Description

Technical Field

[0001] The invention relates to an insect breeding tank and a breeding system, as well as a continuous breeding method, and belongs to the technical field of insect breeding. Background Art

[0002] Insect larvae can feed on livestock and poultry manure and kitchen waste, thus producing high-priced insect protein feed. Due to their rapid reproduction, wide range of food, high conversion rate, easy management, low feeding cost, and good animal palatability, they are widely used in processing solid kitchen residues, livestock and poultry manure, etc. However, the high energy consumption required for specific environmental conditions during the artificial breeding of insect larvae restricts the rapid development of the industry.

[0003] In the process of insect larvae breeding, it is very important to effectively adjust the breeding temperature and humidity through a heat exchange device to meet the breeding requirements of insects. The conventional air circulation method for adjusting the material temperature has the following problems: (1) The use of hot and cold air to control the breeding environment temperature requires large breeding equipment and high energy consumption; (2) During the heating and cooling process of the hot and cold air, the gas flows frequently, which will cause a large change in the humidity of the material, making the material unsuitable for insect breeding, thereby reducing the breeding efficiency. Water is often used as an excellent thermal conductor because of its high specific heat. Announcement No. CN221710937U, Patent Name: A water-heated insect breeding device and system thereof, which heats up and cools the material through a heat exchange tube, and the water and the material in the heat exchange tube are separated by multiple layers of material, which affects the heat conduction; Announcement No. CN210113967U Patent Name: A black soldier fly breeding device, which adjusts the temperature through a thermal conductor in an outer pool, uses a large amount of thermal conductor, and the temperature adjustment is slow, which is prone to uneven temperature.

[0004] In addition, the current insect larvae farming mainly includes ground farming mode and three-dimensional farming mode. The three-dimensional farming mode has attracted widespread attention due to its high space utilization rate, but three-dimensional farming has put forward higher requirements on the temperature and humidity environment control of the farming system.

The front and rear sides of the water tank are fixed on the support plate of the insect feed transmission device or are integrally formed with the support plate. Furthermore, reinforcing ribs are provided inside the water tank to enhance the load-bearing strength of the water tank. The height of the water tank is 10 to 100 mm.

[0012] Several layers of breeding troughs are arranged in a breeding box in a staggered manner in the length direction, and the length direction refers to the vertical direction from one side plate of the breeding box to the other side plate; the staggered arrangement refers to two layers of breeding troughs adjacent to each other, the active roller of one layer and the driven roller of the other layer are located on the same side of the breeding box.

[0013] The breeding system also includes two driving motors; the active roller of each breeding trough is mechanically connected to one of the driving motors through a sprocket and a chain, so that the transmission belts of each two adjacent breeding troughs run in opposite directions.

[0014] The breeding system also includes a plurality of connecting water pipes for connecting the water storage devices of two adjacent layers; the connection method is: the breeding tank is divided into two groups, the upper and lower groups, with the middle breeding tank located in the breeding box as the boundary, and the water storage devices in the breeding tanks of the two groups are connected by connecting water pipes to form two one-way water flow channels; that is, the water inlet at the driven roller end of the breeding tank of the lowest layer of the upper group of breeding tanks is used as the water inlet of the upper group of breeding tanks and connected to the external water supply device, and the connecting water pipe connects the water inlet at the active roller end of the breeding tank of the lowest layer of the group with the water inlet at the driven roller end of the breeding tank of the upper adjacent layer, and connects upward in sequence, and the two connecting pipes at the breeding tank of the top layer are connected to the water inlet of the driving roller end of the breeding tank of the lowest layer of the group.

The connecting water pipe connects the water inlet at the active roller end of the uppermost breeding tank of the group with the water inlet at the driven roller end of the adjacent breeding tank below, and is connected downward in sequence. One of the two water inlets located at the bottom breeding tank is connected to the water storage device of the upper breeding tank, and the other is used as the water outlet of the lower breeding tank to be connected to the external water outlet device.

[0016] The breeding system also includes an air inlet and an air outlet respectively arranged on the side panels of the breeding box; wherein the air inlet is arranged on the side panel near one end of the discharge port, and is located at a passage position between the breeding trough on the lowest layer and the breeding trough on the upper layer; the air outlet is arranged on the side panel near one end of the feeding port, and is located at a passage position between the breeding trough on the top layer and the top panel of the breeding box; thus, an air supply system from bottom to top, which is opposite to the direction of insect feed transmission, is formed in the closed breeding space enclosed by the side panels, the top panel of the breeding box and the side panels of the breeding troughs on each layer.

[0017] The breeding system also includes baffles of several breeding troughs arranged on the side panels of the breeding box body. The baffles are arranged on the side panels above the driven rollers of each layer of breeding troughs, and the baffles are tightly connected to the inner walls of the side panels close to the driven rollers to prevent materials from falling into the gap between the driven rollers and the water tank, and also to prevent the lower layer of airflow from passing through the two sides of the driven rollers into the upper layer, forming an airflow short circuit.

