Technical field

The utility model relates to a kind of machinery with fruit and cane disengaging, and especially a kind of green soybean huller belongs to agricultural machinery technological field.

Background technology

Understand according to the applicant, for a long time, the pod that takes off of soybean (green soy bean) relies on manual operations all the time, and efficient is low, and labour intensity is big.Retrieval is found; though be useful on the patent application of legume crop threshing; for example application number is that 90204717.5 Chinese patent application discloses a kind of " beans thresher ", and the threshing cylinder of this machine is made of with not being connected on two different circumference of threshing cylinder disk with the threaded rod of spike-tooth the threaded rod of threaded spike-tooth.In addition; application number is that the Chinese patent application of 200620022454.X discloses a kind of " soybean thresher "; this equipment comprises charging aperture, threshing chamber, discharge chamber, slide plate and discharging opening; between threshing chamber and discharge chamber, screen cloth is arranged; on the opening of discharge chamber side air exhauster is arranged; rotating shaft is arranged in the threshing chamber, rake teeth is arranged in the rotating shaft, rotating shaft and air exhauster all by belt, by driven by motor.Yet these prior aries all are not suitable for the pod that takes off of soybean.

The utility model content

The purpose of this utility model is: propose a kind of green soybean huller, thereby realize that soybean takes off the mechanized of pod, raise the efficiency, reduce labor intensity.

In order to reach above purpose, green soybean huller of the present utility model comprises frame, and described upper rack is provided with the carrier chain that along continuous straight runs is sent to, and the bottom is provided with cleaning fan; The middle part of described carrier chain is equipped with rotation and is taken off the pod device; Wherein, described carrier chain is positioned at one side of frame, constitutes the clamping conveying mechanism with the clamping pressing plate that is positioned on the carrier chain; The described pod device that takes off is made of the upper and lower pod roller that takes off that at least one pair of is supported on clamping conveying mechanism inboard, has flexibility spaced apart and that radially extend on the described roll shaft that takes off the pod roller and takes off the pod tooth, and the axis and the throughput direction of described roll shaft are angle; It is interlaced that described upper and lower flexibility of taking off the pod roller is taken off the pod tooth.

During work, beans bar one end that does not take off pod is placed the clamping conveying mechanism of carrier chain and clamping pressing plate formation, progressing into upper and lower two with the motion of carrier chain takes off between the pod roller, taking off the pod tooth in staggered flexibility impacts under the effect, beanpod comes off from the beans bar one after another, in the process of dropping, the beans leaf that cleaning fan drops blowing, thus finish the mechanized that soybean takes off pod.

The utility model further improves, and described the first and second two pairs of taking off that clamp device distributes by front and back take off the pod roller and constitute, and described first takes off the roll shaft axis of pod roller and the angle of throughput direction takes off the roll shaft axis of pod roller and the angle of throughput direction less than second.Like this, the beans bar that does not take off pod takes off the pod tooth through the flexibility of secondary different directions and impacts in course of conveying, can further improve the pod rate of taking off.

The utility model further improves, and the pod place that falls, described frame bottom is provided with vibration sorting screen, takes off the beanpod that drops behind the pod through cleaning, and can screen out the full beanpod of shrivelled reservation, saves the artificial screening that takes off behind the pod, further improves mechanization degree.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Embodiment

Embodiment one

The green soybean huller of present embodiment as depicted in figs. 1 and 2, top one end of frame 9 is a bin 3, one side next-door neighbour's bin 3 of frame is provided with the carrier chain 1 that along continuous straight runs is sent to, this carrier chain constitutes by the drive sprocket 10 that is supported on the frame two ends respectively and driven sprocket 11 and around the chain 12 of two sprocket wheels, it is hook-shaped depression bar device 14 that the cross section is equipped with in driven sprocket 11 tops, form spout 2 between this depression bar device and the chain, the clamping pressing plate 13 that bears spring 15 active forces is housed on the frame on the carrier chain 1, and the chain 12 of carrier chain and the clamping pressing plate that matches with it 13 constitute the clamping conveying mechanism.

The middle part of carrier chain 1 is equipped with rotation and is taken off the pod device, taking off the pod device is made of the first and second two pairs of upper and

lower pod rollers

5,5 ' and 6,6 ' that take off that are supported on clamping conveying mechanism inboard, respectively take off and have rubber spaced apart and that radially extend on the roll shaft of pod roller and take off the pod tooth, first pair is taken off the axis of pod roller 5,5 ' roll shaft and about 45 ° of the angle (45 ° ± 5 °) of throughput direction, and second pair is taken off the axis of pod roller 6,6 ' roll shaft and about 70 ° of the angle (70 ° ± 5 °) of throughput direction.It is interlaced that each upper and lower flexibility of taking off the pod roller is taken off the pod tooth.

The bottom of frame 9 is provided with cleaning fan 4 and the funnel-form pod inclined-plane 20 that falls, and the bottom on the pod inclined-plane 20 that falls is provided with vibration sorting screen 7.Motor 8 is settled in one side of vibration sorting screen 7, the output shaft of this motor is in transmission connection with the rotating shaft of taking off pod device driving shaft 17 and cleaning fan 4 respectively by driving-belt, the rotating shaft of cleaning fan 4 is in transmission connection by driving-belt and vibration sorting screen 7, and vibration cleaning screen 7 power shafts one end drives clamping by chain by chain again through reducer of turbodrill and carries drive sprocket 10.

Taking off pod device driving shaft 17 is in transmission connection with two pairs of following pod rollers 5 ' and 6 ' that take off that take off in the pod roller respectively by two pairs of

bevel gear pairs

18,19; Take off down pod roller 5 ' and 6 ' respectively the driving-chain by its end with corresponding on take off pod

roller

5 and 6 and be in transmission connection.

When taking off the pod operation, the beans bar that takes off in the future pod is laid on the bin, after pressing together through the depression bar device, one end of beans bar enters in the clamping conveying mechanism of carrier chain and clamping pressing plate formation, the shaft of band beanpod progresses into first upper and lower two of inclination with the motion of carrier chain and takes off between the pod roller, take off under the effect that impacts incremental to the tip of pod tooth in staggered flexibility by root, beanpod comes off from the beans bar one after another, afterwards through second upper and lower two the taking off between the pod roller of translation-angle, remain in beanpod on the beans bar and further impacted and come off.In the process of dropping, cleaning fan is with the beans leaf that the drops frame of blowing off, and the beanpod of falling on the vibration sorting screen screens out flat pod in vibration, stay full beanpod, thereby finishes the mechanized that soybean takes off pod.

Facts have proved that the green soybean huller of present embodiment is rational in infrastructure, transmission is simple and direct, high efficiency, and it is good to take off the pod quality, can significantly reduce labor intensity.In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
