Description

Technical Field

[0001] The invention relates to the field of fruit picking, in particular to a fruit picking and harvesting device. Background Art

[0002] In the process of picking and harvesting pineapples, manual labor is currently more commonly used. A person needs to hold the crown of the pineapple in one hand and a knife in the other hand to cut off the stem of the pineapple to complete the harvesting and picking. However, there are many problems with this method. For example, the length of the stem of the pineapple is different, resulting in non-standard length of the fruit stalk, and the flatness of the cut pineapple stem is different, leaving sharp angles, which can easily pierce other stored peels. All of these require subsequent processing, reducing the efficiency of pineapple picking and delaying subsequent transportation. At present, there are also some pineapple picking machines, but the current pineapple picking machines are easy to crush the roots of the plants, which can easily affect the subsequent planting of pineapple plants, and cannot accurately pick pineapple fruits of different heights, which has many disadvantages.

DETAILED DESCRIPTION

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] Example 1

[0036] like Figure 1-Figure 7 As shown, the fruit picking and harvesting device includes a motor vehicle frame 1, a shock absorbing seat 2, a support beam 3, an interconnection frame 4, a fixed bracket 5, a guide frame 6, an adjustment mechanism 7, a lifting mechanism 8, a cutting mechanism 9 and a measuring mechanism 10. The motor vehicle frames 1 are in two groups, and each group of the motor vehicle frames 1 is a structure with two groups of off-road electric wheels. The shock absorbing seat 2 is fixedly connected to the upper side of the motor vehicle frame 1. The upper side of the motor vehicle frame 1 is provided with a support beam 3, and the support beam 3 is a transverse frame structure. The interconnection frame 4 is fixedly connected between the support beams 3 on both sides, and the interconnection frame 4 is a U-shaped structure. The interconnecting frame 4 is used to fix the support beams 3 and their accessories on both sides. The upper side of the interconnecting frame 4 is fixedly connected with a fixed bracket 5. The front side of the fixed bracket 5 is fixedly connected with a guide frame 6. The two groups of guide frames 6 form a Y-shaped structure extending to the front side. The Y-shaped structure formed by the guide frames 6 on both sides is used to relatively guide the pineapple on the front side to enter the middle position of the fixed bracket 5. The motor vehicle frame 1, the support beam 3, the interconnecting frame 4 and the guide frame 6 form a door-type structure in the front and rear directions, which can improve the passability of the fruit picking and harvesting device and can The guide frame 6 can pass through the strip-shaped pineapple planting area in a leaping manner, and can protect the roots of the pineapples when they are planted next time. An adjusting mechanism 7 is provided between the shock-absorbing seat 2 and the adjacent support beams 3. The adjusting mechanism 7 is used to adjust the height of the support beams 3 on both sides from the ground to adjust the height of the guide frame 6 relative to the pineapple, so that the guide frame 6 is adjusted to be located on the same horizontal line as the stem of the pineapple plant and the pineapple fruit. The height of the guide frame 6 is lower than that of the pineapple, which can be suitable for pineapple fruits of uneven heights. A lifting mechanism 8 is provided on the upper side of the interconnection frame 4, and the lifting mechanism 8 is used to The lifting mechanism 8 is provided with a cutting mechanism 9 and a measuring mechanism 10. The cutting mechanism 9 is used to cut the stem of the pineapple plant to separate the pineapple fruit from the plant. The measuring mechanism 10 is used to straighten the pineapple fruit and measure whether the pineapple fruit is at a suitable cutting height. The spacing between the cutting mechanism 9 and the measuring mechanism 10 is 2 cm, which is the appropriate length of the pineapple stalk. The measuring mechanism 10 can straighten the pineapple fruit after being lifted by the lifting mechanism 8, and make the pineapple fruit at a suitable stem cutting length by measuring, so as to retain a pineapple stalk of a suitable length.

