Description

Technical Field

[0002] In the process of plant sowing and seedling raising, in order to improve the germination efficiency of seeds, especially for hard seeds, some tools are often used to break the seed coat. Since the seed coat of hard seeds is hard and dense with poor water permeability, the normal germination process of the seeds is affected. Breaking the seed coat can increase the seed's absorption of water and oxygen, which is beneficial to seed germination.

[0003] The most commonly used method of breaking the seed coat is to drill holes in the seed coat to allow water and air to enter the seed. However, due to the different seed coat thicknesses of seeds of different species, it is difficult to control the depth of the seed coat when drilling holes. Deep drilling can easily break the seeds, causing damage to the seed structure, poor seed growth or loss of activity. Shallow drilling does not completely destroy the seed coat, making it difficult for the seeds to absorb water, which in turn affects the germination efficiency of the seeds. Summary of the invention

[0042] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs.

For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0044] In the relevant technology, in order to improve the germination efficiency of seeds, especially for hard seeds, some tools are often used to break the seed coat. Since the seed coat of hard seeds is hard and dense with poor water permeability, the normal growth of seeds is affected. Breaking the seed coat can improve the seed's absorption of water and oxygen, which is beneficial to seed germination.

[0045] Currently, the more commonly used method of breaking the seed coat is to drill holes in the seed coat to allow water and air to enter the seed. However, since the seed coats of seeds of different species are of different thicknesses, it is difficult to control the depth of the seeds when drilling holes. Deep drilling can easily break the seeds, causing damage to the seed structure, poor seed growth or loss of activity. Shallow drilling can prevent the seed coat from being completely destroyed, making it difficult for the seeds to absorb water, which in turn affects the germination efficiency of the seeds.

[0046] Based on this, the present application provides a device for breaking the seed coat of hard seeds, including a seed placement plate, a bracket and a needle piercing assembly, and the needle piercing assembly includes a needle placement bed, an adjustment plate, a telescopic member group and a fixing member. The telescopic member group is used to adjust the distance between the needle placement bed and the adjustment plate, and the fixing member is arranged on the telescopic member group, and is used to fix the relative position of the needle placement bed and the adjustment plate. During use, by adjusting the distance between the needle placement bed and the adjustment plate, the length of the puncture needle passing through the adjustment plate is controlled to be the same as the thickness of the seed coat, and the fixing member is used to fix the relative position between the adjustment plate and the seed placement plate, and then the needle piercing assembly is slid on the bracket so that the adjustment plate contacts the seeds in the placement groove, and the puncture needle can accurately pierce the seed coat of the seed without damaging the seed, thereby improving the germination efficiency of the seed.

[0047] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0048] Reference Figure 1 and Figure 2 The embodiment of the present application provides a device for breaking the seed coat of hard seeds, including: a seed placement plate 100, a bracket 200, and a needle threading assembly 300. The seed placement plate 100 is provided with a plurality of placement grooves 110 for accommodating seeds.

[0049] The needle threading assembly 300 is arranged above the seed placement plate 100. The needle threading assembly 300 includes a needle placement bed 310, an adjustment plate 320, a telescopic member group 330 and a fixing member 340. The needle placement bed 310 and the adjustment plate 320 are both slidably arranged on the bracket 200. A plurality of puncture needles 311 are arranged on the needle placement bed 310. A plurality of needle holes for the puncture needles 311 to pass through are opened on the adjustment plate 320. The puncture needles 311 correspond to the placement slots 110.

[0050] The telescopic member group 330 is used to adjust the distance between the needle bed 310 and the adjustment plate 320 .

[0051] The fixing member 340 is disposed on the telescopic member assembly 330 and is used to fix the relative positions of the needle bed 310 and the adjustment plate 320 .

[0052] In this embodiment, the multiple placement grooves 110 provided on the seed placement plate 100 can limit the position of the seeds, reduce the possibility of seeds sliding during the skin breaking process, and improve the accuracy of the needle puncture skin breaking.

