Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, and specifically relates to a carrot harvester with good soil crushing effect. Background Technique

[0002] The carrot planting area in China is close to 40% of the total world carrot planting area, and the total output accounts for about 1 / 3 of the world's total output. China is the world's largest carrot producer. However, the degree of harvesting mechanization and automation is low, and the traditional manual harvesting method is still mainly used, which requires a large amount of manpower, time-consuming, material-consuming and labor-consuming. The low harvesting efficiency has become a bottleneck restricting the improvement of the planting efficiency of the carrot industry. Although there are imported integrated harvesters from abroad that can realize operations such as excavation, conveying, and root-leaf separation, due to China's vast territory, complex terrain, and non-standard domestic agronomic requirements, etc., the large-scale carrot harvesting machinery imported from abroad cannot well meet the domestic needs; while the domestically developed carrot harvesters, although having functions such as vibration, conveying, and stem and leaf cutting, can improve production efficiency to a certain extent, but have the disadvantages of complex design and unstable harvesting, and it is difficult to avoid the contact and friction between the machine and the carrot fleshy roots, resulting in damage to the epidermis of the fleshy roots and cannot be used for long-term cold storage.

[0003] In the technical solution previously designed by the author's team (Chinese utility model patent: CN214385116U, a carrot harvester with a soil loosening function), a plurality of plowshares arranged side by side are fixedly arranged on the bottom beam. The shape of the plowshare is arrow-shaped, with a pointed front end and a small thickness, and a straight rear end and a large thickness. The plowshare is fixedly installed on the bottom beam obliquely through a positioning sleeve; when in use, the plowshare is inserted into the soil, and when the tractor drags the harvester to move forward as a whole, the plowshare continuously lifts the soil, and under the resistance of the soil in front, the lifted soil slides backward along the surface of the plowshare, and then crosses over the top of the bottom beam and falls on the vibration separation component behind, thereby realizing the crushing of the soil and the separation of the carrots from the soil. In this technical solution, the vibration transmission component uses a cam push rod mechanism to convert the rotational motion of the rotating shaft into the horizontal reciprocating motion of the push rod, and then uses a crank-slider mechanism composed of the push rod and the swing rod to convert the horizontal reciprocating motion of the push rod into the up-and-down reciprocating swing motion of the swing rod in the vertical plane, thereby driving the separation rod to swing up and down reciprocally to impact and crush the soil falling on it.

[0004] However, the author found in actual use that the technical effect of this technical solution still has some shortcomings: first, since the soil is forced to be pushed to the rear side, the bottom soil is often relatively moist and has strong adhesion, so it is easy for the soil to accumulate on the plow shovel and then be directly discharged from both sides, and cannot smoothly reach the vibration separation component on the rear side; secondly, since the soil is forced to be pushed to the rear side and naturally slides onto the vibration separation component, the vertical drop of the soil is small, the impact and crushing effect is poor, and the separation effect of the vibration separation component cannot be fully demonstrated; thirdly, in this technical solution, the reciprocating swing frequency of the rocker arm is the same as the rotation frequency of the roller. Since the rotation frequency of the roller is low, the impact effect between the soil and the separation rod is poor. At the same time, since the horizontal reciprocating motion distance of the top rod is limited, the swing amplitude of the rocker arm after transmission is not large, and the impact force and shaking-off effect between the separation rod and the soil are also poor. Utility Model Content

The utility model adopts the method of actively digging soil and carrots and throwing them to the rear side, so as to facilitate the subsequent soil impact crushing and separation of carrots from the soil. While reducing the damage to the fleshy roots of carrots, it can effectively crush larger soil blocks. The sprocket drive and crank slider mechanism are used to realize power transmission, and high-frequency and large-scale impact crushing of the soil can be realized, so that the soil is crushed more fully and thoroughly.

[0006] In order to achieve the above effects, the technical solution adopted by the utility model is:

[0007] A carrot harvester with good soil crushing effect, comprising a horizontal support, side plates fixedly connected to the bottoms of both sides of the horizontal support, and a connecting frame fixedly connected to the top of the horizontal support, characterized in that a rotating shaft is rotatably installed between the bottoms of the two side plates, a plowshare assembly is fixedly arranged on the rotating shaft, the plowshare assembly comprises a sleeve sleeved on the outer side of the rotating shaft, and plowshare groups arranged and distributed along the axis of the sleeve, and each plowshare group comprises a plurality of plowshares uniformly distributed circumferentially around the circumferential surface of the sleeve;

[0008] A roller is rotatably mounted on the outer side of each side plate, and one end of the rotating shaft is transmission-connected to the rotating shaft of one of the rollers through a gear pair;

[0009] Vibration transmission components are fixedly installed at the shaft diameters at both ends of the rotating shaft, and the vibration transmission component includes a driving sprocket fixedly installed on the rotating shaft of the rotating shaft, a driven sprocket rotatably installed on the inner wall of the side plate, and a chain that transmits and connects the driving sprocket and the driven sprocket, a turntable is fixedly connected to the inner end face of the driven sprocket, an eccentric shaft is fixedly installed at the end face edge of the turntable, and a vibration separation component rotatably installed between the two side plate ends is movably connected to the eccentric shaft.

