Description

Technical Field

[0001] This utility model belongs to the field of flower planting machinery technology, and in particular relates to a trenching device for planting cut flower lily bulbs. Background Technology

[0002] In greenhouse lily production, trenching before bulb planting is a fundamental and crucial step. Typically, 3-4 rows are planted per bed. Traditional trenching, using a hoe, can only create one trench at a time. For large greenhouse areas, this is extremely labor-intensive and time-consuming, resulting in very low efficiency. Furthermore, workers are prone to fatigue from prolonged bending and wielding hoes, leading to high labor intensity. Manual operation is also highly susceptible to subjective factors; different workers have different trenching habits, and even the same worker cannot guarantee perfectly consistent trench spacing over extended periods. However, cut lily bulb planting requires specific trench spacing. Uneven spacing leads to irrational bulb distribution, affecting light exposure, ventilation, and growth space for the plants, ultimately reducing cut flower quality and yield. The relatively enclosed space and limited access within greenhouses hinder the use of large general-purpose agricultural machinery. Traditional manual trenching tools are rudimentary and cannot utilize the limited space for efficient operation, further restricting the large-scale and industrialized development of greenhouse cut lily cultivation. Utility Model Content

[0003] In view of the numerous technical problems existing in the current ditching technology for planting cut lily bulbs in greenhouses, this utility model provides a ditching device for planting cut lily bulbs suitable for greenhouse environments. This device can not only dig multiple planting trenches at once, significantly improving ditching efficiency, but also has the function of flexibly adjusting the trench spacing to accurately meet the planting needs of different varieties of cut lily bulbs.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] This utility model discloses a trenching device for planting cut lily bulbs, comprising a handle, a trenching hoe handle, a support tube, a crossbeam, and multiple triangular hoes. One end of the trenching hoe handle is connected to the handle, and the other end is connected to the middle position of the crossbeam via a connecting plate. Support tubes are symmetrically arranged between the two ends of the crossbeam and the trenching hoe handle. The crossbeam has a hollow groove. Multiple triangular hoe handles are installed on the crossbeam, and two triangular hoes are vertically mounted side by side along the upper edge of each triangular hoe handle, forming a double-layer trenching structure.

[0006] Furthermore, the crossbeam is made of high-strength carbon steel and has a hollow groove running through its entire length. The hollow groove has a rectangular hollow cross section, and multiple triangular hoe handles are installed in the hollow groove of the crossbeam and can be slidably adjusted along the hollow groove. The spacing between each triangular hoe handle can be adjusted within a range of 15-25cm.

[0007] Furthermore, the crossbeam is equipped with 2-5 triangular hoe handles, which can dig 2-5 planting furrows at a time.

[0008] Furthermore, the two triangular hoes are spaced 120mm apart to ensure that the trenching depth for planting lily bulbs is 15-20cm.

[0009] Furthermore, the triangular hoe is forged from isosceles high-strength manganese steel by bending along the midline of the apex, with a midline length of 200mm±10, a maximum width of 150±10mm, and a thickness of 1.5mm.

[0010] Furthermore, the bending angle α of the triangular hoe is 120°–150°.

[0011] Furthermore, the top of the triangular hoe handle has a threaded connecting rod, which is connected to the hollow groove of the crossbeam by a nut that mates with it.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. Through the reasonable structural design of this utility model, the quality and efficiency of trenching are comprehensively improved, the trench spacing is precisely controlled, the consistency of planting depth is ensured, and the labor intensity is reduced, providing strong support for the large-scale and industrialized development of facility-grown cut lilies.

[0014] 2. Improved Ditching Efficiency: Compared to the traditional manual ditching method of one ditch at a time, this utility model can install 2-5 sets of triangular hoe handles on the crossbeam, allowing for the digging of 2-5 ditches at once. With the same manpower input, the ditching speed can be increased by 2-5 times. Taking a typical one-acre greenhouse as an example, the ditching task that originally required 3 days can be completed efficiently in 1 day using this device, greatly improving work efficiency.

[0015] 3. Precise control of furrow spacing: By freely adjusting the furrowing hoe on the crossbeam, the furrow spacing can be precisely and stably controlled within the required planting range. Regardless of the variety of cut lily bulbs, it ensures that the planting furrow spacing is uniform, allowing the bulbs to receive even light, ventilation, and growing space during the growth process. This significantly improves the uniformity of cut flower quality, increasing the rate of high-quality products by more than 10% compared to traditional methods.

[0016] 4. This invention can reliably guarantee planting depth: Planting lily bulbs for cut flowers has strict requirements for soil covering. Typically, the top of the bulb needs to be covered with about 10cm of soil, and the trench depth needs to be maintained between 15-20cm. This invention, by installing a double-layered trenching hoe, can reliably guarantee consistent planting depth during the trenching process. The double-layered trenching hoe design not only enhances the strength and stability of trenching but also allows for appropriate adjustments based on different soil conditions, ensuring that the ideal depth is achieved each time. This stable planting depth provides a good foundation for the healthy growth of cut lily bulbs, promoting root development and vigorous plant growth, thereby improving the quality and yield of cut flowers.

