Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery processing, in particular to a full-automatic Prunella vulgaris stem and spike cutting device. Background Technique

[0002] Prunella vulgaris, scientific name: Prunella vulgaris, alias: spike Prunella vulgaris, wire Prunella vulgaris, wheat Prunella vulgaris, wire Prunella vulgaris, Xi Ju, Nai Dong, etc., is a perennial herbaceous plant with creeping rhizomes and fibrous roots growing at the nodes. The stem is up to 300 mm tall, branched at the base, and light purple. Prunella vulgaris has strong adaptability and few diseases and pests during the whole growth process. It has the effect of clearing heat and improving eyesight, and can treat red and swollen eyes, headache, etc., and is a commonly used traditional Chinese medicine.

[0003] Prunella vulgaris and Prunella vulgaris spike are often misunderstood as the same medicinal material, but they are actually different and have different medicinal effects. Prunella vulgaris spike is the spike of Prunella vulgaris, and its medicinal part is completely different from that of Prunella vulgaris. Although their medicinal effects are partially the same, they need to be used according to the prescription when used for treatment.

[0004] The Prunella vulgaris spike is in the shape of a short rod, generally 30-60 mm long and 10-15 mm in diameter, light brown. The whole spike is composed of several to more than 10 rounds of persistent calyces and bracts, overlapping with each other to form a pagoda shape. There are 2 opposite bracts in each round, fan-shaped, with a tail tip at the top, light yellow, obvious vein patterns, and white hairs on the outside; there are 3 flowers in each bract, the corolla has mostly fallen off, the persistent calyx is bilabiate, there are 4 small nuts inside, the small nuts are oval, brown, shiny, with a white protrusion at the tip, light in weight, slightly fragrant, tasteless, the spike is long, red-brown, and the one without a stem is the best.

[0005] In recent years, with the continuous increase in market demand, after Prunella vulgaris is harvested, it is dried and the spikes and stems are used as medicine. Since the spikes are harvested by a harvester, they all have long handles, and generally, scissors are used manually to cut them off. For the work of removing the handles of a large quantity of Prunella vulgaris, manual removal of the handles and stems is time-consuming and laborious, wasting the enterprise's costs and seriously restricting the rapid development of the enterprise.

[0006] The authorized announcement number: CN204191540U disclosed a full-automatic Prunella vulgaris stalk removing machine on March 11, 2015, which includes drums arranged horizontally in the frame in an up-and-down manner and grouped in at least two. A number of stalk removing holes with equal apertures are evenly distributed on the surface of the drums. A number of baffles vertically distributed are horizontally arranged on the inner wall of the drums. Blades are provided on the outer wall of the drums. Feed inlets and discharge outlets are respectively arranged at the head and tail of the drums. The drums are successively the first drum and the second drum from top to bottom. The discharge outlet of the first drum corresponds to the feed inlet of the second drum. A driving device for driving the drums to rotate is provided on the frame. An air guiding device is provided at the corresponding position between the discharge outlet of the first drum and the feed inlet of the second drum. And it is disclosed that the diameter of the stalk removing holes is 8 mm to 10 mm. Since the stem of Prunella vulgaris is as high as 30 cm, when the Prunella vulgaris with a high stem tumbles in the drum, the stem of Prunella vulgaris is not easily inserted into the smaller circular stalk removing holes of the drum, reducing the speed of removing the stalks of Prunella vulgaris. Summary of the Invention

Blades closely attached to the outer wall of the drums are arranged on the first and second drum screens. The blades are arranged at the bottom of the first and second drum screens. The direction of the blades is opposite to the rotation direction of the first and second drum screens. A device for making the blades closely attached to the outer wall of the drum screen is arranged on the frame. The feed inlets of the first and second drum screens are inclined with the feed inlets higher than the discharge outlets. Power devices are arranged at the ends of the first and second drum screens. A blower is arranged on the frame. The air outlet pipe of the blower faces the second feed hopper.

[0010] Preferably, the rotary support device of the drum screen includes a support lifting lug fixedly connected to the frame. A support roller shaft is arranged on the support lifting lug, and a support roller is rotatably connected to the support roller shaft. The outer circle of the support roller is in rolling support connection with the outer circle of the first drum screen or the second drum screen or the like. The side of the support roller is in rolling abutment with the outer side of the retaining ring of the first drum screen or the second drum screen or the third drum screen.

