In this way, the technical problem that the recovery of the prickly ash ears after cutting and harvesting in the prior art is basically dependent on manual transportation, and during manual transportation, the epidermis of the prickly ash ears is relatively sharp and can easily pierce the skin epidermis of farmers is solved.

[0032] The engagement member includes two semicircular toothed rings 111 , and the two semicircular toothed rings 111 are fixedly connected to the first slideway and the second slideway respectively.

[0035] For this specific embodiment, when the motor 105 drives the gear 106 to rotate, due to the fixity of the engagement member, the motor 105 will move along the direction of the rack, thereby driving the seat body 112 to move, and the seat body 112 thereby drives the bearings 113 to slide in the guide groove.

[0036] Meanwhile, the umbrella rib assembly includes an umbrella rib seat 114, two sliding balls 115, an outer umbrella rib 116 and an inner umbrella rib 117, the two sliding balls 115 are slidably connected to the slide track of the guide groove, the umbrella rib seat 114 is fixedly connected to the two sliding balls 115, and the outer umbrella rib 116 and the inner umbrella rib 117 are both on the umbrella rib seat 114;

[0037] The inner rib 117 and the outer rib 116 are both provided with rounded corner structures 118 .

[0038] According to this specific embodiment, when the seat body 112 moves, the seat body 112 drives one of the rib seats 114 to move, thereby driving the remaining rib seats 114 to move through the fabric, and the rib seat 114 drives the sliding ball 115 to slide on the slide track of the guide groove, thereby driving the outer rib 116 and the inner rib 117 to move, thereby realizing the unfolding of the fabric.

[0040] According to this specific embodiment, by providing the tension spring 119, the inner rib 117 can be made to fit the prickly ash tree as closely as possible.

[0045] When using the device for collecting and harvesting prickly ash spikes according to the present embodiment, cloth is arranged on a plurality of rib assemblies. During use, the device is first moved under the prickly ash tree where operation is required. Then, the first slide frame 103 and the second slide frame 104 are unfolded by the first handle 101 and the second handle 102, and are sleeved under the prickly ash tree. Then, the first slide frame 103 and the second slide frame 104 are closed to surround the prickly ash tree, thereby forming a full circle surrounding the root of the prickly ash tree. Then, the motor 105 is started, and the output end of the motor 105 drives the gear 106 to rotate. The gear 106 rotates on the meshing member. When the gear 106 rotates on the meshing member, it drives the slide seat to slide in the guide groove, so that the slide seat moves in a circular motion. When the slide seat moves, the cloth drives the plurality of rib assemblies to slide in the guide groove, so that the cloth arranged on the plurality of rib assemblies is unfolded to completely cover the bottom of the prickly ash tree, so that the cut ears fall into the device, forming a funnel-shaped recovery device, and then the prickly ash ear cutting operation is carried out until the operation is completed. At this time, the motor 105 is turned over to realize the folding of the cloth, and the prickly ash ears are collected in a centralized manner through the zippers of the rib assemblies in pairs, or the device is tilted manually to pour out the ears, thereby completing the operation of the prickly ash tree; then the recovery device is manually transferred to recover the ears of the next prickly ash tree, and the recovery is repeated in this way. In this way, the technical problem that the recovery of the prickly ash ears after the prickly ash ears are cut and harvested in the prior art is basically dependent on manual transportation, and during manual transportation, the epidermis of the prickly ash ears is relatively sharp and can easily pierce the skin epidermis of farmers is solved.

[0046] In the present invention, the parameter calculation and selection of the meshing member composed of the gear 106 and the semicircular gear ring are as follows:

[0047] First, the type of gear 106 is selected. The device for recovering the cut pepper ears after harvesting of the present invention does not require high speed and has a low rotation speed. Considering the convenience of installation and cost reduction, and taking into account the actual level of the current factory, a cylindrical spur gear 106 with 7-level accuracy is adopted.

