Technical Field

[0001] The invention relates to the technical field of experimental models, in particular to a pineapple single plant entity model that can be circulated, split and reused. Background Art

[0002] Pineapple has a long growth cycle and the field environment is harsh and complex. It is mainly planted in Zhanjiang, the southernmost part of Guangdong Province in my country. So far, the harvesting equipment for pineapple fields at home and abroad has been in a state of "no machine available". Some high-efficiency, scientific research institutes and enterprises have successively developed some prototypes and harvesting devices. However, due to the long distance from the test site, it is not convenient to carry out field tests, resulting in a low frequency of technical design and improvement work, slowing down the development progress of special harvesting equipment and lengthening the development cycle. At present, the invention of test models for pineapples or other stems is still in a blank stage. Most models are only for viewing and exhibition, and do not have the test value of physical contact and interaction with machines. Summary of the invention

[0003] The purpose of the present invention is to provide a pineapple single plant entity model that can be recycled, disassembled and reused, which realizes high-quality simulation of field pineapple plants in terms of structural shape, material properties and connection methods, and provides important conditions and test objects for the design, development and testing of special picking and harvesting equipment.

[0004] In order to solve the above technical problems, the present invention provides a pineapple single plant entity model that can be recycled, split and reused, comprising:

[0005] fruit;

[0006] A stem-fruit connecting stalk, one end of which is connected to the fruit;

[0007] A variable cross-section stem, the variable cross-section stem is connected to the other end of the stem-fruit connecting stalk; a filling groove is arranged inside the variable cross-section stem along its long axis, and the filling groove extends to the inside of the stem-fruit connecting stalk;

[0008] A strengthening inner core, the strengthening inner core is inserted into the filling groove;

[0017] Beneficial effects:

[0018] The present invention arranges fruits, stem-fruit connecting stalks and variable-section stalks that are connected in sequence, which are highly consistent with the structural dimensions and important physical properties of actual pineapple plants in the field.

[0036] See also Figure 1-8, a preferred embodiment of the present invention provides a pineapple single plant physical model that can be recycled, disassembled and reused, including a fruit 1, a stem-fruit connecting stalk 2, a variable-section stem 3, a reinforced inner core 4 and a base plug 5, one end of the stem-fruit connecting stalk 2 is connected to the fruit 1; the variable-section stem 3 is connected to the other end of the stem-fruit connecting stalk 2; the interior of the variable-section stem 3 is provided with a filling groove 31 along its long axis, and the filling groove 31 extends to the interior of the stem-fruit connecting stalk 2; the reinforced inner core 4 is inserted in the filling groove 31; the base plug 5 is inserted in the filling groove 31 at one end away from the stem-fruit connecting stalk 2.

[0037] In some preferred embodiments of the present invention, the fruit 1 is provided with a conical annular boss structure 11 , and one end of the stem-fruit connecting stalk 2 is provided with a conical tube structure 21 that cooperates with the conical annular boss structure 11 .

[0038] In some preferred embodiments of the present invention, a plurality of openings 22 are formed on the peripheral wall of the conical tube structure 21 , and a plurality of rows of inclined annular grooves 25 are formed on the inner wall surface of the conical tube structure 21 .

[0039] In some preferred embodiments of the present invention, a cylindrical tubular structure 24 is provided at the other end of the stem-fruit connecting stalk 2 , and an annular groove 25 is provided on the inner wall surface of the cylindrical tubular structure 24 .

[0040] In some preferred embodiments of the present invention, one end of the variable-section stem 3 is provided with an annular flange structure 32 that cooperates with the cylindrical tubular structure 24 .

[0041] In some preferred embodiments of the present invention, the filling groove 31 is a cylindrical or polygonal hole.

[0042] In some preferred embodiments of the present invention, the radius of one end of the variable-section stalk 3 away from the stem-fruit connecting stalk 2 is larger than the radius of the other end.

