Description

Technical Field

[0001] The utility model relates to a tobacco field weeding device, belonging to the technical field of ridge ditch weeding. Background Art

[0002] Tobacco is planted in the middle of the ridge. During the growth of tobacco, in order to ensure the quality of tobacco growth, it is often necessary to weed the ridge surface. At present, weeding methods include manual, chemical, physical, mechanical, biological and ecological weeding methods. Among them, chemical weeding in tobacco fields is still the main weeding method. Since it can reduce the amount of pesticides used, or even eliminate the use of pesticides, mechanical weeding has become a widely accepted weeding method after chemical weeding.

[0003] The existing document (CN220653939U) discloses a tobacco field ridge weeding device, which includes: a mobile frame; a running wheel, which can be rotatably mounted on the front bottom of the mobile frame; a weeding knife, which is fixedly connected to the rear bottom of the mobile frame, and the weeding knife is in a curved arc shape, which matches the cross-sectional shape formed by the tobacco field ridge and the ridge surfaces on both sides, and the front edge of the weeding knife is a blade. This scheme combines the mobile frame, the running wheel and the weeding knife into a weeding device, and the weeding knife is designed to be a curved arc shape that matches the cross-sectional shape formed by the ridge and the ridge surfaces on both sides, so that the weeds on the ridge and the ridge surfaces on both sides can be removed at one time. However, in actual production, the applicant found that the weeding device is inconvenient to operate, and stones are more likely to damage the blade during the weeding process. Utility Model Content

[0004] Based on the above, the utility model provides a tobacco field weeding device that is easy to operate to overcome the deficiencies of the prior art.

[0005] The technical solution of the utility model is: a tobacco field weeding device, comprising:

[0006] A supporting unit, comprising a running wheel, a fixed shaft and a connecting rod, wherein the running wheel is rotatably mounted on both ends of the fixed shaft, and one end of the connecting rod is arranged at the middle of the running wheel;

[0007] The weeding unit comprises an operating rod and a weeding knife, wherein the weeding knife is arranged at the bottom end of the operating rod, the other end of the connecting rod is connected to the upper part of the lower section of the operating rod, and the angle between the operating rod and the connecting rod is an obtuse angle.

[0008] In one example, a stop rod is provided at the bottom of the fixed shaft and between the two traveling wheels.

[0009] In one example, the connecting rod is in an upwardly curved arc shape.

[0010] In one example, a fixing tube is provided at the tail end of the weeding knife, and the fixing tube is detachably mounted on the end of the operating rod by means of bolts.

[0011] In one example, the weeding blade is in a curved arc shape that matches the cross-sectional shape of the tobacco field furrow.

[0012] Beneficial effects of the utility model: The utility model is a tobacco field weeding device that is assembled by a walking wheel, a fixed shaft, a connecting rod, an operating rod and a weeding knife. The rapid weeding of the ridge can be achieved by pushing and pulling the operating rod forward with one hand. The operation is relatively simple, and the contact degree between the weeding knife and the soil surface can be adjusted by only controlling the tilt angle of the operating rod. In addition, the blocking rod can not only push away stones in the weeds to avoid damaging the blade, but also can turn over the weeds to improve the weeding effect.

[0014] Description of reference numerals:

[0015] 1 walking wheel, 2 fixed shaft, 3 connecting rod, 4 operating rod, 5 weeding knife, 6 gear lever, 7 fixed cylinder. DETAILED DESCRIPTION

[0016] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0017] See also Figure 1 , this embodiment provides a tobacco field weeding device, including a supporting unit and a weeding unit.

[0018] The support unit includes a running wheel 1, a fixed shaft 2 and a connecting rod 3. The two running wheels 1 can be rotatably mounted on both ends of the fixed shaft 2 for use as a support. The connecting rod 3 is in an upwardly curved arc shape, and one end thereof is fixed to the middle of the running wheel 1. The weeding unit includes an operating rod 4 and a weeding knife 5. The weeding knife 5 is mounted at the bottom end of the operating rod 4. The other end of the connecting rod 3 is connected to the upper part of the lower section of the operating rod 4, and the angle between the operating rod 4 and the connecting rod 3 is an obtuse angle. When in use, the two running wheels 1 are supported at the front end, and the operating rod 4 is tilted downward, and the operating knife can contact the ground, thereby removing weeds during the forward movement.

[0019] Furthermore, a baffle 6 is installed at the bottom of the fixed shaft 2 and between the two running wheels 1. When the running wheel 1 moves forward, the baffle 6 can push the stones forward or sideways to prevent the stones from damaging the blade. At the same time, the baffle 6 can also turn up the weeds to facilitate cutting by the weeding knife 5.

[0020] Furthermore, a fixing tube 7 is connected to the tail end of the weeding blade 5, and the fixing tube 7 is detachably mounted on the end of the operating rod 4 by bolts. Through holes are spaced apart at the tail end of the operating rod 4, so that the fixing tube 7 can be fixed at different positions as needed.

[0021] Furthermore, the weeding blade 5 is in a curved arc shape that matches the cross-sectional shape of the tobacco field furrow, so that the weeds in the furrow can be cleaned up at one time, thereby improving the efficiency.

[0022] The working principle of the above tobacco field weeding device is as follows:

[0023] When in use, the support unit is placed at one end of the furrow, and then the operating rod 4 is held and lifted appropriately so that the blade of the weeding knife 5 is in close contact with the soil surface, and the weeds can be removed by moving forward. Compared with the prior art, the utility model combines the walking wheel 1, the fixed shaft 2, the connecting rod 3, the operating rod 4 and the weeding knife 5 into a tobacco field weeding device, and the rapid weeding of the furrow can be achieved by pushing and pulling the operating rod 4 forward with one hand. The operation is relatively simple, and the contact degree between the weeding knife 5 and the soil surface can be adjusted by only controlling the inclination angle of the operating rod 4. In addition, the blocking rod 6 can not only push away the stones in the weeds to prevent them from damaging the blade, but also can play a role in turning up the weeds to improve the weeding effect.

[0024] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