[0048] Because the driving gear is a small gear 106 with a small number of teeth, the material 40Cr is selected for quenching and tempering. According to the data, the hardness of the tooth core and tooth surface is 280HBS, and the meshing material is 45 steel quenched and tempered, with a hardness of 240HB. The hardness difference between the two is 40HB. The device is expected to work for 30 days.

[0049] Select gear 106 with number of teeth Z1=18, meshing part with number of teeth Z2=130, gear ratio

[0050] Design based on tooth surface contact fatigue strength:

[0051] According to the design calculation formula of gear 106 in "Mechanical Design", the contact fatigue strength of gear 106 tooth surface is calculated as follows:

[0052]

[0053] Where d1 is the pitch circle diameter of gear 106; K is the load factor, K = K A K V K β , K A is the gear 106 service factor, K V is the load factor; T1 is the transmission torque of gear 106; σ d is the tooth width coefficient; u is the transmission ratio; Z E is the elastic coefficient of the material, Z H is the node area coefficient, Z ε is the end face overlap coefficient, [σ H ] is the allowable contact stress on the tooth surface.

[0054] Select load factor K t =1.3

[0055] Torque of gear 106:

[0056]

[0057] Substituting power P1=1.3W, n1=923RPM, we can calculate torque T1=13.45N·mm.

[0058] Look up the relevant table in "Mechanical Design" to obtain the tooth width coefficient σ d =1.

[0059] Gear 106 end face overlap:

[0060]

[0061] Calculated overlap coefficient Z ε =0.880.

[0062] Find the material elastic coefficient

[0063] Standard gear 106 takes the node area coefficient Z H =2.5.

[0064] According to the tooth surface hardness, the tooth surface contact fatigue limit σ of the active gear 106 is obtained. Hlim1 =600Mpa, contact fatigue strength limit of meshing parts σ Hlim2 =550Mpa.

[0065] Calculate the number of stress cycles according to the formula:

[0066] N = 60njLh;

[0067] Where n is the speed of the gear 106, j is the number of times the tooth surface on the same side engages when the gear 106 rotates one circle, and L h is the working life of gear 106, in h.

[0068] N1=60×923×1×30×24=3.987×10 7 ;

[0069]

[0070] So we take the contact fatigue life factor Z HN1 =0.955, Z HN2 =1.0 Safety factor is S=1,

[0071] [σ H1 ]=Z HN1 ×σ Hlim1 / S=573Mpa;

[0072] [σ H2 ]=Z HN2 ×σ Hlim2 / S=550Mpa;

[0073] Calculate the pitch circle diameter d1 and substitute [σ H ],

[0074] Substituting into formula (3-1), we get

[0075] Calculate the circumferential velocity v,

[0076] v=π×d1×n1 / (60×1000)=0.137m / s;

[0077] Tooth width b,

[0078] b=σ d d1 = 2.842 mm;

[0079] modulus m,

[0080] m=d1 / z1=0.158;

[0081] Tooth height,

[0082] h = 2.25m = 0.355mm;

[0083] so,

[0084]

[0085] According to the circumferential speed and 7-level accuracy, the dynamic load coefficient K can be obtained by looking up the table in "Mechanical Design". v =1.05, usage factor K a =1, according to the asymmetric arrangement, K hβ =1.408 So the gear 106 load factor K = 1.479, then the pitch circle diameter calculated based on the actual load factor is:

[0086]

[0087] The modulus after calibration,

[0088] m=d1 / Z1=0.165;

[0089] Design based on tooth root bending fatigue strength:

[0090]

[0091] According to the table, the bending fatigue strength limit σ of gear 106 is Fmin1 =500Mpa, bending fatigue strength limit of meshing parts σ Fmin2 =380Mpa, bending fatigue life coefficient Y NT1 =0.85, Y NT2 =0.88 Take the safety factor S F =1.4, calculate the allowable bending fatigue stress:

[0092] [σ F ]1=Y NT1 ×σ Fmin1 / S F =303.6Mpa;

[0093] [σ F ]2=Y NT2 ×σ Fmin2 / S F =238.9Mpa;

[0094] Calculate the load factor K:

