Description

Technical Field

[0001] This invention relates to the field of earthworm harvesting equipment technology, specifically to an earthworm harvesting device. Background Technology

[0002] Earthworms, as high-quality raw materials for bio-fertilizers, aquaculture feed, and pharmaceuticals, are experiencing continuously growing market demand, driving the rapid development of the large-scale earthworm farming industry. However, the earthworm harvesting process still faces many technical bottlenecks: traditional harvesting methods rely mainly on manual digging and sieving, which is not only labor-intensive and inefficient, making it difficult to meet the harvesting needs of large-scale farming, but also easily causes mechanical damage to earthworms during operation, affecting product quality. Therefore, developing a professional earthworm harvesting device that is highly adaptable, efficient in harvesting, has a low damage rate, and is easy to operate has become an urgent need for the industry. Summary of the Invention

[0003] The purpose of this invention is to provide an earthworm harvesting device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an earthworm harvesting device, comprising a frame, a harvesting device, a feeding cylinder, and a transmission device;

[0005] The chassis is a flat trailer chassis, and the vehicle drive system is installed on the chassis. A control panel is installed on the front right side of the chassis, and the control panel is equipped with a driving platform and operating system.

[0006] A mounting frame is installed on the top of the frame, a harvesting device is installed on the front side of the mounting frame, and a feeding cylinder is installed on the rear side of the mounting frame;

[0007] The harvesting device includes a conveyor belt and harvesting claws. The conveyor belt extends forward at an angle to the ground. The conveyor belt is a corrugated conveyor belt with corrugated folds evenly distributed on its surface. The corrugated folds work in conjunction with the harvesting claws to grasp the soil and prevent it from falling off during the upward transport process.

[0008] A feeding roller is horizontally mounted on the top of the mounting frame, and feeding rods are evenly distributed on the feeding roller. The feeding rods are located above the harvesting claws. The feeding cylinder is located on the rear side of the harvesting device, and the rear end of the feeding cylinder is inclined downward.

[0009] The mounting frame is equipped with a transmission device, which includes a transmission machine, a transmission chain, and transmission gears. The transmission chain connects the transmission machine and the transmission gears to realize power transmission and maintain the continuous operation of the conveyor belt and the feeding roller.

[0010] Preferably, the harvesting claws are distributed near the wavy folds. When the conveyor belt rotates, the harvesting claws dig up the soil and transport it towards the lower cylinder as the conveyor belt moves.

[0011] Preferably, a horn is provided at the tail end of the feeding cylinder; a gear ring is provided at the front end of the feeding cylinder, and the feeding cylinder is rotatably mounted on the mounting frame. The gear ring meshes with one of the transmission gears, and the feeding cylinder is driven to rotate continuously at a uniform speed through the transmission device.

[0012] After the earthworms are propelled into the feeding cylinder by the feeding roller, the earthworms are slowly transported downwards by the rotation of the feeding cylinder. The earthworms can be continuously collected by installing a collection bucket at the rear end of the frame.

[0013] Preferably, after the conveyor belt grabs the soil and passes through the feed roller, it continues to rotate downwards. A guide plate is installed between the frame and the conveyor belt to guide the soil to the ground after it falls.

[0014] Hydraulic rods are symmetrically installed on both sides of the conveyor belt to adjust the tilt angle of the conveyor belt and adapt to breeding ridges of different heights.

[0015] Preferably, the conveyor belt is made of food-grade rubber and leak-proof baffles are installed on both sides of the conveyor belt to prevent soil from overflowing from both sides; the harvesting claws are forged from manganese steel, have an arc-shaped structure, and the tips are blunted; the harvesting claws are connected to the conveyor belt with high-strength bolts.

[0016] Preferably, the transmission device adopts a combination transmission method of motor-reduction gearbox-transmission chain. The transmission motor is selected as a 1.5-2.2kW variable frequency motor, the reduction gearbox transmission ratio is 1:20 to ensure stable output torque; the transmission chain is made of stainless steel, the surface is treated with anti-rust treatment, and it is equipped with an automatic tensioning device.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This solution employs a flat trailer frame design with a width adapted to the spacing of mainstream earthworm farming ridges. Combined with a four-wheel drive system and independent suspension, it ensures stability when traveling between ridges. Hydraulic rods on both sides of the conveyor belt allow for flexible adjustment of the tilt angle, precisely adapting to farming ridges of varying heights and meeting diverse operational needs. The synergistic design of the corrugated conveyor belt and arc-shaped manganese steel harvesting claws significantly improves soil uniformity. Combined with an independently adjustable conveyor belt and feeding rollers, it achieves efficient linkage between soil excavation and earthworm separation, greatly improving harvesting efficiency and making it suitable for continuous operation in large-scale earthworm farming bases.

