Description

Technical Field

[0001] The invention relates to the technical field of leaf vegetable harvesters, in particular to a leaf vegetable harvester which is convenient for guiding and conveying. Background Art

[0002] Leafy vegetable harvesters are integrated mechanisms used for harvesting, conveying and packaging leafy vegetables. The use of harvesters is generally divided into two categories according to their purpose and the effect to be achieved. One is a machine used in leafy vegetable planting sites to pick and collect leafy vegetables in the planting area, and the other is leafy vegetable collection, transportation and packaging equipment used in soilless cultivation or centralized planting. The two are used in different scenarios and have different effects. Classification is convenient for batch harvesting of leafy vegetables in agricultural planting.

[0003] For example, the existing Chinese patent with publication number CN117859510A, entitled "A cutting table profiling adjustment device and adjustment method for leafy vegetable harvesters", realizes adaptive profiling of the height of the cutting table from the ground and the attitude angle of the cutting table by determining the extension and contraction amount of two electric cylinders; it uses the cutting table to harvest leafy vegetables planted on the ground, but in practice, the following problems still exist:

[0004] Leafy vegetables are collected by leafy vegetable harvesters. However, since leafy vegetables are planted in centralized locations, the harvested and transported leafy vegetables are piled up in a centralized location during the collection process. As a result, the leafy vegetables are severely compressed during transportation and cannot be dispersed. The leafy vegetables inside the pile are easily spoiled due to the temperature of the centralized pile, affecting subsequent collection. At the same time, the concentrated piled leafy vegetables are not conducive to humidification and moisturizing treatment. During the continuous operation of the harvester, they are prone to deterioration and water loss.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original leafy vegetable harvester. Summary of the invention

[0006] The object of the present invention is to provide a leafy vegetable harvester which is easy to guide and transport, so as to solve the problem that the existing leafy vegetable harvester proposed in the above background technology is not conducive to the transportation of leafy vegetables. During the transportation, the leafy vegetables will be concentrated and piled up, which is not conducive to humidification and moisturizing treatment. During the continuous operation of the harvester, the leafy vegetables are prone to deterioration and water loss.

[0007] To achieve the above object, the present invention provides the following technical solution: a leaf vegetable harvester that is convenient for guided transportation, comprising:

[0009] It also includes: a water vapor pressurizing assembly, which is fixed on the outer side wall of the harvester body, the air outlet of the water vapor pressurizing assembly is connected with a connecting pipe, the connecting pipe is rotatably connected with the rotating drum, wherein the frame-type cross pipe is connected with the rotating drum and the blocking block through the inside of the hose;

[0010] The exhaust port is arranged at the front bottom of the blocking block, and a pressure valve assembly is also fixed on the back of the blocking block, and the pressure valve assembly is communicated with the pressure relief port at the rear bottom of the blocking block.

[0011] Preferably, the communicating pipe is provided with protruding tubes corresponding to the rotating drum one by one, the protruding tube and the rotating drum are coaxially distributed rotating structures, and the rotating connection between the two is positioned by a sealed bearing.

[0012] Preferably, a screw assembly is also fixed on the outer wall of the rotating drum, and the screw in the screw assembly component is connected to the end of the frame-type cross tube by a through-threaded connection.

[0013] Preferably, the side of the blocking member facing the leafy vegetables is arranged in an arc-shaped concave shape, and a guide roller is rotatably mounted on the bottom thereof.

[0014] Preferably, the guide roller is assembled and distributed in multiple sections, annular permanent magnets with magnetic repulsion distribution are arranged between the head and tail ends of two adjacent sections of the guide roller, and a fine brush is arranged on the outside of the guide roller.

[0015] Preferably, the exhaust ends are evenly distributed at equal intervals at the bottom of the blocking block, and the through connection between the exhaust ends and the blocking block is arranged in an arc-shaped spiral shape, and the air outlet of the exhaust end is arranged in contact with the arc-shaped outer wall of the blocking block.

[0016] Preferably, the middle section of the frame-type cross tube is configured to be telescopic, wherein an elastic return spring is installed inside the telescopic portion of the middle section of the frame-type cross tube.

[0017] Preferably, the pressure valve assembly is configured as a conventional pressure valve component, which is used to prevent the barrier from being connected to the inside of the exhaust end when the internal air pressure of the barrier is overloaded, so as to discharge the overloaded air pressure inside the barrier.

[0018] Preferably, the blocking member is connected to the interior of the pressure valve assembly and the pressure relief port in sequence, a sliding rod is vertically fixed inside the pressure valve assembly, a sealing plug is slidably installed on the outside of the sliding rod, an elastic member is fixed between the back of the sealing plug and the inner wall of the pressure valve assembly, and the sealing plug is used to seal the connection between the blocking member and the pressure valve assembly.

