Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of aquaculture mechanical equipment, especially to a collecting device of a grass combing machine. BACKGROUND

[0002] In the fishpond of aquaculture, many waterweeds need to be planted to purify the water quality for the breeding of fish, shrimp and crab, and to provide natural bait and habitat. However, too dense waterweeds will bring adverse effects to the breeding of aquatic products. For example, too much waterweeds will easily cause oxygen deficiency in the shrimp and crab pond, affecting the growth of shrimp and crab, and even leading to death. Too dense waterweeds will easily cause the roots to turn yellow and black, leading to rot. Once the waterweeds rot, the water quality will deteriorate, the ecological chain will be destroyed, and not only the fishpond itself will have problems, but also the breeding results will be adversely affected, causing great economic losses. Therefore, many mechanical devices for treating waterweeds have appeared in the prior art.

[0003] For example, a waterweed collecting device of a waterweed harvester capable of preventing waterweed winding is disclosed in Chinese patent application No. 201920715273.2, which comprises a support, a driving shaft at one end of the support, a driven shaft at the other end of the support, a first driving shaft sprocket and a second driving shaft sprocket on the driving shaft, a first driven shaft sprocket and a second driven shaft sprocket on the driven shaft; a first chain between the first driving shaft sprocket and the first driven shaft sprocket, and a second chain between the second driving shaft sprocket and the second driven shaft sprocket; a waterweed conveying member between the first chain and the second chain; a first sleeve on the driven shaft that allows the driven shaft to rotate but does not move itself, or a first cutter on one side of the driven shaft for cutting off the waterweeds on the driven shaft; or a first sleeve on part of the driven shaft that allows the driven shaft to rotate but does not move itself, and a first cutter on the other part of the driven shaft for cutting off the waterweeds on the driven shaft.

[0004] For example, a crab pond special multifunctional waterweed screening machine is disclosed in Chinese patent application No. 201720123009.0, which comprises a main body support and a power transmission mechanism composed of a motor, a driving sprocket, a driven sprocket and a power chain. The motor is arranged on the main body support, the driving sprocket is fixedly connected with the output shaft of the motor, and the driving sprocket is connected with the driven sprocket through the power chain. The screening mechanism is arranged on the main body support and driven by the driven sprocket. The tension adjusting mechanism is arranged on the main body support for adjusting the tension of the screening mechanism. The cutting mechanism is rotatably connected to the main body support.

[0005] The existing devices can have certain processing capacity for waterweeds, but since the collected parts have relatively complicated structures, it is not very convenient to maintain and replace the parts, and the installation of the collecting parts is not very convenient, and the structural strength is not optimized, and for processing complex waterweeds or too many waterweeds, the device is prone to damage, and the processing effect needs to be improved.

[0024] The utility model will be further explained in detail in conjunction with the drawings.

[0025] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.

[0026] Examples, such as Figures 1-6 As shown, a collection device for a hay comber includes a frame 1. A left front sprocket 11, a left rear sprocket 12, a right front sprocket 13, and a right rear sprocket 14 are mounted and connected on the frame 1. A left chain 21 is wound on the left front sprocket 11 and the left rear sprocket 12, and a right chain 22 is wound on the right front sprocket 13 and the right rear sprocket 14. The frame 1 can be an existing hay comber frame, and the structure of the sprockets and chains can also refer to existing ones. A front rotating shaft is fixedly connected between the left front sprocket 11 and the right front sprocket 13, and a rear rotating shaft is fixedly connected between the left rear sprocket 12 and the right rear sprocket 14. The rotating shafts are all mounted and connected to the frame 1, and the mounting position will be embedded with bearings for the rotating shafts to pass through. Generally, one end of the rear rotating shaft will be connected to a power device, usually an electric motor or a diesel engine. The rear rotating shaft is the drive shaft, and the left rear sprocket 12 and right rear sprocket 14 are the drive wheels. They drive the left and right sprockets to rotate by rotating. These are all conventional structures and will not be described in detail here.