[0095]

[0096] K Fβ =(K Hβ ) N =1.350;

[0097] K=K A ×K V ×K Fa ×K Fβ =1.418;

[0098] Check the tooth shape coefficient Y Fa1 =2.65,YFa2 =2.226;

[0099] Find the stress correction factor Y Sa1 =1.58,Y Sa2 =1.764;

[0100] Y ε =0.25+0.75 / ε α =0.697;

[0101] Compare:

[0102]

[0103] The size of the meshing parts:

[0104] Substitute the calculated values ​​into the formula:

[0105]

[0106] Comparing the calculation results, the modulus calculated by the tooth surface contact fatigue strength is greater than the modulus calculated by the tooth root bending fatigue strength. The bending fatigue strength mainly determines the load-bearing capacity of the gear 106, so the modulus m=0.110 calculated by the bending strength is taken, and then the nearest standard value m=0.12 is taken.

[0107] Selection of motor 105:

[0108] The resistance to the opening of the ribs of the device for recovering the cut pepper ears after harvesting is mainly the sliding friction between the slide frame and the rib seat. The resistance during recovery will be added with the load of the pepper ears, increasing the sliding friction. Because this device does not require a high speed for the opening of the ribs, it can just drive the ribs to slide, and the air resistance can be ignored, so the main resistance of the driving motor 105 is the sliding friction caused by the load of the pepper ears.

[0109] F f =μmg;

[0110] Where μ is the sliding friction coefficient, and the material selected is 6061 aluminum alloy. According to the data, the range of μ is 0.4 to 0.6. In order to consider the maximum friction, μ=0.6. The mass of the pepper spike is 5 kg, and the gravity acceleration g is 10N / S 2 , substitute into the formula and calculate:

[0111] F f = μmg = 0.6 × 5 × 10 = 30N;

[0112] The required torque is then calculated:

[0113]

[0114] N is the number of driving wheels, η is the efficiency of the motor 105, which is generally between 85% and 95%, and is taken as 90% here, i is the transmission ratio of 1, and r is the pitch circle radius of the gear 106, which is 9 mm. After substitution and calculation, the torque is obtained:

[0115] T = 0.267Nm;

[0116] The gear 106 also has its own torque from initial rest to motion, which is given by the formula:

[0117]

[0118] Calculated:

[0119] T1 = 0.01345 Nm;

[0120] The total torque is then:

[0121] T2 = T1 + T = 0.28 Nm;

[0122] After comparing the cost, performance, volume and other issues, a micro DC reduction motor 105 motor was selected. The specific address is in the cost analysis, and its parameters Figure 7 shown.

[0123] The bearing selection in the present invention is mainly to reduce friction, and the force is mainly the centripetal force when the slide moves. The movement speed of the device is relatively slow, the acceleration is small, and the force is small, so it is sufficient to meet the size requirements. According to the size of the slide frame and the slide, the bearing of the device is a plastic-coated spherical pulley 3×11×4.2mm.

[0124] After the bearing is selected, it is calibrated to ensure that the bearing meets the use requirements.

[0125] Calculate the equivalent dynamic load on the bearing:

[0126] P=XF r +YF a ;

[0127] X is the radial dynamic load coefficient, Y is the axial dynamic load coefficient. Because the bearing is installed on the slide, the bearing only bears radial load, so X=1, Y=0, and the axial load F a = 0. The radial load is obtained from the motor 105 selection F r =5N.

[0128] The bearing is subjected to less impact when the device is in operation. According to the table of "Mechanical Design", the load factor f is obtained. p The range is 1-1.2, select f p =1.2.

[0129] So when the momentum load is:

[0130] P = f p F r =1.2×5=7N;

[0131] Basic dynamic load rating:

[0132]

[0133] The bearing operating temperature is less than 120℃, and f t =1, the bearing is a roller bearing, take Bearing expected life L' h =2×180×8=2880h, substitute into the formula

[0134] We can get:

[0135]

[0136] C r >>C r1 , the bearing meets the use requirements of the recovery device.

