Description

Technical Field

[0001] This utility model relates to the field of rhizome and medicinal herb excavators, and in particular to a medicinal herb excavator with rhizome and medicinal herb collection function. Background Technology

[0002] With the continuous development of science and technology, most agricultural work has now been replaced by machines, and medicinal herb collection is one of them. From the original manual digging to the current equipment digging, the efficiency of the work has been improved and a lot of manpower has been saved.

[0003] The existing root and rhizome excavators dig out the root and rhizome herbs from the soil and transport them to a collection hopper via a conveyor belt. The disadvantage is that, although the root and rhizome herbs are screened multiple times during the excavation process, a large amount of soil still adheres to their surface and enters the collection hopper. Moreover, the existing collection hoppers are all enclosed, which makes it impossible to further remove the soil from the surface of the root and rhizome herbs. In addition, the collected root and rhizome herbs contain a lot of soil clumps, which require subsequent sorting. Utility Model Content

The primary transfer component transports the soil and rhizomes to a higher position, enabling multi-stage screening using the height difference. The primary screening component separates the loose soil from the rhizome medicinal herbs and clods of soil, allowing the loose soil to fall back into the field, while the rhizome medicinal herbs and clods of soil fall into the secondary screening unit above the collection box. The process involves separating large clods of soil, allowing smaller clods and root herbs to fall into the cleaning section within the collection chamber. Root herbs and medium-sized clods may become stuck between the bristles of the first and second cleaning brush rollers. The cleaning section then uses the first and second cleaning brush rollers, which rotate in two directions, to perform a rolling brushing motion on the root herbs and medium-sized clods. During this process, the soil adhering to the surface of the root herbs is cleaned and falls into the lower third-stage screening section. The medium-sized clods, after being repeatedly rolled and brushed, break up and also fall into the lower third-stage screening section. The third-stage screening section then vibrates to screen out small clods and loose soil, which fall into the field. The root herbs, after being rolled and brushed, vibrate and move towards the discharge port for subsequent bagging. Attached Figure Description

[0052] The soil-shoveling assembly 3000 is located inside the frame 1000 near one end of the frame 1000, wherein the front drive unit 2100 drives the soil-shoveling assembly 3000.

[0053] The soil-shoveling assembly 5000 is installed inside the frame 1000 and is located on one side of the soil-scraping assembly 3000. The angle adjustment unit controls the soil-shoveling assembly 5000.

[0054] The primary transfer component 6000 is installed inside the frame 1000. The primary transfer component 6000 is located on one side of the soil-shoveling component 5000, away from the soil-digging component 3000. The transfer drive unit 2200 drives the primary transfer component 6000.

[0055] The primary screening component 7000 is installed inside the frame 1000, and is located on one side of the primary transfer component 6000 away from the soil-shoveling component 5000.

[0056] The collection component 8000 is installed inside the frame 1000, and the collection component 8000 is located on one side of the primary screening component 7000 away from the primary transfer component 6000. The collection component 8000 includes a collection box 8100, a secondary screening section 8200, a cleaning section and a tertiary screening section 8300. The secondary screening section 8200 is installed on the top of the collection box 8100. A hollow collection cavity 8110 is provided at the center of the collection box 8100. The cleaning section and the tertiary screening section 8300 are arranged from top to bottom inside the collection cavity 8110.

[0057] The cleaning unit includes multiple first cleaning brush rollers 8410, multiple second cleaning brush rollers 8420, a cleaning sprocket 8430, a first cleaning motor 8440, and a second cleaning motor 8450. The outer circumferential surfaces of the first cleaning brush rollers 8410 and second cleaning brush rollers 8420 are all provided with bristles. The multiple first cleaning brush rollers 8410 and second cleaning brush rollers 8420 are arranged alternately and rotatably within the collection cavity 8110. One side of the first cleaning brush roller 8410 penetrates the frame 1000 and is equipped with a cleaning sprocket 8430; the other side of the second cleaning brush roller 8420 penetrates the frame 1000 and is equipped with a cleaning sprocket 8430. The first cleaning motor 8440 and the second cleaning motor 8450 are located at the other end of the frame 1000, and the output end of the first cleaning motor 8440 is equipped with a cleaning sprocket 8430. The output end of the 0 is equipped with a cleaning sprocket 8430. The cleaning sprocket 8430 at the output end of the first cleaning motor 8440 is connected and engaged with the cleaning sprocket 8430 of the first cleaning brush roller 8410 via a chain. The cleaning sprocket 8430 at the output end of the second cleaning motor 8450 is connected and engaged with the cleaning sprocket 8430 of the second cleaning brush roller 8420 via a chain. The rotation direction of the first cleaning motor 8440 is opposite to that of the second cleaning motor 8450. The distance between the first cleaning brush roller 8410 and the second cleaning brush roller 8420 is determined according to the diameter of the root and stem medicinal material to ensure that each root and stem medicinal material can fall into the three-stage screening section 8300 after the roller brushing is completed. At the same time, the bristles on the outer circumferential surface of the first cleaning brush roller 8410 and the second cleaning brush roller 8420 facilitate the brushing of soil clods and medium-sized soil clods on the surface of the root and stem medicinal material.