[0027] The application is characterized in that: the right side of the chain link of the left chain 21 is fixed with a left connecting reinforcing block 210, the left side of the chain link of the right chain 22 is fixed with a right connecting reinforcing block 220, and the corresponding left and right connecting reinforcing blocks 210 and 220 are detachably connected with a left and right extending collecting reinforcing crossbar 3, and the collecting reinforcing crossbar 3 is provided with a water grass collecting assembly. In the prior art, the collecting reinforcing crossbar 3 is directly fixed on the chain. In this way, when problems occur and need to be replaced and maintained, the whole needs to be moved, and all the chains and the collecting reinforcing crossbar 3 are integrally detached from the rack for processing. However, many times the fault is that one or two collecting reinforcing crossbars 3 or water grass collecting assemblies are problematic, and the other parts do not need to be processed. Therefore, the original structure is relatively troublesome in this respect, wastes manpower and material resources, and has an impact on the overall structural strength and compactness. The application introduces an excessive mounting structure, i.e. the left and right connecting reinforcing blocks 210 and 220, and through a detachable connection, the collecting reinforcing crossbar 3 can be directly disassembled on the left and right connecting reinforcing blocks 210 and 220. In this way, it has good structural independence. If a collecting reinforcing crossbar 3 or the water grass collecting assembly thereon is problematic, the collecting reinforcing crossbar 3 can be disassembled from the corresponding left and right connecting reinforcing blocks 210 and 220 for inspection, repair or replacement, etc. The convenience is greatly improved, and the overall structure is not damaged. The left and right connecting reinforcing blocks 210 and 220 can be made of metal structure, such as existing block structure made of steel, which can be fixed on the side surface of the chain link by welding, threaded connection or integral molding, etc. The detachable structure design can adopt some existing ways or new designed ways. The water grass collecting assembly can adopt existing components or new designed ways. Of course, the new designed structure will be better, not only the structure itself is optimized, but also the water grass collecting effect is better, and the use is safer, longer, more stable, etc.

[0028] Specifically, the left connecting reinforcing block 210 upper side is formed with a left mounting guide slot 2101 for placing and limiting the left end of the collection reinforcing cross bar 3 downward, and the right connecting reinforcing block 220 upper side is formed with a right mounting guide slot 2201 for placing and limiting the right end of the collection reinforcing cross bar 3 downward. The collection reinforcing cross bar 3 of the present application can not only be cylindrical but also rectangular, and generally can be a metal rod, and the left connecting reinforcing block 210 and the right connecting reinforcing block 220 can be rectangular, and the left mounting guide slot 2101 and the right mounting guide slot 2201 are determined according to the shape of the collection reinforcing cross bar 3, if the collection reinforcing cross bar 3 is cylindrical, the left mounting guide slot 2101 and the right mounting guide slot 2201 are preferably arc-shaped grooves with the opening upward, and if the collection reinforcing cross bar 3 is rectangular, the left mounting guide slot 2101 and the right mounting guide slot 2201 are preferably rectangular grooves with the opening upward, so that the assembly limiting effect is good and the assembly tightness is high.

[0029] Further, the left connecting reinforcing block 21 is provided with a left mounting hole 2102 at the bottom of the left mounting guide slot 2101 for mounting and connecting the left end of the collection reinforcing cross bar 3, and the right connecting reinforcing block 220 is provided with a right mounting hole 2202 at the bottom of the right mounting guide slot 2201 for mounting and connecting the right end of the collection reinforcing cross bar 3, the left mounting hole 2102 and the right mounting hole 2202 extend upward and downward, and the left end and the right end of the collection reinforcing cross bar 3 are both provided with an assembly hole 30 corresponding to the left mounting hole 2102 and the right mounting hole 2202 respectively, and are detachably connected by a bolt. The assembly hole 30 also extends upward and downward, and the assembly hole 30, the left mounting hole 2102 and the right mounting hole 2202 can all be threaded holes, so that by screwing a bolt into the corresponding assembly hole 30 and left mounting hole 2102 of the left end upward and downward, or by screwing a bolt into the corresponding assembly hole 30 and right mounting hole 2202 of the right end upward and downward, the detachable fixing mode of the left and right sides of the collection reinforcing cross bar 3 can be realized, and the bolt can be unscrewed for disassembly. In order to achieve the fastening effect, the threaded end of the bolt is provided with a nut, for example, the threaded rod of the bolt passes through the assembly hole 30 and the left mounting hole 2102 of the left end of the collection reinforcing cross bar 3 and then exposes the bottom end of the bottom of the left connecting reinforcing block 21 downward, and a nut needs to be screwed into the bottom end for further fixation, so that the screw head on the upper side of the bolt and the nut will clamp and fix the left end of the collection reinforcing cross bar 3 and the left connecting reinforcing block 21 upward and downward to improve the fixing effect. Of course, if the assembly hole 30, the left mounting hole 2102 and the right mounting hole 2202 are not threaded holes but smooth through holes, the bolt must be provided with a nut, otherwise it will be loose.

