Description

Technical Field

[0001] This utility model relates to the field of breeding and processing, and in particular to the silkworm breeding industry. Background Technology

[0002] Currently, most silkworm rearing environments in China are not suitable for the growth and development of silkworms. The silkworms raised in such environments are mostly of poor quality. Some semi-automatic rearing equipment on the market can improve the quality to a certain extent, but it requires continuous human supervision and adjustment to achieve the desired rearing environment.

[0003] Chinese patent document CN220211555U discloses a multi-layer fixed silkworm rearing frame that is easy to move. The device uses a fixing screw set in the support device. When the fixing screw is rotated, it moves left and right. When the fixing screw is disengaged from the frame, the frame can be removed, thereby achieving the effect of replacing the frame.

[0004] Chinese patent document CN107897133A discloses a multifunctional silkworm rearing device. This device has three layers of plates, with the feeding tray embedded in the upper plate. A vibration motor drives the upper plate to vibrate, which in turn drives the feeding tray to vibrate. This causes the silkworm excrement on the feeding tray to fall through the through holes into the inclined middle plate. The middle plate then guides the silkworm excrement into a silkworm excrement collection box. The vibration of the upper plate also drives the middle plate to vibrate, ensuring that the silkworm excrement does not remain on the middle plate and falls completely into the silkworm excrement collection box, thus completing the automatic cleaning and collection of silkworm excrement on the feeding tray.

[0005] By reviewing the two Chinese patent documents briefly described above, it can be concluded that in current silkworm breeding technology, the feeding rack structure has achieved rich technological results in the placement and recycling of silkworm products. However, when silkworm products are promoted to ordinary silkworm farmers, they find it difficult to learn from breeding enterprises and purchase expensive temperature control equipment to assist domestic silkworms in growth and production. Due to the influence of the growth environment, the quality of products produced by domestic silkworms is inconsistent, resulting in the economic value of silkworm farmers' production being far lower than the value of their labor. Therefore, this has led to the problem of fewer silkworm farmers.

[0006] With the vision of "reducing the breeding costs for silkworm farmers", our company has proposed a high-quality, fully automated, graded feeding technology to achieve high efficiency and high quality in feeding. The streamlined structure and simple operation interface, coupled with the price of 1 / 3 to 1 / 4 of imported equipment, make it more suitable for a wide range of domestic customers.

[0022] The beneficial effects of this utility model are:

[0023] This invention features a temperature control component at the top of the temperature control device. By activating a fan, air from the outside is drawn into the air duct. A dust filter removes dust from the air. The air from the air duct is then introduced into the air supply pipe. When heating is required, the heater can be activated to heat the air flowing inside the air supply pipe. When humidification is required, a humidifier can be activated to spray water mist to humidify the air flowing inside the air supply pipe. This achieves the effect of heating or humidifying the air flowing into the culture tank by activating the temperature control component and spraying appropriate hot and humid air, thereby rapidly changing the internal temperature of the culture tank and achieving temperature control within the culture tank.

[0024] This invention features an adjustment mechanism at the top of the temperature control device. When the gas flowing from the gas supply pipe into the support shaft and then into the mounting shaft via the guide of the support shaft, the connecting sleeve receives the hot or humid gas flowing in from the gas supply pipe. The hot or humid gas is then ejected by the nozzle, causing it to circulate within the cultivation tray. The drive shaft is then activated, causing the drive screw to rotate via a nested transmission mechanism. The drive screw and drive gear engage in threaded transmission, and the drive gear, through a locking mechanism, rotates the support shaft, which in turn rotates the mounting base and mounting shaft. The mounting shaft, in turn, rotates the auxiliary fan blades, which in turn fan the humid and hot gas to quickly integrate into the cultivation tray, rapidly changing the temperature inside the tray. This achieves the efficiency of adjusting the humid and hot gas integration into the cultivation tray through the adjustment mechanism, allowing the cultivation tray to be quickly regulated to a suitable temperature, thus creating a suitable environment for silkworm rearing.

[0040] In this embodiment, the temperature control component 67 and the adjustment mechanism 68 are arranged at the same level at the rear end of the mounting box 61. The control terminal 69 is internally equipped with an MCU series control chip, with six major function modules: heating, humidification, ventilation, heat replenishment, humidification, and display control.

All of the above products are existing products and can be selected according to requirements. The specific functions include temperature and humidity detection, data transmission, and storage.

[0041] Please see Figures 8-11 This utility model provides a temperature and humidity controller for silkworm breeding. The adjustment mechanism 68 includes a built-in motor 681, a housing 682, a transmission shaft 683, a transmission screw 684, a transmission gear 685, and a support shaft 686. The built-in motor 681 is installed on the housing 682, and the housing 682 is connected to the left end of the temperature control component 67. The built-in motor 681 is connected to the right end of the transmission shaft 683 by a coupling. The transmission shaft 683 and the transmission screw 684 are internally nested for transmission. The transmission screw 684 and the transmission gear 685 are meshed on the outside for transmission. The transmission gear 685 and the bottom of the support shaft 686 are engaged for transmission. The top of the support shaft 686 is provided with a mounting seat 6F.