[0037] When harvesting pineapples in a pineapple plantation, the fruit picking and harvesting device can be used to ensure the flatness and straightness of the pineapple fruit incision, to make the pineapple incision have a suitable stem length, and to avoid sharp corners that damage the skin of other pineapples, thereby improving the safety of pineapple transportation; the fruit picking and harvesting device can be transferred to the pineapple plantation through a motor vehicle frame 1, and the fruit picking and harvesting device can be placed across a strip-shaped pineapple planting area in a door-like layout structure, and then the adjustment mechanism 7 on both sides is operated to make the adjustment mechanism 7 drive the support beams 3 on both sides to move, so that the guide frame 6 can be under the fruits of the pineapple planting area of ​​this strip. The measuring mechanism 10 is then turned on to put the measuring mechanism 10 in the on state; thereafter, the motor vehicle frame 1 can be controlled to move slowly forward, and when the guide frame 6 moves forward to the rear of a pineapple, the pineapple will be guided by the guide frame 6 and relatively moved to the position between the interconnected frames 4. When the pineapple moves relatively to the top of the measuring mechanism 10, the stem of the pineapple will be within the cutting range of the cutting mechanism 9. At this time, the lifting mechanism 8 can be controlled to operate, and the lifting mechanism 8 will drive the measuring mechanism 10 and the cutting mechanism 9 to move upward until the measuring mechanism 10 When the bottom of the pineapple is touched, the measuring mechanism 10 moves upward to touch the pressure value of the bottom of the pineapple as an identification signal. At this time, the bottom of the pineapple is kept 2 cm away from the cutting mechanism 9, which is the appropriate length of the pineapple stalk. At this time, the pineapple is lifted by the measuring mechanism 10, and the pineapple is also straightened by the measuring mechanism 10. The stem of the pineapple is also straightened. At this time, the measuring mechanism 10 will control the lifting mechanism 8 to stop the rising operation through the program, and control the cutting mechanism 9 to operate, so that the cutting mechanism 9 cuts the stem of the pineapple. At this time, the pineapple fruit is separated from its stem, and because the pineapple is lifted by the measuring mechanism 10, the pineapple is straightened by the measuring mechanism 10. 0, so that the cut at the pineapple stalk is smooth and has no sharp corners, and the stalk will not pierce the peel of other pineapples when the pineapple is transported. Because the bottom of the pineapple is limited by the position of the measuring mechanism 10, the pineapple stalk can also keep a standard 2 cm stalk after being cut by the cutting mechanism 9; after the pineapple is cut, the pineapple can be taken down and gently placed in an external collection device, and the cutting mechanism 9 will automatically reset to prepare for cutting the next pineapple, and control the lifting mechanism 8 to move downward for reset, thereby driving the measuring mechanism 10 and the cutting mechanism 9 to reset, so as to perform the above steps on the next pineapple.

[0038] By adopting the motor vehicle frame, the support beam, the interconnecting frame and the guide frame to form a door-type structure in the front-rear direction, the passability of the fruit picking and harvesting device can be improved, and the device can pass through the strip-shaped pineapple planting area in a leaping manner, thereby protecting the roots of the pineapple plants when the pineapple is planted next time.

[0039] Example 2

[0040] like Figure 2 As shown, the adjustment mechanism 7 includes a telescopic sleeve 71, an adjustment frame 72 and a screw pair 73. The number of the telescopic sleeves 71 is two groups. The telescopic sleeves 71 are respectively fixedly connected to the base of each of the shock absorber seats 2. The telescopic sleeves 71 are vertically arranged. The telescopic sleeves 71 are structures with telescopic tubes. The upper ends of the telescopic tubes of each group of the telescopic sleeves 71 are fixedly connected to the adjustment frames 72. The adjustment frames 72 are respectively fixedly connected to the adjacent support beams 3. The upper sides of the bases of the shock absorber seats 2 are rotatably connected to the screw pairs 73. The screw pairs 73 are structures with nut moving parts and crank handles. The nut moving parts of the screw pairs 73 are respectively fixedly connected to the adjacent adjustment frames 72.

[0041] By rotating the screw pair 73 on both sides, the screw pair 73 will drive its nut moving part to move up and down, so that the nut moving part of the screw pair 73 drives the adjustment frame 72 to move up and down through the telescopic sleeve 71, thereby driving the support beam 3 and the guide frame 6 to move up and down.

