See fig. 1-8. The flue-cured tobacco straw recovery device described in the embodiment is used for recovering flue-cured tobacco straw in a tobacco field, and the straw is left in the tobacco field after tobacco leaves are harvested from flue-cured tobacco planted by a tobacco grower. Because the straw and root system may have virus, the flue-cured tobacco straw needs to be pulled out and transported to the place of the tobacco field.

In this embodiment, the flue-cured tobacco straw recycling device is a movable device, such as a walking mechanism, or a tractor connected through a connecting mechanism. The running mechanism and the tractor are not shown in the drawing of the embodiment, but the running mechanism and the traction mechanism belong to the mature technology in the prior art. For example, the running gear may be a hand tractor and the tractor may be an agricultural tractor. However, in the prior art, a machine which facilitates the movement of the flue-cured tobacco straw recovery device in the tobacco field without creative labor can be adopted.

The flue-cured tobacco straw recycling device comprises a power transmission mechanism, and in the utility model, the power transmission mechanism is used for transmitting mechanical energy to the driving wheel 112; in a preferred embodiment, mechanical energy is also transferred to the beater; in a preferred embodiment, mechanical energy is also transferred to the comminution mechanism. Generally, an electric motor or a diesel engine is used as a power source in the field, a power output end of the electric motor or the diesel engine rotates at a high speed, and a power transmission mechanism converts the high-speed rotation of the power output end of the electric motor or the diesel engine into low-speed rotation or reciprocating linear motion or vibration of other mechanisms or parts. The specific structural form of the power transmission mechanism is not unique, and the gear mechanism, the belt wheel mechanism, the worm mechanism, the connecting rod mechanism and the like in the prior art can be used for transmitting motion and changing the motion relation. In the present embodiment, the power transmission mechanism is installed in a chassis, and in the present embodiment, the chassis includes a main chassis 100, and in a preferred embodiment, further includes a first chassis 201, and in a further preferred embodiment, further includes a second chassis 301. The first casing 201 is installed in front of the main casing 100, and the second casing 301 is disposed at the rear of the main casing 100.

The flue-cured tobacco straw recovery device of the embodiment further comprises a rack 101 and a pulling rod mechanism. The lever mechanism includes a first clamping assembly 110 and a second clamping assembly 120 disposed opposite to each other. In this embodiment, the first clamping assembly 110 and the second clamping assembly 12 are disposed facing thereto. A straw conveying channel is formed between the first clamping assembly 110 and the second clamping assembly 120, and clamped straws move from the front end to the rear end under the clamping action of the two clamping assemblies. The first clamping assembly 110 and the second clamping assembly 120 correspond to two longitudinally arranged conveyor belts, and a material conveying route is arranged between the two conveyor belts. Specifically, the first clamping assembly 110 includes a first clamping belt 111, a driving wheel 112 and a driven wheel, and the first clamping belt 111 is in transmission fit with the driving wheel 112 and the driven wheel. In this embodiment, the first clamping assembly 110 includes two driven wheels, including a first driven wheel 113 and a second driven wheel 114. The driving pulley 112, the first driven pulley 113 and the second driven pulley 114 are arranged in a triangular layout and are mounted on the frame 101. The second clamping assembly 120 is disposed in a plane-symmetric manner with respect to the first clamping assembly 110, and is also mounted on the frame 101. Referring to fig. 2 and 3, the inlet of the straw conveying channel is open, so that the tobacco straw recycling device can conveniently and rapidly enter the straw conveying channel in the forward process. Although the tobacco plants on the ridges are arranged regularly and uniformly when the flue-cured tobacco seedlings are transplanted, the situation that the individual flue-cured tobacco straws incline is difficult to avoid. Through setting up uncovered, can income straw transfer passage with all upright flue-cured tobacco straw. Taking fig. 2 as an example, the first clamping belt of the first clamping assembly 110 rotates counterclockwise, and the clamping belt of the second clamping assembly 120 rotates clockwise, that is, in the straw conveying passage, the first clamping belt of the first clamping assembly 110 and the clamping belt of the second clamping assembly 120 move in the same direction.

Referring to fig. 2, the base plate 101 is a fork-shaped plate, and includes two mounting arms for mounting the first clamping assembly 110 and the second clamping assembly 120, respectively, and a cross beam 102 is disposed between the two mounting arms, and the cross beam 102 is perpendicular to the straw conveying passage. The beam 102 is used to support flue-cured tobacco straw. When pulling out the straw, flue-cured tobacco straw recovery unit is marchd forward, and the dead man mechanism pulls the flue-cured tobacco straw backward, and crossbeam 102 provides a holding power to the flue-cured tobacco straw. Flue-cured tobacco straw is pulled out from soil by flue-cured tobacco straw recovery unit under the combined action of dead man mechanism and crossbeam 102. In order to increase the force between the first clamping belt 111 and the straw, teeth 115 are provided on the first clamping belt 111.

In a preferred embodiment, a mud scraper 200 is installed below the frame 101, and the mud scraper 200 is connected to the first housing 201. The mud beater is a vibrating rod or a rotary drum. Fig. 2, 4 and 8 show the case that the beater is a rotating drum. When the beater is a vibrating rod, a transmission mechanism, such as a cam mechanism, vibrates the vibrating rod to shake off the soil at the root of the straw. When the mud beater is a rotary drum, a plurality of cross rods are arranged on the periphery of the rotary drum, the rotary drum is rotated by the transmission mechanism, and the cross rods collide with the root of the straw to enable the soil at the root of the straw to fall. As shown in fig. 8, the beater 200 is below and forward of the beam 102.

As a further implementation manner, flue-cured tobacco straw recovery unit still includes rubbing crusher 300 and feed bin 400 in this embodiment, and rubbing crusher 300 is used for smashing the straw to use feed bin 400 to collect the straw after smashing, so that transport after the compression. The crushing mechanism 300 is installed at the outlet of the straw conveying channel, and straws are crushed for the first time when passing through the lever pulling mechanism, namely, the straws are broken under the clamping action of the two clamping belts. The cracked straw comes out of the straw conveying passage and is crushed by the crushing mechanism 300. The crushing mechanism 300 is a mechanism for crushing straw, such as a propeller type cutter or a drum type cutter. The propeller type cutter is a cutter set with blades replacing propeller blades, and straws are cut into particles when passing through the blades rotating at a high speed. Referring to fig. 8, in the present embodiment, the crushing mechanism 300 is a drum type cutter, the crushing mechanism 300 is installed on the second casing 301, and the transmission mechanism makes the crushing mechanism 300 rotate rapidly, in the present embodiment, the drum type cutter is installed with a plurality of cutters between two circular plates, and specifically, in the present embodiment, a thin steel wire is used as the cutter.
