Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, and specifically discloses an automatic collection traction type Peucedanum praeruptorum Dunn harvester. Background Technique

[0002] Peucedanum praeruptorum Dunn mainly grows in Ningguo City, Anhui Province. Due to the particularity of the geographical environment in Ningguo, the local Peucedanum praeruptorum Dunn is a geographical indication product, so it is called "Peucedanum praeruptorum Dunn". As a Chinese medicinal material with a wide range of medicinal values, Peucedanum praeruptorum Dunn can treat bronchitis, cold cough and other symptoms. Modern research shows that it also has effects such as anti-arrhythmia, anti-heart failure, blood pressure lowering, anti-inflammatory, analgesic, antipyretic, etc.

[0003] Peucedanum praeruptorum Dunn is generally planted in hilly areas, suitable for fertile and deep sandy soil, and the harvesting season is the winter solstice every year. Due to the weather, the soil is mostly frozen soil. Therefore, the harvesting of Peucedanum praeruptorum Dunn is an important link in the harvesting process of Peucedanum praeruptorum Dunn, which has a decisive impact on the yield and quality of Peucedanum praeruptorum Dunn. At present, the harvesting methods are mostly traditional manual harvesting or picking after excavation by harvesting machinery. The soil removal effect is not obvious, resulting in low cleaning rate of Peucedanum praeruptorum Dunn harvesting, low work efficiency, high labor cost, and often unable to complete the task during the harvesting period, and the economic benefits of medicinal farmers decline. Therefore, aiming at the deficiencies of traditional manual harvesting and the existing vibration centrifugal self-propelled Peucedanum praeruptorum Dunn harvester, such as large excavation resistance and unreasonable root-soil separation effect, this application proposes a traction type Peucedanum praeruptorum Dunn harvester with simple structure, small excavation resistance and excellent root-soil separation effect. Content of the Utility Model

[0004] In order to overcome the problems and defects in the prior art, the utility model provides an automatic collection traction type Peucedanum praeruptorum Dunn harvester to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An automatic collection traction type Peucedanum praeruptorum Dunn harvester includes a frame, a digging device, a vibration device, a soil crushing device, a conveying device, a transmission device, and a hydraulic system. The digging device is arranged at the front lower end of the frame, and the vibration device is arranged at the lower end of the frame. The conveying device includes a lifting chain and a transmission shaft. The soil crushing device includes a soil crushing roller arranged on the lifting chain. A transmission device for driving the vibration device, the soil crushing device and the conveying device to operate is arranged on the frame. It also includes a collection device connected to the rear end of the frame. The collection device includes an open mouth that penetrates through the front and rear. A movable rear cover is provided at the rear open mouth. When the rear cover is closed, a receiving space with only a front opening is formed. The front opening faces the conveying device, and the harvested Peucedanum praeruptorum Dunn is stored in the receiving space.

[0007] Preferably, the collecting device includes side plates on the left and right sides, a bottom plate arranged below the two side plates, a rotating rear cover, and a hydraulic rod. The two side plates are in a fan-shaped structure. The upper ends of the rotating rear cover are respectively movably connected to the two side plates. One end of the hydraulic rod is movably connected to the side plate through a pin shaft, and the other end is movably connected to the rotating rear cover through a pin shaft. The rotating rear cover is opened by driving the hydraulic rod to unload materials.

[0008] Preferably, a depth limiting device is provided at the rear end of the frame. The depth limiting device includes a depth limiting wheel, a wheel shaft, and a support rod. The depth limiting wheel is connected to the lower end of the support rod through the wheel shaft, and the upper end of the support rod is fixedly connected to the frame. The setting of the above depth limiting device can ensure the penetration depth of the drag reduction and soil penetration shovel in the front excavation device.

[0009] Preferably, the excavation device includes a drag reduction and soil penetration shovel, a connecting plate, and a soil guiding fence. The drag reduction and soil penetration shovel includes a horizontally arranged horizontal tooth plate and a vertical tooth plate perpendicular to the horizontal tooth plate. The front end of the vertical tooth plate is a sharp structure. The drag reduction and soil penetration shovel is connected to the front end of the connecting plate, and the soil guiding fence is connected to the rear end of the connecting plate. The drag reduction and soil penetration shovel is designed with reference to the shark fin based on the bionic drag reduction principle. When specifically set, the width of the excavation shovel can be set within the range of 0.8 - 1.0 m (the agronomic requirements for planting Peucedanum praeruptorum Dunn are generally ridge cultivation, the plant row spacing is 250 mm, the ridge width is generally about 810 mm, the ditch width is about 200 mm, and the ridge height is about 180 mm). When the penetration depth of the drag reduction and soil penetration shovel reaches about 200 mm, the drag reduction and soil penetration shovel will cut and harvest Peucedanum praeruptorum Dunn. And in order to prevent the harvested Peucedanum praeruptorum Dunn from falling back into the soil again, a soil guiding fence is welded behind the connecting plate to convey the harvested Peucedanum praeruptorum Dunn to the vibration device at the back.

