Description

Technical Field

[0001] The present invention relates to a de - stamening device for melon flowers, belonging to the technical field of agricultural equipment. Background Art

[0002] Melons contain a large amount of carbohydrates, citric acid, carotenoids, B - group vitamins, vitamin C, etc. They have crispy flesh and excellent taste and flavor, being the top grade among fruits. The per - unit yield of melons is high, and it has become a rapidly developing industry in the world fruit industry. The future demand for melons by humans will continue to increase. Melons are monoecious and dioecious plants, and their flowers have three types: male flowers, female flowers, and bisexual flowers (i.e., a flower has both pistils and stamens). Male flowers are all unisexual flowers, and most female flowers are bisexual flowers. In particular, the female flowers of cultivated varieties are almost all bisexual flowers. The stigmas of bisexual female flowers of melons are surrounded by 3 - 4 stamens, whose positions are lower than the stigmas and have normal pollen functions. In order to improve the high - yield and disease - resistance ability of melons, cross - breeding is selected. Therefore, during the process of growing melons, it is necessary to perform the de - stamening operation to avoid self - pollination and ensure the hybrid purity of seeds.

[0003] Currently, for the de - stamening work of melons, manual labor is mostly used. Operators use tweezers to pick and remove male flowers one by one, or use toothpicks to peel off male flowers one by one. The de - stamening process is time - consuming and laborious, and it is easy to miss male flowers. Summary of the Invention

[0004] The present invention aims to overcome the drawbacks of the prior art and provides a de - stamening device for melon flowers, which can accurately remove male flowers at one time, saving time and effort.

[0015] The present invention will be further described below in conjunction with embodiments.

[0016] Refer to Figure 1 and Figure 2 As shown in the figure, the present invention discloses a male flower removing device for melon flowers, including a housing 1, a pedicel clamping device 2, a female flower stigma protection cylinder 3, a male flower cutting device 4 and a controller 5. The interior of the housing 1 is divided into a cutting cavity 7 and a device fixing cavity 8 by an annular partition plate 6. The cutting cavity is located at the central position of the housing, and its lower end is open. During operation, the whole melon flower enters the cutting cavity. The female flower stigma protection cylinder 3 is fixed at the top of the cutting cavity 7, and the lower end of the female flower stigma protection cylinder 3 is open, used to cover the female flower stigma and protect the stigma from damage. The pedicel clamping device 2 and the male flower cutting device 4 are both fixed on the annular partition plate 6. The pedicel clamping device 2 is arranged below the male flower cutting device 4. The pedicel clamping device 2 includes an air pump 2-1, a flexible airbag 2-2 and an airbag support block 2-3. The air pump 2-1 is fixed on the outer wall of the annular partition plate 6. There are two airbag support blocks 2-3, symmetrically arranged on the inner wall of the annular partition plate 6. The edge of the air inlet of the flexible airbag 2-2 is hermetically wrapped on the airbag support block 2-3. The air pump 2-1 is communicated with the flexible airbag 2-2 through a pipe 2-4. One end of the pipe is communicated with the air outlet of the air pump, and the other end sequentially passes through the annular partition plate and the airbag support block and is communicated with the flexible airbag. The pipe is hermetically connected to the annular partition plate and the airbag support block. An air release valve 2-5 is arranged on the pipe. When the air pump works, it inflates the flexible airbag. The inflation time is set according to the actual situation. After inflation, the two flexible airbags clamp and fix the pedicel below the flower. Convex ribs are arranged on the wall of the flexible airbag to limit the shape of the flexible airbag after inflation and ensure that the two airbags can clamp the pedicel. A control switch 9 is arranged at the top of the housing. The controller 5 is arranged at the upper end inside the housing 1 and is electrically connected to the pedicel clamping device 2, the male flower cutting device 4, the air release valve 2-5 and the control switch 9.

