Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to a stalk remover for a tobacco stalk remover. Background Art

[0002] After the tobacco leaves are collected, the tobacco stems will remain in the tobacco planting area. If the tobacco stems are not processed, the pathogens in the tobacco stems will infect the crops planted in the future. Therefore, the tobacco stems need to be removed. The removed tobacco stems can be made into biomass fuel for baking tobacco leaves to achieve resource utilization.

[0003] In the related art, reference can be made to the Chinese utility model patent with authorization announcement number CN212876731U, which discloses a flue-cured tobacco rod pulling device, including a chassis and a hanging lug arranged on the top of the chassis, a power shaft is vertically arranged above the chassis, and a driving bevel gear is installed on the lower end of the power shaft after passing through the top of the chassis, a transmission shaft is horizontally arranged in the middle of the chassis, and a driven bevel gear meshing with the driving bevel gear is arranged in the middle of the transmission shaft, a reduction gear box is arranged on both sides of the chassis, and a pulling rod mechanism is arranged on one side below the chassis, the pulling rod mechanism includes a knife shaft and a plurality of annular plates fixed on the knife shaft, each annular plate is provided with two blades, and the two blades on the same annular plate are arranged at an angle of 180°, and the blades on each annular plate are staggered 45° from one end to the other end of the knife shaft along the same rotation direction.

[0004] It is connected to the traction machinery through the hanging lug and the traction machinery provides power. The power drives the transmission shaft to rotate through the power shaft, the active bevel gear and the driven bevel gear. After the speed change of the reduction box, the power is transmitted to the knife shaft through the transmission mechanism. The knife shaft drives the blade to rotate. The blade digs into the ground to a certain depth and continuously pulls up the tobacco rods during the rotation process to achieve the removal of the tobacco rods. However, the pulled out tobacco rods are rotated up by the action of the blades and fall irregularly in the tobacco field, which are easily covered by flying soil. At the same time, the fallen tobacco rods are easily squeezed and crushed by the wheels of the rod puller, which prolongs the subsequent collection time and thus reduces the efficiency of tobacco rod collection. Utility Model Content

[0005] In order to improve the efficiency of collecting tobacco stems, the utility model provides a tobacco stem remover for a tobacco stem removing machine.

[0006] The present application provides a tobacco stalk puller for a tobacco stalk puller, which adopts the following technical solution:

[0007] A tobacco stalk remover for a tobacco stalk removing machine comprises a connecting shaft and two removing rods arranged on the connecting shaft. The connecting shaft is used to connect with the stalk removing machine. The two removing rods are arranged on the connecting shaft relatively and extend forward. The distance between the two removing rods gradually increases from front to back.

When the rod pulling machine moves forward, it drives the two levers to move synchronously. The two levers correspond to two groups of tobacco stems respectively. The levers extend between the tobacco stems on the adjacent sides. As the rod pulling machine moves, the two levers distribute the two groups of tobacco stems to both sides of the rod pulling machine. The tobacco stems tend to fall outward under the action of the levers. Then, the tobacco stems are pulled up by the rod pulling mechanism of the rod pulling machine. The tobacco stems fall on both sides of the rod pulling machine under the action of their own gravity, which reduces the probability of tobacco stem damage and improves the convenience of subsequent collection of the tobacco stems, thereby improving the efficiency of tobacco stem collection.

[0009] Optionally, the connecting shaft extends horizontally, and the two shift rods are respectively arranged at two ends of the connecting shaft and extend downward from back to front.

[0010] By adopting the above technical solution, the lever extends forward, downward and inward, so that the front end of the lever can be located between the two groups of tobacco rods. As the rod pulling machine moves, the lever moves forward. As the distance between the two levers increases, the tobacco stems on the same side tilt outward under the action of the lever, thereby achieving the probability of the tobacco stems on the same side tilting in one direction, improving the convenience of subsequent removal and collection, and thus improving the efficiency of tobacco stem collection.