[0010] Preferably, the vibration device includes a crank-rocker mechanism, a baffle plate, a soil cutting plate, and a screen. The crank-rocker mechanism includes an eccentric wheel, a connecting rod, and a rocker. The eccentric wheel is connected to the bearing seat on the frame. One end of the connecting rod is connected to the eccentric wheel, and the other end is connected to the rocker through a shaft. The baffle plate and the soil cutting plate are welded and fixed and then connected to the lower end of the rocker. The screen is composed of screen bars and a connecting plate welded together and is arranged at the lower end of the frame and connected to the lower end of the baffle plate. The above vibration device realizes the movement of the baffle plate and the soil cutting plate through the crank-rocker mechanism to cut the soil blocks. The size of the screen holes in the screen is specially made according to the size of the roots of Peucedanum praeruptorum Dunn to ensure that Peucedanum praeruptorum Dunn will not be left in the soil. The sharp soil cutting plates on both sides cut the soil section under the action of the traction force, facilitating the vibration operation. After the drag reduction and soil penetration shovel digs up the rhizomes of Peucedanum praeruptorum Dunn, under the action of the forward traction force, the root-soil mixture continuously enters the vibrating screen. The crank-rocker mechanism with a speed of 1200 - 1500 r / min drives the vibrating screen to vibrate, and through the vibration of the screen surface, the soil is broken and the roots of Peucedanum praeruptorum Dunn are effectively separated from the soil. When the vibration device operates, it moves forward while vibrating, screening out the broken soil, which can effectively reduce the power consumption.

[0011] Preferably, the soil crushing device includes a soil crushing roller. The roller shafts at both ends of the soil crushing roller are connected to the bearings on the frame, and soil crushing ribs are welded on the surface of the soil crushing roller.

[0012] Preferably, the conveying device includes a lifting chain provided with a conveyor belt shaft. The two ends of the conveyor belt shaft are rotatably connected to the bearing seats on the frame. During the reciprocating vibration of the vibrating screen in the front and rear directions, the root-soil mixture will move on the screen surface, such as sliding upward, sliding downward, and being thrown off, so that the vibration-crushed soil falls to the ground through the screen surface, and the uncompletely separated root-soil mixture is transported to the conveyor belt at the rear to continue the root-soil separation. The conveyor belt is driven by large-tooth sprockets at both ends of the transmission shaft. Due to the special structure of the large-tooth sprockets, the conveyor belt will generate a certain self-excited vibration during the working process, so that the soil with a diameter smaller than the aperture size of the conveyor belt on the belt surface will fall to the ground. Therefore, for the mixture of the root and rhizome of Peucedanum praeruptorum Dunn and soil preliminarily separated by the vibrating screen, the conveyor belt can play a role in separating the fine soil blocks on the rhizome.

[0013] Preferably, the transmission device includes a gearbox, and the gearbox directly or indirectly drives the vibrating device, the soil crushing device, and the conveying device through a transmission belt and a transmission chain.

[0014] The beneficial effects of the present utility model are as follows: The present utility model is provided with a collecting device, which is convenient for collecting Peucedanum praeruptorum Dunn. The collecting device collects the harvested Peucedanum praeruptorum Dunn in the collecting box, eliminating the need for manual picking. When the collecting box is full of Peucedanum praeruptorum Dunn, the hydraulic system works to unload the harvested Peucedanum praeruptorum Dunn, with high harvesting efficiency. In addition, the present utility model adds a lifting chain, installs a soil crushing roller on the lifting chain, and removes the roller for screening by centrifugation at the rear end. The structure of the entire harvester is not only simpler, but also can remove soil from the harvested Peucedanum praeruptorum Dunn again, improving the cleanliness rate of Peucedanum praeruptorum Dunn. Coupled with the modified design of the soil-reducing and soil-penetrating shovel and the screen, the harvesting rate of Peucedanum praeruptorum Dunn by the entire harvester is greatly improved, and its use effect is excellent and the practicability is strong.

[0025] Embodiment

[0026] As shown in the appended Figure 1 and Figure 8 drawings, an automatic collection traction type Peucedanum praeruptorum Dunn harvester includes a frame 3, an excavation device 1, a vibration device 2, a soil crushing device 4, a conveying device 5, a transmission device 6 and a collection device 7.

[0027] As shown in the appended Figure 1 and 2As shown in the figure, the excavation device 1 is arranged at the front lower end of the traction frame 3. Specifically, the excavation device 1 is composed of a drag reduction soil shovel 11, a connecting plate 12, and a soil guiding fence 13. During installation, the drag reduction soil shovel 11, the connecting plate 12, and the soil guiding fence 13 are welded together, and the welded whole is installed at the front lower end of the traction frame 100. The excavation width of the entire excavation device 1 can be set within the range of 0.5 - 1.5 m. During driving, when the depth of the drag reduction soil shovel 11 entering the soil reaches about 200 mm, the drag reduction soil shovel will harvest the Qianhu in front. At the same time, in order to prevent the harvested Qianhu from falling back into the soil again, the soil guiding fence 13 welded to the rear end of the connecting plate 12 can convey the harvested Qianhu to the vibration device 2 at the rear side.

