Technical Field

The invention relates to the field of tobacco field planting, in particular to a tobacco field stalk pulling machine.

Background

Tobacco plants only remain the tobacco stems on the tobacco ridges after the upper leaves are harvested, and for the transplantation of the tobacco plants in the second year, the tobacco stems on the tobacco ridges need to be pulled out, and meanwhile, the tobacco ridges are pushed flat to wait for the ridging again in the second year. Tobacco stem pulls out among the prior art and mostly goes on through the manual work, and tobacco grower pulls out the tobacco stem in order and abandons in the field along the tobacco ridge more, treats that the pull rod operation is unified after accomplishing and collects again, and not only intensity of labour is big, and the follow-up of tobacco stem all adopts to burn or landfill to handle moreover, causes the waste of resource.

Also there are more dead man machines among the prior art, but the structure is comparatively complicated and each mechanism all needs drive fit, especially adopts the dead man mechanism of grid cylinder type, because the tobacco rod is highly great and hardness is higher, so often the volume of this type of machinery also need design bigger dead man operation in order to adapt to the tobacco rod, this just causes the cost higher and also has higher requirement to the operation topography, more is applicable to the operation of the level land piece in plain area. However, the tobacco planting area is mostly in the mountain area, which makes it difficult for large-scale machinery to realize high-efficiency operation.

The utility model discloses a cigarette ridge, including the fixing rod, the fixing rod is fixed on the fixing rod, and the fixing rod is fixed on the fixing rod. Thereafter, along with the continuous rotation of the rotary drum, the ejector rod enters the large-radius curved surface part of the radial section of the fixed rod, so that the ejector rod moves outwards in the radial direction, the hinged rod drives the two sliding blocks to move oppositely, and then the two clamping arms are pulled to move oppositely and clamp the tobacco rod. Along with the rotation of the rotary drum and the movement of the moving vehicle, the two clamping arms still keeping clamping can smoothly pull out the tobacco stems from the soil and turn the tobacco stems to enable the tops of the tobacco plants to move downwards to the crushing box. Simultaneously, when the ejector pin contacted in order and left the curved surface lug, can produce the displacement of high-frequency for the tobacco rod of two arm lock centre grippings produces violent shake, and then shakes the soil attached with the tobacco rod root and leaves, effectively prevents that the soil of tobacco plant root from getting into crushing case.

Along with the continuation rotation of rotary drum, the centre gripping cigarette rod's centre gripping frame ejector pin is about to get into the top of semi-ring recess, and arm lock pine open position department promptly, thereafter along with the continuation rotation of rotary drum, thereby the ejector pin gets into the less radius curved surface portion of dead lever radial cross-section and moves towards the dead lever radial under the effect of spring, and two sliders keep away from dorsad, and then two arm locks of pulling keep away from dorsad and loosen the cigarette rod, and the cigarette rod can get into crushing case smoothly and smash under the pulling of crushing roller. Simultaneously adjacent holding frame of circumference range carries out the centre gripping to the tobacco rod on the adjacent ridge, circulation operation so, along with the removal of locomotive, the coulter frame that arrives afterwards can effectively push away the level and loose ground operation to the tobacco ridge that exceeds ground.

When the tobacco rod drops into crushing inslot portion through the feed inlet, the second motor drives first crushing roller and rotates, and first crushing roller drives the second through the meshing between the drive gear and smashes the roller and rotate to opposite direction, makes first crushing roller smash the roller with the second and smashes the tobacco rod, and the tobacco rod gathering after smashing is smashing the bottom half portion, waits to concentrate the discharge and is collected.

It should be noted that the distance design of the pull rods is related to the planting distance of tobacco plants, the distance between circumferentially adjacent clamping frames is related to the planting distance of tobacco ridges, and the moving speed of the moving vehicle needs to be taken into consideration to ensure that each circumferential clamping frame works in sequence.

Compared with the prior art, the invention has the following advantages: the tobacco stem smashing machine is simple in structure, can effectively pull out and smash tobacco stems and push tobacco ridges flatly and loosen the soil, greatly saves labor consumed by tobacco leaf planting, meanwhile, unifies and collects the tobacco stems, and improves the later-period utilization rate of the tobacco stems.