[0030] As preferred, the water grass collecting assembly comprises a reinforcing positioning sleeve 4 sleeved on the collecting reinforcing crossbar 3, and the elastic hook 5 is connected on the reinforcing positioning sleeve 4. Here, the water grass collecting assembly is optimized, and the reinforcing positioning sleeve 4 is designed so that the elastic hook 5 can be connected to the adjacent collecting reinforcing crossbar 3 without the need of the existing technology, the installation is relatively simple, and the structural strength is better. The existing cross connection structure is long, easy to break, and relatively troublesome to replace and maintain. The reinforcing positioning sleeve 4 of the embodiment can adopt an existing metal steel sleeve body and directly connect the elastic hook 5, thereby solving the existing problems well.

[0031] Here, the collecting reinforcing crossbar 3 is in a rectangular shape, the outer wall of the reinforcing positioning sleeve 4 is in a cylindrical shape, and the left and right through rectangular shaft holes 40 for sleeving the reinforcing positioning sleeve 4 are axially provided. Such a design limits the radial and circumferential positions of the reinforcing positioning sleeve 4, that is, the reinforcing positioning sleeve 4 cannot rotate, and the elastic hook 5 cannot rotate, thereby providing better force support.

[0032] Further, the outer wall of the reinforcing positioning sleeve 4 is formed with an annular stepped groove 41 for sleeving the elastic hook 5. Such a design makes the positioning effect of the elastic hook 5 better, and the structural stability and strength can be guaranteed.

[0033] Further, the elastic hook 5 comprises a middle U-shaped main hook body 51 and left and right torsional springs 52 and 53 integrally connected on two feet of the main hook body 51, respectively. The elastic hook 5 is made of steel and is integrally manufactured by bending and compressing through existing spring, compression spring, and torsional spring manufacturing equipment. The main hook body 51 has torsional springs on both sides in the middle. Such a structure has better balance and stability, and is more uniform in stress and less likely to be damaged. The main hook body 51 also has a better water grass collecting effect. As preferred, the left and right torsional springs 52 and 53 are fixed at the outer wall of the reinforcing positioning sleeve 4 away from the main hook body 51. The fixing can be achieved by welding, which is simple and convenient.

[0034] As preferred, the left and right sides of the reinforcing positioning sleeve 4 are connected with elastic devices 6 that can stretch and contract left and right. This design provides force buffering between the structures left and right adjacent to each other. During the water grass collecting process, there will be forces in the left and right directions, and this structure can well cope with these forces.

[0035] Further, the elastic device 6 is a compression spring or a gas spring, and the end of the elastic device 6 away from the reinforcing positioning sleeve 4 can be fixed with a buffer plastic plate h in an existing manner. The buffer plastic plate h is also sleeved on the collecting reinforcing crossbar 3, thereby protecting the elastic device 6 and reducing damage between structures.

[0036] Through the above structural design, the collection of water grass is safer and more reliable, the use of the equipment is more flexible, and the control of manpower and material resources is more reasonable, which is very suitable for modern breeding.

[0037] The above merely illustrates the specific implementation of the present application, but the protection scope of the present application is not limited to this, and any skilled person in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
