Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a harvesting device for potted leafy vegetables in greenhouses. Background Technology

[0002] In modern agricultural production, the planting and harvesting of leafy vegetables has long been a labor-intensive task. Especially in large-scale greenhouse environments, traditional harvesting methods are not only inefficient and labor-intensive, but also prone to crop damage. With the continuous advancement of agricultural technology, the market demand for automated harvesting technology is growing, making the need for automated equipment capable of efficiently and accurately harvesting leafy vegetables particularly urgent.

[0003] Although some automated harvesting equipment exists on the market, these devices still face limitations in practical applications, such as poor adaptability, complex operation, and high maintenance costs. Due to the lack of precise control mechanisms, the harvesting effect of some automated harvesting equipment is unstable, making it difficult to guarantee the integrity and quality of crops.

[0004] Therefore, this utility model is proposed. Utility Model Content

[0005] To solve the technical problems existing in the prior art, this utility model provides a harvesting device for potted leafy vegetables in greenhouses.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A harvesting device for potted leafy vegetables in a greenhouse includes two sets of opposing drive components. The drive components are arranged on channels on both sides of the seedbed, and each set of drive components includes a front wheel and a rear wheel. A first fixed rod is provided between the front wheel and the rear wheel, and a second fixed rod is provided on the front wheel. Vibrators are arranged opposite each other on the two second fixed rods, and a thin rope is provided between the two vibrators for harvesting leafy vegetables. A net is provided between the second fixed rod and the rear wheel for collecting the harvested leafy vegetables.

[0008] An adjustment assembly is provided between the two second fixing rods on both sides, and the adjustment assembly is used to adjust the distance between the two second fixing rods.

[0009] The adjustment assembly includes a telescopic rod, which includes an inner rod and an outer rod. Both the inner rod and the outer rod are provided with several holes. A fixing screw is provided between the inner rod and the outer rod, and they are fixedly connected by the fixing screw.

[0010] The adjustment assembly uses two telescopic rods.

[0011] The two telescopic rods are mounted on top of the second fixed rod, and the telescopic rods are arranged parallel to the thin rope.

[0012] The first fixing rod is parallel to the channel, and the second fixing rod is perpendicular to the channel.

[0020] The present invention will be further described below with reference to specific embodiments.

[0021] In the following description, all directional (or orientational) concepts involving up, down, left, right, front, and back refer to the position of the figure being described, and are intended to facilitate public understanding. Therefore, they should not be construed as a special limitation on the technical solution provided by this utility model.

[0022] like Figure 1 As shown, a harvesting device for potted leafy vegetables in a greenhouse includes two sets of opposing drive components. The drive components are set on the channels 2 on both sides of the seedbed 1, and each drive component includes a front wheel 3 and a rear wheel 4. A first fixing rod 5 is provided between the front wheel 3 and the rear wheel 4, and a second fixing rod 6 is provided on the front wheel 3. Vibrators 7 are arranged opposite to each other on the two second fixing rods 6, and a thin rope 8 is provided between the two vibrators 7. The thin rope 8 is used to harvest leafy vegetables 11 (the height of the vibrators 7 can be adjusted according to the height of the leafy vegetables 11 so that the thin rope 8 can effectively cut the leafy vegetables 11). A net bag 9 is provided between the second fixing rod 6 and the rear wheel 4. The net bag 9 is used to collect the harvested leafy vegetables 11.

[0023] An adjustment assembly is provided between the two second fixed rods 6 on both sides. This assembly is used to adjust the distance between the two second fixed rods 6, thus adapting to flexible harvesting of seedbeds 1 with different widths. The adjustment assembly includes a telescopic rod 10, which comprises an inner rod and an outer rod. Both the inner and outer rods have several holes, and a fixing screw is provided between them for secure connection. The harvesting device disclosed in this application uses two telescopic rods 10 for its adjustment assembly. The two telescopic rods 10 are positioned at the top of the second fixed rods 6 and are parallel to the thin rope 8. The first fixed rod 5 is parallel to the channel 2, and the second fixed rod 6 is perpendicular to the channel 2, forming a right-angle structure between the first fixed rod 5 and the second fixed rod 6 to ensure the stability of the harvesting device.

[0024] The four corners of the opening of the net bag 9 are fixed to the second fixing rod 6, forming a rectangular structure. The middle part of the net bag 9 extends to the rear wheel 4, and the two ends of the closed part of the net bag 9 are detachably connected to the rear wheel 4, so that the net bag 9 forms a triangular collection space. The opening of the net bag 9 is also designed to cooperate with the thin rope 8, so that the cut leafy vegetables 11 can slide smoothly into the net bag 9.