[0137] The ribs of the umbrella of the present invention are selected because they need to store pepper spikes after being opened, so the outer ribs 116 and the inner ribs 117 need to cooperate with each other. The two ribs are tilted inwards and outwards to form a V-shaped funnel for easy recovery. The outer ribs 116 are tilted outwards toward the center of the circle, and the inner ribs 117 are tilted inwards toward the center of the circle.

[0138] Judging from the size of the existing green prickly ash tree, the overall diameter of the mechanism is not less than 3 meters, so the diameter of the outer rib 116 and the diameter of the base are added together to be not less than 3 meters. The smallest diameter of the base is 11.5 centimeters, so the radius of the ribs needs to be 138.5 cm, and the angle between the outer ribs 116 and the ground is 30 °. While facilitating the recovery of the fruit ears, the speed at which the fruit ears fall into the bottom formed between the ribs is relatively slow, protecting the prickly ash fruit ears. After simple two-dimensional geometric calculations, the length of the outer ribs 116 is not less than 160 centimeters. To ensure complete coverage, the size of the outer ribs 116 is 170 centimeters. This is designed according to the general situation of the existing green prickly ash tree, and the diameter of the specific outer ribs 116 is selected according to the general situation of the specific prickly ash producing area.

[0139] The inner rib 117 needs to take into account the lowest branch height of the prickly ash tree. Here, the distance between the lowest branch of the prickly ash tree and the ground is generally 15 cm to 30 cm. Therefore, the height of the inner rib 117 can be within 15 cm, and can be selected according to the general conditions of the prickly ash tree in the specific prickly ash producing area. When the inner rib 117 is unfolded, it is necessary to have friction with the tree. In order to reduce friction, a roller is set at the top of the inner rib 117, and the sliding friction is changed to rolling friction, which not only reduces friction, but also effectively prevents the shape of the prickly ash tree root from being too rugged, causing the inner rib 117 to tilt toward the outer rib 116.

[0140] Because the roots of the Chinese prickly ash tree are not flat, a tension spring 119 can be connected between the inner rib 117 and the outer rib 116 to prevent the inner rib 117 from being bounced open and falling outward when it is expanded and folded, thereby ensuring that the inner rib 117 always falls inward, thereby forming a storage funnel shape in cooperation with the outer rib 116.

[0141] Therefore, the force requirements of the tension spring 119 are not strict, and it only needs to be selected according to the size of the base and the umbrella base. The common cylindrical helical tension spring 119 is selected here, which has a simple structure and mature manufacturing technology and is easy to manufacture. The function of the tension spring 119 here is mainly stretching, so the specific selection is a cylindrical tensile helical tension spring 119, the tension spring 119 wire diameter d = 0.4mm, the outer diameter D2 = 3mm, and the free height H0 = 10mm. The material is stainless steel wire, the maximum axial deformation caused by work λ1 = 3mm, and the effective number of turns n = 10. The selected tension spring 119 is checked below.

[0142] The tension spring 119 works under normal load conditions. Select the Class III tension spring 119 and the Class C carbon tension spring 119 steel wire. Check σ B =1570Mpa, so [τ] = 0.8 × 0.5 × σ B =628Mpa,

[0143] Middle diameter:

[0144] D=D2-d=3mm-0.4mm=2.6mm;

[0145] Winding ratio:

[0146] C = D / d = 2.6 / 0.4 = 6.5;

[0147] Curvature coefficient:

[0148]

[0149] Calculate the maximum working load using the formula:

[0150]

[0151] The shear elastic modulus G = 82Gpa is obtained from the table, and the working load F = 4.5N is calculated;

[0152] Perform strength check on d:

[0153]

[0154] d. Meet strength standards.

[0155] Calculate the stiffness of the tension spring 119:

[0156]

[0157] Ultimate working stress:

[0158] τ lim =0.56σ B =0.56×1570=879.2Mpa;

[0159] Ultimate working load:

[0160]

[0161] The relevant calculation results of selecting the tension spring 119 all meet the working conditions.
