Description

Technical Field

[0001] The present invention relates to the technical field of agricultural cultivation machinery, and more particularly to a film covering and punching device for angelica planting. Background Art

[0002] Mulching refers to the process of covering the soil surface with a thin film (such as plastic mulch, biodegradable film, etc.) during crop cultivation to improve the crop growth environment, increase yield and quality. In order to resolve the contradiction between crop growth needs and closed coverage, it is necessary to punch holes on the surface of the mulch. Mulch punchers are commonly used mechanical equipment in modern agriculture for precisely opening holes in mulch to facilitate sowing, transplanting or ventilation. They can significantly improve planting efficiency and reduce labor costs. To plant angelica, you need to choose cool, moist, fertile uncultivated or cultivated land. The soil layer must be deep, fertile, loose, and sandy loam rich in humus. When drilling holes in this type of soil, clods of soil will adhere to the punching needles, causing the punching needles to be blocked, increasing the weight of the punching needles, and increasing the power to drive the punching, resulting in additional power consumption. Moreover, during the rotating drilling process, the punching needles are very likely to be pulled against the ground film, and the ground film is easily torn by the punching needles, thereby reducing the thermal insulation effect of the ground film. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a film covering and punching device for Angelica sinensis planting to solve the problems existing in the above-mentioned background technology.

[0004] To achieve the above object, the present invention provides the following technical solution: a film-covered punching device for angelica planting, comprising a punching assembly, wherein the punching assembly comprises a roller assembly, the top of which is fixedly connected to a plurality of hole needle assemblies, the roller assembly comprises a cylinder, and the bottom of the cylinder is equipped with an arc-shaped pressure plate; The middle of the inner side of the two arc-shaped pressure plates is fixedly connected with a compression rod 1, the side surfaces of the two compression rods 1 are movably connected with a round tube, the bottoms of the two round tubes are fixedly connected to the inner sides of the two ends of the bottom of the cylinder, the inner sides of the top ends of the two round tubes are movably connected with a compression rod 2, the top ends of the two compression rods 2 are fixedly connected with a connecting plate, and the top of the connecting plate is fixedly connected with a plurality of support rods; The support rod moves up and down and cooperates with the hole needle assembly to avoid tearing the ground film when the soil is extracted, and the arc-shaped pressure plate is linked with the support rod to cooperate with the hole needle assembly to dredge the hole needle assembly.

[0005] Furthermore, the bottom of the punching assembly is fixedly connected to an inner support assembly, and both ends of the punching assembly are fixedly connected to a driving assembly.

[0006] Furthermore, both ends of the drum assembly are fixedly connected with a rotating shaft, and the sides of the two rotating shafts are fixedly sleeved with a blowing fan.

[0007] Furthermore, a number of square hole grooves are provided on both sides and the bottom of the cylinder. Side covers are fixedly connected to both ends of the cylinder. A number of round holes are provided on the outer peripheral edge of the side covers, and a number of sector holes are provided in the middle of the side covers. A number of hole needle assemblies are fixedly communicated with the top of the cylinder.

[0008] Furthermore, the hole needle assembly includes a limiting shaft, which is composed of an inner shaft and an outer tube sleeve. The outer tube sleeve is rotatably sleeved on the side surface of the inner shaft. Two movable grooves are provided on the side surfaces at both ends of the outer tube sleeve, and the lengths of both movable grooves are one-fourth of the cross-sectional circumference of the outer tube sleeve.

[0009] Furthermore, a tip needle is fixedly connected to the top of the outer tube sleeve. Connecting bars are fixedly connected to the bottoms of both ends of the inner shaft. A base needle is fixedly connected to the bottom end of the connecting bar, and both connecting bars pass through the movable grooves.

[0010] Furthermore, the inner support assembly includes two arc-shaped pressing plates. Springs are fixedly connected to the inner sides of both compression rods one. The top ends of both springs are fixedly connected to the bottom of the cylinder. Both springs are wrapped around the side surface of the bottom end of the compression rod one. Exhaust holes are provided on the front and back of the tops of both round tubes.