[0010] Further, the plow share includes an arc-shaped connecting plate that matches the outer cylindrical surface of the sleeve and a shovel blade fixedly arranged in the middle of the outer surface of the arc-shaped connecting plate. The thickness and width of the shovel blade gradually decrease in the direction away from the arc-shaped connecting plate, and the upper surface of the shovel blade is a concave arc surface.

[0011] Further, at least one strip-shaped through groove is formed inside the shovel blade.

[0012] Further, the vibration separation assembly includes a swing rod rotatably connected to the inner wall of the side plate and a swing beam fixed between the ends of the two swing rods. One end of the swing rod away from the swing beam is connected to an eccentric shaft, and a plurality of separation rods are fixedly connected to the top of the swing beam.

[0013] Further, the separation rods are evenly and obliquely distributed on the swing beam, and the higher end of the separation rod is close to the sleeve and is located below the outer cylindrical surface side of the sleeve.

[0014] Further, the swing rod is a "Z"-shaped connecting rod, and the projections of the two end rod segments in the vertical plane form an inverted "V" structure. A waist-shaped through groove is formed on the rod segment of the swing rod away from the swing beam, and the eccentric shaft is located in the waist-shaped through groove.

[0015] Further, the plow shares and the separation rods are alternately distributed in the axial direction of the sleeve, and the plow shares can pass through the gap area between two adjacent separation rods during rotation.

[0016] Further, bearing seats are sleeved on the outer sides of the two end shafts of the rotating shaft, and the tops of the bearing seats are fixedly connected to the bottom surface of the horizontal bracket through suspension rods.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] 1. By adopting the plow share assembly with an arc-shaped structure and continuous rotation in sequence, the present utility model adopts the method of digging the carrots together with the soil from the root part as a whole, actively lifts and throws the soil and the carrots inside it in a segmented and continuous manner to the rear side, which helps the soil to fall and impact on the separation assembly, enabling the soil to be fully broken, so as to separate the carrots from the soil, thereby realizing the loosening of the rhizosphere soil of the carrots while reducing the direct contact between the fleshy roots of the carrots and the machine; the amount of soil carried on the surface of the carrots is small, the damage rate of the carrot epidermis is low, and the harvested carrots can be sold immediately or stored in a cold storage.

[0019] 2. The utility model realizes the transmission and drives the vibration separation component to swing reciprocally through the vibration transmission component formed by the sprocket transmission mechanism and the eccentric connecting rod transmission mechanism by arranging the vibration separation component behind the plowshare component, which can actively break the large soil blocks falling above it, greatly improving the soil breaking rate. At the same time, this form of power transmission can enable the vibration separation component to swing reciprocally with high frequency and large amplitude, thus ensuring the sufficiency of soil breaking and the degree of soil peeling on the surface of carrots, realizing the separation of carrots from the soil. The separated carrots can roll backward along the vibration separation component and be scattered on the surface of the soil, facilitating the picking of carrots.

[0020] 3. The utility model has a simple structure and is convenient to use, which can synchronously realize the harvesting of carrots and the breaking of soil, greatly improving the working efficiency of carrot harvesting and reducing the cost investment. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0034] The following will elaborate on the preferred embodiments of the present invention in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0035] Please refer to Figures 1 to 11 , a carrot harvester with good soil-breaking effect, including a horizontal bracket 1, side plates 2 fixedly connected to the bottoms of both sides of the horizontal bracket 1, and a connecting frame 101 fixedly connected to the top of the horizontal bracket 1. The horizontal bracket 1 is a square frame welded by square pipes; the side plates 2 are vertically arranged and fixedly connected to the two ends of the horizontal bracket 1 by bolts or welding. The connecting frame 101 is composed of a V-shaped frame plate and an auxiliary rod. The two bottom ends of the V-shaped frame plate and the bottom end of the auxiliary rod are respectively connected to the connecting ear seats on the top of the horizontal bracket 1 by pins, and the top end of the V-shaped frame plate and the top end of the auxiliary rod are connected by pins, thus forming a triangular connecting frame; a hanging ring is arranged on the top of the connecting frame 101 for mating connection with a tractor to drive the entire harvester to work.

