[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] Embodiment 1

[0021] An adjustable salvia miltiorrhiza harvesting and collecting device, referring to Figure 1 , Figure 2 , comprising a rack 1, the rack 1 is provided with a harvesting blade 2, a conveying mechanism 3 and a collecting box 4, the harvesting blade 2 is located at the feeding end of the conveying mechanism 3, the collecting box 4 is communicated with the discharging end of the conveying mechanism 3, the collecting box 4 is provided with an opening at the side wall behind the device in the direction of travel, the opening side wall of the collecting box 4 is provided with a rear baffle 5, the lower side of the rear baffle 5 is connected with the bottom wall of the collecting box 4 through a hinge, the rack 1 is provided with a hydraulic push rod 6, one end of the hydraulic push rod 6 is connected with the rack 1 through a hinge, the other end is connected with the rear baffle 5 through a hinge; when the hydraulic push rod 6 is shortened, the rear baffle 5 blocks the rear opening of the collecting box 4, when the hydraulic push rod 6 is lengthened, the rear baffle 5 rotates backward and opens the rear opening of the collecting box 4; further comprising a controller, the collecting box 4 is provided with a material level sensor 7 inside, the material level sensor 7 and the hydraulic push rod 6 are electrically connected with the controller. The tractor hydraulic connection port is connected with one end of the hydraulic controller through a hydraulic pipe, the other end of the hydraulic controller is connected to a hydraulic valve through a hydraulic pipe, and the hydraulic push rod 6 is controlled to extend and retract through the hydraulic valve.

[0022] One end of the hydraulic push rod 6 is connected to one side of the frame 1 along the device travel direction, and the other end is connected to the corresponding side of the backstop 5 along the device travel direction, that is, the hydraulic push rod 6 is located on one side of the collection box 4, reducing the influence of the hydraulic push rod 6 on the entry of the Danshen into the collection box 4.

[0023] The conveying mechanism 3 belongs to the prior art, such as the Danshen intelligent harvesting machine disclosed in Chinese patent document CN116965222A. The conveying mechanism 3 in the prior art has a grid conveying surface structure. In this embodiment, the conveying mechanism 3 in the prior art can be used, and the specific structure of the conveying mechanism 3 will not be described again in this embodiment. The level sensor 7 is a distance measuring sensor. The distance measuring sensor is arranged on an inner side wall of the collection box 4, and the probe of the distance measuring sensor faces the other inner side wall opposite to it. The distance measuring sensor can use ultrasonic, radar or infrared sensing principles. When the Danshen level rises and blocks the distance measuring sensor, the detection signal will be reflected when encountering the material, which will cause a change in the transmission time of the detection signal, thereby triggering the control signal of the controller.

[0024] In this scheme, when using the Danshen harvesting and collecting device to harvest Danshen, the Danshen harvesting and collecting device is usually pulled by a tractor. The Danshen is conveyed to the collection box 4 by the conveying mechanism 3 for temporary storage. The travel speed of the tractor and the conveying speed of the Danshen by the conveying mechanism 3 are usually fixed, which causes the Danshen to easily fall into a local position in the collection box 4, resulting in a higher Danshen stacking height in the local position in the collection box 4. By arranging the level sensor 7 in the collection box 4, the level sensor 7 monitors the level of the position in the collection box 4 where the Danshen is more likely to be stacked in real time. When the level sensor 7 detects that the local level in the collection box 4 reaches a pre-set value, a signal is sent to the controller. The controller controls the hydraulic push rod 6 to extend, so that the backstop 5 is opened, thereby enabling a part of the Danshen stored in the collection box 4 to be quickly discharged through the rear opening. The Danshen discharged onto the ground is relatively concentrated, which facilitates subsequent centralized picking of the Danshen on the ground. This scheme to some extent reduces the situation that the Danshen is continuously spilled along with the Danshen harvesting and collecting device.

[0025] Further, the collection box 4 is provided with level sensors 7 near the front and rear of the device travel direction. When the travel speed of the tractor or other vehicle equipment used in cooperation with the Danshen harvesting and collecting device is different, the position of the Danshen falling into the collection box 4 will be different. The faster the Danshen harvesting and collecting device travels, the more likely the Danshen is to fall into the rear part of the collection box 4. This scheme facilitates the Danshen harvesting and collecting device to adapt to different travel speeds of the towing equipment by arranging level sensors 7 in front of and behind the collection box 4.

[0026] Embodiment 2

[0027] On the basis of Embodiment 1, with reference to Figure 1 , Figure 2 , the inner bottom wall of the collecting box 4 is inclined, and the end of the inner bottom wall of the collecting box 4 towards the back baffle 5 is the lowest end of the inclination. When the back baffle 5 is opened, part of the salvia miltiorrhiza in the collecting box 4 will be quickly discharged, and due to the inclined arrangement of the inner bottom wall of the collecting box 4, more salvia miltiorrhiza can be discharged to the ground.

[0028] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing embodiments of the present application have been described in detail, for the skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement for the technical solutions recorded in the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