[0011] Optionally, a horizontal installation cavity is provided in the connecting shaft, and the shift rod is slidably disposed in the installation cavity through an adjustment component.

[0012] By adopting the above technical solution, the adjustment component is opened, and the lever is pulled to slide in the installation cavity, so as to adjust the distance between the two levers to adapt to the distance between the tobacco stems on both sides, thereby improving the convenience of removing the tobacco stems.

[0013] Optionally, two adjusting components are provided and correspond one to one with the shifting rods.

[0014] By adopting the above technical solution, the corresponding lever is selected for adjustment according to the position of the tobacco stem, thereby improving the convenience of adjusting the lever position.

[0015] Optionally, the adjustment component includes:

[0016] An adjusting rod, wherein the adjusting rod is horizontally arranged in the mounting cavity, and the shifting rod is fixedly arranged at an end of the adjusting rod away from the mounting cavity;

[0017] A positioning bolt is threadedly connected to the connecting shaft and an inner end of the positioning bolt abuts against the adjusting rod.

[0018] By adopting the above technical solution, the positioning bolt is rotated to disengage from the connecting shaft and the position of the adjusting rod is moved so that the distance between the front ends of the two levers is smaller than the distance between the tobacco stems on both sides, and the distance between the rear ends of the two levers is larger than the distance between the tobacco stems on both sides. The positioning bolt is then rotated to position the adjusting rod, thereby realizing the adjustment and positioning of the lever position, thereby improving the convenience of adjusting and positioning the lever.

[0019] Optionally, a plurality of the positioning bolts are provided, and the plurality of positioning bolts are distributed in sequence along the length direction of the connecting shaft.

[0020] By adopting the above technical solution, multiple positioning bolts improve the stability of the adjustment rod, thereby improving the stability of the lever during use.

[0021] Optionally, a reinforcement plate is provided between the adjusting rod and the shifting rod.

[0022] By adopting the above technical solution, the reinforcing plate improves the connection strength between the adjusting rod and the shifting rod, thereby extending the service life of the stalk shifter.

[0023] Optionally, the adjusting rod is a rectangular tube, and the longitudinal section of the mounting cavity is a rectangle.

[0024] By adopting the above technical solution, the adjusting rod is adapted to the installation cavity, and the rectangular structure improves the convenience and stability of the connection between the adjusting rod and the installation cavity.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. When the rod pulling machine moves forward, it drives two levers to move synchronously. The two levers correspond to two groups of tobacco stems respectively. The levers extend between the tobacco stems on the adjacent sides. As the rod pulling machine moves, the two levers shift the two groups of tobacco stems to both sides of the rod pulling machine. The tobacco stems tend to fall outward under the action of the levers, and then the rod pulling mechanism of the rod pulling machine is used to pull up the tobacco stems. The tobacco stems fall on both sides of the rod pulling machine under the action of their own gravity, reducing the probability of tobacco stem damage and improving the convenience of subsequent collection of the tobacco stems, thereby improving the efficiency of tobacco stem collection.

[0027] 2. The lever extends forward, downward and inward so that the front end of the lever can be located between the two groups of tobacco stems. As the lever pulling machine moves, the lever moves forward. As the distance between the two levers increases, the tobacco stems on the same side fall outward under the action of the lever, thereby achieving the probability of the tobacco stems on the same side falling in one direction, improving the convenience of subsequent removal and collection, and thus improving the efficiency of tobacco stem collection.

[0028] 3. Move the position of the adjusting rod so that the distance between the front ends of the two levers is smaller than the distance between the tobacco stems on both sides, and the distance between the rear ends of the two levers is larger than the distance between the tobacco stems on both sides. Then rotate the positioning bolt to position the adjusting rod, so as to adjust and position the lever position to adapt it to the distance between the tobacco stems on both sides, thereby improving the convenience of removing the tobacco stems.