[0058] In this invention, a user uses a medicinal herb excavator with a rhizome collection function to collect and excavate medicinal herbs from a field. The user needs to use a tractor to tow the excavator. The rear of the tractor drives the front drive unit 2100. At this time, the soil-digging component 3000 at one end of the frame 1000 contacts the soil, and the front drive unit 2100 drives the soil-digging component 3000 to work, making the soil soft. Simultaneously, the tractor pulls the excavator forward, causing the soil-shoveling component 5000 to scoop up the soft soil containing the medicinal herbs and move it to the primary transfer unit 6000. Directional transmission: The user controls the angle adjustment unit according to the planting depth of the rhizome medicinal materials, adjusting the tilt angle of the soil-shoveling component 5000. This allows the soil and rhizome medicinal materials excavated by the soil-shoveling component 3000 to be transported to the primary transfer component 6000. At this time, the transfer drive unit 2200 drives the primary transfer component 6000 to rotate, causing the soil containing the rhizome medicinal materials to be tilted upwards and transported to the primary screening component 7000. The primary screening component 7000 vibrates, performing primary screening on the soil containing the rhizome medicinal materials, removing fine loose soil. The roots and some large clods of soil fall back into the soil, while the roots and some large clods enter the collection component 8000. The secondary screening section 8200 in the collection component 8000 is used to intercept large clods of soil, while the root and stem herbs and medium and small clods of soil enter the collection chamber 8110 through the secondary screening section 8200. The root and stem herbs and medium and small clods of soil fall between the bristles of the first cleaning brush roller 8410 and the second cleaning brush roller 8420. At this time, the first cleaning motor 8440 and the second cleaning motor 8450 work simultaneously, so that the first cleaning brush roller 8410 and the second cleaning brush roller 8420... Simultaneously rotating, the first cleaning brush roller 8410 rotates in the opposite direction to the second cleaning brush roller 8420, thereby further brushing the surface of the root and stem medicinal materials and medium-sized soil clods. After being brushed, the root and stem medicinal materials fall onto the third-level screening section 8300, while the medium and small soil clods are broken after being brushed and also fall onto the third-level screening section 8300. At this time, the third-level screening section 8300 will discharge the root and stem medicinal materials that have completed the brushing through vibration. At the same time, the vibration further shakes off the loose soil attached to the surface of the root and stem medicinal materials, and the broken soil clods are screened out by the third-level screening section 8300 and returned to the field.

[0059] Furthermore, such as Figures 3-7As shown, the secondary screening unit 8200 includes a secondary screening plate 8210, multiple supporting hinge frames 8220, and multiple reciprocating springs 8230. The multiple supporting hinge frames 8220 are arranged on one side of the top of the collection box 8100, and one end of each reciprocating spring 8230 is arranged on the other side of the top of the collection box 8100. One end of the secondary screening plate 8210 has multiple rotating grooves, and one end of each supporting hinge frame 8220 is located within one of these rotating grooves. A rotating shaft passes through the supporting hinge frame 8220 within the rotating groove. The other end of each reciprocating spring 8230 is fixedly located at the bottom of the secondary screening plate 8210. A secondary sieve hole 8211 is provided at the center of the secondary screening plate 8210. Figure 4 As shown, the secondary screening plate 8210 is inclined. When root and stem medicinal materials, large and small soil clods fall from the primary screening component 7000 onto the secondary screening plate 8210, the large and small soil clods will break due to the fall from a height. The secondary sieve holes 8211 are used to screen out root and stem medicinal materials and soil clods smaller than the diameter of the secondary sieve holes 8211. Soil clods larger than the diameter of the secondary sieve holes 8211 will slide into the field as the secondary screening plate 8210 is inclined. The supporting hinge frame 8220 is rotatably connected to the secondary screening plate 8210 to mitigate some of the displacement caused by the impact on the secondary screening plate 8210. The reciprocating spring 8230 is used to buffer the impact force of soil clods and root and stem medicinal materials falling onto the secondary screening plate 8210 and to assist the secondary screening plate 8210 in returning to its original position.