[0019] Preferably, damping strips are fixed at equal intervals on the outer wall of the sliding rod, and the damping strips and the inner wall of the middle part of the sealing plug are connected to form a damping arrangement.

[0020] Compared with the prior art, the beneficial effects of the present invention are: the leaf vegetable harvester that is easy to guide and transport can perform guided transportation during the leaf vegetable harvesting process, and perform dispersion processing of the leaf vegetables during the transportation process, and realize humidification and moisture retention processing during the dispersion process, and the specific contents are as follows:

[0021] 1. The height of the conveying crawler on the harvester body is limited by the rotatably installed frame cross tube and the blocking member at its end, so that the leafy vegetables transported on the conveying crawler are initially dispersed to prevent excessive accumulation of leafy vegetables during transportation, which would cause the conveying crawler to be subjected to concentrated force at a local position, affecting the transmission efficiency, stabilizing the guiding and conveying effect and extending its service life;

[0022] Furthermore, the blocking member is arranged in an arc-shaped structure, and the bottom portion thereof is rotatably installed with a guide fine roller, so that the blocking member utilizes a shearing force to more conveniently disperse the accumulated leafy vegetables and prevent accumulation, and at the same time can reduce the contact friction between the bottom of the blocking member and the leafy vegetables, effectively reducing the damage to the leafy vegetables caused by external forces during the dispersion process;

[0023] 2. At the same time, the inner space of the barrier is set, and it can introduce the pressurized water vapor from the outside through the frame-type horizontal pipe and pipeline components. The water vapor is discharged from the exhaust end on the barrier, and the water vapor forms a barrier air cover on the outside of the barrier, which can reduce the contact friction with the leafy vegetables and accelerate the dispersion of the leafy vegetables. At the same time, the harvested and dispersed leafy vegetables can be humidified and moisturized at the same time. The dual process is carried out simultaneously to achieve the protection of leafy vegetables during the harvesting process;

[0024] Furthermore, a matching pressure valve assembly and a pressure relief port are provided on the back of the barrier. When the exhaust end is blocked due to excessive leafy vegetables transported by the conveying track, the air pressure in the barrier can be discharged to realize the exhaust operation. At the same time, while the exhaust operation is in progress, the pressure of the exhaust steam can be released to cause the barrier to be flipped and the large amount of accumulated leafy vegetables can be quickly dispersed, thereby further stabilizing the transportation stability of the leafy vegetables and the humidification and moisturizing treatment efficiency.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figure 1-Figure 6 The present invention provides a technical solution: a leaf vegetable harvester that is convenient for guided transportation, comprising: a harvester body 1, a conveying crawler movably installed on the top of the harvester body 1, and a rotating drum 2 is rotatably installed on the front and rear outer walls of the harvester body 1, one end of a frame-type horizontal pipe 3 is connected to the rotating drum 2, and a blocking member 4 is fixed to the other end of the frame-type horizontal pipe 3;

[0038] By adopting the above technical scheme, the harvesting component at the front end of the harvester body 1 is used to collect the cultivated leafy vegetables. The harvesting component adopts the technical structure in the existing technical scheme and does not make any technical improvements thereto. Therefore, the detailed structure and use method of the harvesting component are not described in detail in this technical scheme. After the harvesting component harvests the cultivated leafy vegetables, it will be transported to the conveying crawler at the top of the harvester body 1 to transport the leafy vegetables.

[0039] The technical solution also includes: a water vapor pressurizing component 5, which is fixed on the outer wall of the harvester body 1, and the air outlet of the water vapor pressurizing component 5 is connected with a connecting pipe 6, and the connecting pipe 6 is rotatably connected with the rotating drum 2, wherein the frame-type cross pipe 3 is connected with the rotating drum 2 and the blocking block 4 through the inside of the hose; a screw assembly 301 is also fixed on the outer wall of the rotating drum 2, and the screw in the component of the screw assembly 301 is connected with the end of the frame-type cross pipe 3 by a through-threaded connection; the side of the blocking block 4 facing the leafy vegetables is set in an arc-shaped concave shape, and a guide fine roller is also rotatably installed at its bottom 401; the guide roller 401 is assembled and distributed in multiple sections, and an annular permanent magnet with magnetically repelling distribution is arranged between the ends of the two adjacent sections of the guide roller 401, and a fine brush is arranged on the outside of the guide roller 401; the exhaust end 7 is evenly distributed at equal intervals at the bottom of the blocking block 4, and the through connection between the exhaust end 7 and the blocking block 4 is arranged in an arc-shaped spiral shape, and the air outlet of the exhaust end 7 is arranged in contact with the arc-shaped outer wall of the blocking block 4; the middle section of the frame-type cross tube 3 is arranged in a telescopic shape, wherein an elastic reset spring is also installed inside the telescopic part of the middle section of the frame-type cross tube 3;