[0042] like Figure 8-Figure 9 As shown, the lifting mechanism 8 includes an electric slide rail 81, a displacement frame 82 and a lifting bracket 83. The electric slide rail 81 is in two groups and is vertically arranged. The electric slide rails 81 are respectively fixedly connected to the two side walls at the upper rear position of the interconnection frame 4. The moving parts of the electric slide rail 81 are fixedly connected to the displacement frame 82. The front side of the displacement frame 82 is fixedly connected to the lifting bracket 83. The measuring mechanism 10 is connected to the upper side of the lifting bracket 83, and the cutting mechanism 9 is connected to the lower side of the lifting bracket 83.

[0043] When a pineapple fruit moves relatively to the position between the interconnected frames 4 and is located between the lifting brackets 83, the pineapple is now located between the measuring mechanisms 10 and the cutting range of the cutting mechanism 9; at this time, the electric slide rails 81 on both sides can be controlled to move upward, so that the electric slide rails 81 drive the displacement frame 82 and the lifting bracket 83 to move upward, and the lifting bracket 83 drives the measuring mechanism 10 and the cutting mechanism 9 to move upward, and the measuring mechanism 10 will detect the contact pressure with the pineapple. When the measuring mechanism 10 detects that the contact pressure reaches the set value, the measuring mechanism 10 will control the electric slide rail 81 to stop running. At this time, the measuring mechanism 10 will control the cutting mechanism 9 to cut the stem of the pineapple, thereby completing the separation of the pineapple fruit and the stem; thereafter, the electric slide rail 81 can be controlled to move downward for resetting.

[0044] like Figure 11-Figure 14As shown, the cutting mechanism 9 includes a protective box 91, a guide rail 92, a push plate 93, an electric push rod 94, a triangular blade 95 and a matching blade 96. There are two protective boxes 91, and the protective boxes 91 are symmetrically fixedly connected to the lower side of each fixed bracket 5. The front and rear side walls inside the protective box 91 are fixedly connected with guide rails 92, and the guide rails 92 are horizontally arranged. The guide rails 92 are detachable as guide block moving parts. Push plates 93 are fixedly connected between the guide rails 92. The lower side of the protective box 91 is fixedly connected with electric push rods 94, and the electric push rods 94 are horizontally arranged. The electric push rods 94 on both sides are opposite to each other. The pusher plate 93 is arranged in a balanced manner, and the moving parts of each group of the electric push rods 94 are respectively connected to the adjacent pusher plates 93. The inner side of the pusher plate 93 on the left side is detachably connected with a triangular blade 95, and the triangular blade 95 is a triangular structure, and the triangular blade 95 is arranged with the top angle facing inward, and the triangular blade 95 is a structure with two beveled edges partially sharpened. The inner side of the pusher plate 93 on the right side is detachably connected with a mating blade 96, and the mating blade 96 is a concave structure mating with the triangular blade 95, and the mating blade 96 is arranged with two top angles facing inward, and the mating blade 96 is a structure with two beveled edges partially sharpened inwardly, and the triangular blade 95 and the mating blade 96 can contact and cooperate.

[0045] After the cutting mechanism 9 is controlled and started, the electric push rod 94 will perform a cycle of operation. The electric push rod 94 will first drive its moving parts to move inward at the same time, thereby driving the push plate 93 to move inward through the guide track 92, and the push plate 93 will respectively drive the triangular blade 95 and the matching blade 96 connected thereto to move inward, and the matching blade 96 will fine-tune the position of the pineapple stem through its concave structure, and make the pineapple stem in the concave of the matching blade 96 to avoid the slipping of the knife during cutting. The triangular blade 95 and the matching blade 96 will cut the pineapple stem to separate the pineapple fruit from its stem because the pineapple is straightened by the measuring mechanism 10; compared with the traditional pineapple cutting method, that is, using a tool to directly cut off its stem will make the stem uneven and leave a pointed fruit handle, moving the triangular blade 95 and the matching blade 96 in both directions at the same time will achieve the purpose of cutting the pineapple stem straight, and at the same time, personnel do not use tools to ensure personnel safety.