[0060] Furthermore, such as Figure 6 and Figure 7As shown, the three-stage screening unit 8300 includes a three-stage screening plate 8310, multiple shock-absorbing springs 8330, and a vibration motor 8320. A placement platform 8130 is provided near the bottom of the collection chamber 8110. A placement slot 8120 is opened on one side of the collection box 8100, which is connected to the collection chamber 8110. Multiple shock-absorbing springs 8330 are arranged on the placement platform 8130. The other end of the multiple shock-absorbing springs 8330 is fixedly connected to the three-stage screening plate 8310. The other end of the three-stage screening plate 8310 extends out of the placement slot 8120. A vibration motor 8320 is provided at the bottom of one end of the three-stage screening plate 8310. Multiple three-stage sieve holes 8311 are opened on the three-stage screening plate 8310. After being brushed, the root and stem medicinal materials fall onto the three-stage screening plate 8310. At this time, the vibration motor 8320 is in working condition, driving the three-stage screening plate 8310 to vibrate, causing the root and stem medicinal materials brushed on the three-stage screening plate 8310 to move towards the placement slot 8120. Multiple shock-absorbing springs 8330 are arranged at the bottom of the three-stage screening plate 8310 to assist the vibration of the three-stage screening plate 8310 under the vibration motor 8320. The three-stage screening plate 8310 has multiple three-stage sieve holes 8311, the diameter of which is smaller than the diameter of the root and stem medicinal materials to prevent the medicinal materials from falling into the field. The broken small soil clods and loose soil will fall into the field through the three-stage sieve holes 8311.

[0061] Further, as shown in the figure, the soil-shaving assembly 3000 includes a soil-shaving shaft 3100 and a soil-shaving sprocket 3200. Both ends of the soil-shaving shaft 3100 pass through the frame 1000 and are equipped with soil-shaving sprockets 3200. Multiple soil-shaving ribs 3400 are arranged on the outer circumferential side wall of the soil-shaving shaft 3100, and multiple soil-shaving blades 3300 are arranged on the soil-shaving ribs 3400.

[0062] Furthermore, such as Figures 1-4 As shown, the medicinal herb excavator with rhizome collection function also includes a bulldozing component 4000. The bulldozing component 4000 is housed within the frame 1000 and located above the shoveling component 5000. The bulldozing component 4000 includes a bulldozing shaft 4100 and bulldozing sprockets 4200. Both ends of the bulldozing shaft 4100 penetrate the frame 1000 and are equipped with bulldozing sprockets 4200. Multiple bulldozing plates 4300 are arranged on the outer circumference of the bulldozing shaft 4100. The shoveling component 3000 loosens the soil containing the rhizome medicinal herbs. The tractor pulls the excavator forward, causing the shoveling component 5000 to move forward and scoop up the loosened soil containing the rhizome medicinal herbs. During this process, the bulldozing component 4000 ensures that the soil containing the rhizome medicinal herbs enters the primary transfer unit 6000, thus accelerating the overall collection efficiency.

[0063] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, the front drive unit 2100 includes a front universal gearbox 2110, a bearing bracket 2120, and a front drive sprocket 2130. The bearing components are respectively disposed at both ends of the suspension frame 1100, and the universal gearbox 2110 is disposed at the center of the suspension frame 1100. The drive shafts extending from the universal gearbox 2110 pass through the bearing brackets 2120 at both ends and are disposed at the front drive sprocket 2130. The front drive sprocket 2130 is connected to the soil-digging sprocket 3200 and the bulldozing sprocket 4200 respectively via chains.

[0064] like Figure 3 As shown, the tractor in front will drive the universal gearbox 2110, which will output transmission power to the drive shaft to realize the change of power direction, thereby driving the front drive sprocket 2130 to rotate. The front drive sprocket 2130 is linked with the soil-shoveling sprocket 3200 and the bulldozing sprocket 4200 through a chain, thereby driving the soil-shoveling shaft 3100 to rotate. This causes the soil-shoveling rib plate 3400 and the soil-shoveling blade 3300 on the soil-shoveling shaft 3100 to rotate synchronously, thereby realizing the digging and soil-shoveling function. At the same time, the bulldozing shaft 4100 also rotates with the soil-shoveling shaft 3100, causing the bulldozing plate 4300 on the bulldozing shaft 4100 to push the soil and root medicinal materials on the shovel assembly.

[0065] Furthermore, such as Figure 3 As shown, the soil-shoveling assembly 5000 includes a soil-shoveling plate 5100, which is rotatably mounted within the frame 1000. Multiple shovel teeth 5110 are provided at one end of the soil-shoveling plate 5100. The shovel teeth 5110 facilitate the movement of the soil-shoveling plate on the ground, assisting in shoveling out soil.