[0036] A rotating shaft 4 is rotatably installed between the bottoms of the two side plates 2. The two ends of the rotating shaft 4 are respectively rotatably installed in the two side plates 2 through rolling bearings (not shown in the figure), so that the rotating shaft 4 is horizontally arranged rotatably and perpendicular to the traveling direction of the harvester. A roller 5 is rotatably installed on the outer side of each side plate 2, and one end of the rotating shaft 4 is in transmission connection with the rotating shaft of one of the rollers 5 through a gear pair. Preferably, the circumferential surface of the roller 5 adopts a gear structure or a tire structure to enhance the biting force between the roller 5 and the soil surface, so that the roller 5 keeps rolling continuously during the traveling process. As Figure 5 shown, the center of the inner end face of the roller 5 is fixedly connected with a wheel shaft (not shown in the figure), the shaft end of the wheel shaft is rotatably installed at the front end of the bottom of the side plate 2 through a rolling bearing, and a bearing end cover 12 fixedly connected to the inner wall of the side plate 2 by bolts is arranged outside the rolling bearing to prevent the soil lifted during the working process of the harvester from entering the rolling bearing and affecting the normal use and service life of the rolling bearing. One of the rollers 5 (such asFigure 1 A driving gear 10 is fixedly sleeved on the axle of the one shown on the left side, and a driven gear 11 meshing with the driving gear 10 is fixedly sleeved on the end of the corresponding same-side end of the rotating shaft 4. When the hydraulic system on the tractor presses down the harvester and drags the harvester forward, the roller 5 rolls forward in the counterclockwise direction at the angle shown on the Figure 1 ground surface, and the driving gear 10 rotates synchronously with the roller 5, so as to drive the driven gear 11 to transmit synchronously in the clockwise direction, and then the driven gear 11 drives the rotating shaft 4 to rotate synchronously. The number of teeth of the driving gear 10 is greater than the number of teeth of the driven gear 11, so a speed-increasing transmission is formed, enabling the rotating shaft 4 to rotate at a relatively high speed.

[0037] A plowshare assembly 3 is fixedly arranged on the rotating shaft 4. As shown in Figure 6 the figure, the plowshare assembly 3 includes a sleeve 301 sleeved outside the rotating shaft 4 and a plowshare group arranged along the axis of the sleeve 301. Each plowshare group includes a plurality of plowshares 302 circumferentially and evenly distributed around the circumferential surface of the sleeve 301. The sleeve 301 is a hollow cylindrical structure, which is integrally sleeved outside the middle section of the rotating shaft 4 and is fixedly connected to the surface of the rotating shaft 4 by bolts. As shown in Figure 7 the figure, the plowshare 302 includes an arc-shaped connecting plate 3021 matching the outer circular surface of the sleeve 301 and a cutter 3022 fixedly arranged in the middle of the outer surface of the arc-shaped connecting plate 3021. Bolting holes are correspondingly formed on both sides of the arc-shaped connecting plate 3021 and on the outer circular surface of the sleeve 301, and the arc-shaped connecting plate 3021 is fixedly connected to the sleeve 301 by bolts. A plurality of (such as Figure 6 4 shown in the figure) plowshares 302 are evenly distributed on the circumferential surface of the sleeve 301 to form a plowshare group, and a plurality of (such as Figures 1 to 4 10 shown in the figure) plowshare groups are arranged in sequence to form the plowshare assembly. The bolt connection method facilitates the assembly and disassembly of the cutter 3022. The thickness and width of the cutter 3022 gradually decrease in the direction away from the arc-shaped connecting plate 3021, and the upper surface of the cutter 3022 is a concave arc surface. Thus, during the operation of the harvester, since the radius of the cutter 3022 is greater than the radius of the roller 5, the end of the cutter 3022 can be inserted into the soil to a certain depth (selected according to the maximum root soil penetration depth of carrots). When the plowshare assembly rotates continuously at a high speed driven by the rotating shaft 4, the cutters 3022 in the same column lift the soil and the carrots inside forward from the rear lower part of the soil, and the cutters 3022 in the next column perform the same soil shoveling process progressively; when the cutters 3022 pass over the top of the rotating shaft 4 successively, the lifted soil and the carrots inside are thrown to the side or slide backward and downward along the surface of the cutter.

[0038] Preferably, at least one strip-shaped through groove 3023 is provided inside the blade 3022 to reduce the weight of the blade 3022 itself, while reducing the contact area between the soil and the blade surface, reducing the amount of soil adhering to the surface of the blade 3002, and also facilitating the discharge of some fragmented soil from the strip-shaped channel 3023 during the process of the blade 3022 lifting the soil. Further, bearing seats 8 are sleeved on the outer sides of the two ends of the rotating shaft 4, and the tops of the bearing seats 8 are fixedly connected to the bottom surface of the horizontal bracket 1 through suspension rods 9, so as to further enhance the stability of the rotating shaft 4 during operation.