[0025] The working principle is as follows:

[0026] First, prepare the necessary components, including: two telescopic poles 10, four wheels, a net 9, a vibrator 7, a thin rope 8, etc., and ensure that the quality and size of the required components meet the requirements.

[0027] Next, assemble the harvesting device. First, place the second fixing rods 6 perpendicular to the channels 2 on both sides of the seedbed 1. The two second fixing rods 6 are used to fix the telescopic rod 10 and install the vibrator 7. At the bottom of each second fixing rod 6, install a first fixing rod 5 parallel to the channels 2 on both sides of the seedbed 1. Install wheels at the bottom of both ends of the first fixing rod 5, namely the front wheel 3 and the rear wheel 4, to ensure that the four wheels can rotate freely so that the cutting device can move on the seedbed channel 2.

[0028] Based on the height of the leafy vegetables 11 placed on the seedbed 1, a vibrator 7 is fixed on each of the two second fixed rods 6. The two ends of the thin rope 8 are fixed on the two vibrators 7 respectively, and the installation positions of the two vibrators 7 should be symmetrical to ensure that the vibration energy is evenly distributed. At the same time, the thin rope 8 forms a horizontal working surface to ensure that the tension of the thin rope 8 is moderate so that the thin rope 8 can effectively cut the leafy vegetables 11 under the action of vibration.

[0029] The two ends of the two telescopic rods 10 are respectively fixed to the second fixed rod 6, generally at the top of the second fixed rod 6, ensuring that the telescopic rods 10 are parallel to the thin rope 8 and span the seedbed 1. The design of the telescopic rods 10 allows the thin rope 8 to be adjusted according to the width of the seedbed 1. Both the inner and outer rods of the telescopic rods 10 have several holes. After aligning the holes on the inner and outer rods, they are fixed together with fixing screws.

[0030] Finally, the four corners of the net 9 are fixed to the second fixing rod 6, forming a rectangular structure. The central part of the net 9 extends to the rear wheel 4, forming a triangular collection space.

[0031] Specifically, the vibrator 7 can be started first, and the vibration frequency and intensity can be adjusted to ensure that the thin rope 8 vibrates regularly under the combined action of the two vibrators 7. Then, the length of the telescopic rod 10 can be adjusted. That is, first loosen the fixing screws, move the inner rod of the telescopic rod 10 to the required hole position, and ensure that the inner rod and the outer rod are aligned. After adjustment, fix the inner rod in the selected hole position with the fixing screws to ensure that the telescopic rod 10 remains stable during the harvesting process.

[0032] The harvesting device moves back and forth along the channels 2 on both sides of the seedbed 1. This can be done manually or by motor-driven wheels. Simultaneously, the vibration of the thin rope 8 acts on the stems of the leafy vegetables 11, precisely cutting them at the root and guiding them smoothly into the net bag 9 at the rear. After harvesting, the two fixing points on the rear wheel 4 are released, and the net bag 9 automatically springs back, collecting and baling the harvested leafy vegetables 11.

[0033] The core technology of this application lies in the precise harvesting of leafy vegetables 11 using a vibrating string 8. The string 8 is connected between two vibrators 7. When the vibrators 7 are activated, the string 8 vibrates rhythmically under the combined action of the two vibrators. As the harvesting device moves along the seedbed channel 2, the vibration of the string 8 acts on the stem of the leafy vegetables 11. Through precise vibration frequency and force, the leafy vegetables 11 can be effectively cut and guided smoothly into the net bag 9 behind. This design ensures minimal damage to the leafy vegetables 11 during harvesting, while improving the continuity and efficiency of harvesting.

[0034] The telescopic rod 10 is designed to allow the harvesting device to adapt to tidal seedbeds 1 of varying widths, ensuring that the wheels on both sides can be precisely positioned on the channels 2 on both sides of the seedbed 1, thus enabling flexible harvesting of seedbeds 1 of different widths. This design fully considers the characteristics of the channels 2 on both sides of the seedbed 1, ensuring that the wheels can pass smoothly without interfering with the tidal irrigation system.

[0035] The harvesting device disclosed in this application has a significant advantage in cost, and its design is simple, easy to maintain and repair. Compared with existing automated harvesting equipment on the market, this new harvesting device also performs well in terms of cost control and ease of operation, thereby further improving its economic benefits and market competitiveness.

[0036] The above content is a further detailed description of the technical solution provided in conjunction with the preferred embodiments of this patent. It should not be considered that the specific implementation of this utility model is limited to the above description. For those skilled in the art to which this patent pertains, several simple deductions or substitutions can be made without departing from the concept of this patent, and all of these should be considered to fall within the protection scope of this patent.
