A rapeseed threshing and chopping machine

Abstract

The invention discloses a rape threshing and chopping integrated machine. The rape threshing and chopping integrated machine comprises threshing drums arranged on a machine frame, a straw chopping mechanism arranged on the machine frame, and a plurality of groups of compression rollers arranged on the machine frame; the passageways between the threshing drums and the compression rollers are connected by a sieve plate for only allowing rapeseeds to sieve out, the head end of the sieve plate is an inlet for feeding rape, and the lower side of the sieve plate is a hopper provided with a rapeseedoutlet; the straw chopping mechanism is arranged at the end of the sieve plate, the straw chopping mechanism includes a stationary knife fixed at the end of the sieve plate and movable knives capableof performing cutting movement relative to the stationary knife, at least one group of the compression rollers are arranged in front of the straw chopping mechanism, and the straw chopping mechanism is connected with a chopped straw outlet. The rape threshing and chopping integrated machine does not need to cooperate with a rape combine harvester for harvesting, is capable of ensuring the rape threshing effect, and the rape straw treatment after threshing is convenient, therefore, the rape threshing and chopping integrated machine has good application prospect for harvesting of rape in dispersed cultivation.

Description

technical field [0001] The invention belongs to a rapeseed threshing machine, in particular to a rapeseed threshing and chopping machine. Background technique [0002] Due to the special agronomic requirements of rapeseed, many rapeseed harvesters currently on the market adopt the combined harvesting mode. However, due to the particularity of rapeseed pods, if the harvest time is early in the field, it will be difficult to thresh, and the seeds are not mature enough. It is not clean and the production efficiency is low. The harvest time is late. After the rape pods are fully ripe, the rapeseeds will fall off when touched. Combined harvesting has a large loss of threshing, and it is easy to affect production efficiency. [0003] In addition, there is another rapeseed harvesting mode. The rapeseed stalks are harvested and concentrated in the air, and the rapeseed pods are dried and matured before being threshed by a thresher. Scattered and difficult to handle, causing difficu...

[0002] Due to the special agronomic requirements of rapeseed, many rapeseed harvesters currently on the market adopt the combined harvesting mode. However, due to the particularity of rapeseed pods, if the harvest time is early in the field, it will be difficult to thresh, and the seeds are not mature enough. Unclean and low production efficiency; the harvest time is late, and when the rape pods are fully ripe, the rapeseeds will fall off as soon as they are touched. Combined harvesting will result in large threshing losses, which will easily affect production efficiency

[0003] In addition, there is another rapeseed harvesting mode. The rapeseed stalks are harvested and concentrated in the air, and the rapeseed pods are dried and matured before being threshed by a thresher. Scattered and difficult to handle, causing difficulties in the handling of rapeseed straw