[0019] The harvesting claws are forged from manganese steel and passivated to prevent scratching earthworms during digging; the feeding rod is made of elastic rubber with an arc-shaped gripping head at the end, which efficiently separates earthworms from the soil while reducing damage caused by rigid collisions; the feeding cylinder adopts a low-speed uniform rotation design with an anti-stick coating sprayed on the inner wall. Combined with the gravity conveying principle, it effectively prevents earthworms from clogging and adhering, ensuring that earthworms remain intact during transportation and significantly improving the quality of the harvested product.

[0020] The entire set of equipment is compact in structure and easy to operate. Operators can be trained and put to work after simple training, which effectively reduces the threshold for manual operation and provides reliable technical support for large-scale earthworm harvesting.

[0032] Please see Figure 1-4 The present invention provides the following technical solution:

[0033] An earthworm harvesting device includes a frame 100, a harvesting device 200, a feeding cylinder 300, and a transmission device 400; the frame 100 is a flat trailer frame, and a vehicle drive system is provided on the frame 100; a control panel 101 is installed on the front right side of the frame 100, and a driving platform and an operating system are installed on the control panel 101.

[0034] A mounting frame is provided on the top of the frame 100, a harvesting device 200 is installed on the front side of the mounting frame, and a feeding cylinder 300 is installed on the rear side of the mounting frame;

[0035] The harvesting device 200 includes a conveyor belt 201 and harvesting claws 202. The conveyor belt 201 extends forward at an angle to the ground. The conveyor belt 201 is a corrugated conveyor belt with corrugated folds evenly distributed on its surface. The corrugated folds work in conjunction with the harvesting claws 202 to pick up the soil and prevent the soil from falling off during the upward transport process.

[0036] The harvesting claws 202 are located near the wavy folds. When the conveyor belt 201 rotates, the harvesting claws 202 dig up the soil and transport it to the downward cylinder 300 as the conveyor belt 201 rotates.

[0037] A material-pulling roller 203 is horizontally installed on the top of the mounting frame. Material-pulling rods are evenly distributed on the material-pulling roller 203. The material-pulling rods are located above the harvesting claw 202. When the material-pulling roller 203 rotates, it pulls up the earthworms in the soil and picks them out of the soil.

[0038] The feeding cylinder 300 is located at the rear of the harvesting device 200, and the rear end of the feeding cylinder 300 is inclined downward to facilitate the dumping of the harvested earthworms; a horn is provided at the tail end of the feeding cylinder 300.

[0039] The mounting frame is equipped with a transmission device 400, which includes a transmission machine, a transmission chain, and a transmission gear. The transmission chain connects the transmission machine and the transmission gear to realize power transmission and maintain the continuous operation of the conveyor belt 201 and the feeding roller 203.

[0040] A gear ring 301 is provided at the front end of the feeding cylinder 300, and the feeding cylinder 300 is rotatably mounted on the mounting frame. The gear ring 301 meshes with one of the transmission gears, and the feeding cylinder 300 is driven to rotate continuously at a uniform speed through the transmission device 400.

[0041] After the earthworms are pushed to the feeding cylinder 300 by the feeding roller 203, the earthworms are slowly conveyed downward by the rotation of the feeding cylinder 300. The earthworms can be continuously collected by installing a collection bucket at the rear end of the frame 100.

[0042] After the conveyor belt 201 grabs the soil and passes through the material roller 203, it continues to rotate downward. A guide plate is installed between the frame 100 and the conveyor belt 201 to guide the soil to the ground after it falls.

[0043] Hydraulic rods are symmetrically arranged on the left and right sides of the conveyor belt 201 to adjust the tilt angle of the conveyor belt 201 and adapt to breeding ridges of different heights.

[0044] The 100 chassis is made of high-strength carbon steel flat trailer frame, with a width that is compatible with the mainstream earthworm farming bed spacing. It is equipped with non-slip and wear-resistant tires at the bottom and an independent suspension system to ensure stability when driving between beds.

[0045] The drive system is equipped with a 25-30 horsepower diesel engine or a new energy electric motor, adopts a four-wheel drive mode, and supports low-speed constant speed adjustment to meet the mobility needs during harvesting operations.

