Description

Technical Field

[0001] This utility model relates to the field of kudzu planting and processing technology, and in particular to a rhizome-shaped anti-damage digging and harvesting device. Background Technology

[0002] Harvesting root and tuber crops is a crucial step in agricultural production, and the quality of the harvest directly affects the commercial value of agricultural products and the economic benefits for farmers. Currently, most harvesting machinery widely used both domestically and internationally employs a structure of a fixed digging shovel combined with a vibrating separating screen. During operation, the fixed digging shovel penetrates deep below the crop's root layer, scooping up the root and tuber crops along with the soil. Subsequently, a conveying and separating mechanism separates the soil from the fruit.

[0003] However, traditional fixed digging shovel structures have significant drawbacks and limitations in practical applications. In actual agricultural production, the ridge height varies significantly due to factors such as farming habits, soil type, and natural settlement. Because the rigid, fixed digging shovel's entry angle and digging depth are predetermined and unchangeable, it cannot adapt to changing ridge shapes during operation. This often results in digging too deep or too shallow. Digging too deep may upturn the underlying hard soil or stones, mixing them with the fruit and increasing the risk of damage; digging too shallow will leave a large amount of fruit in the soil, causing a decrease in harvest rate and resulting in economic losses. Utility Model Content

[0004] Therefore, it is necessary to address the problem that digging too deep may turn up the underlying hard soil or rocks, mixing them with the fruit and increasing the risk of collision damage; while digging too shallow will result in a large number of fruits being left in the soil, causing a decrease in the harvest rate and economic losses. To address this, a rhizome contour-following anti-damage digging and harvesting device should be provided.

[0005] A rhizome contour-following anti-damage excavation and harvesting device includes: a moving mechanism, which includes an excavator and a conveying assembly;

[0006] The excavating mechanism includes a contouring excavating blade and a feeding plate, wherein the feeding plate is disposed on the side of the contouring excavating blade close to the conveying assembly;

[0007] An adjustment mechanism, comprising a mounting bracket, a preload spring, a connecting plate, and an upper electric push rod;

[0008] The feeding plate is set on the lower surface of the connecting plate via a connecting assembly, the upper electric push rod is set on the lower surface of the mounting bracket, and the preload spring is set between the connecting plate and the upper electric push rod.

[0009] In one embodiment, the conveying assembly has two sets of side plates on the side near the loading plate, the mounting bracket is fixedly disposed above the side plates, and the connecting plate is located above the two sets of side plates.

[0010] In one embodiment, the connecting assembly includes a slider, an extension plate, and an extension column. The extension column is fixedly disposed on the side of the feeding plate away from the contour digging plate. Two sets of sliders and extension plates are provided. The two sets of extension plates are disposed at both ends of the extension column, and the two sets of sliders are disposed on the corresponding side of the extension plate.

[0011] In one embodiment, the two sets of sliders are configured as convex blocks, and the inner sides of the two sets of side plates are provided with grooves corresponding to the sliders.

[0012] In one embodiment, both sets of side plates have through grooves on their sides corresponding to the extension columns, and the through grooves are connected to the corresponding sliding grooves.

[0013] In one embodiment, a limiting cylinder is fixedly provided on the upper surface of the connecting plate, and a pressure plate is slidably provided inside the limiting cylinder, and the pressure plate is disposed between the preload spring and the upper electric push rod.

[0014] In one embodiment, the connecting plate is fixedly connected to two sets of extension plates via a lower extension post, the connecting plate does not contact the two sets of side plates, and the connecting plate is located inside the mounting frame.

[0015] In one embodiment, a lower electric push rod is fixedly disposed on the lower surface of the feed plate, and a guide arc plate is connected to the working end of the lower electric push rod, and a sensor is disposed on the lower side of the guide arc plate.

[0016] Beneficial effects

[0017] 1. The above-mentioned rhizome contour-following anti-damage digging and harvesting device connects the mounting frame and the connecting plate through a pre-compression spring and an upper electric push rod. Then, the connecting plate is connected to the feeding plate through a connecting assembly. The pre-compression spring ensures that the contour-following digging blade is inserted into the soil for digging. The upper electric push rod allows for easy adjustment of the height of the feeding plate, thereby adjusting the height of the contour-following digging blade. When the height of the ridge changes significantly, it is convenient to adjust the digging depth of the contour-following digging blade, thus avoiding digging too deep or too shallow, which would damage the fruit and reduce the harvest rate.