[0018] Furthermore, a feeding port is arranged on the side plate close to the driven roller end of each layer of the breeding trough to realize multiple feeding.

[0019] Furthermore, the outside of the breeding box is coated with an insulation layer to reduce energy loss.

[0020] Furthermore, an observation window is provided on the support plate of each layer of the breeding tank to observe the growth of the insects.

[0021] The water storage device of each layer of the breeding tank in the above breeding system can also be constructed in the following manner: the water storage device includes a tank body, a water flow channel plate, a water inlet, and a water distribution pipe. The tank body is composed of a transverse plate, a front plate, and a rear plate, which can be a plurality of plates spliced ​​together or bent into an integral shape; the water flow channel plate is installed on the lower surface of the tank body transverse plate and is tightly connected to the lower surface of the tank body transverse plate; the water distribution pipe is installed on the lower surface of the tank body transverse plate and is located at both ends of the water flow channel plate in the length direction; a water inlet is provided on each side of the front plate of the tank body, which is respectively connected to the water distribution pipes at both ends.

[0022] More specifically, the water flow channel plate contains a structure of several parallel grooves, which may be wavy or corrugated, etc.; the upper surface of the water flow channel plate is tightly connected to the lower surface of the trough body cross plate, and the extension direction of the parallel grooves is consistent with the length direction and is installed under the trough body cross plate; in this way, in each layer of the breeding trough, the two water inlets and the water distribution pipes, the water flow channel plate, and the trough body cross plate form several independent water flow channels.

[0023] The front plate and the rear plate of the trough body of the water storage device are fixed on the support plate of the insect material transmission device or are integrally formed with the support plate, and the water storage device is located below the transmission mesh belt of the insect material transmission device, and the transmission mesh belt is in contact with the upper surface of the trough body transverse plate of the water storage device. The upper surface of the trough body transverse plate of the water storage device is smooth and flat, ensuring that the transmission mesh belt in contact therewith runs smoothly.

[0024] Furthermore, a support member may be provided at the bottom of the water channel plate.

[0027] (2) The total effective length of the transmission mesh belt is obtained by deducting the part covered by the baffle from all transmission mesh belts;

[0028] (3) Divide the total effective length of the transmission belt according to the number of divisions obtained to obtain the daily forward length of the transmission belt;

[0029] (4) starting the drive motor to drive the conveyor belt, and the insect food and larvae are placed on the conveyor belt through the feeding port and the larvae placement port. When the length of the food reaches the daily forward length of the conveyor belt, the drive motor is stopped;

[0030] (5) Water at 20 to 35 degrees Celsius is fed into the water inlets of the upper and lower breeding tanks to control the temperature of the food in the breeding tanks and provide temperature conditions for the rapid growth of the larvae. After passing through each water storage device, the water is discharged from the water outlets of the top and bottom layers respectively;

[0031] (6) Dry air at 20 to 35 degrees Celsius is fed in through the air inlet, and is discharged from the exhaust port through each layer of the breeding tank in the opposite direction of the transmission mesh belt.

[0032] (7) One day later, step (4) is repeated, and the food and larvae provided on the previous day are transferred to the conveyor belt with the next daily forward length, and the original positions are replaced by new food and larvae;

[0033] (8) Repeat step (4) every day until the larvae put in on the first day are discharged from the discharge port after a feeding cycle;

[0034] After that, step (4) and the discharging process are repeated once a day to achieve continuous feeding and discharging.

[0035] The present invention also provides another mode of a continuous insect culture method, which uses the above-mentioned continuous insect culture system and includes the following steps:

[0036] (1) Determine the insect rearing time;

[0037] (2) The total effective length of the transmission mesh belt is obtained by deducting the part covered by the baffle from all transmission mesh belts;

[0038] (3) The forward speed of the conveyor belt is obtained by dividing the total effective length of the conveyor belt by the feeding time;

[0039] (4) starting the drive motor to drive the conveyor belt at the obtained forward speed, and continuously and evenly adding insect food and larvae;

[0040] (5) Water at 20 to 35 degrees Celsius is fed into the water inlets of the upper and lower breeding tanks to control the temperature of the food in the breeding tanks and provide temperature conditions for the rapid growth of the larvae. After passing through each water storage device, the water is discharged from the water outlets of the top and bottom layers respectively;

[0041] (6) Dry air at 20 to 35 degrees Celsius is fed in through the air inlet, and is discharged from the exhaust port through each layer of the breeding tank in the opposite direction of the transmission mesh belt.

[0042] (7) After a feeding cycle, the feed outlet begins to discharge continuously.