[0017] 5. This invention significantly reduces labor intensity: Manual labor only requires pulling the device forward, eliminating the need for repeated bending and swinging of a hoe, thus reducing labor intensity. Operators can work in a relatively relaxed state, which not only improves work efficiency but also reduces physical injuries caused by prolonged high-intensity labor and extends effective working time.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Example: Figure 1-3 As shown, this utility model discloses a trenching device for planting cut lily bulbs, comprising a handle 1, a trenching hoe main handle 2, a support tube 3, a crossbeam 5, and multiple triangular hoes 6. One end of the trenching hoe main handle 2 is connected to the handle 1 for easy gripping and force application by the operator, while the other end is connected to the middle of the crossbeam 5 via a connecting plate 4. The connecting plate serves to stabilize the connection and transmit force, ensuring smooth force transmission during trenching and preventing structural loosening. Support tubes 3 are symmetrically arranged between the two ends of the crossbeam 5 and the trenching hoe main handle 2. Multiple triangular hoe handles 7 are installed on the crossbeam 5, with two triangular hoes 6 vertically arranged side-by-side along the upper edge of each triangular hoe handle 7, forming a double-layer trenching structure. The double-layer trenching structure design increases the soil breaking area and enhances trenching force, making it easier to handle soils of varying compaction.

[0024] The crossbeam 5 is made of high-strength carbon steel to ensure it is not easily deformed when subjected to trenching resistance, while also meeting the requirements of lightweight design to reduce the labor intensity of operators. The crossbeam 5 has a hollow groove running through its entire length. The hollow groove has a rectangular hollow cross section, and multiple triangular hoe handles 7 are installed in the hollow groove of the crossbeam 5, allowing for sliding adjustment along the hollow groove. The spacing between each triangular hoe handle 7 can be adjusted within a range of 15-25cm.

[0025] The length of the crossbeam 5 is designed according to the number of furrows (2-5 rows). In this example, 5 sets of triangular hoes are installed, that is, there are 5 triangular hoe handles 7 installed on the crossbeam 5, which can dig 5 planting furrows at once; the total length of the crossbeam is about 1200mm, ensuring that the spacing between each hoe handle can be adjusted within a range of 15-25cm. The top of each triangular hoe handle 7 has a threaded connecting rod, which is connected to the hollow groove of the crossbeam 5 through a matching nut, making it easy to adjust the installation spacing.

[0026] The two triangular hoes 6 are spaced 120mm apart. This reasonable spacing ensures that the trenching depth is uniform each time, guaranteeing that the trenching depth for planting lily bulbs is 15-20cm. This also ensures that the soil covering depth after planting the bulbs is appropriate, which is conducive to root development.

[0027] The support pipe 3, together with the crossbeam 5 and the main handle 2 of the trenching hoe, form a symmetrical and stable right-angled triangular structure. This triangular structure has extremely high stability. Based on the principle of mechanics, it can effectively disperse the resistance to soil penetration, prevent the device from deforming due to uneven force during trenching, and ensure the smooth progress of trenching operations. Even under relatively hard soil conditions, it can maintain structural rigidity.

[0028] This utility model uses multiple triangular hoes 6 as direct execution components for trenching. The triangular hoes 6 are forged from isosceles triangular high-strength manganese steel bent along the midline of the apex angle. The midline length is 200±10mm, the maximum width is 150±10mm, and the thickness is 1.5mm. The bending angle α of the two sides of the triangular hoe is 120°-150°. In this example, α is 120°. The midline length is 200mm and the maximum width is 145mm. This size design allows its cutting edge to effectively cut into the soil, while also possessing good wear resistance and strength, and is not easily damaged or deformed.

[0029] Example 2: This example differs from Example 1 in that two sets of triangular hoes are installed on the crossbeam 5, meaning there are two triangular hoe handles 7 installed on the crossbeam 5, capable of creating two planting furrows at once. The total length of the crossbeam 5 is approximately 450mm, ensuring that the spacing between the hoe handles can be adjusted within a range of 15-25cm. The bending angle α of the two sides of the triangular hoe described in this example is 150°, the centerline length is 210mm, and the maximum width is 155mm.

[0030] Example 3: This example differs from Example 1 in that: three sets of triangular hoes are installed on the crossbeam 5, meaning there are three triangular hoe handles 7 installed on the crossbeam 5, capable of creating three planting furrows at once; the total length of the crossbeam is approximately 650mm, ensuring that the spacing between each hoe handle can be adjusted within a range of 15-25cm. The bending angle α of the two sides of the triangular hoe described in this example is 135°, the centerline length is 205mm, and the maximum width is 150mm.

[0031] Components not described in detail in this application are all existing conventional technologies and will not be described further here.

[0032] It is understood that the above specific description of this utility model is only used to illustrate this utility model and is not limited to the technical solutions described in the embodiments of this utility model. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of this utility model.
