[0035] According to this specific embodiment, when the motor 105 drives the gear 106 to rotate, due to the fixedness of the engaging 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 several of the bearings 113 to slide in the guide groove.

[0036] At the same time, 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. The outer umbrella rib 116 and the inner umbrella rib 117 are both on the umbrella rib seat 114.

[0037] The inner ribs 117 and the outer ribs 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 umbrella rib seats 114 to move, thereby driving the remaining umbrella rib seats 114 to move through the fabric, and the umbrella rib seat 114 drives the sliding ball 115 to slide on the slide track of the guide groove, thereby driving the outer umbrella rib 116 and the inner umbrella rib 117 to move, thereby realizing the unfolding of the fabric.

[0045] When using the device for collecting and harvesting prickly ash spikes after cutting according to the present embodiment, cloth is provided on a plurality of rib assemblies. During use, the device is first moved under the prickly ash tree where operation is required, and 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 placed under the prickly ash tree. Subsequently, 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, and then the motor 105 is started, and the output end of the motor 105 drives the gear 106 to rotate, and the gear 106 rotates on the meshing member, and when the gear 106 rotates on the meshing member, it drives the slide to slide in the guide groove, so that the slide moves in a circular motion, and the When the slide seat moves, the cloth drives the plurality of rib assemblies to slide in the guide groove through the cloth, so that the cloth set on the plurality of rib assemblies is unfolded to completely cover the bottom of the prickly ash tree, so that the cut fruit ears all 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, the motor 105 is flipped to realize the folding of the cloth, and the prickly ash fruit ears are collected in a centralized manner through the zippers of the two rib assemblies, or the device is tilted manually to pour out the fruit ears, thereby completing the operation of the prickly ash tree; then the recovery device is manually transferred to recover the fruit ears of the next prickly ash tree, and the recovery is repeated in this way. In this way, the technical problem that the fruit ear recovery after the prickly ash ear cutting and harvesting in the prior art basically relies on manual transportation, and during manual transportation, the skin of the prickly ash fruit ears is relatively sharp and can easily pierce the skin 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 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 precision is adopted.

[0048] Because the driving gear is a small 106-inch gear with a small number of teeth, 40Cr was selected for quenching and tempering. According to research, the hardness of the tooth core and tooth surface is 280HBS. The meshing material is 45 steel, which has been quenched and tempered and has a hardness of 240HB, a difference of 40HB. The device is expected to operate for 30 days.

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

[0050] Designed 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 service factor of gear 106, 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 coincidence 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 = 1.3 W and n1 = 923 RPM, we can calculate torque T1 = 13.45 N·mm.

[0058] Check the relevant table of "Mechanical Design" to get the tooth width coefficient σ d =1.

[0059] Gear 106 end face contact:

[0060]

[0061] Calculated coincidence 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 σ of meshing parts Hlim2 =550Mpa.

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

[0066] N=60njL h ;

[0067] Where n is the speed of gear 106, j is the number of times the same side tooth surface engages when gear 106 rotates one circle, 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 coefficient 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 peripheral 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 coefficient K a =1, according to the asymmetric arrangement, K hβ =1.408 So the load factor K of gear 106 is 1.479. Then the pitch circle diameter calculated according to the actual load factor is:

[0086]

[0087] The modulus after calibration,

[0088] m=d1 / Z1=0.165;

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

[0090]

[0091] According to the table, the bending fatigue strength limit σ of gear 106 is obtained Fmin1 =500Mpa, bending fatigue strength limit σ of the meshing parts 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] Check the stress correction coefficient 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 from the tooth surface contact fatigue strength is greater than the modulus calculated from the tooth root bending fatigue strength. The bending fatigue strength mainly determines the load-bearing capacity of the gear 106, so the modulus m calculated from the bending strength is taken as 0.110, and then the nearest standard value m=0.12 is taken.

[0107] Selection of motor 105:

[0108] The resistance to opening the ribs of the post-harvest Sichuan peppercorn recovery device is primarily due to the sliding friction between the slide frame and the rib holder. The resistance during recovery is compounded by the load of the Sichuan peppercorns, further increasing the sliding friction. Because this device does not require high rib opening speed, simply sliding the ribs is sufficient, and air resistance is negligible, the primary resistance to the motor 105 is the sliding friction caused by the load of the Sichuan peppercorns.