[0011] Furthermore, the number of the support rods is the same as that of the hole needle assemblies. The support rods penetrate through the inner wall of the cylinder, and the support rods move inside the tip needle and the base needle.

[0012] Furthermore, the driving assembly includes a mounting frame. Fixed plates are fixedly connected to the bottoms of both sides of the mounting frame. Rotating shafts are rotatably connected to the opposite sides of both fixed plates. A striking rod is fixedly connected to the inner side of the mounting frame. A motor is fixedly sleeved on the back of the mounting frame, and a first transmission belt is fixedly connected to the driving end of the motor. The bottom end of the first transmission belt is movably sleeved on a shaft pulley, and a second transmission belt is movably sleeved on the side surface of one end of the shaft pulley.

[0013] Furthermore, a rotating shaft is movably sleeved on one end of the second transmission belt. The shaft pulley is rotatably sleeved on the bottom of the back of the mounting frame. Wheels are fixedly connected to both ends of the shaft pulley. Wheels are fixedly connected to both sides of the front bottom of the mounting frame.

[0014] The technical effects and advantages of the present invention: The tip needle and the base needle are laterally fixed by a support rod so that they will not bend when contacting the ground, which affects hole punching. When the tip needle enters the soil, the soil will enter the tip needle and squeeze the support rod downward, causing the upper end of the support rod to leave the inside of the tip needle. The tip needle and the base needle lose lateral fixation. When the tip needle leaves the soil due to the rotation of the drum assembly, there is a lateral force on the tip needle from the soil, causing the hole needle assembly to bend. At the moment of emerging from the soil, the tip needle is vertically pulled out from the soil surface and the plastic film surface, without pulling on the plastic film, avoiding the problem that the plastic film is easily torn by the punching needle and reducing the heat preservation effect of the plastic film.

[0015] [[ID= 3]]After the hole needle assembly finishes hole punching and the tip needle withdraws from the soil, due to the wet and loose characteristics of the soil, the soil will adhere to the inner wall of the tip needle and cause blockage, increasing the weight of the punching needle and the power required to drive the punching. When the drum assembly rotates and the inner support assembly squeezes the ground, the tip needle is at the top of the cylinder. The extrusion of the drum against the ground forces the compression rod one into the round tube, increasing the air pressure in the round tube and pushing the compression rod two upward. As a result, the support rod moves upward. The upward movement of the support rod dislodges the soil block in the tip needle and re-fixes the tip needle and the base needle. This process solves the problem of additional power consumption caused by soil blockage of the punching needle. Description of the Drawings

Detailed implementation manners

[0018] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. In addition, the forms of each structure described in the following embodiments are only examples. A film mulching and punching device for angelica planting involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0019] Refer to Figure 1 , the present invention provides a film mulching and punching device for angelica planting, including a punching component 1. The bottom of the punching component 1 is fixedly connected with an inner support component 2, and both ends of the punching component 1 are fixedly connected with a driving component 3.

[0020] Specifically, in this embodiment, it should be noted that the punching component 1 avoids the problem that the plastic film is easily torn by the punching needle and the heat preservation effect of the plastic film is reduced. The inner support component 2 solves the problem that the punching needle is blocked by the soil, resulting in additional power consumption. The specific structures and working principles of the above components will be described in detail later.

[0021] Refer to Figure 2 , the punching component 1 includes a roller component 101. The top of the roller component 101 is fixedly communicated with a plurality of hole needle components 102. Both ends of the roller component 101 are fixedly connected with rotating shafts, and both sides of the two rotating shafts are fixedly sleeved with blowing fans 103.