[0046] By using the triangular blade and the matching blade of the cutting device to cooperate in cutting the pineapple stem, the matching blade can finely adjust the position of the pineapple stem through its concave structure, and the pineapple stem is placed in the concave of the matching blade, thereby avoiding the knife slipping phenomenon during cutting. Compared with the traditional pineapple cutting method, that is, using a knife to directly cut the stem, which will make the stem uneven and leave a pointed fruit stalk, the triangular blade and the matching blade can be moved in both directions at the same time to achieve the purpose of cutting the pineapple stem straight, and at the same time, personnel do not need to use a knife, thereby ensuring personnel safety.

[0047] like Figure 8-Figure 10 As shown, the measuring mechanism 10 includes a pressure sensor 101 and a measuring bracket 102. There are two pressure sensors 101. The pressure sensors 101 are respectively fixedly connected to the upper side of the lifting bracket 83. The pressure sensor 101 is vertically arranged. The pressure sensor 101 is used to detect the vertical pressure. The upper side of the pressure sensor 101 is fixedly connected with a measuring bracket 102, and the measuring bracket 102 is used to hold the pineapple fruit.

[0048] When the pineapple is located between the interconnected frames 4, the pineapple will also be located between the measuring brackets 102. At this time, the lifting mechanism 8 is controlled to move upward, and the lifting bracket 83 will drive the pressure sensor 101 and the measuring bracket 102 to move upward. When the measuring bracket 102 begins to contact the bottom of the pineapple, the pressure sensor 101 will detect the pressure from the relative movement of the pineapple, and the measuring bracket 102 will also contact and straighten the pineapple during the upward movement, and the stem of the pineapple will be straightened. When the value of the pressure sensor 101 reaches the set value, the pressure sensor 101 will control the electric slide rail 81 to stop moving upward through a program, and the pressure sensor 101 will control the cutting mechanism 9 to operate at the same time, so that the cutting mechanism 9 cuts the stem of the pineapple; and the set pressure detected by the pressure sensor 101 for the relative movement of the pineapple can be based on the fact that the bottom flesh is not damaged when the measuring bracket 102 moves upward to straighten the pineapple and straighten the stem, and pineapples of different maturity have different destruction pressure thresholds, and the set pressure data can be lower than the destruction pressure thresholds of pineapples of different maturity.

[0049] By using the measuring mechanism to receive the pressure of the pineapple to measure its appropriate cutting length, the pineapple can be straightened, so that the incision at the pineapple stem can be smooth and without sharp corners after cutting, and the stem will not pierce the peels of other pineapples when the pineapple is transported. Because the bottom of the pineapple is limited by the position of the measuring mechanism, the pineapple stem can also retain a standard stem of 2 cm after being cut by the cutting mechanism. In addition, by driving the measuring mechanism to rise and contact the bottom of the pineapple through the lifting mechanism, pineapples of different heights can still retain stems of equal length after cutting.

[0050] Example 3

[0051] like Fig.16 As shown, a detection mechanism 11 is also included, and the detection mechanism 11 includes a laser transmitter 111 and a laser receiver 112. The detection mechanism 11 is arranged at a position below the cutting mechanism 9 on the fixed bracket 5. The detection mechanism 11 is used to automatically detect that the pineapple fruit is located between the cutting mechanism 9 and the measuring mechanism 10. The laser transmitter 111 is fixedly connected to the lower right side of the fixed bracket 5, and the laser receiver 112 is fixedly connected to the lower left side of the fixed bracket 5. The laser transmitter 111 and the laser receiver 112 are in corresponding positions, and the laser transmitter 111 and the laser receiver 112 constitute an identification mechanism.