[0043] The present invention also provides an insect breeding tank, which includes a tank body, a water flow channel plate, a water inlet, and a water distribution pipe; wherein the tank body is composed of a transverse plate, a front plate, and a rear plate; the water flow channel plate contains a structure of several parallel grooves, which are installed on the lower surface of the tank body transverse plate, the upper surface of the water flow channel plate is tightly connected to the lower surface of the tank body transverse plate, and the extension direction of the parallel grooves is perpendicular to the front plate or the rear plate of the tank body; the water distribution pipe is installed on the lower surface of the tank body transverse plate, located at both ends of the water flow channel plate, and connected to the water flow channel plate; a water inlet is arranged on both sides of the front plate of the tank body, respectively connected to the water distribution pipes at both ends; in this way, the two water inlets and the water distribution pipe, the water flow channel plate, and the tank body transverse plate form several independent water flow channels. When breeding insects, the larvae of the insects are placed on the upper surface of the tank body transverse plate for breeding.

[0044] The present invention also provides an insect breeding system, which comprises at least a plurality of the above-mentioned insect breeding troughs and a larvae transmission mesh belt, wherein the larvae transmission mesh belt is arranged closely to the upper surface of the horizontal plate of the trough body; during breeding, the larvae of the insects are arranged on the transmission mesh belt.

[0045] The present invention achieves the following beneficial effects:

[0046] 1) Insect food and larvae enter from the top breeding tank, are transported by the conveyor belt, and are discharged from the bottom breeding tank after breeding. During the process, they pass through multiple layers of breeding tanks, and the food and larvae are turned over every time they pass through a layer, so that the food will not be hardened and can be quickly consumed by the larvae; it also makes the material looser, drier, and easier to screen.

[0047] 2) The porous mesh belt allows the food to be better in contact with the water tank while being transported, which accelerates the heat transfer between the food and the water tank, making it easier to control the temperature.

[0048] 3) Dry air enters from the bottom breeding tank and is discharged from the top breeding tank in reverse. The bottom material can be dried quickly, and the gas is already moist when it reaches the top layer, so that the food in the upper breeding tank will not dry too quickly and reduce the larvae's consumption. On the other hand, the water content of the inlet and outlet gas can be greatly increased, thereby greatly reducing the ventilation volume and reducing the environmental control cost.

[0049] 4) Cooling water enters from the middle breeding tank and is discharged from the top and bottom layers in two directions, effectively removing the heat generated by the middle breeding tank while heating the top and bottom breeding tanks, increasing the activity of the larvae in the top breeding tank and accelerating the evaporation of water in the materials in the bottom breeding tank.

[0050] 5) For aquaculture tanks using water flow channel plates, the water flow channel plates are tightly connected to the trough body transverse plates of the water storage device, which can not only greatly improve the strength of the trough body transverse plates and reduce the material usage of the trough body, but also greatly improve the pressure bearing capacity of multiple small water flow channels formed by the water flow channel plates and the trough body transverse plates, thereby accelerating the water flow speed and enhancing the heat exchange effect.

In this embodiment, the number of breeding troughs 2 arranged is six, and the number of layers can actually be set as needed. The active roller 201 and the driven roller 202 are installed on the support plate 205 through the bearing seat 207, and the transmission mesh belt 203 is installed on the active roller 201 and the driven roller 202; the water tank 204 is arranged between the transmission mesh belts 203 of the upper and lower breeding layers, and the transmission mesh belt 203 is in contact with the top surface of the water tank 204 of the breeding trough layer; water inlets 208 are arranged at both ends of the side of the support plate, and there are rib plates 206 inside the water tank; there is a support plate 205 Observation window 209; top plate 3 is installed on the top of the top breeding tank 2, and a feeding port 301 and a larvae throwing port 302 are provided on the top plate 3, and the feeding port 301 and the larvae throwing port 302 are at one end of the driven roller of the top breeding tank 2; bottom plate 4 is installed at the bottom of the water tank 204 of the bottom breeding tank 2, and a discharge port 401 is provided on the bottom plate 4, and the discharge port 401 is directly below the active roller of the bottom breeding tank; side plates 5 are installed at both ends of the breeding tank 2, and are connected to the support plate 205, the top plate 3, and the bottom plate 4 form a closed breeding space; the air inlet 501 is arranged on the side plate at one end of the discharge port 401; the exhaust port 502 is arranged on the side plate at one end of the feeding port 301; a baffle 503 is arranged above the driven roller 202, and the baffle 503 is tightly connected to the adjacent side plate 5 to prevent the material from falling into the gap between the driven roller 202 and the water tank 204, and prevent the lower layer of gas from passing through the two sides of the driven roller 202 to enter the upper layer to form an air flow short circuit; from top to bottom, a feeding port 504 is arranged above the driven roller 202 of the second, fourth, and sixth layers of breeding troughs 2 to achieve multiple feeding; the active roller 201 on every other layer of breeding trough 2 is mechanically connected to the drive motor 6 through the sprocket 8 and the chain 9, so that the power output by the drive motor 6 is transmitted to each active roller 201. In this embodiment, two drive motors 6 are arranged, and the rotation directions of the two drive motors 6 are opposite.

[0063] From top to bottom, the first, second and third layers of breeding troughs 2 form a group, and the fourth, fifth and sixth layers of breeding troughs 2 form a group, which are respectively connected to water pipes, and the water inlets 208 of adjacent breeding troughs 2 are connected together.