[0018] 2. The above-mentioned rhizome contour-following anti-damage excavation and harvesting device uses a lower electric push rod and a guide arc plate on the lower surface of the feeding plate. The height of the guide arc plate is adjusted by the lower electric push rod, and a sensor connected to the upper electric push rod is set on the lower surface of the guide arc plate. When the height of the ridge increases slightly, the guide arc plate contacts the ridge and drives the feeding plate to increase slightly by the lower electric push rod. When the ridge decreases slightly, the sensor activates the upper electric push rod to drive the feeding plate to decrease slightly by the whole, thus adapting to the ridge shape with small changes in height during operation.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The following is combined with Figures 1-5 This invention describes a rhizome contour-following, damage-preventing digging and harvesting device.

[0028] In one embodiment, a rhizome contour-following anti-damage digging and harvesting device includes: a moving mechanism 100, which includes a digging vehicle 101 and a conveying assembly 102; a digging mechanism 200, which includes a contour-following digging blade 201 and a feeding plate 202, the feeding plate 202 being disposed on the side of the contour-following digging blade 201 near the conveying assembly 102; and an adjusting mechanism 300, which includes a mounting frame 301, a preload spring 303, a connecting plate 305, and an upper electric push rod 311; a lower electric push rod 309 is fixedly disposed on the lower surface of the feeding plate 202, and the working end of the lower electric push rod 309 is connected to a guide arc plate 310, and a sensor is disposed on the lower side of the guide arc plate 310;

[0029] In this embodiment, the conveying assembly 102 includes a chain conveyor belt and a drive motor (model Y100L-2 optional). The moving mechanism 100 drives the digging mechanism 200 and the adjusting mechanism 300 to move as a whole. The kudzu root is dug by inserting the contour digging blade 201 into the soil, and then harvested by passing it through the feeding plate 202 into the conveying assembly 102. The height of the guide arc plate 310 is adjusted by the lower electric push rod 309, thus adjusting the height of the guide arc plate 310 according to the initial height of the ridge. A sensor connected to the upper electric push rod 311 is provided on the lower surface of the guide arc plate 310. When the ridge height increases slightly, the guide arc plate 310 contacts the ridge, and the lower electric push rod 309 drives the feeding plate 202 to rise slightly. When the ridge decreases slightly, the sensor activates the upper electric push rod 311, causing the feeding plate 202 to decrease slightly, thus adapting to small changes in ridge height during operation.

[0030] like Figure 2 , Figure 3 and Figure 5 As shown, the feeding plate 202 is set on the lower surface of the connecting plate 305 via a connecting assembly, the upper electric push rod 311 is set on the lower surface of the mounting frame 301, and the preload spring 303 is set between the connecting plate 305 and the upper electric push rod 311; the conveying assembly 102 is provided with two sets of side plates 302 on the side near the feeding plate 202, the mounting frame 301 is fixedly set on the upper side plate 302, and the connecting plate 305 is located above the two sets of side plates 302; the connecting assembly includes a slider 307, an extension plate 308, and an extension column, the extension column is fixedly set on the side of the feeding plate 202 away from the contour excavator 201, two sets of sliders 307 and extension plates 308 are provided, the two sets of extension plates 308 are set at both ends of the extension column, and the two sets of sliders 307 are set on the corresponding side of the extension plate 308; the two sets of sliders 307 are set as convex blocks, and the inner side of the two sets of side plates 302 is provided with a groove 306 corresponding to the slider 307;

[0031] In this embodiment, the sliders 307 on both sides of the extension column are engaged with the grooves 306 to ensure the stability of the extension column during its up-and-down movement, thereby ensuring the stability of the feeding plate 202 during height adjustment. The mounting frame 301 is connected to the connecting plate 305 by the pre-compression spring 303 and the upper electric push rod 311. The connecting plate 305 and the feeding plate 202 are connected by the extension column, sliders 307 and extension plate 308. The pre-compression spring 303 ensures that the contour digging blade 201 is inserted into the soil for digging. The upper electric push rod 311 facilitates the adjustment of the height of the feeding plate 202, thereby adjusting the height of the contour digging blade 201. When the height of the ridge changes significantly, the upper electric push rod 311 adjusts the digging depth of the contour digging blade 201, thereby avoiding excessive or shallow digging that could damage the fruit and reduce the harvest rate.