[0011] Preferably, the device for the blade to closely adhere to the outer wall of the drum screen includes a vertical plate fixedly connected to the vertical connecting rod. A triangular plate is fixedly connected to the vertical plate in a vertically adjustable manner. A blade support plate is rotatably connected to the triangular plate. A blade is fixedly connected to the upper surface of the blade support plate in a vertically adjustable manner. A pull rod is fixedly connected to the lower surface of the blade support plate. The end of the pull rod is hooked with a tension spring, and the other end of the tension spring is hooked with a longitudinal connecting rod.

[0012] Preferably, the power device includes a motor fixedly connected to the horizontal connecting rod and a transmission shaft rotatably connected through a transmission shaft support seat.

[0017] Preferably, the diameters of the first and second drum screens are 700 mm to 1000 mm.

[0018] The utility model has the following advantages:

[0019] 1. The optimal shape of the sieve holes of the first and second drum screens of this fully automatic Prunella vulgaris L. stem and spike cutting device is a groove-shaped hole. The optimal size of the groove-shaped hole is a width of 5.5 - 6.0 mm and a length of 15 - 25 mm. The length direction is set along the circumferential direction of the drum screen. When the Prunella vulgaris L. tumbles in the drum screen, the stem of the Prunella vulgaris L. can easily insert into the groove-shaped holes of the drum screen with the length direction set along the circumferential direction of the drum screen, improving the cutting speed of the Prunella vulgaris L. stem and spike. The motor drives the first and second drum screens to rotate through a reduction gearbox, a power output shaft, a transmission shaft, a transmission shaft gear, and a drum screen gear ring. The rotation of the Prunella vulgaris L. in the drum screen drives the Prunella vulgaris L. to move in the barrel through the frictional force of the inner wall of the drum screen on the Prunella vulgaris L. The movement speed of the Prunella vulgaris L. is higher than the sliding speed of the Prunella vulgaris L. at the bottom and lower than the centrifugal movement speed of the Prunella vulgaris L., causing the Prunella vulgaris L. to tumble in the barrel. During the tumbling process, there is a certain probability that the stem of the Prunella vulgaris L. will insert and be clamped into the sieve holes of the first and second drum screens, completing the direction fixation. While the Prunella vulgaris L. is moving, the stem of the Prunella vulgaris L. extends out of the barrel due to centrifugal force. There are blades closely attached to the drum screen outside the drum screen. The rotation of the drum screen generates a shearing force to cut off the stem of the Prunella vulgaris L., and the spike of the Prunella vulgaris L. remains in the drum screen, achieving two-stage cutting of the Prunella vulgaris L. stem and spike and improving the cutting clean rate of the Prunella vulgaris L. stem and spike.

[0020] 3. The outer circle of the support roller of the drum screen rotation support device of this fully automatic Prunella vulgaris L. stem and spike cutting device is in rolling support connection with the outer circle of the drum screen. The structural design of the side of the support roller rolling against the outer side of the drum screen retaining ring prevents the axial movement and radial jump of the drum screen during rotation, improving the stability of the whole machine.

[0021] 4. The push plate set on the drum screen of this fully automatic Prunella vulgaris L. stem and spike cutting device, while pushing the Prunella vulgaris L. to flip, also pushes the Prunella vulgaris L. from the inlet end of the drum screen to the outlet of the drum screen.

[0022] 5. For this fully automatic Prunella vulgaris L. stem and spike cutting device, according to the overall length of the Prunella vulgaris L., the diameters of the first and second drum screens are 700 mm - 1000 mm. If it is too large or too small, the working efficiency of the Prunella vulgaris L. is not high and it will not flip.

[0023] 6. The first stem retaining slide plate that is inclined front and back on the frame between the first drum screen and the second drum screen of this fully automatic Prunella vulgaris L. stem and spike cutting device, while preventing the stem of the Prunella vulgaris L. from falling into the lower drum screen, slides the stem of the Prunella vulgaris L. to one side of the frame for convenient centralized collection.

[0024] 7. The feed ports of the first drum screen and the second drum screen of this fully automatic Prunella vulgaris L. stem and spike cutting device are inclined with the feed port higher than the discharge port. While the Prunella vulgaris L. rotates and tumbles with the drum screen, it will also be convenient to move along the length direction of the drum screen towards the end with the discharge port.

[0025] 8. The air from the air outlet pipe of the fan of the fully automatic Prunella vulgaris L. stem and spike slicing device blows the Prunella vulgaris L. from the second feed hopper into the second drum sieve, preventing blockage during the feeding of Prunella vulgaris L.

