Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a bat-wing scraper for a ridger. Background Art

[0002] In the ridging work of flue-cured tobacco production, the ridges made by the furrowing accessories equipped with the existing rotary tillage ridging machines are not full and cannot be formed in one go, resulting in 2-3 manual operations per acre to make the ridges full to meet production requirements, resulting in high labor costs.

[0003] After research, the technicians found that the cause of the above problems is that the existing ditching accessories are triangular, including two symmetrical iron plates, the front edges of the iron plates are fixedly connected together to make the front pointed and the rear open, the distance between the two iron plates at the bottom of the iron plate is smaller than the distance between the upper iron plates, and when ditching, the sharp corners of the front of the ditching accessories face forward and are consistent with the direction of movement. The sharp corners of the front of the ditching accessories separate the soil to both sides, and the two sides of the ditching accessories squeeze the soil to the ridges on both sides, so that the soil in the ditch is squeezed onto the ridges. However, since the ditching accessories only squeeze the soil from the ditch body to the ridge body, and do not directly scrape the ridge body, the ridge body cannot be shaped by the ditching accessories, making the ridge body opened by the ditching accessories not full. Summary of the invention

[0004] In order to solve the above shortcomings and deficiencies of the prior art, the object of the present invention is to provide a bat-wing scraper for a ridger.

[0005] The technical solution of the present invention is: a bat-wing scraper for a ridging machine, comprising:

[0006] A T-shaped connector, the T-shaped connector comprising a connecting rod and a mounting rod, one end of the mounting rod is fixedly connected to the middle of the connecting rod, and a mounting hole is provided on the mounting rod;

[0007] The scraper comprises two scrapers, which are symmetrically connected to the connecting rod. The scraper is perpendicular to the mounting rod. A scraping hole is opened on the side of the lower part of the scraper away from the T-connector. The scraping hole is arc-shaped, and the center of the scraping hole is below the lower edge of the scraper;

[0008] A mud pressing plate is fixedly connected to the edge of the scraping hole on the scraper, and the mud pressing plate is distributed along the length direction of the scraping hole. The mud pressing plate is located on the back of the scraper, and the back of the scraper is the side opposite to the movement direction of the scraper when working.

[0009] Furthermore, the radius of the mud pressing plate gradually decreases as it moves away from the scraper.

[0010] Furthermore, the scraper is fixedly connected to a sleeve whose inner cavity is a regular polygon, the connecting rod is a regular polygonal rod matching the inner cavity of the sleeve, the connecting rod is inserted into the sleeve, a screw hole is opened on the side wall of the sleeve, a fixing bolt is threaded on the screw hole, and the fixing bolt is tightened or loosened to fix or loosen the relative position of the connecting rod and the sleeve.

[0011] Furthermore, it also includes:

[0012] The reinforcing ribs are angle steels, which are fixedly connected to the scraper. The reinforcing ribs are located on the back of the scraper. The back of the scraper is the side opposite to the movement direction of the scraper when it is working, and the reinforcing ribs are vertical in the opposite direction.

[0013] The rib plate is fixedly connected between the mud pressing plate and the scraper plate.

[0014] Furthermore, it also includes:

[0015] The mud hole is arranged on one side of the lower part of the scraper close to the T-connector, the mud hole is in an arc shape, and the center of the mud hole is located below the lower edge of the scraper.

[0016] Furthermore, it also includes:

[0017] The mudguard is fixedly connected to the front surface of the scraper, and the plane parallel to the scraper and the cross section of the mudguard are arc-shaped cross sections. The greater the distance between the arc-shaped cross section and the scraper, the greater the radius of the arc-shaped cross section.

[0018] Furthermore, the greater the distance between the arc-shaped cross section and the scraper, the higher the center of the arc-shaped cross section.

[0019] Furthermore, it also includes:

[0020] A water spray pipe, wherein the water spray pipe comprises two water spray pipes, one for each scraper, and the water outlet of the water spray pipe is located at the front of the scraper, and the front of the scraper is the side having the same movement direction as the scraper when working;

[0021] An intermittent nozzle is communicated with a water outlet of a water spray pipe, and a pipe body of the water spray pipe is fixedly connected to the back of the scraper.

[0022] Furthermore, the intermittent nozzle comprises:

[0023] The cover body is cylindrical, the bottom of the cover body closes the water outlet connected to the water spray pipe at the top, and the side of the cover body has more than one release hole connected to the inner and outer walls of the cover body;

[0024] The rotor matches the cavity in the cover body, the rotor is rotatably connected in the cavity in the cover body, a nozzle is opened on the side of the rotor, the direction of water spraying from the nozzle does not pass through the center of the rotor, the nozzle is connected with the water outlet of the water spray pipe, and the rotor rotates so that the nozzle is closed by the side wall of the cover body and opens in the release hole.