[0052] After the laser transmitter 111 and the laser receiver 112 are turned on, the laser transmitter 111 will emit a laser which will be received by the laser receiver 112. At this time, the laser receiver 112 does not output a control signal for identifying the pineapple. When the pineapple moves relatively to the position between the cutting mechanism 9 and the measuring mechanism 10, the stem of the pineapple will block the laser emitted by the laser transmitter 111. At this time, the laser receiver 112 will output a control signal for identifying the pineapple if it does not receive the laser. At this time, the lifting mechanism 8 will be controlled to operate, that is, the operating procedures of the lifting mechanism 8, the measuring mechanism 10 and the cutting mechanism 9 as described above will be started. After the execution of this operating procedure is completed, the laser receiver 112 will re-enter the identification procedure. At this time, as the motor vehicle frame 1 moves slowly, the stem of the pineapple is away from the laser emission range of the laser transmitter 111. In this way, the cooperation and signal output of the laser transmitter 111 and the laser receiver 112 can be used as a switch for cutting and picking the pineapple as a whole after it is in place, which can improve the accuracy of pineapple cutting identification and cutting and picking, reduce the error rate, and improve the degree of automation.

[0053] like Fig.15As shown, it also includes a collecting mechanism 12, which includes a side plate 121, a blocking plate 122, a traction rib 123 and a collecting cloth block 124. The collecting mechanism 12 is respectively arranged at the position of the support beam 3. The collecting mechanism 12 is used to quickly collect the pineapples after cutting and picking. The front and rear sides of the support beam 3 are fixedly connected with the side plates 121, and the side plates 121 are all made of rubber. The outer sides of each two groups of opposite side plates 121 are fixedly connected with blocking plates 122, and the blocking plates 122 are all structures with openings on the upper sides. The blocking plates 122 are all made of rubber. The blocking plates 122 and the lower sides of the blocking plates 122 and the side plates 121 are both distributed with traction ribs 123 in an array, and the traction ribs 123 are rubber ribs made of rubber material. The lower sides of the traction ribs 123 are hoisted with collecting cloth blocks 124, and the collecting cloth blocks 124 are made of soft rubber material.

[0054] According to the pressure detection value of the pressure sensor 101, a program can be set to control the relative operation of the two groups of the electric slide rails 81. After the pineapple is cut on the measuring bracket 102, the pineapple fruit is placed on the measuring bracket 102 and the pressure sensor 101 without load. At this time, the pressure sensor 101 can measure the quality of the pineapple fruit, divide the pineapple quality into two grades, and grade the quality of the two grades. The graded quality values ​​are entered into the program to control the relative operation of the two groups of the electric slide rails 81; when the pressure sensor 101 detects that a cut pineapple is below the set graded quality value, the pressure sensor 101 will control the two groups of the electric slide rails 81. The two sets of electric slide rails 81 run in opposite directions to each other, so that the measuring brackets 102 run up and down, and the pineapple on the measuring bracket 102 falls down because one side cannot be supported. Similarly, if a cut pineapple is above the set grading value, the pressure sensor 101 will control the two sets of electric slide rails 81 to run in opposite directions to each other, so that the pineapple on the measuring bracket 102 falls down because the other side cannot be supported. In this way, the pineapple can be graded by quality; and the fallen pineapple will fall on the collecting cloth block 124. The elasticity of the material of the collecting cloth block 124 itself and the elasticity of the traction ribs 123 will protect the pineapple from being damaged. At this time, the pineapple can be picked up and loaded into different collecting devices to complete the preliminary grading.

[0055] like Figure 1 As shown, a display component 13 is also included. The display component 13 is fixedly installed on the rear side of the interconnection frame 4. The display component 13 is a display. The display content of the display component 13 is the pressure value of the pressure sensor 101.

[0056] The display assembly 13 can display the pressure value of the pressure sensor 101, and personnel can accurately classify the quality of each pineapple according to the pressure value and place the pineapples in different collecting containers.

[0057] Through the cooperation of the adjusting mechanism, the lifting mechanism, the cutting mechanism, the measuring mechanism, and the detecting mechanism, the degree of automation in the pineapple picking process can be improved, pineapples of different heights can be picked accurately, and the cutting and picking of the pineapples can retain the standard length of the stalks, ensuring that the pineapple cut surface is flat and straight without sharp corners, and will not damage other stored pineapple peels.
