Description

Technical Field

[0001] This invention relates to a device for precisely collecting irregularly shaped seeds, belonging to the technical field of seed collection boxes. Background Technology

[0002] Seed box arrays, due to space constraints, typically have a large depth-to-diameter ratio and are densely packed. Collection is usually achieved using clamps and suction cups. Initially, the clamps used rigid materials; however, insufficient clamping force resulted in inadequate friction, failing to pick up the seeds; excessive clamping force easily damaged them. Later, flexible materials were used instead of rigid ones, alleviating seed gripping and damage, but the smooth, curved surface of the seeds still prevented achieving a precise collection rate. Suction cups are effective at collecting relatively regular, flat seeds, but they are ineffective for irregularly shaped, non-flat seeds. Therefore, a precise collection device for irregularly shaped seeds remains lacking. Summary of the Invention

[0003] The purpose of this invention is to solve the problems existing in the prior art and to provide a device for accurately collecting irregularly shaped seeds.

[0017] Example 1: As Figure 1-3As shown, this embodiment involves a precise seed collection device for irregularly shaped seeds, comprising: a seed display and collection box, a pressing head, a collection tray, a linear motion mechanism, and a vertical motion device for the pressing head. The linear motion mechanism consists of three linear guide rails. Linear guide rail one and linear guide rail two are arranged in parallel with the collection tray placed in between. Linear guide rail three is vertically arranged on the two parallel linear guide rails. Linear guide rail three moves along linear guide rail one and linear guide rail two. The vertical motion device for the pressing head is arranged on linear guide rail three and moves along linear guide rail three. An image recognition and acquisition device is arranged on the side of the vertical motion device for the pressing head. The pressing head is fixed at the lower end of the vertical motion device for the pressing head, thereby driving the pressing head to perform vertical movement. The seed display and collection box is placed on the collection tray. Seed bins are evenly arranged on the seed display and collection box. The upper part of the seed bin is a cylinder, and the lower part of the cylinder inside the seed bin is a frustum. The head shape of the pressing head is fitted with the seed bin with a clearance. A flexible bottom plate is provided at the bottom of the seed bin, and flexible holes are opened on the flexible bottom plate.

[0018] The present invention provides a device for precisely collecting irregularly shaped seeds, wherein the inner wall of the seed chamber is made of a rigid material.

[0019] The present invention provides a device for precisely collecting irregularly shaped seeds, wherein the thickness of the flexible holes is slightly less than the thickness of the seeds, and the diameter of the flexible holes is slightly less than the maximum diameter of the seeds.

[0020] The present invention discloses a device for precisely collecting irregularly shaped seeds, wherein the bottom of the extrusion head is provided with a protrusion, the diameter of which is slightly smaller than that of the flexible hole, and the depth of which is greater than half of that of the flexible base plate.

[0021] The present invention provides a device for precisely collecting irregularly shaped seeds, which further includes an image recognition acquisition device and a controller. The output end of the image recognition acquisition device is connected to the input end of the controller, and the output end of the controller is connected to a linear motion mechanism and a vertical motion device for the extrusion head.

[0022] The present invention provides a device for precisely collecting irregularly shaped seeds, wherein the extrusion head is made of nylon and coated with a Teflon coating.

[0023] Example 2: Figure 1-3 As shown, the specific working process of the irregular seed precise collection device involved in this embodiment is as follows:

[0024] The seed array box contains seeds in its seed bins. Image recognition identifies whether there are seeds in the seed bins and transmits the identification information to the controller. The controller guides the linear motion mechanism (two linear motion mechanisms in a cross combination) to move the extrusion head until its axis coincides with the axis of the seed bin. The vertical motion device of the extrusion head drives the extrusion head to move vertically. The extrusion head falls vertically to the flexible base plate, extruding the seeds in the seed bins into the seed collection box. The extrusion head rises vertically, and the image recognition device verifies whether the seeds in the seed bins have fallen. The extrusion action is completed, and the machine moves to the next seed bin.

[0025] The extrusion head is shaped to fit the seed chamber. The sidewalls of the seed chamber are made of rigid material, while the bottom is made of flexible material with flexible holes. The extrusion head moves vertically until it coincides with the bottom surface of the seed chamber. The seeds are pressed through the bottom holes and fall into the seed array collection box, completing the precise collection of a single seed. The extrusion head moves to different seed chambers and repeats the above process to complete the collection of the specified seeds.