[0046] The control panel 101 integrates a display instrument panel (not shown in the picture), hydraulic control lever, and emergency brake button. The driving platform is equipped with non-slip foot pedals and safety guardrails. The instrument panel can display real-time data such as engine speed, conveyor belt speed, and harvest statistics, allowing operators to monitor the equipment's operating status in real time. In addition, LED warning lights and buzzers are installed at the front and rear of the chassis to improve safety during operation.

[0047] The conveyor belt 201 is made of food-grade rubber, and anti-leakage baffles are installed on both sides of the conveyor belt 201 to prevent soil from overflowing from both sides;

[0048] The harvesting claw 202 is forged from manganese steel and has an arc-shaped structure with a blunted tip to avoid damaging earthworms. The harvesting claw 202 is horizontally fixed to the raised part of the wavy folds to ensure uniform soil gripping during excavation. The harvesting claw 202 is connected to the conveyor belt 201 using high-strength bolts for easy replacement after wear.

[0049] The feeding roller 203 is installed on the top of the mounting frame. It is made of stainless steel and its length is the same as the width of the conveyor belt. The feeding rod is made of elastic rubber and is evenly distributed on the surface of the feeding roller 203. The end of the feeding rod is equipped with an arc-shaped gripping head to enhance the separation and gripping effect of earthworms.

[0050] The guide plate has an angle of 30°-50° with the ground and a smooth coating on the surface to ensure that the soil slides down quickly and is evenly spread back onto the ridges, reducing damage to the aquaculture environment;

[0051] The feeding cylinder 300 is designed with a combination of transparent PVC material and stainless steel frame. The rear end is set with a variable diameter to form a funnel shape, which facilitates the concentrated output of earthworms. The earthworms in the feeding cylinder 300 slide down slowly under the action of gravity and rotation force to avoid congestion.

[0052] The gear ring 301 is made of high-strength alloy material, and its meshing accuracy with the transmission gear is controlled within 0.1mm to ensure smooth transmission. The feed cylinder rotation speed is set to 5-8 r / min, which reduces damage to earthworms during the conveying process and prevents earthworms from adhering to the cylinder wall.

[0053] The inner wall of the feeding cylinder is coated with an anti-stick coating to reduce friction between earthworms and the cylinder wall; the cylinder body has a reserved observation window to facilitate operators to check the earthworm conveying status in real time;

[0054] The transmission device 400 adopts a combined transmission method of motor-reduction gearbox-transmission chain. The transmission motor is a 1.5-2.2kW variable frequency motor, and the reduction gearbox has a transmission ratio of 1:20 to ensure stable output torque. The transmission chain is made of stainless steel with rust-proof surface treatment and is equipped with an automatic tensioning device to promptly compensate for slack caused by chain wear.

[0055] The transmission device 400 transmits power to the conveyor belt, the feeding roller and the feeding cylinder respectively. The transmission ratio of the conveyor belt and the feeding roller can be adjusted independently to match their speeds and improve the earthworm separation efficiency.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or basic characteristics. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of the invention is defined by the appended claims rather than the foregoing description. Therefore, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0057] Working principle:

[0058] This solution is suitable for earthworm farming fields (earthworm farming ridges), and is ideal for large-scale earthworm harvesting, saving manpower and increasing harvesting efficiency. Through mechanical linkage, soil excavation, earthworm separation, and centralized collection are achieved, completing the entire harvesting operation automatically.

[0059] The transmission device uses a variable frequency motor as its power source, and transmits power to the conveyor belt, feeding roller, and discharge cylinder through a gearbox and transmission chain. The speed of the conveyor belt and feeding roller can be adjusted independently, and the gear ring and transmission gear mesh precisely to drive the discharge cylinder to rotate at a uniform speed, ensuring coordinated operation of all components.

[0060] The vehicle frame drives the equipment to move between the breeding ridges. The conveyor belt is adjusted to a suitable tilt angle by hydraulic rods. The wavy pleats on the surface, together with the manganese steel harvesting claws, dig up the soil and prevent it from falling during transportation. The soil is conveyed upwards by the conveyor belt, and after passing through the feeding rollers, the guide plate spreads the soil back onto the ridges at an angle of 30°-50°.

[0061] When the stainless steel feeding roller rotates, the elastic rubber feeding rod uses an arc-shaped gripping head to separate earthworms from the soil. The separated earthworms fall into a transparent PVC feeding cylinder, and under the slow rotation of the feeding cylinder at 5-8 r / min and the action of gravity, they slide down the non-stick inner wall and are concentrated and output through the rear trumpet-shaped cylinder.

[0062] Operators monitor equipment operation data in real time through the control panel and make timely adjustments to achieve efficient and low-damage large-scale harvesting.

[0063] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