[0022] Specifically, in this embodiment, it should be noted that there are five hole needle components 102 in this embodiment. The layout of the five hole needle components 102 is based on the planting row spacing (usually 30 - 40 cm) and plant spacing (20 - 25 cm) of the standard angelica ridge, but it is not limited to five, and can be set according to the actual planting requirements of the angelica ridge. The blowing fans 103 located at both ends of the roller component 101 are arranged oppositely. When the roller component 101 rotates, the wind formed by the two blowing fans 103 blows towards the inside of the roller component 101, gathering the soil ash entering the roller component 101 towards the middle of the roller component 101, promoting the discharge of the soil ash from the roller component 101; The blade inclination angle of the blowing fan 103 is 25°, and the rotational speed is 300 - 400 rpm (synchronized with the drum assembly 101), generating an axial air flow with a wind speed ≥ 8 m / s. The double blowing fans blowing towards each other can form a low-pressure area in the middle of the drum (pressure difference about 50 Pa), increasing the efficiency of the soil ash moving towards the middle by 60% (compared with the design without blowing fans). Under the working condition with a soil content of 20%, the blowing fan design can reduce the ash accumulation amount on the inner wall of the drum assembly 101 by 70%, preventing the deposition of soil ash in the drum assembly 101, reducing the mechanical load, and thus saving energy consumption.

[0023] Refer to Figure 3 As shown, the drum assembly 101 includes a cylindrical barrel 1011. A number of square hole grooves are provided on both sides and the bottom of the cylindrical barrel 1011. Both ends of the cylindrical barrel 1011 are fixedly connected with side baffle covers 1012. A number of circular holes are provided on the outer peripheral edge of the side baffle cover 1012, and a number of sector holes are provided in the middle of the side baffle cover 1012. A number of hole needle assemblies 102 are fixedly communicated with the top of the cylindrical barrel 1011.

[0024] In this embodiment, it should be specifically supplemented that five square hole grooves are provided on both sides and the bottom of the cylindrical barrel 1011 for discharging the soil ash entering it when the cylindrical barrel 1011 rotates. The side baffle cover 1012 is provided with eight circular holes and four sector holes. The diameter of the eight circular holes is 20 mm, mainly guiding the air flow axially to enter and forming an initial wind pressure (wind speed 5 m / s). The central angle of the four sector holes is 45°, generating a rotating air flow (tangential wind speed 3 m / s). After being superimposed with the air flow of the circular holes, a spiral wind field is formed, extending the moving path of the soil ash towards the square hole grooves by 30% and improving the separation effect, enabling the air flow generated by the blowing fan 103 to enter the cylindrical barrel 1011 and blowing the soil ash towards the square hole grooves for discharge. The number of square hole grooves, square holes, and sector holes is not limited to the above numbers and can be set according to actual planting requirements; There are five square hole grooves on each of the two sides and the bottom (15 in total), and the groove opening size is preferably 30 mm × 50 mm (length × width). According to field tests, this size can balance the ash discharge efficiency (≥ 85%) and the structural strength (stress concentration factor < 1.8). When the rotational speed of the drum is 300 rpm, the soil ash discharge flow rate of the square hole grooves is 2.1 kg / s (dry soil working condition). If the moisture content of the soil ash > 15%, the groove opening needs to be increased to 40 mm × 60 mm to avoid adhesion. The spacing between the bottom square hole grooves is 150 mm (matching the lateral spacing of the hole needle assemblies 102) to ensure that the soil falling after punching can directly pass through the corresponding groove openings for discharge. The side groove openings are designed with a 15° inclination to assist ash discharge using centrifugal force (efficiency increased by about 25%).

[0025] Refer to Figure 4, the hole needle assembly 102 includes a limit shaft 1021 which consists of an inner shaft and an outer tube sleeve. The outer tube sleeve is rotatably sleeved on the side of the inner shaft. Two movable slots are provided on the sides at both ends of the outer tube sleeve, and the length of each of the two movable slots is one-fourth of the cross-sectional circumference of the outer tube sleeve. A tip needle 1022 is fixedly connected to the top of the outer tube sleeve. Connecting bars are fixedly connected to the bottoms of both ends of the inner shaft, and a base needle 1023 is fixedly connected to the bottom end of each connecting bar. The two connecting bars pass through the movable slots.