[0039] Vibration transmission components 6 are fixedly installed at the shaft diameters of both ends of the rotating shaft 4. As Figure 9 shown, the vibration transmission component 6 includes a driving sprocket 601 fixedly arranged on the rotating shaft 4, a driven sprocket 602 rotatably installed on the inner wall of the side plate 2, a chain 603 drivingly connecting the driving sprocket 601 and the driven sprocket 602. A turntable 604 is fixedly connected to the inner end face of the driven sprocket 602, and an eccentric shaft 605 is fixedly arranged at the edge of the end face of the turntable 604. Mounting sleeves are integrally arranged on both end faces of the driving sprocket 601, and the mounting sleeves are sleeved on the rotating shaft 4 and fixed by bolt connection, so that the driving sprocket 601 can rotate synchronously with the rotating shaft 4. The shaft end of the driven sprocket 602 is rotatably installed in the inner side face of the side plate 2 through a rolling bearing, and a bearing end cover is arranged outside the rolling bearing. Through the meshing transmission of the chain 603, the driving sprocket 601 can drive the driven sprocket 602 to rotate synchronously in the same direction.

[0040] The eccentric shaft 605 is movably connected to a vibration separation component 7 rotatably installed between the ends of the two side plates 2. As Figure 10 and Figure 11 shown. The vibration separation component 7 includes a swing rod 701 rotatably connected to the inner wall of the side plate 2 and a swing beam 702 fixed between the ends of the two swing rods 701. The swing rod 701 is a "Z"-shaped connecting rod, and the projections of the two end rod segments in the vertical plane are in an inverted "V" structure. The middle of the rod segment of the swing rod 701 close to the swing beam 702 is installed on the inner wall of the side plate 2 through a pin shaft, so that the swing rod 701 can freely rotate around the pin shaft. A waist-shaped through groove 704 is provided on the rod segment of the swing rod 701 far from the swing beam 702, and the eccentric shaft 605 is located in the waist-shaped through groove 704, so that an eccentric connecting rod driving mechanism is formed among the turntable 604, the eccentric shaft 605 and the swing rod 701, converting the rotational motion of the turntable 604 into the reciprocating swing of the swing rod 701 in the vertical plane. Since the diameter of the turntable 604 can be based on the equipment and the swing amplitude of the swing rod 701 is large, it is beneficial to the fragmentation and falling of the soil, and also beneficial to the separation of carrots from the soil.

[0041] Multiple separating rods 703 are fixedly connected to the top of the swing beam 702. The separating rods 703 are evenly and obliquely distributed on the swing beam 702, and the higher ends of the separating rods 703 are close to the sleeve 301 and are located below the top surface of the bottom beam 3. So that the carrots and the root soil continuously lifted by the plowshare 302 pass above the sleeve 301 and are thrown or slide along the surface of the plowshare 302 and then fall on the multiple separating rods 703, and the process of soil fragmentation is completed during the falling and impact process. Since the thrown soil itself has a large impulse, when the soil impacts on the surface of the separating rods 703, better preliminary crushing can be obtained. During the process of the separating rods 703 reciprocating up and down following the swing beam 702, the crushing effect of the soil can be effectively enhanced, and at the same time, the carrots can be separated from the soil and stay on the top of the separating rods 703, and then fall to the rear of the harvester along the bottom of the top of the separating rods 703, and finally fall on the surface of the soil that has already scattered back to the ground, which is convenient for the picking of carrots. Preferably, a rubber sleeve (not shown in the figure) is sleeved outside the separating rods 703 to weaken the mechanical damage caused by the impact between the carrots falling on the separating rods 703 and the separating rods 703. Further preferably, in this embodiment, the number of teeth of the driving sprocket 601 is greater than the number of teeth of the driven sprocket 602, so that the rotational speed of the rotating shaft 4 is further increased and output, so that the swing rod 701 can swing at a higher frequency, thereby effectively increasing the number of impacts of the soil on the separating rods 703, ensuring the sufficiency of soil fragmentation and the sufficiency of soil peeling on the surface of the carrots.

[0042] Furthermore, the plowshare 302 and the separating rods 703 are alternately distributed in the axial direction of the sleeve 301, and the plowshare 302 can pass through the gap area between two adjacent separating rods 703 during rotation, and the distance between the end of the separating rod 703 and the surface of the sleeve 301 is relatively small. In this way, the lifted carrots and soil can be made to fall on the separating rods 703 as much as possible, so that more soil can be broken by vibration and separated from the carrots, which is beneficial to subsequent plowing operations and the picking of carrots, and reduces the amount of subsequent cleaning operations.

[0043] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