[0032] In this embodiment, the preload of the preload spring 303 can counteract the soil resistance when the contour digging blade 201 enters the soil, so that the contour digging blade 201 maintains a stable soil depth and avoids the digging depth from fluctuating due to soil resistance. When the upper electric push rod 311 drives the pressure plate 312 to move downward, the preload spring 303 pushes the connecting plate 305 downward under the pressure of the pressure plate 312, ensuring that the feeding plate 202 and the contour digging blade 201 are lowered synchronously. When the upper electric push rod 311 retracts, the preload spring 303 resets under its own elastic force, driving the connecting plate 305 to move upward, and the auxiliary adjustment mechanism 300 returns to its initial state.

[0033] like Figure 2 , Figure 3 and Figure 5 As shown, both sets of side plates 302 have through slots corresponding to the extension columns on their sides, and the through slots are connected to the corresponding sliding grooves 306; a limiting cylinder 304 is fixedly installed on the upper surface of the connecting plate 305, and a pressure plate 312 is slidably installed inside the limiting cylinder 304, and the pressure plate 312 is located between the preload spring 303 and the upper electric push rod 311; the connecting plate 305 is fixedly connected to the two sets of extension plates 308 through the lower extension column, the connecting plate 305 does not contact the two sets of side plates 302, and the connecting plate 305 is located inside the mounting bracket 301;

[0034] In this embodiment, the through groove and the slide 306 are connected to ensure the stability of the extension column and the loading plate 202 during the lifting process; and a limiting cylinder 304 is set to limit the internal pressure plate 312. When the upper electric push rod 311 drives the pressure plate 312 to move, the stability of the pre-compression spring 303 and the pressure plate 312 during the movement process is ensured. Then, the extension plate 308 drives the extension column to lift and lower, thereby ensuring the stability of the loading plate 202 during the lifting and lowering process.

[0035] Working principle: Before digging kudzu, the initial height of the feeding plate 202 and the contour digging blade 201 is adjusted by the upper electric push rod 311, and the initial height of the guide arc plate 310 is adjusted by the lower electric push rod 309. Then, the moving mechanism 100 drives the digging mechanism 200 and the adjusting mechanism 300 to move synchronously for digging and harvesting. When the ridge height increases slightly, the guide arc plate 310 contacts the ridge, and the lower electric push rod 309 drives the feeding plate 202 to rise slightly. When the ridge height decreases slightly, the sensor activates the upper electric push rod 311 to drive the feeding plate 202 to decrease slightly. When the ridge height changes significantly, the upper electric push rod 311 is set to easily adjust the height of the feeding plate 202, thereby adjusting the height of the contour digging blade 201, and then adjusting the digging depth of the contour digging blade 201, thus avoiding digging too deep or too shallow, which would damage the fruit and reduce the harvest rate.

[0036] It should be noted that the sensors, lower electric actuator 309, and upper electric actuator 311 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the sensors, lower electric actuator 309, and upper electric actuator 311 can be powered by the built-in power supply or by AC power. The specific power supply method should be selected according to the situation, and will not be elaborated here.

[0037] It should be noted that the sensor in this application is a contact displacement sensor, and the model can be an LVDT linear displacement sensor. Its sensing probe is embedded in the arc-shaped groove on the lower surface of the guide arc plate 310, and the probe surface is flush with the lower surface of the guide arc plate 310 to avoid soil impurities from affecting the sensing accuracy. The sensor is electrically connected to the microcontroller of the device, and the model can be an STM32F103. The controller has a built-in delay filtering algorithm, which can filter the instantaneous interference signal generated by the impact of soil particles. When a raise or lower adjustment command is received, the controller drives the upper electric push rod 311 to extend or retract.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