[0109] F f =μmg;

[0110] Where μ is the coefficient of sliding friction. The material used is 6061 aluminum alloy. According to the literature, μ ranges from 0.4 to 0.6. To consider the maximum friction, μ is set to 0.6. The mass of the pepper ear is 5 kg, and the acceleration due to gravity g is 10 N / S. 2 , substitute into the formula to 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 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 gear 106, which is 9mm. Substituting the values, the torque is calculated as:

[0115] T = 0.267 Nm;

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

[0117]

[0118] Calculated:

[0119] T1=0.01345Nm;

[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 bearings used in this utility model primarily serve to reduce friction, and are primarily subjected to the centripetal force of the slide's movement. Since the device's deployment speed is relatively slow, with low acceleration and low force, meeting the dimensional requirements is sufficient. Based on the dimensions of the slide frame and slide, the bearings used in this device are plastic-coated spherical pulleys measuring 3×11×4.2mm.

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

[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. Since the bearing is installed on the slide, the bearing only bears radial load, then X=1, Y=0, and the axial load F a = 0. The radial load is obtained by selecting the motor 105 F r =5N.

[0128] The bearings are subjected to less impact when the device is in operation. The load factor f is obtained from the table in Mechanical Design. 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 operating temperature of the bearing is less than 120℃, and the table shows 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 the pepper ears after being opened, so the outer ribs 116 and the inner ribs 117 need to cooperate with each other. The two ribs are tilted inward and outward to form a V-shaped funnel for easy recovery. The outer ribs 116 are tilted outward toward the center of the circle, and the inner ribs 117 are tilted inward toward the center of the circle.

[0138] Judging from the size of existing green prickly ash trees, the overall diameter of the mechanism should be no less than 3 meters. Therefore, the diameter of the outer ribs 116 expanded and the diameter of the base added together should be no less than 3 meters. The minimum base diameter 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 degrees. This facilitates the recovery of the fruit ears and also slows the speed at which the fruit ears fall into the bottom formed between the ribs, thus protecting the prickly ash ears. A simple two-dimensional geometric calculation shows that the length of the outer ribs 116 is no less than 160 centimeters. To ensure complete coverage, the size of the outer ribs 116 is designed to be 170 centimeters. This is designed based on the general conditions of existing green prickly ash trees, and the diameter of the specific outer ribs 116 is selected according to the general conditions of the specific prickly ash producing area.

[0139] The height of the inner ribs 117 must be considered to meet the lowest branch height of the Sichuan pepper tree. Here, the lowest branch height is typically 15 to 30 centimeters from the ground. Therefore, the height of the inner ribs 117 can be within 15 centimeters and can be selected based on the typical conditions of Sichuan pepper trees in a specific Sichuan pepper producing area. When deployed, the inner ribs 117 require friction with the tree. To reduce friction, rollers are installed at the tops of the inner ribs 117, switching from sliding friction to rolling friction. This not only reduces friction but also effectively prevents the uneven shape of the Sichuan pepper tree's roots from causing the inner ribs 117 to tilt toward the outer ribs 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 ensure that the inner rib 117 will not be bounced open and fall outward when it is expanded and folded, ensuring that the inner rib 117 always falls inward, thereby forming a storage funnel shape with the outer rib 116.

[0141] Therefore, the force requirements for tension spring 119 are not stringent; the selection only needs to be based on the dimensions of the base and the umbrella base. A common cylindrical helical tension spring 119 is used here, which has a simple structure and is readily manufactured using mature manufacturing technology. The primary function of tension spring 119 here is tension, so a cylindrical helical tension spring 119 is specifically selected. The wire diameter d = 0.4 mm, the outer diameter D2 = 3 mm, and the free height H0 = 10 mm are selected. The material is stainless steel wire, the maximum axial deformation caused by operation = 3 mm, and the number of effective coils n = 10. The selected tension spring 119 is verified below.

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

[0143] Medium 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 the strength standards.

[0155] Calculate the stiffness of 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.