[0066] Furthermore, such as Figure 4 As shown, the angle adjustment unit includes multiple push cylinders 2310, which are arranged at an angle on the angle support frame 1300. The other end of the shovel plate 5100 has a bottom hinge block, and the output end of the push cylinder 2310 is provided with a mating block. The hinge block and the mating block are rotatably mated, and the number of hinge blocks is the same as the number of push cylinders 2310.

[0067] The angle adjustment principle of the shovel plate assembly is as follows: By controlling multiple push cylinders 2310 to push the other end of the shovel plate 5100, the shovel plate 5100 rotates within the frame 1000. When the push cylinder 2310 pushes the other end of the shovel plate 5100, one end of the shovel plate 5100 rotates counterclockwise, thus shoveling deeper soil. When the push cylinder 2310 retracts the other end of the shovel plate 5100, one end of the shovel plate 5100 rotates clockwise. At this time, the shovel plate 5100 can only shovel shallower soil. The output end of the push cylinder 2310 is rotatably connected to the hinge block at the bottom of the other end of the shovel plate 5100, which facilitates the push cylinder 2310 to push the shovel plate 5100.

[0068] Furthermore, such as Figure 3 and Figure 4 As shown, the primary transfer component 6000 includes a transfer belt 6100, a transfer sprocket 6200, a transfer drive shaft 6300, and a transfer driven shaft 6400. Both the transfer drive shaft 6300 and the transfer driven shaft 6400 are rotatably mounted within the frame 1000. One end of the transfer drive shaft 6300 and one end of the transfer driven shaft 6400 both penetrate the frame 1000 and are fitted with the transfer sprocket 6200. The transfer belt 6100 is sleeved on the transfer drive shaft 6300 and the transfer driven shaft 6400. Multiple guardrails 6110 are arranged on the conveyor belt 6100. The conveyor drive unit 2200 includes a rotation drive motor 2210, which is mounted on the rotating placement frame 1200. A conveyor sprocket 6200 is mounted on the output end of the rotation drive motor 2210. The conveyor sprocket 6200 at the output end of the rotation drive motor 2210 is connected to the conveyor sprockets 6200 of the conveyor drive shaft 6300 and the conveyor sprockets 6200 of the conveyor driven shaft 6400 respectively via chains. The primary conveyor 6000 is used to convey soil containing root and stem medicinal materials scooped up by the shovel plate 5100, so that the soil containing root and stem medicinal materials is conveyed to a relatively high place. The soil and root and stem medicinal materials are then transported by gravity as they fall from the height, awaiting the subsequent screening process. The multiple guardrails 6110 on the conveyor belt 6100 are used to convey the soil containing root and stem medicinal materials, reducing the risk of falling during the conveyor process.

[0069] Furthermore, such as Figure 2 , Figure 3 and Figure 4As shown, the primary screening assembly 7000 includes a primary screening plate 7100, screening cams 7220, a group of screening cams 7220 7200, and a screening drive motor 7300. One end of the primary screening plate 7100 is rotatably mounted inside the frame 1000, and the other end of the primary screening plate 7100 is close to the primary transfer component 6000. The primary screening plate 7100 is provided with multiple primary screening holes 7110. The screening cams 7220 and the group of screening cams 7220 include a screening shaft 7210 and multiple screening cams 7220. Both ends of the screening shaft 7210 pass through the frame 1000, and the screening shaft 7210 is located at the center below the primary screening plate 7100. The multiple screening cams 7220 are arranged on the screening shaft 7210. The screening cams 7220 drive the primary screening plate 7100. The screening drive motor 7300 is mounted on the outer wall of the frame 1000, and the output end of the screening drive motor 7300 is connected to one end of the screening shaft 7210. When the primary screening component 7000 is working, the screening drive motor 7300 drives the screening shaft 7210 to rotate, and the screening cam 7220 on the screening shaft 7210 rotates synchronously, causing the screening cam 7220 to deflect. The screening cam 7220 contacts the bottom of the primary screening plate 7100, thereby causing the other end of the primary screening plate 7100 to oscillate up and down. One end of the primary screening plate 7100 rotates within the frame 1000 via a rotating shaft, assisting the oscillation motion of the primary screening plate 7100. The soil and root medicinal materials on the primary screening plate 7100 are oscillated and screened, so that most of the soil, root medicinal materials, and soil clods are separated. The root medicinal materials and soil clods fall into the collection component 8000 under the oscillation of the primary screening plate 7100, waiting for subsequent screening operations.

[0070] Preferably, such as Figure 1 As shown, movable components 9100 are symmetrically arranged at the center of the outer wall of the frame 1000. Most of the movable components 9100 are manually adjustable in height to suit different operating environments.
