Description

Technical Field

[0001] This invention relates to the field of chain drive technology, specifically to a conveyor chain for a crop grain lifting machine. Background Technology

[0002] Currently, crop lifting machines primarily operate using lifting scrapers on a chain to transport crops or grains. The lifting scrapers have a U-shaped structure, spanning both sides of the chain and connected to auxiliary plates on either side of the chain via bolts. The chain drives the lifting scrapers in a cyclical movement, transporting the crops or grains within the housing containing the chain.

[0003] However, existing technologies have the following drawbacks:

[0004] 1. The grain scraper is made of the same material as a car tire, which is very hard. During use, it is very easy to hit and damage the fruits on the stems and ears of crops, resulting in loss and waste.

[0005] 2. The grain scraper is a functional component that comes into contact with the stems and ears of crops during use. Because it is a U-shaped plate structure that spans both sides of the chain, grain or crop debris can easily enter between the inner opening of the U-shape and the chain, causing blockage and resulting in low overall conveying efficiency. Utility Model Content

[0006] This invention discloses a conveyor chain for a crop lifting machine, the purpose of which is to solve the problems described in sections 1 and 2 of the background art.

[0007] To achieve the above objectives, the technical solution of this invention is as follows:

[0008] A conveyor chain for a crop lifting machine includes a chain body, on which several pairs of auxiliary plates are equally spaced. Each pair of auxiliary plates includes auxiliary plate bodies arranged opposite each other on both sides of the chain body. The top of the two auxiliary plate bodies is connected to a lifting bucket structure, and the upper end and front end of the lifting bucket structure are open.

[0009] Preferably, the grain lifting hopper structure includes a bottom plate, side plates, and a back plate. The bottom plate has two side plates fixedly connected to its upper sides, and the back of the two side plates is integrally connected to the back of the back plate. The bottom end of the back plate is connected to the rear end of the bottom plate through an arc plate. The two ends of the arc plate and the side plates form a sealing structure. The bottom plate is fixedly connected to two oppositely arranged auxiliary plate bodies through bolt and nut assemblies. The back plate has a structure that is inclined to the forward side.

[0010] Preferably, the height of the grain lifting hopper structure is ≥88mm, the angle between the back plate and the bottom plate is 50°, the top of the side plate is an arc-shaped structure, and the radius (R) of the arc-shaped plate is 22°.

[0011] Preferably, the width of the base plate is greater than the width of the chain body and is located directly above the chain body. The side plates are perpendicular to the base plate or tilted outward. When the side plates are tilted outward, the maximum included angle between the two side plates is 50°.

[0012] Preferably, the bottom plate has flow dividers on the left and right sides of its rear end, which transition to the arc-shaped plate side, and the two flow dividers are located on both sides of the chain body.

[0013] Preferably, the attachment plate includes a connecting part for connecting with the chain body. The connecting part has two first mounting holes. The top center of the connecting part extends upward to form an extension. The attachment plate body is bent from 1 / 2 of its overall height to form an outwardly folded and horizontally oriented support part. The bending position is located on the extension part. The support part has a first connecting hole. The bottom plate has second connecting holes on both sides. Bolts pass through the first and second connecting holes. The bolt nuts are located above the bottom plate. Washers are provided between the bolt nuts and the bottom plate. The bolts pass through the washers. Nuts are tightened on the bolts and abut against the lower surface of the support part.

[0014] Preferably, the chain body is a roller chain, including an inner chain plate, an outer chain plate, a pin, a sleeve, and rollers. Two inner chain plates are arranged opposite each other and assembled with the sleeve and rollers to form an inner chain link. Two outer chain plates are arranged opposite each other and assembled with the pin to form an outer chain link. The inner chain links and outer chain links are connected in series by the pin. The connecting part of the auxiliary plate body replaces part of the outer chain plate of the outer chain link. Two first mounting holes are respectively interference-fitted with the ends of the pin.

[0015] The beneficial effects of this new type of conveyor chain for a crop lifting machine:

[0016] 1. Protecting the fruit: Due to the relatively soft structure of the grain lifting bucket, it reduces the impact on crops during operation, thus avoiding damage to the crop fruit.

[0017] 2. High conveying efficiency: Due to the hollow structure of the grain hopper, a large amount of fruit can be stored during transportation, which greatly improves the conveying efficiency.