[0025] The beneficial effects of the present invention are: compared with the prior art,

[0026] 1) The present invention connects two scrapers through a T-type connector, and then connects a ridger through the mounting hole on the T-type connector. When the ridger is started, the scraper is pulled forward by the ridger. Since the arc-shaped scraping holes on the scraper directly scrape the ridge body, the surface of the ridge body is shaped by the scraper. The shape of the ridge body is the shape of the scraping holes. The ridge body is fuller and is formed in one time without manual secondary operation, so the labor cost is low. After the scraping holes shape the ridge body, if there are small stones or relatively hard soil blocks on the ridge body, the scraper at the scraping holes may scrape marks on the surface of the ridge body, making the surface of the ridge body uneven. The marks on the ridge body scraped by the scraper can be flattened by the mud pressing board to eliminate the scratches.

[0027] 2) The radius of the mud pressing plate in the present invention gradually decreases as it moves away from the scraper, so that the soil entering the lower part of the scraper is compacted by the mud pressing plate during the process of the scraper moving forward, and as the mud pressing plate moves forward, the pressure of the mud pressing plate on the fixed position on the ridge body under the mud pressing plate becomes greater and greater, so that the deep scratches on the ridge body surface can be eliminated, and the soil on the ridge body surface is more compacted;

[0028] 3) Since different soil types or crops have different requirements for the furrowing width of the ridge body, the existing furrowing accessories cannot adjust the furrowing width according to actual needs. In the present invention, a connecting rod is inserted into the inner cavity of the insert tube, a screw hole is provided on the side wall of the insert tube, and a fixing bolt is threadedly connected to the screw hole. The fixing bolt is tightened or loosened to fix or loosen the position of the connecting rod and the insert tube, thereby adjusting the distance between the two scrapers, so that the furrowing width of the ridge body can be adjusted according to actual conditions;

[0029] 4) Since the force direction of the scraper is perpendicular to the scraper surface, the scraper is easily deformed by force. The reinforcing ribs are fixedly connected to the back of the scraper and are vertically oriented, so that the bending resistance of the scraper in the vertical direction is improved. At the same time, the reinforcing ribs are angle steels, so that the bending resistance of the reinforcing ribs is enhanced. The present invention connects the mud pressing plate and the scraper through ribs, so that the structure of the ribs and the scraper is strengthened, and the bending of the mud pressing plate is avoided, which causes irregular ridge formation;

[0030] 5) The present invention uses mud holes to allow the scraper to shape the soil in the ditch while shaping the ridge, so that a small "ridge" can be formed in the ditch, so that when covering the film, the soil on the small "ridge" can be covered to the edge of the film, which is convenient for covering the film;

[0031] 6) The present invention uses a mud guard so that the soil in the front of the scraper body can be pushed onto the upper part of the ridge body by the guiding effect of the scraper body during the forward movement of the scraper body, so that the possible indentations on the ridge body are covered with enough soil, and the soil in the ditch body is continuously pushed onto the ridge body, so that the soil in the ditch body will not accumulate in large quantities to increase the resistance of the scraper, thereby reducing the oil consumption of the ridger, and in addition, the deformation of the scraper is reduced, thereby increasing the service life of the scraper;

[0032] 7) As the distance between the arc section and the scraper body increases, the center of the arc section increases. Therefore, the mud guard at the bottom exerts greater pressure on the soil than the mud guard at the top. As the scraper body moves forward, the soil under the mud guard will be pushed to the upper part of the ridge by the mud guard, further increasing the power of the mud guard to push the soil net in the ditch body.

[0033] 8) The present invention arranges a water spray pipe at the front of the scraper. When the scraper is working, the water spray pipe sprays water to the ridge body, so that the soil on the ridge body has stronger viscosity. After the soil is sprayed with water, the ridge body is more solid after being compacted by the mud pressing plate. When working, high-pressure water is connected to the water spray pipe, and the water in the water spray pipe is sprayed intermittently through the gap nozzle, so that a water hammer effect is formed in the water spray pipe, causing the water spray pipe to vibrate. Since the water spray pipe is fixedly connected to the scraper, the mud pressing plate on the scraper will also vibrate, so that the mud pressing plate has a better compaction effect on the ridge body, making the ridge body more compact. The pipe body of the water spray pipe is fixedly connected to the back of the scraper, so that the soil will not contact the water spray pipe and damage the water spray pipe;

[0034] 9) The present invention connects the rotor to the cavity in the cover body through rotation. Since the water spraying direction of the rotor nozzle does not pass through the center of the rotor, the high-pressure water will exert a rotational torque on the rotor after passing through the nozzle, thereby automatically driving the rotor to rotate inside the cover body without the need for external energy. The rotation of the rotor causes the nozzle to be continuously blocked by the side wall of the cover body and open at the release hole, so that water is sprayed out from the gap of the gap nozzle, generating a water hammer effect on the water spray pipe, causing the mud press plate to vibrate.