[0053] During use, the seed coat thickness of seeds of the same type is first measured, and the seeds with the same seed coat thickness are placed one by one in the placement groove 110 of the same batch, and then the distance between the needle bed 310 and the adjustment plate 320 is adjusted by the telescopic member group 330, so that the length of the puncture needle 311 passing through the adjustment plate 320 is equal to the seed coat thickness. The fixing part 340 is then used to fix the needle bed 310 and the adjustment plate 320 to limit the distance between the needle bed 310 and the adjustment plate 320, so that the length of the puncture needle 311 extending out of the adjustment plate 320 remains unchanged, and then the needle assembly 300 is controlled to slide on the bracket 200 until the puncture needle 311 penetrates into the seed coat. When the adjustment plate 320 contacts the seed, the puncture needle 311 stops moving. At this time, the depth of the puncture needle 311 penetrating the seed is equal to the thickness of the seed coat, which can increase the seed's absorption of water and oxygen. By adjusting the distance between the needle bed 310 and the adjustment plate 320, the depth of the puncture needle 311 penetrating the seed can be guaranteed, reducing the occurrence of shallow or deep punctures in the seed coat and improving the seed germination rate.

[0054] Reference Figure 1 and Figure 2In one possible implementation, the telescopic member group 330 includes at least two first connecting rods 331 and at least two second connecting rods 332, and the two first connecting rods 331 and the two second connecting rods 332 are hingedly connected end to end to form a quadrilateral frame, wherein the ends of one of the first connecting rods 331 and one of the second connecting rods 332 are hingedly connected to the side wall of the needle bed 310, and the ends of the other first connecting rod 331 and the other second connecting rod 332 are hingedly connected to the side wall of the adjustment plate 320.

[0055] In this embodiment, the two first connecting rods 331 and the two second connecting rods 332 are hingedly connected end to end to form a quadrilateral frame. When the distance between the needle bed 310 and the adjustment plate 320 decreases, the length of the puncture needle 311 passing through the adjustment plate 320 increases, and the angle between the first connecting rod 331 and the second connecting rod 332 decreases. When the distance between the needle bed 310 and the adjustment plate 320 increases, the length of the puncture needle 311 passing through the adjustment plate 320 decreases, and the angle between the first connecting rod 331 and the second connecting rod 332 increases.

[0056] Reference Figure 2 In a possible implementation, the fixing member 340 is a bolt, which is inserted into the hinge point of the first connecting rod 331 and the second connecting rod 332 and is threadedly connected to the needle bed 310 or the adjustment plate 320.

[0057] In this embodiment, a bolt can be inserted into the hinge point of the first connecting rod 331 and the second connecting rod 332 and threadedly connected to the needle bed 310 or the adjustment plate 320, so as to fix the first connecting rod 331 and the second connecting rod 332 on the needle bed 310 or the adjustment plate 320, thereby fixing the telescopic member group 330, ensuring that the distance between the needle bed 310 and the adjustment plate 320 is not easy to change, thereby improving the accuracy of the puncture needle 311 breaking the skin.

[0058] Reference Figure 2 In a possible implementation, a locking piece 400 is further provided on the needle threading assembly 300 , and the locking piece 400 is used to fix the needle threading assembly 300 on the bracket 200 .

[0059] It is understandable that when adjusting the spacing between the needle bed 310 and the adjustment plate 320, it is necessary to ensure that one of the needle bed 310 and the adjustment plate 320 is fixed on the bracket 200, and the other slides on the bracket 200 to adjust the spacing between the needle bed 310 and the adjustment plate 320. The locking member 400 can fix the needle assembly 300 on the bracket 200, so as to facilitate the adjustment of the spacing between the needle bed 310 and the adjustment plate 320. After the needle bed 310 and the adjustment plate 320 are fixed by the fixing member 340, the locking member 400 is released, so that the needle assembly 300 slides on the bracket 200, so that the puncture needle 311 pierces the seed coat.

[0060] Reference Figure 2 In a possible implementation, the locking member 400 is a clamp, and the locking member 400 is fixed on the needle bed 310 or the adjustment plate 320 .

[0061] In this embodiment, the locking member 400 is a clamp, which is disposed on the needle bed 310 or on the adjustment plate 320 . The clamp can be locked on the bracket 200 , thereby fixing the needle threading assembly 300 on the bracket 200 .