[0018] 3. Avoid material blockage: Due to the change in the way crops are transported and the diversion trough design of the grain storage hopper, the problem of material blockage in the chain body during the lifting and conveying of crops is effectively avoided. Attached Figure Description

[0033] In this embodiment, as Figure 3 , 4 As shown, the grain hopper structure 3 includes a bottom plate 32, side plates 31, and a back plate 33. The two sides of the upper end of the bottom plate 32 are respectively fixedly connected to the side plates 31. The back plate 33 is integrally connected to the back of the two side plates 31. The bottom end of the back plate 33 is connected to the rear end of the bottom plate 32 through an arc plate 37. The two ends of the arc plate 37 and the side plates 31 form a sealing structure. The bottom plate 32 is fixedly connected to two oppositely arranged auxiliary plate bodies by bolt and nut assemblies. The back plate 33 has a structure that is inclined to the forward side.

[0034] In this embodiment, as Figure 1-4 As shown, the height of the grain lifting hopper structure 3 is ≥88mm, the angle between the back plate 33 and the bottom plate 32 is 50°, the top of the side plate 31 is an arc-shaped structure 38, and the radius of curvature of the arc-shaped plate 37 is 22°.

[0035] In this embodiment, as Figure 1-4 As shown in Figures 9 and 1, the width of the base plate 32 is greater than the width of the chain body 1 and is located directly above the chain body 1. The side plate 31 is perpendicular to the base plate 32 or tilted outward. When the side plate 31 is tilted outward, the maximum included angle between the two side plates 31 is 50°.

[0036] In this embodiment, as Figure 1-4 As shown in Figures 9 and 1, the left and right sides of the rear end of the base plate 32 are respectively provided with diversion grooves 35 that transition to the side of the arc plate 37. The two diversion grooves 35 are located on both sides of the chain body 1 to prevent the diverted crops or grains from clogging the chain.

[0037] In this embodiment, as Figure 1 , 5 As shown in Figure -9, the auxiliary plate body includes a connecting part 21 for connecting with the chain body 1. The connecting part 21 is provided with two first mounting holes 24. The top center of the connecting part 21 extends upward to form an extension part 22. The auxiliary plate body is bent from 1 / 2 of its overall height to form an outwardly folded and horizontally oriented support part 23. The bending position is located on the extension part 22. The support part 23 is provided with a first connecting hole 25. The bottom plate 32 is provided with second connecting holes 34 on both sides (e.g., ...). Figure 3As shown), the first connecting hole 25 and the second connecting hole 34 are penetrated by bolts 4. The nuts of the bolts 4 are located above the base plate 32. A washer 6 is also provided between the nuts of the two bolts 4 and the base plate 32 (e.g., Figure 9 As shown), the bolt 4 passes through the washer 6, and the nut 5 is tightened on the bolt 4 and abuts against the lower surface of the support part 23.

[0038] In this embodiment, as Figure 1 , 9 As shown, the chain body 1 is a roller chain, including inner chain plates 11, outer chain plates 14, pins 15, sleeves 12, and rollers 13. Two inner chain plates 11 are arranged opposite each other and assembled with sleeves 12 and rollers 13 to form inner chain links (this is prior art; that is, the inner chain plates have two second mounting holes, two sleeves are connected between two opposite inner chain plates, the two ends of the sleeves are interference-fitted with the corresponding second mounting holes, and the rollers are sleeved outside the sleeves and have a clearance fit with the sleeves). Two outer chain plates are arranged opposite each other and assembled with pins to form outer chain links (i.e.,...). The outer chain plate has two third mounting holes, and two pins connect the two outer chain plates (the ends of the pins are press-fitted with the third mounting holes). The inner and outer chain links are connected in series by pins (i.e., the pin of the outer chain link passes through the sleeve of the adjacent inner chain link and is clearance-fitted with the sleeve). The connecting part 21 of the auxiliary plate body replaces part of the outer chain plate of the outer chain link (i.e., the connecting parts of two oppositely arranged auxiliary plate bodies are connected to two pins to form an auxiliary plate chain link to replace the outer chain link). The two first mounting holes 24 are press-fitted with the ends of the pins 15 respectively. It should be noted that the replacement of the outer chain plates by the auxiliary plate body is usually at equal intervals, thus forming a structure on the chain body with equally spaced grain lifting hoppers connected by auxiliary plates.

[0039] In this embodiment, as Figure 1 , 9 As shown, the grain lifting hopper structure is made of PP+EPDM+T20 (modified polypropylene) material.