[0040] In the above technical solution, if Figure 1 and Figure 5 As shown, according to the difference in the concentration of planted leafy vegetables in the area used by the harvester, the maximum amount of leafy vegetables concentrated on the conveyor crawler can be limited, that is, the difference in the distance between the blocking member 4 and the conveyor crawler is used to adjust the amount of leafy vegetables accumulated on the conveyor crawler to prevent the formation of concentrated accumulation of leafy vegetables at local positions on the conveyor crawler when the leafy vegetables are collected, resulting in stress concentration at local positions during the use of the conveyor crawler, affecting the normal use of the conveyor crawler, and causing damage due to stress concentration during use; and by Figure 5 As shown, the screw assembly 301 can be used to adjust the horizontal position of the frame-type cross tube 3 and change the positioning height of the blocking block 4; at the same time, when the conveyor belt is conveying leafy vegetables, the leafy vegetables move to the position of the blocking block 4, and the arc-shaped blocking block 4 can use the shearing external force to disperse the accumulated leafy vegetables. The dispersed leafy vegetables pass through the bottom and top of the blocking block 4 respectively, and the leafy vegetables passing through the bottom of the blocking block 4 are conveyed under the action of the guide fine roller 401, thereby reducing the squeezing contact friction during the dispersion of the leafy vegetables and achieving the protection of the leafy vegetables. At the same time, the segmented guide fine roller 401 has a smaller damping external force when dispersing leafy vegetables in different areas, and is more protective of the leafy vegetables themselves; at the same time, in the present technical solution, a telescopic frame-type cross tube 3 is also provided, so that when the blocking block 4 contacts and disperses the leafy vegetables, the impact external force is reduced, thereby achieving the protection of the leafy vegetables under the buffering effect.

When a large number of concentrated leafy vegetables are dispersed, the leafy vegetables are subjected to a large shear force due to the blocking and dispersion of the blocking block 4 due to the excessive concentrated weight of the leafy vegetables. The rotation of the frame-type horizontal tube 3 can be used to unload the stress impact external force during the dispersion of the leafy vegetables, release the load, protect the structure from damage, and also protect the leafy vegetables;

[0044] The exhaust port 7 is arranged at the front bottom of the blocking block 4, and a pressure valve assembly 8 is also fixed on the back of the blocking block 4, and the pressure valve assembly 8 is connected with the pressure relief port 9 at the rear bottom of the blocking block 4; the pressure valve assembly 8 is set as a conventional pressure valve component, which is used to connect the blocking block 4 and the exhaust port 7 when the internal air pressure of the blocking block 4 is overloaded, and discharge the overloaded air pressure inside the blocking block 4;

[0045] In the above technical solution, if Figure 1 and Figure 7 , Figure 8 As shown, when the barrier baffle 4 is in use, water vapor can be introduced into the barrier baffle 4 through the water vapor pressurizing component 5, and the pressurized water vapor is discharged through the exhaust port 7 on the barrier baffle 4 to form a water vapor protection layer on the outer surface of the barrier baffle 4, so that when the barrier baffle 4 disperses the leafy vegetables, the contact friction between the two is reduced to protect the leafy vegetables, and the water vapor can also be discharged at the same time, and the leafy vegetables are humidified and moisturized during the dispersion process to achieve the protection of the leafy vegetables; at the same time, when the leafy vegetables are harvested in excess, the leafy vegetables will cause the exhaust port 7 to be blocked, resulting in excessive air pressure in the barrier baffle 4, a pressure valve component 8 and a pressure relief port 9 are provided, when the internal air pressure of the barrier baffle 4 is too high, the pressure can be relieved through the pressure relief port 9 to reduce the adverse effects caused by the blockage of the exhaust port 7, and at the same time, the pressure relief of the pressure relief port 9 can be used, so that the impact kinetic energy drives the barrier baffle 4 to flip during the pressure relief process, so that the leafy vegetables accumulated thereon are shaken off, and the dispersion effect of the leafy vegetables is further improved.

[0046] Embodiment 3: Different from Embodiment 2, the present invention discloses another form of pressure valve assembly 8, wherein the blocking member 4 is connected with the pressure valve assembly 8 and the pressure relief port 9 in sequence, a sliding rod 801 is vertically fixed inside the pressure valve assembly 8, a sealing plug 802 is slidably installed on the outer side of the sliding rod 801, an elastic member 803 is fixed between the back of the sealing plug 802 and the inner wall of the pressure valve assembly 8, and the sealing plug 802 is used to block the connection between the blocking member 4 and the pressure valve assembly 8; damping strips 804 are also fixed at equal intervals on the outer wall of the sliding rod 801, and the inner wall of the middle part of the damping strip 804 and the sealing plug 802 is a damping setting;
