Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and more particularly to a device for preventing a tobacco stalk pulling roller from being stuck with mud and entangled with grass. Background Art

[0002] The invention patent with the announcement number CN116210451A discloses a stalk pulling cone roller and a tobacco stalk pulling machine. The stalk pulling cone roller includes a front end of a power output shaft installed in a stalk pulling transmission box, which is driven to rotate by the power output shaft of the stalk pulling transmission box. Four cage-shaped cone rollers are arranged horizontally and have equal rotation speeds. The cage-shaped cone rollers are divided into two groups, upper and lower, with their axes parallel to each other. Each group of cage-shaped cone rollers is high in the front and low in the back, and symmetrical on the left and right sides, but the left and right cone rollers rotate in opposite directions. When the tobacco stalks are fed into the left and right stalk pulling cone rollers, as the stalk pulling machine moves forward, the tobacco stalks are wedged between the rotating left and right cone rollers, and the friction between the left and right stalk pulling cone rollers and the tobacco stalks is used to pull the tobacco roots out of the soil, and the tooth plates of the upper and lower stalk pulling rollers are used to squeeze the tobacco roots in turn to clean the soil at the tobacco roots. Compared with the traditional rotary knife-type tobacco root-digging stalk pulling device, the stalk pulling cone roller has low power consumption, and the tobacco stalks are thrown backward and upward after being pulled out, which saves the picking process for subsequent processing of the tobacco stalks.

[0003] However, the above-mentioned stalk pulling machine still has certain problems in use. If the stalk pulling operation encounters weeds and sticky soil with good soil moisture, the stalk pulling rollers are prone to sticking to mud and weeds. The diameter of the stalk pulling roller is getting larger and larger, causing the rotation resistance of the stalk pulling roller to increase sharply, and the gap between the left and right stalk pulling rollers is getting larger and larger, resulting in failure of the stalk pulling machine. It is necessary to stop the machine and manually clear the mud and weeds adhered to the stalk pulling rollers. This problem seriously affects the reliability and stalk pulling efficiency of the stalk pulling machine.

[0004] Therefore, it is an urgent problem for those skilled in the art to develop a device for preventing tobacco stalk pulling rollers from sticking mud and being entangled with weeds, which has high construction efficiency and can avoid the adhesion of mud and entanglement of weeds. Summary of the invention

[0005] In view of this, the present invention provides a device for preventing tobacco stalk pulling rollers from being stuck to mud and entangled with weeds, which can avoid the adhesion of mud and entanglement of weeds and has high construction efficiency.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] A device for preventing a tobacco stalk pulling roller from being stuck with mud and entangled with grass, comprising:

[0008] Floating gearbox,

[0009] A stalk pulling roller, the stalk pulling roller is fixedly connected to the output end of the floating transmission box; the tobacco stalk is clamped between two adjacent stalk pulling rollers and is clamped and pulled out;

[0010] A scraper is fixed to one end of the floating transmission box connected to the stalk pulling roller and is located on a side of the stalk pulling roller away from clamping the tobacco stems.

[0011] The beneficial effect of adopting the above technical solution is that, during the rotation of the stalk pulling roller in the present invention, the scraper will cut and remove the soil adhered to the stalk pulling roller or the entangled weeds, thereby improving the reliability of the stalk pulling roller.

[0012] Preferably, the output end of the floating transmission box is provided with an anti-weed entanglement disc, and the anti-weed entanglement disc is provided outside the connection between the output shaft of the floating transmission box and the central shaft of the stalk pulling roller, and the anti-weed entanglement disc completely covers the exposed part of the end of the central shaft of the stalk pulling roller. The anti-weed entanglement disc is fixed relative to the stalk pulling roller, and the weeds lose the power to entangle on the central shaft of the stalk pulling roller on the anti-weed entanglement disc, which can solve the problem of weed entanglement on the central shaft of the stalk pulling roller.

[0013] Preferably, a bearing cover is provided at the output end of the floating transmission box, and the anti-grass entanglement disc is fixedly connected to the bearing cover.

[0014] Preferably, the floating transmission box comprises: a left floating transmission box and a right floating transmission box; the left floating transmission box and the right floating transmission box are arranged in parallel and each has two output shafts; the stalk pulling rollers are provided on the output shafts of the left floating transmission box and the right floating transmission box.

[0015] Preferably, the scraper is V-shaped, and is located between the upper and lower stalk pulling rollers of the left floating transmission box or the right floating transmission box, and the two blades of the scraper are respectively facing the upper and lower stalk pulling rollers. The shape and setting position of the scraper can ensure that one scraper can remove the soil or weeds on the two stalk pulling rollers at the same time.

[0016] Preferably, a blade holder is fixed to the outside of the scraper along its length direction. The provision of the blade holder can improve the stability of the scraper during use.

[0017] Preferably, a fixing plate is fixed to one end of the tool holder close to the left floating transmission box or the right floating transmission box, and the fixing plate is fixedly connected to the side wall of the left floating transmission box or the right floating transmission box.

[0018] Preferably, the input ends of the left floating transmission box and the right floating transmission box are provided with fixed transmission boxes, the two output ends of the fixed transmission box are respectively connected to one of the input ends of the left floating transmission box or the right floating transmission box, the fixed transmission box is arranged in an inclined shape, and the left floating transmission box, the right floating transmission box and the fixed transmission box are arranged in an N shape.

[0019] Preferably, the input end of the fixed transmission box is connected to the hydraulic motor.

[0020] Preferably, both ends of the left floating transmission box and the right floating transmission box are connected by a tension spring.

[0021] It can be seen from the above technical solutions that, compared with the prior art, the present invention discloses a device for preventing tobacco stalk pulling rollers from being stuck with mud and entangled with grass, wherein the beneficial effects are:

[0022] (1) In the present invention, without changing the structure of the original stalk pulling machine, the relative rotation of the stalk pulling roller and the scraper is utilized to clamp the tobacco stalks on the inner side of the stalk pulling roller and cut off the mud and weeds adhering to and entangled on the stalk pulling roller on the outer side, thereby ensuring that the stalk pulling roller will not be stuck with mud or entangled with weeds when working continuously for a long time;

[0023] (2) The anti-weed entanglement disc is fixed relative to the stalk pulling roller, and the weeds lose the power to entangle on the central axis of the stalk pulling roller on the anti-weed entanglement disc, which can solve the problem of weed entanglement on the central axis of the stalk pulling roller;

[0024] (3) The present invention does not require a dedicated external power mechanism to drive the tobacco stalk pulling roller to prevent mud and grass entanglement, and has a simple structure and is durable. BRIEF DESCRIPTION OF THE DRAWINGS