[0017] There are two sets of male flower excision devices symmetrically arranged and fixed on the annular partition plate 6 respectively. Each set of male flower excision devices includes an electromagnet 4-1 and a cutter 4-2. The electromagnet 4-1 is fixed on the outer wall of the annular partition plate 6 through a fixing frame 4-3. One end of the iron core 4-4 at the center of the electromagnet 4-1 passes through the annular partition plate 6, and the cutter 4-2 is fixed at its end. The iron core is hermetically connected to the annular partition plate. The cutter 4-2 is located around the lower end of the female flower stigma protection cylinder 3. The cutting edge end of the cutter is set in an arc shape, which is convenient for removing the male flowers around the stigma at one time. The return spring 4-5 on the iron core 4-4 is located outside the annular partition plate 6. One end of the return spring 4-5 is fixedly connected to the outer wall of the annular partition plate 6, and the other end is fixed to the spring retaining piece 4-6 on the iron core 4-4. A limit block 4-7 is fixed at the other end of the iron core 4-4 to prevent the iron core from separating from the electromagnet main body. When powered on, the two iron cores move towards the center at the same time, driving the two cutters to move relatively to remove the male flowers. When powered off, under the action of the return spring, the iron core moves outwards and the cutter retracts.

[0018] The emasculation device of the present invention is additionally provided with a male flower collection device, and the excised male flowers are collected by this device. The male flower collection device includes an air extraction pipe 10, a male flower collection chamber 11, a filter screen 12 and a blower 13. The blower 12 is fixed inside the top end of the housing 1 and is electrically connected to the controller 5. The male flower collection chamber 11 is arranged at the top end of the housing 1. The filter screen 12 is obliquely fixed inside the male flower collection chamber 11. The air inlet of the blower 12 is communicated with the male flower collection chamber, and the air outlet leads to the external air or is connected to an external collection container. One end of the air extraction pipe 10 is communicated with the excision cavity 7, and the other end is communicated with the male flower collection chamber 11. The connection parts are all hermetically connected. A sealing cover 14 is arranged at the top end of the male flower collection chamber 11, and a handle is arranged on the sealing cover to facilitate the movement of the overall emasculation device.

[0019] Convex and concave grip patterns 15 are arranged on the outer side of the top end of the housing 1 to facilitate the hand to grip.

[0020] The control principle diagram of the present invention is recorded in Figure 3 and the control of each component is completed by the controller CPU.

[0021] When the stamen needs to be removed, press the button AJ (control switch). The CPU commands the pressure pump to work first, inflating the flexible airbag 2-2. After the flexible airbag is inflated, it expands, and the two flexible airbags 2-2 on both sides clamp the flower stalk tightly, positioning the flower stalk and preventing it from shaking. Then, the CPU outputs a control signal at the p1.1 port, causing the two electromagnets 4-1 fixed on both sides of the flower stalk to be energized and actuate. The two iron cores 4-4 extend simultaneously, and the arc-shaped cutters fixed at their ends actuate to cut off and drop the stamens. The present invention is provided with a female flower stigma protection cylinder 3, which protects the female flower stigma, prevents the female flower from being injured, and at the same time provides the function of an anvil for the removal of stamens. After the stamens are removed, due to the blocking of the entire passage by the flexible airbag, the stamens do not scatter but fall on the surface of the flexible airbag. At the same time, the CPU issues a command to output a signal from the port p1.2, causing the triode T1 to be energized and actuate, and the relay J1 to be energized. After the emitter load relay of the triode T1 is energized, its normally open contact J1-1 closes, and the fan 13 rotates. The airflow attracts the male flowers and enters the male flower collection chamber 11 along the air extraction pipe 10, or adheres to the lower part of the filter net 12. After the stamens are collected, the CPU is powered off to prepare for the removal of the next stamen.

[0022] The air pump and the electromagnet of the present invention are directly connected to the output ports of the CPU. If the load-carrying capacity of the output ports is insufficient, a relay can be installed between the output ports and the air pump or the electromagnet according to the connection method of the fan 13 to provide relay.

[0023] Stamen removal process: Place the stamen removal device of the present invention on the melon flower. The female flower stigma protection cylinder covers the female flower stigma. Press the control switch, and the air pump in the flower stalk clamping device starts to inflate the flexible airbag. The two airbags clamp the flower stalk below the flower tightly. The electromagnet is energized and actuates, and the iron core drives the cutter to move towards the center female flower stigma protection cylinder. The cutter contacts the outer wall of the female flower stigma protection cylinder, cutting off the male flower. The fan starts, sucking the cut male flower into the male flower collection chamber under negative pressure to complete the collection. Power off, open the air release valve, and the gas in the flexible airbag is released. The two airbags separate from the flower stalk. At the same time, the iron core resets under the action of the return spring, lifting the entire stamen removal device to perform the next stamen removal operation.