[0026] In this embodiment, it should be specifically noted that the length of each of the two movable slots is one-fourth of the cross-sectional circumference of the outer tube sleeve, that is, an arc length of 90°. The connecting bar forms a mechanical hard stop at the end of the movable slot to prevent reverse rotation. When the tip needle 1022 rotates, the outer sleeve rotates with the tip needle 1022, causing the connecting bar to move relatively in the movable slot. Due to the limitation of the movable slot and the connecting bar, the tip needle 1022 can only rotate in one direction, and thus the hole needle assembly 102 can only be bent unidirectionally.

[0027] Refer to Figure 5 and Figure 6 , the inner support assembly 2 includes two arc-shaped pressing plates 201 which are installed at the bottom of the cylinder 1011. Compression rods 202 are fixedly connected to the middle of the inner sides of the two arc-shaped pressing plates 201. The sides of the two compression rods 202 are rotatably sleeved with round tubes 203. The bottoms of the two round tubes 203 are fixedly communicated with the inner sides at both ends of the bottom of the cylinder 1011. Springs are fixedly connected to the inner sides of the two compression rods 202, and the top ends of the two springs are fixedly connected to the bottom of the cylinder 1011. The two springs are both wrapped around the side of the bottom end of the compression rod 202. Exhaust holes are provided on the front and back of the tops of the two round tubes 203. Compression rods 204 are rotatably sleeved on the inner sides of the tops of the two round tubes 203. A connecting plate 205 is fixedly connected to the top ends of the two compression rods 204. A plurality of support rods 206 are fixedly connected to the top of the connecting plate 205. The number of the support rods 206 is the same as that of the hole needle assemblies 102. The support rods 206 penetrate through the inner wall of the cylinder 1011 and move inside the tip needle 1022 and the base needle 1023. The support rod 206 fixes the tip needle 1022 and the base needle 1023 laterally so that they will not bend when in contact with the ground, which will affect the drilling. When the tip needle 1022 enters the soil, the soil will enter the tip needle 1022 and squeeze the support rod 206 downward, so that the upper end of the support rod 206 leaves the interior of 122, and the tip needle 1022 and the base needle 1023 lose their laterally fixed position. When the tip needle 1022 leaves the soil due to the rotation of the roller assembly 101, the soil exerts a lateral force on the tip needle 1022, causing the hole needle assembly 102 to bend, so that at the moment of being unearthed, the tip needle 1022 is pulled out vertically from the soil surface and the ground film surface, without pulling the ground film, thereby avoiding the problem that the ground film is easily torn by the punching needle and reduces the thermal insulation effect of the ground film; After the hole needle assembly 102 completes the drilling, the tip needle 1022 is pulled out of the soil. Due to the moist and loose nature of the soil, the soil will adhere to the inner wall of the tip needle 1022 and cause blockage, which increases the weight of the tip needle 1022 and the power to drive the hole needle assembly 102. When the roller assembly 101 rotates to squeeze the inner support assembly 2 against the ground, the tip needle 1022 is at the top of the cylinder 1011, and the compression of the cylinder 1011 and the ground causes the compression rod 202 to be squeezed in. The circular tube 203 increases the air pressure in the circular tube 203 and pushes the second compression rod 204 upward. The connecting plate 205 is fixedly connected to the second compression rod 204, and the support rod 206 is fixedly connected to the connecting plate 205, thereby causing the support rod 206 to move upward. The upward movement of the support rod 206 pounded out the soil in the tip needle 1022 and re-fixed the tip needle 1022 and the base needle 1023. This process solves the problem of soil clogging the punching needles and causing additional power consumption. The arc-shaped pressure plate 201 is made of 65Mn spring steel with a hardness of HRC45-50, ensuring wear resistance and good elastic recovery when in contact with the ground. The compression rod 202 has a diameter of 20mm, a stroke of 50mm, and an exhaust hole diameter of 5mm, ensuring that air is quickly discharged when the compression rod 202 is pressed down and external air is replenished during rebound. The support rod 206 has a diameter of 8mm (material 60Si2MnA) to ensure rigidity and the ability to withstand lateral forces from the soil. The upward stroke of the support rod 206 is the length of the inner cavity of the tip needle 1022, approximately 60mm, to ensure that the adhering soil is completely pounded out.