[0062] Reference Figure 2 In a possible implementation, a measuring component group 500 is provided on the needle assembly 300, and the measuring component group 500 is used to measure the distance between the needle bed 310 and the adjustment plate 320 to control the length of the puncture needle 311 passing through the adjustment plate 320.

[0063] It can be understood that when adjusting the distance between the needle bed 310 and the adjustment plate 320, the measuring component group 500 can accurately display the distance between the needle bed 310 and the adjustment plate 320, thereby reducing the possibility of errors when adjusting the distance between the needle bed 310 and the adjustment plate 320, reducing the subsequent steps of fine-tuning the needle bed 310 or the adjustment plate 320, and improving the adjustment efficiency.

[0064] Reference Figure 2 In a possible implementation, the measuring component group 500 includes a fixed cylinder 510, in which a measuring rod 520 is slidably arranged, and a scale mark 530 is arranged on the measuring rod 520. The fixed cylinder 510 is fixed on the bottom plate of the needle bed 310 or the top plate of the adjustment plate 320.

[0065] It is understandable that when the distance between the needle bed 310 and the adjustment plate 320 increases, the measuring rod 520 gradually extends from the fixed tube 510, and when the distance between the needle bed 310 and the adjustment plate 320 decreases, the measuring rod 520 gradually inserts into the fixed tube 510, and the scale mark 530 on the measuring rod 520 can display the distance between the needle bed 310 and the adjustment plate 320, thereby improving the accuracy of adjusting the distance between the needle bed 310 and the adjustment plate 320. In other embodiments, the scale mark 530 on the measuring rod 520 can also directly display the length of the puncture needle 311 passing through the adjustment plate 320, thereby facilitating the control of the depth of the puncture needle 311 piercing the seed coat.

[0066] Reference Figure 3 In a possible implementation, it also includes a base 600, the bracket 200 is fixed on the base 600, and the seed plate 100 is slidably set on the base 600.

[0067] It is understandable that, since the number of puncture needles 311 on the needle bed 310 is less than the number of seeds on the seed plate 100, the seeds on the seed plate 100 need to be broken in batches, and the seed coat thickness of the seeds on the seed plate 100 is different. After each batch of skin breaking treatment, the length of the puncture needle 311 passing through the adjustment plate 320 needs to be readjusted. The seed plate 100 is slidably arranged on the base 600, so that each batch of seeds can be moved to the bottom of the puncture assembly 300 for skin breaking treatment.

[0068] Reference Figure 3 In a possible implementation, a receiving groove 610 is provided on the base 600, a first sliding groove 620 for inserting the seed plate 100 is provided on the side wall of the receiving groove 610, a second sliding groove 630 parallel to the first sliding groove 620 is provided on the side wall of the receiving groove 610, a support plate 700 for providing support for seeds is provided under the seed plate 100, the support plate 700 is slidably provided in the second sliding groove 630, and a collection box 800 is slidably provided on the bottom wall of the receiving groove 610.

[0069] It can be understood that in order to facilitate the collection of seeds after the skin is broken, a collection box 800 is slidably arranged on the base 600. When the seeds are completely broken, the support plate 700 is pulled out of the second sliding groove 630, so that the seeds in the placement groove 110 fall into the collection box 800, thereby realizing the collection of seeds.

[0070] Reference Figure 2 In a possible implementation, a lifting handle 312 is provided on the top plate of the needle bed 310 .

[0071] It is understandable that after the seeds are skinned, the piercing assembly 300 needs to be lifted vertically on the bracket 200 so that the piercing needle 311 can be pulled out of the seed coat, and the lifting handle 312 can facilitate the staff to lift the piercing assembly 300, and can also control the speed at which the piercing assembly 300 slides on the bracket 200, thereby reducing damage to the seeds caused by the piercing assembly 300 falling too fast.

[0072] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps recorded in the embodiments disclosed in the present application can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solutions disclosed in the embodiments of the present application can be achieved, and this document is not limited here.

[0073] The above specific implementations do not constitute a limitation on the protection scope of the embodiments of the present application. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the principles of the embodiments of the present application should be included in the protection scope of the embodiments of the present application.
