Description

Technical Field

[0001] The utility model relates to the technical field of Chinese medicinal material shovels, in particular to a salvia miltiorrhiza harvester which can prevent ground film winding. Background Art

[0002] Salvia miltiorrhiza is a perennial herb, 30 to 80 cm high. The dried roots and rhizomes can be used as medicine. The rhizomes are short and thick, and sometimes the stem base remains at the top. There are several roots, which are long cylindrical, slightly curved, and some are branched with whisker-like fine roots, 10 to 20 cm long and 0.3 to 1 cm in diameter. Since the roots of Salvia miltiorrhiza are brittle and easy to break, they should be dug on sunny days when the soil is semi-dry and semi-wet. After digging, they can be exposed to the sun in the field, the soil can be removed, and they can be transported back for processing to complete the harvest. The existing technology generally uses manual harvesting. If a general-purpose harvester is used, it will cause great damage to Salvia miltiorrhiza; and the general-purpose Chinese medicine harvesting device is easily entangled with the moving parts by debris such as plastic film and weeds in the field during the harvesting process, which makes the machine unable to work or even damaged.

[0003] The Chinese utility model patent with application number 202321777833X discloses a salvia miltiorrhiza harvester, which is provided with cutting discs on the two side walls inside the frame near one end of the knife holder. When the salvia miltiorrhiza harvester moves forward and performs digging and harvesting operations, if there is unremoved ground film on the surface of the field, it will be cut off by the cutting discs on both sides after entering the frame to prevent it from being involved in the moving structure. However, in actual use, it has the following shortcomings: 1. The ground film entering the frame is only cut once. Due to the complexity of the conditions at the harvesting site, it is impossible to cut off all the ground film, and part of the ground film will still enter the subsequent moving structure; 2. The movement of the cutting disc depends on the friction or thrust with the ground film or other debris. It has no power source, so it is easy to get stuck and fail. Utility Model Content

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described below in conjunction with the accompanying drawings. In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0024] Example 1

[0025] like Figure 1 As shown, the salvia miltiorrhiza harvester for preventing ground film entanglement includes a frame 1, a gearbox 2 and a ground wheel 3. A tool holder 4 is arranged at the front end of the frame 1, and also includes: a first cutting disc 5 symmetrically rotatably arranged inside the frame 1 and close to the two side walls of one end of the tool holder 4; a second cutting disc 6 symmetrically rotatably arranged inside the frame 1 and away from the two side walls of one end of the tool holder 4; the outer edges of the first cutting disc 5 and the second cutting disc 6 are both provided with cutting edges.

[0026] When the salvia miltiorrhiza harvester moves forward and performs digging and harvesting operations, if there is unremoved ground film on the surface of the field, it will be cut for the first time by the first cutting discs 5 on both sides after entering the frame 1. If the first cutting disc 5 fails to cut the ground film at this time, it will continue to move to the rear end of the frame 1, and it will be cut for the second time by the second cutting discs 6 on both sides to avoid being involved in the moving structure. Similarly, other debris such as weeds and branches, if they move along the channel inside the frame 11, due to the existence of the conveying mechanism and the screening mechanism, they will not affect other parts of the device. If they move along the edge of the inner wall of the frame 1, they will be cut into small sections by the first cutting disc 5 and the second cutting disc 6 to avoid entanglement and damage to the moving parts of the subsequent device.

[0027] In some preferred embodiments, in order to improve the cutting efficiency of the first cutting disc 5 and the second cutting disc 6, it is considered to set the first cutting disc 5 and the second cutting disc 6 as metal circular saw blades. The metal circular saw blades are mature accessories commonly used in the prior art. This can improve the cutting efficiency of the cutting discs on the one hand, and more conveniently replace worn cutting discs on the other hand.

[0028] Example 2

[0029] like Figure 2As shown, considering providing cutting power for the first cutting disc 5 and the second cutting disc 6 to avoid the disadvantage of relying on the friction or thrust between the cutting disc and the ground film or other debris, the anti-ground film winding Salvia miltiorrhiza harvester provided in this embodiment also includes:

[0030] A first drive motor 7 is arranged outside the side wall of the frame 1 and the output end thereof penetrates through the side wall of the frame 1 and is connected to the first cutting disc 5; a second drive motor 8 is arranged outside the side wall of the frame 1 and the output end thereof penetrates through the side wall of the frame 1 and is connected to the second cutting disc 6. The first drive motor 7 and the second drive motor 8 in this embodiment can adopt the drive motor specifications and models commonly used in the art, and the installation method of the first drive motor 7 and the second drive motor 8 can be determined by those skilled in the art according to their specific specifications and models, for example, a conventional installation method such as an installation platform for installing and fixing the drive motor can be added to the outside of the frame 1, and the present utility model does not make further restrictions on this.

[0031] Furthermore, in order to provide a stable power source for the first drive motor 7 and the second drive motor 8 and to further control the motor's opening and closing, forward and reverse rotation and other working conditions according to the needs of technicians, the anti-film winding salvia harvester includes: a power supply 9 and a control device 10 respectively arranged on the upper surface of the frame 1 near the gearbox 2; the control device 10 is electrically connected to the first drive motor 7 and the second drive motor 8 respectively. It should be noted that Figure 2 Although the connection relationship between the power source 9 and the control device 10 and the first drive motor 7 and the second drive motor 8 on the other side is not indicated, this is because the drive motor on the other side will be completely blocked when drawing and therefore cannot be indicated, and it should not be understood that there is no drive motor on the opposite side or the drive motor is not electrically connected to the power source 9 and the control device 10. Further, the power source 9 is preferably a battery commonly used in the art, and the control device 10 can be an adaptive controller selected by a person skilled in the art in the art in the prior art, and the present utility model does not make further limitations on this.

[0032] In some preferred embodiments, since the internal space of the frame 1 gradually decreases from the front end (digging end) to the rear end (harvest and transport end), in order to make the first cutting disc 5 and the second cutting disc 6 better match the change in the space size to ensure good cutting performance, it is considered to set the diameter of the first cutting disc 5 to be larger than the second cutting disc 6. It should be understood that the specific diameters of the first cutting disc 5 and the second cutting disc 6 can be set by those skilled in the art according to the size of the adapted frame 1 and the actual needs of the site, and the present utility model does not make further limitations.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
