invention discloses a stalk clamping device of a cassava harvester. The clamping device of the cassava harvester comprises a mounting rack, a stalk guide component, clamping components, a clamping action sensor, a driving oil cylinder, a left driving connecting rod, a right driving connecting rod, an upper linkage rod, a lower linkage rod and a pressure relay. The stalk guide component is welded at the front portion of the mounting rack and the clamping action sensor is mounted at the front portion of the mounting rack. The driving oil cylinder as a driving source is installed at the rear portion of the mounting rack and the clamping components are mounted at the middle portion and the lower portion of the mounting rack. Two connected parallel four-bar mechanisms are formed by left half parts of the clamping components, the mounting rack and the upper linkage rod. Two connected parallel four-bar mechanisms are formed by right half parts, the mounting rack and the lower linkage rod. A parallel four-bar mechanism is formed by left half parts and right half parts in the middle positions of the clamping components. By utilization of the stalk clamping device of the cassava harvester, the problems that in an existing clamping pluck-up device of a clamping-chain type, clamping force is excessive large or small, misses clamping, is blocked or stalks are clamped to be broken to pieces can be solved.
Description
technical field [0001] The invention relates to an agricultural machine, in particular to a stem clamping device of a cassava harvester. technical background [0002] At present, there are two main forms of cassava harvesters with a high degree of mechanization. One is a digging cassava harvester composed of a digging loosening device and a vibration separation device to realize cassava root excavation and soil and potato separation, and the other is a digging shovel. It is composed of a cassava root clamping and pulling device, which is a digging and pulling cassava harvester for loosening the soil around the cassava root and pulling up the cassava root. Both types of cassava harvesters require the cassava stalks to be cut off and removed from the field before work. The difference is that the latter cassava harvester requires the cassava stalks to be cut off at a distance of about 30 cm from the ground, while the former requires There are no special requirements for cassav...