[0042] The temperature control component 67 includes a mounting box 671, an air duct 672, a dustproof net 673, a fan 674, a heater 675, an air supply pipe 676, and a humidifier 677. The mounting box 671 is fixed to the rear end of the mounting housing 61. The air duct 672 is located at the right end of the mounting box 671. The dustproof net 673 is fixed to the inside of the air duct 672. The fan 674 is fixed to the inside of the mounting box 671 and is connected to the right end of the air supply pipe 676. The heater 675 is installed at the left end of the fan 674 and is connected to the rear end of the air supply pipe 676. The humidifier 677 is installed at the left end of the heater 675 and is connected to the rear end of the air supply pipe 676.

[0043] In this embodiment, the heater 675 is a wind-heated pipe heater, and the humidifier 677 can be a PCM model industrial humidifier. Both the heater 675 and the humidifier 677 are electrically connected to the control terminal 69. The heater 675 and the humidifier 677 are arranged at the same horizontal level at the rear end of the air supply pipe 676. The support shaft 686 and the mounting base 6F have hollow structures inside, ensuring that the bottom of the support shaft 686 can introduce warm and humid air into the interior of the mounting shaft 6A, and then supply gas from the mounting shaft 6A to the interior of the connecting sleeve 6C and the nozzle 6D.

[0044] See Figures 1-5 When in use, place the fixing plate 1 horizontally in a cool place. After placing the culture tube 2 into the inside of the adjusting bracket 5, manually drag the culture tray 3 outward to place the domesticated silkworms and cultured mulberry leaves into the inside of the culture tube 2 for feeding.

[0045] During the rearing process, the transmission motor 54 can drive the transmission link 55 to swing, so that the transmission link 55 can move the lower plate 53 up and down. When the culture tube 2 comes into contact with the fixed plate 1, the culture tube 2 is lifted by the fixed plate 1, so that the rearer can observe the domesticated silkworms inside the two sets of culture trays 3 at the same time, which makes it easier for the rearer to observe and compare them simultaneously. During this process, the limiting block 4 prevents the culture tube 2 from falling off accidentally. Then, by activating the adjusting bracket 5, the culture tube 2 is driven to move up and down. When the culture tube 2 moves to the appropriate position, it can ensure that the rearer can observe the domesticated silkworms inside the two sets of culture trays 3 at the same time, which is beneficial for the staff to record the growth of the domesticated silkworms.

[0046] Furthermore, by operating the contact screen 63, the contact screen 63 can control the PLC controller 65. The PLC controller 65 transmits telecommunications with the sensor assembly 6E through the sensor probe at the end, causing the humidity sensor 6Ea and the temperature sensor 6Eb to sense the real-time temperature and humidity inside the culture tube 2.

[0047] The control terminal 69 is controlled by the temperature and humidity sensed by the PLC controller 65. The control terminal 69 drives the heater 675 and the humidifier 677, which then heat and humidify the gas according to the temperature and humidity data.

[0048] When heating and humidification are required, the six modules inside the control terminal 69 control the equipment to start heating and humidification in real time, and start the internal fan 674 to rotate. The fan 674 guides the airflow inside the culture cylinder 2, thereby heating, humidifying, exchanging air, and replenishing heat and moisture to maintain the internal temperature of the culture cylinder 2.

[0049] Simultaneously, the temperature control component 67 and the adjustment mechanism 68 are controlled by the control terminal 69. The fan 674 is started to draw air from the outside into the air duct 672. The dust filter 673 filters the dust contained in the gas. The gas from the air duct 672 is introduced into the air supply pipe 676. When heating is required, the heater 675 can be started to heat the gas flowing inside the air supply pipe 676. When humidification is required, the humidifier 677 can be started to spray water mist to humidify the gas flowing inside the air supply pipe 676. Then, the temperature control component 67 is started to introduce gas and spray appropriate hot and humid air to heat or humidify the gas flowing into the culture cylinder 2, thereby quickly changing the internal temperature of the culture cylinder 2 and making the internal temperature of the culture cylinder 2 controllable.

[0050] Next, when the gas flowing inside the gas supply pipe 676 flows into the support shaft 686 and is guided by the support shaft 686 into the mounting shaft 6A, the connecting sleeve 6C can receive the hot or humid gas flowing in from the gas supply pipe 676. The hot or humid gas is then sprayed out by the nozzle 6D, so that the hot or humid gas inside the culture cylinder 2 is activated. The drive shaft 683 is then driven to rotate, causing the drive screw 684 to rotate through a nested transmission. The drive screw 684 and the drive gear 685 are threadedly driven, and the drive gear 685 rotates the support shaft 686 through a fitted and fixed manner. This causes the mounting base 6F to rotate the mounting shaft 6A, and the mounting shaft 6A can rotate the auxiliary fan blade 6B.

[0051] By using auxiliary fan blades 6B to rapidly integrate moisture and heat into the cultivation cylinder 2, the internal temperature of the cultivation cylinder 2 is quickly changed. The efficiency of this rapid integration is then adjusted by the regulating mechanism 68, allowing the cultivation cylinder 2 to be quickly regulated to a suitable temperature, thus creating an ideal environment for silkworm growth. Furthermore, a temperature control device 6, mounted below the cultivation cylinder 2, simultaneously sprays and diffuses appropriately warm or moist air, rapidly altering the internal temperature of the cultivation cylinder 2 to create a suitable environment for silkworm growth. This improves the quality of silkworm products, enhances the economic value for silkworm farmers, and solves the problem of inconsistent product quality caused by the difficulty in controlling the temperature of the silkworm growth environment in traditional silkworm rearing techniques.

The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.