[0040] The working principle of this embodiment:

[0041] Prunella vulgaris is fed into the second feed hopper 9 through a feeding device. The air from the air outlet pipe 13.1 of the blower 13 blows the Prunella vulgaris from the second feed hopper 9 into the second drum sieve 4. The stem of Prunella vulgaris is up to 300 mm high, and the spike of Prunella vulgaris is in the shape of a short rod, generally 30 - 60 mm long and 10 - 15 mm in diameter. When the Prunella vulgaris tumbles in the drum sieve, the stem of Prunella vulgaris is not easily inserted into the smaller round sieve holes of the drum sieve. Through repeated experiments, the best shape of the sieve holes 4.2 of the second drum sieve is a groove-shaped hole. The best size of the groove-shaped hole is 5.5 - 6.0 mm in width and 15 - 25 mm in length, and the length direction is arranged along the circumferential direction of the drum sieve. The motor 3.1 drives the second drum sieve 4 to rotate through the reduction box 3.2, the power output shaft 3.3, the transmission shaft 3.4, the transmission shaft gear 3.6 and the drum sieve gear ring 3.7. The rotation of the Prunella vulgaris in the drum sieve drives the Prunella vulgaris to move in the barrel through the friction force of the inner wall of the drum sieve on the Prunella vulgaris. The movement speed of the Prunella vulgaris is higher than the sliding speed of the Prunella vulgaris at the bottom and lower than the centrifugal movement speed of the Prunella vulgaris, so that the Prunella vulgaris tumbles in the barrel. During the tumbling process, there is a certain probability that the stem of the Prunella vulgaris is inserted and clamped into the sieve holes 4.2 of the second drum sieve to complete the fixation of the direction. While the Prunella vulgaris is moving, the stem of the Prunella vulgaris extends out of the barrel due to the centrifugal force. There are blades closely attached to the drum sieve outside the drum sieve. The rotation of the drum sieve generates a shearing force to cut off the stem of the Prunella vulgaris, and the spike of the Prunella vulgaris remains in the drum sieve to achieve the first-stage cutting of the stem and spike of the Prunella vulgaris;

[0042] Prunella vulgaris in the second drum sieve 4 tumbles and slides from the inlet end to the discharge opening 4.1 of the second drum sieve during the rotation of the drum sieve, and falls into the first drum sieve 7 through the first feed hopper 5. The stem of Prunella vulgaris is up to 300 mm high, and the spike of Prunella vulgaris is in the shape of a short rod, generally 30 - 60 mm long and 10 - 15 mm in diameter. When Prunella vulgaris tumbles in the drum sieve, the stem of Prunella vulgaris is not easily inserted into the smaller round sieve holes of the drum sieve. Through repeated experiments, the optimal shape of the sieve holes 7.2 of the first drum sieve is a groove-shaped hole, and the optimal size of the groove-shaped hole is 5.5 - 6.0 mm in width and 15 - 25 mm in length, and the length direction is set along the circumferential direction of the drum sieve; the motor 3.1 drives the second drum sieve 4 to rotate through the speed reducer 3.2, the power output shaft 3.3, the transmission shaft 3.4, the transmission shaft gear 3.6 and the drum sieve gear ring 3.7. The rotation of Prunella vulgaris in the drum sieve drives Prunella vulgaris to move in the barrel through the frictional force of the inner wall of the drum sieve on Prunella vulgaris. The movement speed of Prunella vulgaris is higher than the sliding speed of Prunella vulgaris at the bottom and lower than the centrifugal movement speed of Prunella vulgaris, so that Prunella vulgaris tumbles in the barrel. During the tumbling process, there is a certain probability that the stem of Prunella vulgaris is inserted and clamped into the sieve holes 7.2 of the first drum sieve to complete the fixation of the direction. While Prunella vulgaris is moving, the stem of Prunella vulgaris extends out of the barrel due to the centrifugal force. There are blades closely attached to the drum sieve outside the drum sieve, and the rotation of the drum sieve generates a shearing force to cut off the stem of Prunella vulgaris, and the spike of Prunella vulgaris remains in the drum sieve; during the rotation of the drum sieve, the spike of Prunella vulgaris in the first drum sieve 7 tumbles and slides from the inlet end to the discharge opening 7.1 of the first drum sieve and enters the Prunella vulgaris spike receiving frame 10, realizing the second-stage cutting of the stem and spike of Prunella vulgaris.