[0028] As shown in the attached Figure 1 and 3 figure, the vibration device 2 is arranged on the traction frame at the rear side of the excavation device 1. Specifically, the crank-rocker mechanism in the vibration device 2 includes an eccentric wheel, and then it is installed on one side of the traction frame. The sieve mesh is composed of sieve bars 21 and a connecting plate 22 welded together, and it is arranged below the traction frame and is connected to the rear end of the excavation device 1 at the same time. During installation, the gap between the sieve bars 21 can be set at about 55 mm according to the size of the Ningqianhu, and the rotational speed of the vibrating screen is controlled within the range of 420 r / min for the first soil screening, while ensuring that the Qianhu will not be left in the soil.

[0029] As shown in the attached Figure 4 figure, the soil crushing device 4 is composed of soil crushing ribs 41 and a soil crushing roller 42. Among them, the soil crushing ribs 42 are welded to the soil crushing roller 42 and fixedly installed on the traction frame. Specifically, the soil crushing device 4 can be arranged at the upper rear end of the elevating chain. During the conveying process, the soil crushing roller 42 can crush the large soil blocks attached to the roots of the Qianhu to achieve a higher soil screening rate.

[0030] As shown in the attached Figure 5 figure, the conveying device 5 is driven by a conveyor belt shaft 52 to drive a conveying gear 53, and the rotation of the gear makes the entire elevating chain move in a cycle. Among them, a sieve mesh 51 is opened on the elevating chain to filter soil blocks, and there are also soil crushing knives 54 to break large soil blocks. During the reciprocating vibration of the vibrating screen in the front and rear directions, the root-soil mixture will perform upward sliding, downward sliding, and throwing-off movements on the sieve mesh 51, so that the vibration-crushed soil passes through the sieve surface and falls to the ground, and the uncompletely separated root-soil mixture is transported to the rear conveying mesh belt for further root-soil separation. The conveying mesh belt is driven by large tooth sprockets at both ends of the transmission shaft. Due to the special structure of the large tooth sprockets, the conveying mesh belt will generate a certain self-excited vibration during operation, so that the soil with a diameter smaller than the mesh aperture size of the mesh belt surface will fall to the ground. Therefore, for the mixture of the Ningqianhu rhizome and soil that has been preliminarily separated by the vibrating screen, the conveying mesh belt can play a role in separating the fine soil blocks on the rhizome.

[0031] As shown in the appendix Figure 6 As shown, the transmission device 6 is composed of a gearbox 614, a front pulley 61, a rear pulley 62, a double-row sprocket one 63, a double-row sprocket two 64, a sprocket one 65, a sprocket two 67, a sprocket three 67, a gear 68, a sprocket four 69, a sprocket five 610, a sprocket six 611, a rocker 612 and an eccentric wheel 613. During the driving process, the gearbox 614 drives the rear pulley 62 to rotate through the front pulley 61. The rear pulley 62 and the double-row sprocket one 63 are connected by a shaft, so as to drive the double-row sprocket one 63 to rotate. The double-row sprocket two 64 and the sprocket one 65 are connected together by a shaft. The sprocket one 65 drives the conveying device 5 to rotate through a chain connecting the sprocket three 67. The sprocket three 67 and the gear 68 are connected by a shaft. The gear 68 and the sprocket four 69 are engaged and rotated together. Thus, the sprocket four 69 drives the soil-breaking device 4 to rotate through a chain connecting the sprocket six 611. The double-sided pulley drives the main shaft to rotate. The main shaft drives the eccentric wheel 613 to rotate through the rocker 612, so that the vibration device 2 can vibrate.

[0032] As shown in the appendix Figure 7 As shown, the collection device 7 includes side plates 72, a bottom plate 74, a rotating rear cover 71 and a hydraulic rod 73. The side plates 72 and the bottom plate 74 are used to catch the Peucedanum praeruptorum transported. The rotating rear cover 71 can rotate for discharging.

[0033] The working principle of the present utility model: When the Peucedanum praeruptorum harvester works, the whole machine is driven by a tractor to move forward. The digging depth and the traveling speed of the harvester are controlled by the tractor. When harvesting Peucedanum praeruptorum, the digging device 1 digs up the soil and the Peucedanum praeruptorum growing in the soil, and it falls onto the vibrating screen 21 as the harvester moves forward. The vibrating screen realizes reciprocating swing through the crank-rocker mechanism in the vibration device 2, and pats the dug-up soil and the Peucedanum praeruptorum root-soil complex, so as to promote the separation of the Peucedanum praeruptorum root-soil complex from the soil, and realize the preliminary root-soil separation through the vibrating screen 21; the root-soil complex after the preliminary root-soil separation is sent to the conveying device 5 by the vibrating screen and is conveyed backward along with the movement of the conveying device 5. The root-soil complex conveyed up is subjected to large-piece separation by the soil-breaking device 4, and the large-piece soil is extruded and broken into small-piece soil. The Peucedanum praeruptorum that has completed the root-soil separation is conveyed backward under the action of the conveying device 5 and finally falls into the collection device 7. During the root-soil separation process, the broken soil falls from the gaps of the vibrating screen 21 and the conveying device 5.
