Problems solved by technology
[0002] Existing potato seedling killing machines are generally based on single-cutter rollers. After the cutting operation, the stems and leaves are scattered on the spot, and a large number of stems and leaves are mixed in the soil. When the potato harvester is operating in this way, a large number of stems and leaves are wrapped around the transmission rod and the transmission shaft. It is not conducive to the separation of potatoes and soil, causing the machine to be stuck and reducing the cleaning efficiency
The stems and leaves left after the potato harvest usually need to be cleaned up, and the operation method of spreading on the spot increases the workload of subsequent cultivation, which is not reasonable

Embodiment Construction
[0021] The present invention will be further described below with reference to the embodiments and the accompanying drawings. like figure 1 , figure 2 and image 3 As shown in the figure, a stubble-arranging type potato slaughtering machine, hereinafter referred to as a machine tool, includes a helical bevel gear transmission mechanism and a belt transmission mechanism. The power input helical bevel gear shaft 1 is in the forward direction. In addition, in order to enable stable and reliable deceleration input of power, the power input helical bevel gear shaft 1 meshes with the driven helical bevel gear 2 to form a gear pair, and the driven helical bevel gear 2 is non-rotatably sleeved on the pulley driving shaft 3 .
[0022] See Figure 5 , Image 6 and Figure 7 , the belt transmission mechanism includes a left driving pulley 4a and a right driving pulley 5a that are non-rotatably sleeved on both ends of the pulley driving shaft 3, and the left driving pulley 4a and t...

The invention discloses a stubble discharging type potato seedling killing machine, which comprises an oblique bevel gear transmission mechanism, a belt transmission mechanism, a flail knife roller and a bidirectional spiral stranding cage, and is characterized in that power is efficiently input through tooth transmission, is reliably shunted through a belt transmission system with system protection, and is respectively transmitted to the flail knife roller and the bidirectional spiral stranding cage; the flail knife roller rotates to kill seedlings, and then crushed stubbles are conveyed to the two sides of the machine tool through the bidirectional spiral stranding cage. By the adoption of the scheme, transmission efficiency is high, the structure is simple, stable and reliable, seedling killing operation can be completed, broken stems and leaves can be discharged and conveyed to the two sides, broken stubbles in soil are reduced, secondary tillage is facilitated, and the cleaning efficiency during potato harvesting can be greatly improved.
Description
technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a machine specially used for returning potato leaves to the field. Background technique [0002] Existing potato rice harvesters are generally based on single-knife rollers. After cutting, the stems and leaves are thrown on the spot, and a large number of stems and leaves are mixed with the soil. When the potato harvester operates in this way, a large number of stems and leaves are entangled on the transmission rod and the transmission shaft. It is not conducive to the separation of potatoes and soil, causing the machine to be stuck and reducing the cleaning efficiency. The stems and leaves left after the potato is harvested usually need to be cleaned and unearthed, and the operation method of throwing on the spot increases the workload of subsequent farming, which is not reasonable. [0003] The inventor's team found in the research that the use of the dual-shaft...