[0043] It should be noted that, in order to ensure accurate use value and application significance, the present invention measured the dimensions of actual pineapple plants and fruits 1 in the field, carried out tests on fruit-stem fracture mechanics and resolution conditions, and finally obtained important physical property parameters. Therefore, the present invention further limits the specific protection scope of the main materials and dimensional parameters, specifically: the above-mentioned whole is all soft and elastic material (such as rubber, silicone, polyurethane rubber, etc.); the mass mF of the fruit 1 is limited to 1.2-2.2kg, the material density F is in the range of about 1.0-1.15g / cm3, and the maximum diameter range DFmax of the fruit 1 is 100- 150mm, the height hF of the fruit 1 ranges from 125 to 165mm, the height hFS of the conical annular boss at the bottom of the fruit 1 ranges from 20 to 50mm; the diameter DS of the fruit-near-fruit area at the upper end of the stem ranges from 22 to 35mm, and the height HS of the stem ranges from 330 to 520mm; the length LFS of the stem-fruit connecting stalk ranges from 80 to 150mm; the material of the reinforced inner core 4 is generally elastic steel wire, and the diameter ranges from 1.0 to 3.5mm; the conical annular boss at the lower end of the fruit 1 of the model and the inclined annular groove 25 at the upper end of the stem-fruit connecting stalk, when bent and disengaged by external force in a buckled fixed state, the maximum torque required does not exceed 5Nm.

[0044] When it is necessary to restore the complete plant form of the field pineapple, the installation operation process is as follows: first, install from bottom to top, first insert the base plug 5 into the corresponding hole at the bottom of the variable cross-section stem 3 and fix it, and then selectively insert the strengthening inner core 4 according to the bending resistance requirements of the stem to be tested. In this link, in the invention, Figure 2 As shown, 5 filling slots 31 are provided, but the present invention does not limit the number. If the bending resistance requirement of the stem is large, a reinforced inner core 4 with a larger cross-sectional diameter can be selected, or a larger number of filling slots 31 can be provided, which can improve the bending resistance of the variable cross-section stem 3. The physical properties of the stems of different pineapple varieties are different, that is, the elastic modulus is different. In implementation, the number and thickness can be adjusted according to actual needs. After the reinforced inner core 4 is fixed, the stem-fruit connection stalk and the upper end cylinder of the variable cross-section stem 3 are kept in the same axis direction, and the filling slot 31 hole inside the stem-fruit connection is aligned with the reinforced inner core 4 fixed on the variable cross-section stem 3, and the two are buckled and fixed by external force pressing. Finally, the conical annular boss at the lower end of the fruit 1 is coaxially aligned with the inclined annular groove 23 at the upper end of the stem-fruit connection stalk, and pressed / or screwed in by external force. At this point, the installation of the overall model is completed.

[0045] It is important to note that, based on the agronomic requirements for pineapple planting and harvesting, and with reference to relevant key technologies for picking and harvesting, the best way to separate pineapple fruit 1 is to "break and snap," i.e., press, bend, and break. Figure 8As shown, when it is necessary to conduct a fruit 1 picking / harvesting test, the connection method between the fruit 1 and the upper end of the stem-fruit connecting stalk of the present invention is designed for the actual plant growth morphology and physical characteristics. Therefore, it is only necessary to grasp or clamp the upper end of the fruit 1, and further overcome the several openings 22 features at the upper end of the stem-fruit connecting stalk by pressing, bending or twisting, and then make the conical annular boss at the lower end of the fruit 1 and the inclined annular groove 23 at the upper end of the stem-fruit connecting stalk slide and disengage, and finally achieve the separation of the fruit 1 from the stem. Finally, it should be noted that according to field test tests, the maximum torque required for the pineapple to bend and break from the stem to separate does not exceed 4.4Nm. The present invention has verified its effectiveness by developing a real object, and further defines that the maximum torque for the bending and separation of the fruit 1 and the stem of this model does not exceed 5Nm.

[0046] The preferred embodiment of the present invention provides a pineapple single plant entity model that can be recycled, split and reused. Compared with the prior art,

[0047] The present invention arranges fruits 1, stem-fruit connecting stalks 2 and variable-section stalks 3 that are connected in sequence, which are highly consistent with the structural dimensions and important physical properties of actual pineapple plants in the field. The connection form and separation method between the fruit 1 and the stalks almost restore the composition structure of real crops; and the pineapple plant monomer is modularly split into three major parts, namely the stalk, the connecting stalk and the fruit 1. Among them, the multiple filling grooves 31 arranged inside the stem have good reconstructability and adjustment characteristics, and can simulate stems of multiple varieties and different strength differences; in addition, the installation is simple during implementation, and any module component can be reset and replaced, which is convenient for operation and maintenance.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