[0028] Reference Figure 7 and Figure 8, the driving component 3 includes a mounting frame 301. Fixedly connected to the bottom of both sides of the mounting frame 301 are fixing plates 302. Rotatably connected to the opposite sides of the two fixing plates 302 are rotating shafts. Fixedly connected to the inner side of the mounting frame 301 is a striking rod 303. Fixedly sleeved on the back of the mounting frame 301 is a motor 304. The driving end of the motor 304 is fixedly connected to a first transmission belt 305. The bottom end of the first transmission belt 305 is movably sleeved with a pulley. The side of one end of the pulley is movably sleeved with a second transmission belt 306. One end of the second transmission belt 306 is movably sleeved with a rotating shaft. The pulley is rotatably sleeved at the bottom of the back of the mounting frame 301. Fixedly connected to both ends of the pulley are wheels. Fixedly connected to both sides of the bottom of the front end of the mounting frame 301 are wheels.

[0029] In this embodiment, it should be specifically noted that the motor 304 is a 0.5kW servo motor. The first transmission belt 305 is the main transmission belt, with the type of synchronous belt (HTD-5M, bandwidth 20mm) to avoid slipping and the transmission efficiency ≥98%. The second transmission belt 306 is the driven belt, with the type of V-belt to compensate for the impact load of the punching component 1 by elastic deformation. The motor 304 drives the first transmission belt 305 to rotate, thereby driving the pulley to rotate, providing power for the driving component 3 to move the whole device. The rotation of the pulley then drives the punching component 1 to rotate through the second transmission belt 306 to punch holes in the plastic film. When the tip needle 1022 rotates to the position of the striking rod 303, an impact is formed with the striking rod 303, and the impact vibration further shakes off the soil ash adhering to the inner wall of the tip needle 1022.

[0030] The working principle of the present invention: The motor 304 drives the driving component 3 to move forward stably. The rotation of the pulley then drives the punching component 1 to rotate through the second transmission belt 306. The support rod 206 laterally fixes the tip needle 1022 and the base needle 1023 so that they will not bend when contacting the ground, affecting the punching. When the tip needle 1022 enters the soil, the soil will enter the tip needle 1022 and squeeze the support rod 206 to move downward, causing the upper end of the support rod 206 to leave the inside of 122. The tip needle 1022 and the base needle 1023 lose lateral fixation. When the tip needle 1022 leaves the soil due to the rotation of the roller component 101, there is a lateral force on the tip needle 1022 from the soil, causing the hole needle component 102 to bend. When it exits the soil, the tip needle 1022 is perpendicularly pulled out from the soil surface and the plastic film surface, without pulling on the plastic film, avoiding the problem that the plastic film is easily torn by the punching needle and reducing the heat preservation effect of the plastic film. After the hole-punching needle assembly 102 finishes punching holes, the tip needle 1022 is withdrawn from the soil. Due to the wet and loose characteristics of the soil, the soil will adhere to the inner wall of the tip needle 1022 and cause blockage, increasing the weight of the tip needle 1022 and the power required to drive the hole-punching needle assembly 102. When the roller assembly 101 rotates to make the inner support assembly 2 press against the ground, the tip needle 1022 is at the top of the cylinder 1011. The extrusion of the cylinder 1011 against the ground causes the compression rod 1 202 to be pushed into the round tube 203, increasing the air pressure in the round tube 203 and pushing the compression rod 2 204 upward. The connecting plate 205 is fixedly connected to the compression rod 2 204, and the support rod 206 is fixedly connected to the connecting plate 205, thus causing the support rod 206 to move upward. The upward movement of the support rod 206 dislodges the soil block in the tip needle 1022 and re-fixes the tip needle 1022 and the base needle 1023. This process solves the problem of additional power consumption caused by soil blockage of the punching needle.
