During operation, the bamboos are stuffed between the upper roller and the lower roller by the inlet ends of the through grooves (namely the front sides of the through grooves), and are conveyed to the outlet ends of the through grooves (namely the rear sides of the through grooves) under the driving of the conveying assembly. Preferably, the middle parts of the upper roller and the lower roller are both provided with concave arc shapes to avoid the bamboo from swinging left and right during the conveying process (see fig. 9).

The upper machine frame is movably connected with the lower machine frame through a shape following spring 6, and the distance between the upper roller and the lower roller can be automatically adjusted according to the diameter of the bamboo so as to adapt to the bamboos with different thicknesses (see figure 8). The upper rack is provided with three weight boxes, the weight blocks (not shown in the figure) with proper quantity can be placed in the weight boxes, the upper rack presses the shape following spring through the gravity provided by the weight blocks, the upper roller and the lower roller can be tightly attached to the surface of the bamboo, the bamboo is clamped, and the subsequent branch removing and bamboo breaking operation of the bamboo is facilitated.

The conveying assembly is used for driving the bamboos to be conveyed between the upper roller and the lower roller; the conveying assembly comprises a plurality of (four in the figure) rotating shafts 3-1 and a power source 3-2. The rotating shafts are parallel to each other (perpendicular to the conveying direction of the bamboos) and can be rotatably positioned on the lower rack. All the rotating shafts are sequentially connected in a transmission way through a chain wheel and chain pair; one of the rotating shafts is used as a driving shaft and driven by a power source; a manual power source (such as a rotating handle) or an electric power source (such as a driving motor) can be adopted according to actual conditions. In this embodiment, the two ends of the rotating shaft as the driving shaft are supported by vertical bearing blocks 3-3 fixed on the lower frame, and the two ends of the other rotating shafts are supported by rhombic bearing blocks 1-3 fixed on the lower frame. Among four pivots, wherein two pivots respectively with lead to the coaxial fixed connection of two lower rollers of groove entry end and lead to the groove exit end, can provide main power for the bamboo at leading to the groove entry and lead to the groove exit, guarantee the smooth transport of bamboo.

As shown in fig. 4 to 6, the delimbing assembly is inserted between the upper roller and the lower roller to delimbing the bamboo. The delimbing components comprise two groups of upper delimbing components 4-1 which are obliquely arranged on the upper rack and lower delimbing components 4-2 which are vertically arranged on the lower rack.

first, a proper amount of weight blocks are put in the upper machine frame, the shape following springs are compressed, and a proper gap is reserved between the upper roller and the lower roller. Then, the power source is driven, and power is input to the whole machine through the conveying assembly. At last, the root of the bamboo (namely the thick and big end of the bamboo) is plugged in by the inlet end of the through groove, the lower roller of the inlet end of the through groove is automatically rolled into the machine through friction force, and the upper and lower rollers can adapt to the shape of the big end of the bamboo under the automatic adjustment action of the shape-following spring and the balancing weight.

The bamboo is conveyed between the upper roller and the lower roller, the root of the bamboo firstly reaches the position of the bamboo breaking knife, and the bamboo breaking knife breaks the bamboo at the root of the bamboo. After the root of the bamboo is broken by a certain length, one end of the bamboo with branches enters the working range of the branch removing assembly, the roller on the cutter shaft firstly contacts the surface of the bamboo, and under the action of the second spring, no matter how the diameter of the bamboo changes, the roller always supports against the surface of the bamboo, and smooth conveying of the bamboo at the branch removing assembly is guaranteed. In addition, because the branch removing knife is at a certain distance from the surface of the bamboo, the branches and the branch removing knife move relatively in the conveying process of the bamboo, and the purpose of branch removing is achieved.

At the last segment after the bamboo breaks open, the bamboo only provides the lower roll of leading to the groove exit end and carries main power, and the bamboo can't normally be told from leading to the groove exit end, can apply the manpower and easily tear the bamboo from leading to the groove exit end. And then putting the broken bamboos aside, and waiting for the batch of bamboos to be packaged.
